He makes a great point about water in a diesel engine. In high school I attended a diesel mechanics course. We had a piston that had come out of a Cummins diesel from an 18 wheeler that had water ingestion damage. The compression ratio is so high in diesel engines that drops of water become the equivalent of a steel ball bearing banging up and down in the cylinder. The top of that piston looked like it was beat hard with a tiny ball peen hammer. Literally hundreds of little dents. Amazing.
@@conorcleary2100 A man I know started to explain... then half way through he went completely insane. I still see him every now and then... during visiting hours.
Couldn't agree more about the low range crawling. Petrol does require alot more clutch work to do the same crawling. But a set of reduction gears changes everything. I'm able to crawl alot better now than most other 4wd's and the low range gears are still usable for mud and boggy sand. Would hate a low revving diesel with the same ratios. Petrol also has the panic button if you get worried about getting stuck you almost always have 2000-4000rpm more to rev out haha. Water is far less a problem with petrols as it used to be. I would even say it's on par comparing two modern vehicles. Coil packs tend go hold out the water well.
There is another point of consideration that was not raised in this video. And that is, recovery from roll-over. When doing rock-crawling, jumping sand dunes, climbing hills, that sort of thing. If you roll your off-road vehicle upside down, and then roll it back upside up, while the engine was inverted, oil from the oil pan seeped past the piston rings and have filled the cylinders with oil. With a gasoline (or petrol, depending on the terminology used in your country), you can just remove the spark plugs, crank the engine a few revolutions, replace the spark plugs, and be on your way. With a diesel, removing the glow plugs (if equipped), or fuel injectors are more difficult. I have both Gasoline and Diesel vehicles, one of my diesel trucks doesn't even have glow plugs, and the injectors are difficult to get to. If the cylinders filled with oil, I would have to either come back with more tools, or have it towed. The gasoline, with the spark plugs, much easier.
Here in the States, we don't have a lot of smaller diesels like the rest of the world (though they are starting to catch on as of late), so most diesels are the big, towing type. They have massive, heavy blocks that weigh a ton and severely hamper offroad performance. They are not well balanced, they tend to sink into mud, sand, and snow much worse than a gasoline engine vehicle, and they wear out tires faster. The most serious offroad vehicles here (both stock and custom built) are gasoline powered.
I have owned a 62 series 3f '86 on gas/petrol on 33" muddies for 20 years now, done around 600k still going well, no rebuild, no oil use, not quick but super reliable and torque, gas keeps it cheap. Many Deisels of the time have had very expensive rebuilds done at 300k. I'm not complaining.
To be fair, Toyota designed all engine variations for both the 60 and 80 series to be 1,000,000 km engines before a major rebuild. So apples with apples on this argument 🤷🏼 we can all agree that the difference between petrol and diesel reliability is tiny in comparison with the reliability difference between Toyota and Nissan 😅
You either invest in diesel and hope to get the increased cost of initial purchase and increased cost of fuel and maintenance back through reduced fuel consumption or you by a petrol for significantly less initial cost and less maintenance cost and less fuel cost(per litre) at the pump and hope you don't eliminate the savings through greater fuel consumption. Modern day petrol engines are so efficient that it makes the choice harder than it was say 10 years ago.
I have an easier way to differentiate them: If you want to buy a van or a full size SUV, no matter you drive off-road or not, diesel will win on economy. If not, petrol will win.
@@wangjialei1985 Economy - in what sense? Less fuel for diesel, but if something goes wrong with new diesels DPF, EGRs, dual mass, AdBlue etc the savings disappear.
Waldemar Ishibashi Diesel engines are more difficult to maintain, that's true. So you can't use other replacements (some new types of diesel didn't pass the long-term test) before they are proved to be safe.
i couldnt go to the simpson in my bronco,f250,f100, because they were petrol.fire hazard.but,non of them have cats,diesels have cats.i call bullshit to everything these days..
Hi Ronnie Great video. Just a thought that you could have included service regularity. Diesel certainly require more regular oil changes to ensure longevity. And the reason for diesels being built stronger is mainly because of the higher compression ratio. Not only does the DPF - DPD get hotter but the gas coming from the exhaust is extremely hot too. I worked for a well known Japanese brand of truck for 10 years and when they introduced the DPD in 2008 we brought up the problem of exhaust temps while regenerating. We were told it wouldn’t be a problem. We tested a truck during a break in our training and got it to do a manual regeneration. We lit a cigarette by holding at the end of the exhaust. No problem? We were then instructed to advise customers not to park the vehicle next to anything flammable with the engine running. Rural Fire Service stopped buying the trucks saying that their job is to put out fires not to start them. Thanks again for the videos
I dont know how it is in Australia,but in Germany we have a lot of grass around our rivers.So when you fight through a river you encounter high grass.Maybe thats how he came to that point XD
Also, just thought of the point about exhaust. Diesel engines run cooler on the way out of the engine, and in a gasoline engine, the components can get VERY hot. When attempting a deep water crossing in a petrol/gas engine, you sometimes need to shut the engine off to let it cool. Crossing deep water that is cold like near a mountain river/creek, can break exhaust pipes and other components because of the large change in temperature.
My gasoline 4x4 manual 4Runner is 20 years and 262, 861 miles of age (2000 through 2020, so far). She's been working search and rescue in northern Arizona most of that time, on highway getting to the forest road; forest road and trail getting to the location of rescue. Her low and low/low 4x4 gears have so far gotten us to our subject still alive. What's this about 4 years? One more thing. I also had a 2011 Silverado long bed switchable AWD diesel. Here in the States, diesel exhaust fluid is now required.
Well done being brave and taking on this subject. So many people will have issue with your science. I don't, as I know what you are trying to get across.
Great video again with lots of good points, mate! But from a foreign (German) subscribers point of view, you missed some important issues, especially regarding modern diesels: You will mostly have to use ad-blue (DEF) and all the pain-in-the-ass issues with DPF to meet the modern exhaust standards of diesel engines. From now on, you can not even register a diesel Landcruiser in Germany anymore, because the motor does not comply with the latest regulations. Only petrol powered LandCruisers models are imported as new. And with older diesels you are not even allowed to enter some European cities anymore. The German company Extrem Fahrzeuge even sells an electric bush taxi version. Unfortunately, due to the low range (nowadays) this is interesting just for mining company's etc. but not for long distance travels. Hope batteries will improve soon so it will be THE kind of drive ruling out petrol and diesel.... Another issue for overlanders: Diesel is not always so easily available around the world, e.g. not in Usbekistan, difficult in Iran, or even not everywhere in the US.... Additionally, the diesel quality (sulphur & water content...) can be very bad in some areas and you may wreck your engine. If you are unlucky and get the diesel pest into your whole distribution system, you'll have a big hole in your pocket. This may even happen in Europe due to the bio diesel with its high content of water. Also driving in high altitudes (> 4-5000m) without turbo can be a problem with diesel. Diesel engines want to be driven. If you just commute a few km a day, drive around only with low speed or let your car sit and wait for the next trip, this is not good for the longevity of a diesel engine.
Waldemar Ishibashi he is talking about the Land cruiser 70 series. Only the new Land Cruiser prado and hilux are available in Germany but with DPF and ad blue 🤬🤬 we can only buy the Land Cruiser 70 Series with the petrol engine (imported from UAE i think)
I love the video. The breakdown and scenarios. Spot on. I have an 82 chevy with factory diesel that i almost converted to gas. After driving with that diesel engine i wouldve been a fool. I haul 6tons + logs twice weekly with my diesel, go mudding crawled some rocks and steep terrains use it for pulling my boats to lake. Without a doubt the diesel fit my lifestyle. And the fuel efficiency is unreal. I upgraded to 33 12.5 15 tires and get 27mpg on highway. It is a v8 diesel so the power comes different then the benchmark cummins. I have amazingly low rpm lugging abilities. Will deffinitely check out more of ur vids. And my truck is a daily driver + that ive owned 3 years now and have only changed water pump and fluids/filters on engine.
On maintenance costs, it's worth noting that it's usually a wash. The diesel parts that eventually need replacing may cost more, but they also typically last much longer than the wear parts on a petrol engine. You'll go through multiple sets of spark plugs and wires before having to replace diesel injectors.
Something else to mention regarding fuel economy: You brought up that diesels are better for long treks. This is true, but only when driving long distances with fairly consistent speed. For short distances, with a lot of stops or inconsistent speeds, diesel and petrol are about the same, with petrol being a bit more fuel efficient.
Excellent speaking voice . I thoroughly enjoyed this video . Believable information , no radical claims and leaves so much to the buyer to have to decide . Well done mate ! I am subscribing !
Petrol engines can last a long time way longer than 5 years (depending on how you treat and drive it) I have a petrol 89 hilux with 430000km on it and it’s absolutely perfect
He never said petrols last 5 years. 5 years for return of investment. e.g the same spec diesel car will cost more to purchase than the same spec petrol...
I agree, but it highly depends on the make, year, and model. Best example I know of, Jeep wrangler or cherokee, older models had the 4.0 straight six. You can literally get thousands upon thousands of miles and they don't die. The newer models have some other engine that is not as durable imo nor has the track record. Same with Fords 4.9L straight six, can't kill the damn things, everything else will go before the engine does, lol. But I will say some of the newer engines are pretty good, change the oil at 3k miles not 5k, perform preventive maintenance accordingly and it'll last a long time. Most gasoline engines if taken care off properly should easily last 250-300k before major work is needed.
@@sowslaying Guessing "Petrol" was actually Diesel in your comment. Canada gets pretty darn cold too... I've seen diesel freeze in the jerry can. At least with pump gas you can start a car in -20 no problem.
Well this was very informative and helped me make my decision. I live in the Middle East and it’s all about sand dunes so I’m going petrol for sure with my new off road car.
@18Dreaming let's goo sorry but your comment just doesn't make sense, there is no way a gasser would have better mpg since diesel has more BTU s, well i guess everyone around the world that has offroad vehicles and even swap diesels in them is wrong then, you should go to the news and explain your new discovery.
@18Dreaming let's goo If the rule applies to smaller diesels which are slightly heavier than petrol, and still they are more fuel efficient, why don't they apply to bigger trucks ? Something is wrong with your logic. You are probably comparing completely different trucks in size and age. Can't wait to see petrol air planes, tanks, boats, trains and other industrial equipment... since by your logic petrol is more fuel efficient. Also which engines last longer, with the least amount of wear ? You may be surprised by the answer. Good luck.
We always start fires with diesel. Why? because it burns longer and actually has a chance of lighting the wood (FYI we're in High Country Victoria generally wet and cold) unlike petrol.
I think Ronny nailed it. Diesel is a vehicle that proves its worth over the long term. It is certainly more efficient for work and towing duties, so a lot of commercial applications rely on it for that reason. Petroleum (gasoline for us in North America) is cheaper to buy and maintain (and cheaper to fuel in most parts of North America). It’s not nearly as efficient but it works well enough. And for a majority of 4x4 owners it makes more financial sense since they tend to jump between vehicles. After several years of owning a gasoline Toyota, I’ll look for a diesel for my next vehicle. The North American market has new and upcoming diesel options in all the major segments.
Diesel swap it! I will be swapping my tacoma in a year or two. There are many good options out there, especially a lot of older vw/audi tdis. Mercedes also has a couple good engines and even cummins. Of course some modern options from the jeep/ram 1500 I have heard to be quite good if you have to have something that meets emissions.
I'd love to have a diesel swapped Toyota, something like a 2.8l Cummins in an old Toyota LandCruiser or pickup. Unfortunately, emissions testing and regulations in my area restrict which vehicles can take diesel swaps....right now the 2.8l Cummins is certified to swap into 1999 and older vehicles.
I have a 2017 Chevy Colorado with the 2.8 duramax. I have 5.5" lift, 35" tires with 4.56 gears and a tune/delete. That thing HAULS, loaded or not loaded. Still getting 20mpg average.. uphill, towing, off road, loaded, unloaded, commute to work, all of it. Best decision. It has 18,500 miles on it and I've have had 0 issues.
All you have to do is look at car manufacturers these days, most are going back to petrol, petrol engines are becoming way more advanced with there fuel economy with cylinder shut off and like features, and here in WA diesel rarely has a "cheap day" where as petrol is always fluctuating. Plus I think the big thing everyone forgets is they all want power, and for example a td42 patrol with a 12mm pump and big boost will use almost the same as a modern stock petrol that has relatively the same power, but the cost it takes to get that power out of a diesel is ridiculous, petrol is on its way back and the way they build petrol 4wds is so much better now and water really isn't a problem, everyone has this old wives tale that petrol engines will die in water, that's long gone unless your in an old petrol with a distributor you don't really have anything to worry about, a diesel fuel shut off can be damaged in water just as easy. Good video as usual Ronny
yes,but out bush,petrol causes fires,they say..i cant go thru the simpson.with petrol.diesel now,is like lpg,false economy,.my bronco costs $40,to service,my f250 costs 140.there just not viable.an,.lsi,chev.or ls3.is economical with shit loads of power.why,these days,would you want diesel.its being slowly banned,because its carcenogenic,they say..my f250 is the mwm sprint engine,german.ive fitted a tdo6 turbo.04 is std,,its now 700nm,,,170 kw..uses 13 lt 100...big,comfortable,tows,pulls anything,goes anywhere.ive proven that.i love it.for 25k,why not...plus it has a 145 lt tank. 3" system std.&,i run 35",on all my f series,.cant beat dana & new process.shit proof.
Great video! In the states, there are some places where you can get petrol but not diesel. Also, clean diesel can be very hard to find in Mexico. For us, we’d have to own a used diesel van for 13 years to make it worth the additional cost compared to a similarly equipped gas van. Interesting stuff!
Hey Ronny, great videos. My wife and I love them. Regarding starting fires when I was growing up in the bush we always used 2/3 diesel and 1/3 petrol to start and burn off damp timber. Burns controllably and long and slow. Thought I would just let you know so you can try it.
iVlogBuzz they did it for 3 or 4 years but that’s also endurance racing where pit stops come into play if you can drive for twice as long between fuel stops your saving a couple minutes compared to petrol competitors each fuel stop there’s a reason diesels aren’t seen in shorter races
Spoke with a Finnish lad who to neither they're diesels have an under bonnet heater on a separate battery they run before turning over em over. As well as the additives to reduce gelling / waxing
They where running diesel engines but not diesel fuel. They burn a mix off alcohol and caster oil they dont let the public now this. Much more hp rpms and response.
There's no reason why diesel can't make power, traditionally people buy they for their low end torque, naturally it makes sense to pair the engine with a tiny turbocharger. They spool up early and help boost that low end torque figure, consequently restricting the engine up top. Look up om606 superturbo . Mercedes Benz diesels making 600+ hp at 7500rpm on unopened engines. (Just bolt ons)
Very informative video. I was stuck with the choice of diesel or petrol in a land cruiser. I had driven all 3 down the terrain i frequent. Only downside which I picked from your chanell was the water crossing issue but I eventually came down and bough a petrol which I wanted to run the enterprise for the next few years then get a diesel. The terrain is rough but not as rough as ive seen you drive through.
Well done mate very good comprehensive unbiased and balanced comparison, personally 90% of my off roading is on sand and dune driving so im one of the outnumbered petrol fans.
The 2UZ-FE engine is a very reliable engine for me it’s the best petrol engine toyota has ever created for the big SUV’s it’s available to 100 series cruiser.
I agree with you completely, that said, I’d like to add a bit to your mileage section. Diesel mileage is by far superior, in the past. With the addition of the DPF and now DEF(diesel exaust fluid) I have found that it effectively kills diesel mileage. But, weight doesn’t effect the mileage as much. Just my two cents.
Ronny, I have to take issue with some of your definition of flammable vs. combustible. The flash point is the temperature the liquid with turn into vapor making it able to ignite. The ignition temperature is when it will burn. The way you phrased it made it sound like petrol would burst into flames on a hot day.
Ronny Dahl diesel and petrol both doesn't explode. The both combust. It's a combustion Engine not a explosion engine. The flamespeed is far to slow for a explosion. Yeah it doesn't has to be a physics lesson but as a mecanic it's something i hate hearing. Other than that: Great videos man, good job :) greetings from Switzerland :D
@@sowiedunedheisisch yeah, bugs me too. Plus he stated diesel burns slower but emphasised its an uncontrollable explosion. No. Its a controlled expansion in both. Diesels are built heavier because they have greater compression ratios and thus produce far higher peak combustion pressure. Torque is proportional to pressure given the same piston diameter and stroke. Which is why they have more torque. The pinging has more to do with timing than anything else. You can get many diesels now that don't have the typical diesel knock of older engines. Diesel engines are built heavier as is the running gear for them because of the greater torque. Nothing whatsoever to do with an uncontrolled explosion.
I think this channel might be the greatest thing since sliced bread! ha I LOVE watching your videos!! I always look forward to these videos because they are no B.S. It is always a subject I care about and it is always very clear and precise. It's not some guy trying to sell me on this product or that! It is all very good clear information ANY Overlander likes to see. I am in America. Australia is so far ahead of us in overlanding that we desperately need ANY information your kind enough to share with us. I watch 4x4action EVERY chance I get. I love the trails they take and the ability of their rigs! Your videos are the ones I will shew away my girlfriend to finish.
As usual Ronny makes some of the best content on the tube. I would kill to have a diesel cruiser. Sucks that we don't have them in the states. I do love my JKU though.
LC gasoline engines have extremely good longevity. The 4.7 & 5.7 v8 engines will last you 300k miles. Diesel engines are heavier and less powerful, but more power at lower rpm though. There is no practical advantage to diesel outside slightly better off the line pulling power and higher efficiency. The added weight will negatively effect the vehicles performance and will wear down suspension and drive train components more. Since fuel costs are what they are in the US, diesel efficiency is not such a priority, and the cruisers modern 8 speed auto is extremely good an generating torque through its gear reductions. The limiting factor, as far as payload and towing, for the land cruiser is its chassis. So a diesel will not grant you more capacity, but maybe more confidence. Fact is, diesel takes more maintenance and the cost benefit of it in the US doesn't make it attractive. Outside light duty pickup trucks with the marketing ploys of heavy & super duty, diesel residue value would be hard pressed to recoup the initial cost + added financing and maintenance costs.
Thanks Ronny , another great vid .. You were the one that sold me on my Pajero after the review you did . 2006 LWB with bull bar , roof rack and all the other goodies I plan to put on.... Many thanks
I have a 97 gmc sierra. Runs perfect no extra noise nothing. Love it. Felt bad lifting it because it was supper nice with no dings so I kept all the oem parts so I can put it back to stock in 10 years or so when its crazy rair
My 94 jeep grand cheroke with the magnum 318 5.2 v8 runs great bought it for 1100 2years ago and ive even driven it 150miles at once nonstop the only thing i put on it was led headlights tuneup and matience on point of course and i abuse it i even offroad with it with small 31inch tires it camewith a a cheap lift it has and ive been offroading with the big jeeps and trucks for 8hours taking just small breaks to let my engine rest just like the new jeeps and trucks chugs gas but its suppose to
Affirm. 1982 Bronco, going on 39 years. Still mostly stock save for the shocks and a few performance parts. About a million and a quarter miles on her too.
Gasoline engines are more power dense due to their extreme rpm advantage. Much heavier diesel engines wear on your rig more. Diesel engines have greater longevity and efficiency. Their low end power really is nice for slow speed maneuvering. If you need lightweight and agility... then gasoline. If you need low speed power and efficiency... then diesel.
Torque is more important for 4x4..which is diesel have advantage. Diesel can generate torque at low RPM..as low as 1200 rpm. Which is gasoline engine cannot match that.
This is the best GENERAL INFO video about both kind of oil based engines I ever see... Snappy and short... Enough for the people to study more deeply about, and generate a basic idea on what to buy/invest for a 4X4... I love off roading but 90% on time I'm on roads :( ... Greetings from Costa Rica Ronny
because city teens and 20-somethings will buy them to compensate for their insecurities, lift them into the fucking sky, tune them to blow black smoke, and throw on rubber band mud tires with oversized wheels, then never leave the pavement or do real work with them. those people are the reason the EPA is getting stricter and stricter with their diesel emission standards.
Usually, I'll go petrol for daily driving or having a sports car. But since I moved to Europe, if you want an off road vehicle here, diesels are much better options. Better fuel economy, filling up the tank is cheaper than petrol, there's a lot of support of parts for maintenance and that extra torque is well useful, too. Also, it depends on the model. For example, Toyotas make bulletproof petrol engines that last forever, but I've heard their D-4Ds may have some issues. I would only choose Toyota if it's petrol. Otherwise, I'm thinking about getting a new Navara, Y61 Patrol or even a late 80s to mid 90s G Class, back when Mercs were solid built. All of them diesel, of course.
On the US interstates you can find diesel easily because of big rig traffic. While it's true because of demand not every fuel station has diesel , pretty much every town does. Even in 2008 when I drove from Clarksburg, Massachusetts to the San Francisco Bay Area, on mainly back roads trying to avoid the freeways, finding diesel wasn't even remotely difficult.
I had a '79 Mercedes 240 with 700,000 miles and while the fuel economy was still great (+40mpg!) Rich is correct, in some areas it is hard to find diesel... At night, when every service station is closed but one...and it is raining. One thing the video didn't mention is the increased jeopardy diesel drivers face if they run out and need to crack lines to purge air! (Again, ask me how I know lol)
So, what I'm getting from this channel is a) we need black steel wheels with mud tires 2)diesel motor (deliberately overfueling to make soot) d) sleeve tatt, neck beard and southern cross stickers for back window of rig. What else do I need? Light bar mounted on bullbar?
One thing you didnt touch on is resale value which is better? Say after 5 years of ownership or even 10 years. For me i own a 1999 TD42 Patrol with nearly 400000ks and its still worth around 20k but same model petrol vehicle is worth only half that. If you live in Australia Diesel just makes sence.
Depending on the details diesel can still be more expensive... Higher maintenance costs, more oil, more filters, more expensive filters, possibly def. Financing costs. Diesel can be a 5-10k dollar option. Which can add an extra 500-1k dollar over to course of a loan. Diesel engines depreciate, meaning they add 10k to the initial cost and return an additional 7k for resale... which is a loss. The overall depreciation percentage might be lower, but the higher cost can still mean that you lose more money on the car. So yes and no, some diesels save you money and some don't. Here is an interesting read. www.google.com/amp/s/www.forbes.com/sites/matthewdepaula/2012/08/27/clean-diesel-cars-and-trucks-that-will-save-you-money/amp/
Rolly B resale is higher, but you can lose more money on it still. I'll give you an extreme example. I buy a Land Cruiser for $100k. After 5 years 60k miles it's now worth $60k. At the same time, my coworker purchased a Ford mustang for $35k, and drove it the same miles and sold it for $15k at the same time I did. The LC only lost 40% value while the mustang lost 57%, but in the end the LC owner lost more money due to a higher initial cost to buy despite having a superior resale value. Diesel doesn't give that much higher of a resale percentage here in the states and the engine option averages $5k, so many models do lose more of your money in the long run. I posted an article earlier that outlined which models were more economical to get diesel.
Good factual points, but im guessing you guys have overlanding in mind. For short off road trails, the small Jimny/Samurai/Gypsy is ideal, can carry a few days of supplies anywhere you want where The larger diesels can struggle with its weight. The terrain is usually hilly and rocky where I live so I guess its situational at best.
Diesel for me!! Just need to seal the common rail sensors and computer in my case. Also a Turbo is awesome in a Diesel engine, so much more power. Great review Ronny!!
Hi Ronny, I was watching one of your vids on a 80 series. A question was asked "What is the first thing you would do to a stock standard vehicle?" The answer was legendary "Drive it". In my case no way I could afford a 10 00 diesel so got a trusty 1fz 80 series. So in regards to petrol or diesel is what ever get you out there is the better bet!
Jim Stepkoski Do you live in a small town or something there is a crap ton of diesel trucks in the US. The scout ih came with diesels so did the dodges with a Cummins motor, ford with the power stroke, chevy with the 6.4 and Duramax engines. Most if not all US Humvees have a GM 6.4 in them and you can pick a used Humvee up for under 10 grand.
Almost all of the ones you listed are full sized trucks which are not good for offroading unless you get a single cab long bed version that gets it's wheel base in the golden zone. The only modern contender is the colorado/canyon.
The example is used because the new standard size truck is a quad cab short bed.Probably 80% of the trucks on any new lot are a full size 4 door with a standard bed for an average owner to easily fit a family of 4 (minus their fleet vehicle selection). The extended cab is also much more top heavy due to the added weight of the cab. Seeing how there are no options I know of for a single cab short bed diesel (Maybe the dodge eco diesel but I am not sure), which would put it in the 120 inch range, the best option for an actual offroader that isn't too heavy for it's own good, leading to snapped parts everywhere and an increased risk of roll over, is the single cab long bed that has the diesel option. which puts it in the 130-140 range. Either way. This option would get it's butt kicked when put up against an equally built solid axle toyota or wranger due to their size, weight and agility (due to being in the optimal 120 inch wheel base zone) benefits. Again, the only diesel option for an offroader right now without major modification is the colorado/canyon.
Hi Ronny; I think you hit the nail on the head with this one especially in Australia. If your up for just running around town with the occasional weekend off road trip petrol's fine but if your serious about 4 wheel driving in the remote outback then diesel wins out every time.Good comparison though. I'd be interested to find out which expands more as I see a lot of trucks with very bloated red plastic cans on their roofs in the Aussie heat.Regards from bigezi
I wish there were more diesel options in the US. Having said that, longevity of petrol trucks/engines is way more than 5 years if you are moderately good at maintenance. I have a 2004 4Runner (Hilux Surf in AUS) that runs as good as the day it was made and it's been wheeled quite a bit. The Toyota 2UZ-FE petrol V8 is an amazing engine with quite a bit of torque. Would I rather have an Australian spec diesel Hilux? Sure, but i'm not going to lose any sleep over it. I do wish you would put the steering wheel in the right place though :) Great vids Ronny!
A V8 Classic Range Rover on an Auto box is a lovely vehicle to drive. A lot of fun on the road with an amazing burble. The torque converter eliminates any torque advantage the diesels have, and as horsepower = work done it will always win, and that’s what’s fun about a petrol. It’s a marmite thing, and very divisive. Great video Ronny.
All the modern petrol coil packs are sealed and up high and water crossing haven't been an issue in 10 years. Diesels are now way to unreliable with there DPF and ERG systems and to get anywhere near the power of an equivalent petrol you have to spend a fortune and make it less reliable again. As for life span of the engines think of it this way, one is naturally aspirated and there other has 25psi boost before you modify it to try catch up to petrol power. The biggest problem with this debate is not enough people have owned both engines and only comment from one side.
the issue is that modern diesel engines have the same electronic controls as gas engines, therefore the biggest advantages are now gone, plus at least in USA the engines now have DEF, DPF, ERG, and DOC, so they have the same exhaust heat as a gas engine, the same fuel economy, are more complex, and are FAR more expensive, whereas on gasoline all you have is EGR and catalytic reduction for emissions controls, plus most vehicles wont care too much if you remove the cats, and in some cases CEL wont even come on properly, thus eliminating the field fire risk, Modern US diesels will throw an absolute fit until you reprogram the computer. In the USA there is also the fact that diesel is less available than gas and is taxed higher in many cases, for example where I live gas is $2.47 per gallon, diesel is $3.97 per gallon and for the most part its taxes that make up the price difference, also in the US market usually gasoline engines are a far higher displacement than in eastern markets, thus with proper gearing they will crawl anywhere in first gear, in my case my unmodified BBF v8 will pull the truck hard enough to break 35-12.50s loose on gravel/mud/sand or on super steep inclines in 1st high at only 400 RPM with the idle screw turned in, even with my stock 3.54:1 gears
@@ghost-jesus GPF (Gasoline Particular Filter) are being installed in VW and Subaru. Possibly more, these I heard about so far. Soon second hand vehicles will have no value due to maintenance costs. I often use J.Gr Cherokee with 3.5l V6 in Japanese mountains. It never sees over 3k revs and doesn`t sound like a farm vehicle. The only annoying thing is my bottom is too small for the seat. The owner is sumo guy so he is fine ;)
ghost jesus in NZ Diesel is a lot cheaper than petrol, even when we add road tax for the diesel fuel it still end up being cheaper. My vehicle can get 700km per tank being diesel where the same vehicle as mine in petrol will get 450-500km per tank with the tank being the same size. With that I’m getting more torque and close to if not the same kw. Diesel is a win for me.
@@Palpac in USA the diesel emissions equipment is getting the diesels down to the same fuel economy as a gas engine, plus the DEF consumption on the new ones is insane compared to a few years ago, plus modern diesels won't even burn cheap distillate, not to mention the older diesels are completely gutless, I can get a 7.3 that makes 200 HP@ 3600 385 lb ft @2200, requires a turbo for more power, or I can continue with my 7.5 gasser with 350 HP @3800 and 545 lb-ft 2200 and can be built further without forced induction
ghost jesus also from New Zealand, my 2.5l 4 cylinder Navara dual cab came from the factory putting out close to 500nm before being chipped. I don’t run crazy boost or anything silly like that but she’lllight up all 4 on gravel, sand etc with very little right boot. Chuck the lockers on and I can idle up rock steps on even the snow farm testing grounds near Wanaka where Audi, Benz etc test their G wagons and Quattro
Was thinking more of offroading vehicles with diesels of which the ZR2 would be a decent option. I'm gonna see about the 3.0 Jeep diesel and decide on it.
Another consideration is 'where' are you going? Why? Fuel availability. Now, most people would autoresponse; diesel! Yes, diesel HGV's are very common. But wait a sec, what is the main form of motor transportation in Africa and Asia? The answer is small petrol motorbikes. Petrol for them is available everywhere. Not necessarily so for lorries. I have had far more trouble getting diesel in remote places than petrol. That is a major difference between 'off-roading' and 'overlanding'. Related to that, any bush mechanic can help you with a normal petrol engine. A high-pressure diesel pump? Good luck with that! Just something to think about. Cheers!
good comparison, I believe the main reason a diesel engine is heavier is on a petrol/gasoline engine compression is around 8 to 1. but on diesel at least 30 to 1 ( this is how the air gets hot enough to ignite the fuel ) .. so everything beefed up to cope with at least 4 times more compression
Most modern normally aspirated gasoline engines are around 9:1 compression ratio. Diesels are typically around 20:1. The higher compression ratio and less controlled combustion timing are why diesels have to be so much stronger and therefore heavier.
Mister510 close. Modern gas engines are over 10:1 for turbo applications and around 13:1 naturally aspirated now. Compression ignition engines have also come down to reduce NOx emissions, so 16:1 isn't uncommon.
obviously miss informed …. Eg 200 series cruiser engines: petrol 10.2:1vs diesel 16.8:1, !!! a lot of modern small Ltr ULP engine are heading toward 12:1 now days, technology is a wonderfull thing lol
I’ve had a ‘97 Ford Powerstroke for 16 years and 355,000 miles. It’s still a beast. I have bought and sold four or five gas rigs over that time and all are gone for one reason or another, mostly due to poor reliability and fuel economy. The Stroker never lets me down.
Hey guys. I'm not an expert in any area by any means but I don't agree with the statement at the 5:28 mark regarding that a gasoline powered engine revs higher because it's more controlled. As far as I know, it revs higher because the distance that the piston has to travel in the cylinder is smaller. Diesel engine pistons need to have a little bit more of travel in order for them to compress enough air so it can reach the correct temperature. Therefore longer travel, less rpm. If I'm mistaking, please do tell me and I apologise if this comment isn't theme related. Cheers.
Diesel engine are built stronger because of higher torque levels, massive compression ratio's with huge compression ignition values and also for long life reliability. Common Rail Diesel is not "uncontrollable" ignition, it is precisely injected just like a petrol engine. The older diesels engine are also not "uncontrollable" they just ignite the fuel at a less precise moment. Petrol 4.7L Landcruiser engines regularly go over half a million KMS. Diesel at idle burns less because it is diesel for 1 (More joules of energy per litre) and because it is not stoichiometrically locked with a certain Air Fuel Ratio. A diesel (non common rail) also has no throttle plate causing pumping losses and this increases economy over Petrol. Just my 2 cents worth.
Totally agree with your comments and your videos are clear, concise and informative. Well done as we need more people like you out there to educate more people. Love your cruiser by the way.
I have a 21 year old 4x4 Rodeo 2.6 petrol that is still near original, still going strong. It also comes down to how you treat and maintain your vehicle.

I dunno about the 5 year thing Ronny. Consider the Toyota 1GR-FE in the FJ's and Prado's is bulletproof, vs the 1VD-FTE which has had plenty of issues since release.
Do you not understand generalities? What you are doing is anecdotal. In general, a diesel should go 300k miles or more. Most gas engines only go 200k. Can a gas engine go more? yes. Perfect examples are taxi cabs. They go over 500k with a gas engine. But at the same time, there are semi trucks that go over 1 million miles or more. The 5 year figure is also a vehicle turn over rate. Not life span. It's pretty much the average a person keeps a vehicle before buying a new one.
JP Onefourseven Exactly why i have the 1HZ toyota 6 cyl 4.2 diesel. None of that crap, old school indirect injection, and no computers or electronics. A real diesel 🙂
@@zososldier I don't understand. Maybe you can help. If 5 years is the average keep time of a vehicle would that not be vehicle's in general? I think he was referring to hard wheeling life span. Of which I don't agree with. My 87 xj 2.8l v6 gasser. At 450k with nothing more than a carb rebuild is not uncommon in the states. I think location plays a huge roll in what is and isn't valuable.
My little 4cyl Yota does fairly well off road, specially with the lower gear set. Down hill with a manual in low range I barley have to us the brakes. But at 350k on 95% stock components I’ve been on the fence about which engine conversion I’m gonna do. I can build a V8 with good low to mid range torque, but diesels have better torque to start with. Pros and cons of both, bottom line figure out what you want to do with the vehicle like building an engine. Figure that out and then do your pros and cons of the engine, once you got that build your rig, everything else will follow. Great vids mate, looking forward to future updates.
mybe you should buy a front diff so you dont get stuck or roll over..never ever buy a vehicle with ifs,there weak,no travel,high maintenance.,it might break 1600 ks away from a cv garage.he he ,get a jeep front diff with uni.s,d44,stronger than any ifs.cheap & basic. cant beat american.
Got a 2013 Pajero NW a few months ago and decided on the diesel mostly for the fuel economy over the V6 petrol, hope to own it for a long time, I don't tend to change cars often, my first and only new car lasted me over 20 years. Found out the hard way with the service costs, and some other work I've had done to fix things neglected by the last owner, oh got a catch can installed at the first service after they cleaned the intake, $2500 total for a service and the catch can.
Can definitely relate to more cost for parts. $4200 for a reco injector pump for a ZD30. Was thinking of converting to a turbo petrol, but after watching this.... looking at sticking to a diesel, might step up to a TD42 in the Patrol.
A bit rough on some of the explanations, but I think you hit the nail on the head. There are ways, though, to mitigate many of the petrol deficiencies (auxiliary reductions, stroker mods, waterproofing electricals), but they require serious investment and modifications and are better left for people who are capable of doing and maintaining those mods themselves.
Yes but all those mods combined still cost less than a set of diesel injectors that last 25% as long as petrol ones.. that's not to mention the $3,500 for a diesel fuel pump
I used to have a diesel 4x4 I nearly cried when I sold it I was so happy. Went to a petrol and never regretted it. Fuck the increased fuel costs, fuel is cheap. Fuel pump rebuilds etc on diesels are not. Modern petrols are fairly good on the juice even places like Fraser island now I average about 20l/100km.
If your having to do multiple fuel pump rebuilds/replacements, you're not doing maintenance or not adjusting your maintenance schedule for the shitty fuel you're buying. 275k/~440km and I've never had any issues with any fuel system components
Modern diesels are even worse. There have been many horror stories of them shutting down after being filled with poor quality diesel (high in sulphur) which is what you find in developing areas in africa and latin america and asia. There is one guy on youtube who drove across america and africa in a petrol wrangler for this very reason.
Unless buying GM there's no diesel options in North America at least not for smaller trucks. Unless buying a 3/4 ton or bigger. So we don't really have much of a choice but to have gas, all Toyota, Jeep, Ford are petrol. I've owned vw diesels though and by far wish I could have a diesel Toyota. The torque is the best. My only issue with diesel is in the cold climates here in Canada it can be a pain in the winter.
That has more to do with the shitty emission laws in the US. Diesel is extremely restricted in how much particulate matter you can put into the air, gas isn't. Because of that it isn't worth it for manufacturers to try and produce smaller diesel engines as it is easier, cheaper, and less restrictive to built larger gas engines. Once you enter the 3/4+ arena it is definitely diesel is king, but for 1/2 ton and under trucks it is a gas world, especially with turbos.
Bnadit yep, and it's because of that I find it idiotic when people say they think Toyota will bring a diesel 4runner or Tacoma here. We'll see hybrid before diesel in North America
That is still a $9,000 engine though. If I could have it my way I'd put it in as the power plant in my off-road build, but when it costs more for the engine than it does for the truck and everything else it is very hard to justify.
Bnadit the crate engine costs more, but Diesel engines inherently cost more (as Ronny noted) plus you get a complete installation kit with that cummins crate.
the pros and cons are for very different scenarios. water crossings, long grass... never even thought of those, cause i aint wanna get those sensors wet
I drove only petrol cars for almost 25 years. I hated diesel, never owned a diesel car or truck. Recently, I purchased a diesel SUV. I fuking love it!!! DIESEL every day, all day!!!
i have a 1985 petrol and a 1986 turbo diesel 4runner and about the only downside i have come up with so far is that the diesel isn't as good on the highway, only just slightly better off road though, petrol one is much better at coping with the wind drag from roof top tent, the diesel struggled to get to 100 petrol will sit on 120 no prob, good vid keep em coming
In my short 5 years with the Army, the smell I'll always remember is the start of a shit ton of vehicles on a cold morning. That, and always having the smell of diesel on all my shit and hands haha.
I drive a 4L v8 Land Rover Discovery 2 on petrol..plenty of torque with the autobox on low range and also engine breaking is good in low range 1st gear.. and it sounds awesome.
Having had both I would now have nothing but diesel in a 4x4. Engines last longer if you look after them, they are easier to maintain yourself even if parts cost more. They are better at producing low down power and my biggest criteria, they don't overheat as much as petrol engines. Petrol engines slogging through sand up north overheat like crazy. I don't care about fun on sand, i just want to get through it to my favourite fishing spot....oh and if you really need another reason to go diesel, when the oil wells run dry, diesels will still run on fuel produced by plant crops.
Great Topic!!!! Plenty of people so stuck in their old ways, modern petrols are pretty amazing. I have a diesel, store diesel in my vehicle, no probs, but i'm not against Petrol
Why do you say that a gasoline/petrol engine will only last 5 years? I have a vehicle on its original engine with 300,000 miles/482803 km (who knows how many running hours) that is 23 years old and still running strong. Transmission could use some love if I find time for it...
acephantom903 he's not saying they'll only last 5 years he's saying its probably not worth keeping petrols that long but as u say ur old rig has got some Ks on it and fine but I don't think any modern design petrol will last that long
ko _danjy I'm running a petrol with 176k miles on it. It's from 2002. Is that modern? Idk but I believe most off road worthy vehicles will have an engine that will last to 200k. But he is right that most people are swapping around 5 years. Would buying a diesel change that?
309,000 miles (497,287 km) on my 2001 xterra and like acephantom903 the tranny on the old xterra will need some work and or replacement soon. Diesel motors can go 3 times the distance for milage. One million miles on a diesel motor is not unheard of.
After the 5 year period the cost of owning a petrol starts to cost more then a diesel when you take in the cost of buying, maintaining and running. so buying a diesel may cost more outright but you compare costs over 10, 15, 20 years and the diesel is more cost effective in the long term generally speaking
Regarding water crossing I believe the most vulnerable part of the engine is the ECU and where it's located. If is somewhere that can get wet easily eg floor or engine bay that's game over. Modern coil pack petrols can be great in water. I've had mine running fully submerged for 3 minutes and never missed a beat. Not saying they are all like this but things have changes a long way since the old dizzy petrols VS mechanically injected diesels which are the main sourse for the diesels arguement.
He makes a great point about water in a diesel engine. In high school I attended a diesel mechanics course. We had a piston that had come out of a Cummins diesel from an 18 wheeler that had water ingestion damage. The compression ratio is so high in diesel engines that drops of water become the equivalent of a steel ball bearing banging up and down in the cylinder. The top of that piston looked like it was beat hard with a tiny ball peen hammer. Literally hundreds of little dents. Amazing.

Couldn't agree more about the low range crawling. Petrol does require alot more clutch work to do the same crawling. But a set of reduction gears changes everything. I'm able to crawl alot better now than most other 4wd's and the low range gears are still usable for mud and boggy sand. Would hate a low revving diesel with the same ratios.
Petrol also has the panic button if you get worried about getting stuck you almost always have 2000-4000rpm more to rev out haha.
Water is far less a problem with petrols as it used to be. I would even say it's on par comparing two modern vehicles. Coil packs tend go hold out the water well.
Diesel everyday mate! 👍
In the flat lands
Hell yeah
There is another point of consideration that was not raised in this video. And that is, recovery from roll-over. When doing rock-crawling, jumping sand dunes, climbing hills, that sort of thing. If you roll your off-road vehicle upside down, and then roll it back upside up, while the engine was inverted, oil from the oil pan seeped past the piston rings and have filled the cylinders with oil. With a gasoline (or petrol, depending on the terminology used in your country), you can just remove the spark plugs, crank the engine a few revolutions, replace the spark plugs, and be on your way. With a diesel, removing the glow plugs (if equipped), or fuel injectors are more difficult. I have both Gasoline and Diesel vehicles, one of my diesel trucks doesn't even have glow plugs, and the injectors are difficult to get to. If the cylinders filled with oil, I would have to either come back with more tools, or have it towed. The gasoline, with the spark plugs, much easier.
John Davis that’s a very good point....!
John Davis I would just crank it a couple times until it flushed out and be on my way
Here in the States, we don't have a lot of smaller diesels like the rest of the world (though they are starting to catch on as of late), so most diesels are the big, towing type. They have massive, heavy blocks that weigh a ton and severely hamper offroad performance. They are not well balanced, they tend to sink into mud, sand, and snow much worse than a gasoline engine vehicle, and they wear out tires faster. The most serious offroad vehicles here (both stock and custom built) are gasoline powered.
Petrol for sand dunes and racing! Diesel for towing and work.
very true,i sit in sand spinning wheels while the diesels stall,nothing has stopped the bronco.
I recon if you live in WA go Petrol 👍
@@ericcartman8694 very dumb
Petrol for higher altitudes too.
So... is 4WDing sand dunes or work?
I have owned a 62 series 3f '86 on gas/petrol on 33" muddies for 20 years now, done around 600k still going well, no rebuild, no oil use, not quick but super reliable and torque, gas keeps it cheap. Many Deisels of the time have had very expensive rebuilds done at 300k. I'm not complaining.
I got a 80series diesel that just clocked 800k and hasn’t had any major problems
To be fair, Toyota designed all engine variations for both the 60 and 80 series to be 1,000,000 km engines before a major rebuild. So apples with apples on this argument 🤷🏼 we can all agree that the difference between petrol and diesel reliability is tiny in comparison with the reliability difference between Toyota and Nissan 😅
You either invest in diesel and hope to get the increased cost of initial purchase and increased cost of fuel and maintenance back through reduced fuel consumption or you by a petrol for significantly less initial cost and less maintenance cost and less fuel cost(per litre) at the pump and hope you don't eliminate the savings through greater fuel consumption. Modern day petrol engines are so efficient that it makes the choice harder than it was say 10 years ago.
I have an easier way to differentiate them: If you want to buy a van or a full size SUV, no matter you drive off-road or not, diesel will win on economy. If not, petrol will win.
@@wangjialei1985 Economy - in what sense? Less fuel for diesel, but if something goes wrong with new diesels DPF, EGRs, dual mass, AdBlue etc the savings disappear.
Waldemar Ishibashi Diesel engines are more difficult to maintain, that's true. So you can't use other replacements (some new types of diesel didn't pass the long-term test) before they are proved to be safe.

Thank you.
Hi Ronnie
Great video. Just a thought that you could have included service regularity. Diesel certainly require more regular oil changes to ensure longevity.
And the reason for diesels being built stronger is mainly because of the higher compression ratio.
Not only does the DPF - DPD get hotter but the gas coming from the exhaust is extremely hot too. I worked for a well known Japanese brand of truck for 10 years and when they introduced the DPD in 2008 we brought up the problem of exhaust temps while regenerating. We were told it wouldn’t be a problem. We tested a truck during a break in our training and got it to do a manual regeneration. We lit a cigarette by holding at the end of the exhaust. No problem?
We were then instructed to advise customers not to park the vehicle next to anything flammable with the engine running. Rural Fire Service stopped buying the trucks saying that their job is to put out fires not to start them.
Thanks again for the videos
wait... water crossings = long grass? :P
HAHA
Oppps
I dont know how it is in Australia,but in Germany we have a lot of grass around our rivers.So when you fight through a river you encounter high grass.Maybe thats how he came to that point XD
Also, just thought of the point about exhaust. Diesel engines run cooler on the way out of the engine, and in a gasoline engine, the components can get VERY hot. When attempting a deep water crossing in a petrol/gas engine, you sometimes need to shut the engine off to let it cool. Crossing deep water that is cold like near a mountain river/creek, can break exhaust pipes and other components because of the large change in temperature.

Nice video Ronny....!
Well done being brave and taking on this subject. So many people will have issue with your science. I don't, as I know what you are trying to get across.
Great video again with lots of good points, mate!
But from a foreign (German) subscribers point of view, you missed some important issues, especially regarding modern diesels:
You will mostly have to use ad-blue (DEF) and all the pain-in-the-ass issues with DPF to meet the modern exhaust standards of diesel engines.
From now on, you can not even register a diesel Landcruiser in Germany anymore, because the motor does not comply with the latest regulations. Only petrol powered LandCruisers models are imported as new.
And with older diesels you are not even allowed to enter some European cities anymore.
The German company Extrem Fahrzeuge even sells an electric bush taxi version. Unfortunately, due to the low range (nowadays) this is interesting just for mining company's etc. but not for long distance travels. Hope batteries will improve soon so it will be THE kind of drive ruling out petrol and diesel....
Another issue for overlanders:
Diesel is not always so easily available around the world, e.g. not in Usbekistan, difficult in Iran, or even not everywhere in the US....
Additionally, the diesel quality (sulphur & water content...) can be very bad in some areas and you may wreck your engine.
If you are unlucky and get the diesel pest into your whole distribution system, you'll have a big hole in your pocket. This may even happen in Europe due to the bio diesel with its high content of water.
Also driving in high altitudes (> 4-5000m) without turbo can be a problem with diesel.
Diesel engines want to be driven. If you just commute a few km a day, drive around only with low speed or let your car sit and wait for the next trip, this is not good for the longevity of a diesel engine.
Why is the Land Cruiser L150 diesel 2.8l still available on German Toyota website? 27/04

I am the 5th owner of 1980 Daihatsu Taft F20 1.6cc petrol engine, it still running well.. I love it..
I love the video. The breakdown and scenarios. Spot on. I have an 82 chevy with factory diesel that i almost converted to gas. After driving with that diesel engine i wouldve been a fool. I haul 6tons + logs twice weekly with my diesel, go mudding crawled some rocks and steep terrains use it for pulling my boats to lake. Without a doubt the diesel fit my lifestyle. And the fuel efficiency is unreal. I upgraded to 33 12.5 15 tires and get 27mpg on highway. It is a v8 diesel so the power comes different then the benchmark cummins. I have amazingly low rpm lugging abilities. Will deffinitely check out more of ur vids. And my truck is a daily driver + that ive owned 3 years now and have only changed water pump and fluids/filters on engine.
I'm getting 23mpg on my 1hd fte 79 with the vehicle being 3.7 tonne on 35s it's pretty nice especially with current prices
On maintenance costs, it's worth noting that it's usually a wash. The diesel parts that eventually need replacing may cost more, but they also typically last much longer than the wear parts on a petrol engine. You'll go through multiple sets of spark plugs and wires before having to replace diesel injectors.
Something else to mention regarding fuel economy:
You brought up that diesels are better for long treks. This is true, but only when driving long distances with fairly consistent speed. For short distances, with a lot of stops or inconsistent speeds, diesel and petrol are about the same, with petrol being a bit more fuel efficient.
Excellent speaking voice . I thoroughly enjoyed this video . Believable information , no radical claims and leaves so much to the buyer to have to decide . Well done mate ! I am subscribing !
Petrol engines can last a long time way longer than 5 years (depending on how you treat and drive it) I have a petrol 89 hilux with 430000km on it and it’s absolutely perfect
Roy Smith I have thr same 89 hilux truck 22R Roy. I'm considering putting a 4500 4runner diesel engine since I got one and a big turbo.
He never said petrols last 5 years. 5 years for return of investment. e.g the same spec diesel car will cost more to purchase than the same spec petrol...
Roy Smith I have a 1990 Toyota 4x4 and love it.
I agree, but it highly depends on the make, year, and model. Best example I know of, Jeep wrangler or cherokee, older models had the 4.0 straight six. You can literally get thousands upon thousands of miles and they don't die. The newer models have some other engine that is not as durable imo nor has the track record. Same with Fords 4.9L straight six, can't kill the damn things, everything else will go before the engine does, lol. But I will say some of the newer engines are pretty good, change the oil at 3k miles not 5k, perform preventive maintenance accordingly and it'll last a long time. Most gasoline engines if taken care off properly should easily last 250-300k before major work is needed.

That's partly because they are a 35 year old engine. New diesels perform much better while using less fuel, modify them and they become weapons.

@18Dreaming let's goo sorry but your comment just doesn't make sense, there is no way a gasser would have better mpg since diesel has more BTU s, well i guess everyone around the world that has offroad vehicles and even swap diesels in them is wrong then, you should go to the news and explain your new discovery.
@18Dreaming let's goo If the rule applies to smaller diesels which are slightly heavier than petrol, and still they are more fuel efficient, why don't they apply to bigger trucks ? Something is wrong with your logic. You are probably comparing completely different trucks in size and age. Can't wait to see petrol air planes, tanks, boats, trains and other industrial equipment... since by your logic petrol is more fuel efficient. Also which engines last longer, with the least amount of wear ? You may be surprised by the answer. Good luck.
We always start fires with diesel. Why? because it burns longer and actually has a chance of lighting the wood (FYI we're in High Country Victoria generally wet and cold) unlike petrol.

I think Ronny nailed it.
Diesel is a vehicle that proves its worth over the long term. It is certainly more efficient for work and towing duties, so a lot of commercial applications rely on it for that reason.
Petroleum (gasoline for us in North America) is cheaper to buy and maintain (and cheaper to fuel in most parts of North America). It’s not nearly as efficient but it works well enough. And for a majority of 4x4 owners it makes more financial sense since they tend to jump between vehicles.
After several years of owning a gasoline Toyota, I’ll look for a diesel for my next vehicle. The North American market has new and upcoming diesel options in all the major segments.
Diesel swap it! I will be swapping my tacoma in a year or two. There are many good options out there, especially a lot of older vw/audi tdis. Mercedes also has a couple good engines and even cummins. Of course some modern options from the jeep/ram 1500 I have heard to be quite good if you have to have something that meets emissions.
I'd love to have a diesel swapped Toyota, something like a 2.8l Cummins in an old Toyota LandCruiser or pickup. Unfortunately, emissions testing and regulations in my area restrict which vehicles can take diesel swaps....right now the 2.8l Cummins is certified to swap into 1999 and older vehicles.
I have a 2017 Chevy Colorado with the 2.8 duramax. I have 5.5" lift, 35" tires with 4.56 gears and a tune/delete. That thing HAULS, loaded or not loaded. Still getting 20mpg average.. uphill, towing, off road, loaded, unloaded, commute to work, all of it. Best decision. It has 18,500 miles on it and I've have had 0 issues.
All you have to do is look at car manufacturers these days, most are going back to petrol, petrol engines are becoming way more advanced with there fuel economy with cylinder shut off and like features, and here in WA diesel rarely has a "cheap day" where as petrol is always fluctuating. Plus I think the big thing everyone forgets is they all want power, and for example a td42 patrol with a 12mm pump and big boost will use almost the same as a modern stock petrol that has relatively the same power, but the cost it takes to get that power out of a diesel is ridiculous, petrol is on its way back and the way they build petrol 4wds is so much better now and water really isn't a problem, everyone has this old wives tale that petrol engines will die in water, that's long gone unless your in an old petrol with a distributor you don't really have anything to worry about, a diesel fuel shut off can be damaged in water just as easy. Good video as usual Ronny

Great video! In the states, there are some places where you can get petrol but not diesel. Also, clean diesel can be very hard to find in Mexico. For us, we’d have to own a used diesel van for 13 years to make it worth the additional cost compared to a similarly equipped gas van. Interesting stuff!
Hey Ronny, great videos. My wife and I love them. Regarding starting fires when I was growing up in the bush we always used 2/3 diesel and 1/3 petrol to start and burn off damp timber. Burns controllably and long and slow. Thought I would just let you know so you can try it.
Yeah one of my Scout Masters growing up did this for us on a camping trip that was very very wet and cold.
Hello! I'm from Brazil and this is the best comparative between Diesel and Petrol I had see.
Great videoRonny. On a side note, I seem to recall Audi won LeMans 24hr race in a diesel.
iVlogBuzz they did it for 3 or 4 years but that’s also endurance racing where pit stops come into play if you can drive for twice as long between fuel stops your saving a couple minutes compared to petrol competitors each fuel stop there’s a reason diesels aren’t seen in shorter races
Spoke with a Finnish lad who to neither they're diesels have an under bonnet heater on a separate battery they run before turning over em over.
As well as the additives to reduce gelling / waxing
They where running diesel engines but not diesel fuel. They burn a mix off alcohol and caster oil they dont let the public now this. Much more hp rpms and response.
There's no reason why diesel can't make power, traditionally people buy they for their low end torque, naturally it makes sense to pair the engine with a tiny turbocharger. They spool up early and help boost that low end torque figure, consequently restricting the engine up top.
Look up om606 superturbo . Mercedes Benz diesels making 600+ hp at 7500rpm on unopened engines. (Just bolt ons)
@@bayls8422 you off your meds?
Great video - I have Petrol running now for eight years doing occasional off roading and no problems.
Very informative video. I was stuck with the choice of diesel or petrol in a land cruiser. I had driven all 3 down the terrain i frequent. Only downside which I picked from your chanell was the water crossing issue but I eventually came down and bough a petrol which I wanted to run the enterprise for the next few years then get a diesel. The terrain is rough but not as rough as ive seen you drive through.
Well done mate very good comprehensive unbiased and balanced comparison, personally 90% of my off roading is on sand and dune driving so im one of the outnumbered petrol fans.
The 2UZ-FE engine is a very reliable engine for me it’s the best petrol engine toyota has ever created for the big SUV’s it’s available to 100 series cruiser.
I agree with you completely, that said, I’d like to add a bit to your mileage section. Diesel mileage is by far superior, in the past. With the addition of the DPF and now DEF(diesel exaust fluid) I have found that it effectively kills diesel mileage. But, weight doesn’t effect the mileage as much. Just my two cents.
Ronny, I have to take issue with some of your definition of flammable vs. combustible. The flash point is the temperature the liquid with turn into vapor making it able to ignite. The ignition temperature is when it will burn. The way you phrased it made it sound like petrol would burst into flames on a hot day.
I think most people will understand that it needs a spark or fire source. I try to get these short and snappy it’s not a science lesson.
😂
Thanks for clearing that up guys. I live not far from a petrol station and was considering selling my house because its been over 40 degrees here.
Ronny Dahl diesel and petrol both doesn't explode. The both combust. It's a combustion Engine not a explosion engine. The flamespeed is far to slow for a explosion. Yeah it doesn't has to be a physics lesson but as a mecanic it's something i hate hearing. Other than that: Great videos man, good job :) greetings from Switzerland :D
@@sowiedunedheisisch yeah, bugs me too. Plus he stated diesel burns slower but emphasised its an uncontrollable explosion. No. Its a controlled expansion in both.
Diesels are built heavier because they have greater compression ratios and thus produce far higher peak combustion pressure. Torque is proportional to pressure given the same piston diameter and stroke. Which is why they have more torque.
The pinging has more to do with timing than anything else. You can get many diesels now that don't have the typical diesel knock of older engines.
Diesel engines are built heavier as is the running gear for them because of the greater torque. Nothing whatsoever to do with an uncontrolled explosion.
Best explanation on 4 stroke cycle. Simple and straight to the point. Very informative. Should watch by 4WD owner or owner to be.
Ronny my 90 series is comi g up on her 500k now mate cant see me going diesel any time soon . Great video as usual
I think this channel might be the greatest thing since sliced bread! ha I LOVE watching your videos!! I always look forward to these videos because they are no B.S. It is always a subject I care about and it is always very clear and precise. It's not some guy trying to sell me on this product or that! It is all very good clear information ANY Overlander likes to see. I am in America. Australia is so far ahead of us in overlanding that we desperately need ANY information your kind enough to share with us. I watch 4x4action EVERY chance I get. I love the trails they take and the ability of their rigs! Your videos are the ones I will shew away my girlfriend to finish.
As usual Ronny makes some of the best content on the tube. I would kill to have a diesel cruiser. Sucks that we don't have them in the states. I do love my JKU though.
Same, still waiting for my JK though😂
Would love to put a 2.8 cummins in my Xterra. Oddly enough they came with 2.8L diesels in South America.
NorCal Explorer Cummins would be a good choice
LC gasoline engines have extremely good longevity. The 4.7 & 5.7 v8 engines will last you 300k miles. Diesel engines are heavier and less powerful, but more power at lower rpm though.
There is no practical advantage to diesel outside slightly better off the line pulling power and higher efficiency. The added weight will negatively effect the vehicles performance and will wear down suspension and drive train components more.
Since fuel costs are what they are in the US, diesel efficiency is not such a priority, and the cruisers modern 8 speed auto is extremely good an generating torque through its gear reductions.
The limiting factor, as far as payload and towing, for the land cruiser is its chassis. So a diesel will not grant you more capacity, but maybe more confidence.
Fact is, diesel takes more maintenance and the cost benefit of it in the US doesn't make it attractive. Outside light duty pickup trucks with the marketing ploys of heavy & super duty, diesel residue value would be hard pressed to recoup the initial cost + added financing and maintenance costs.
HDJ81 Land Cruisers are becoming more abundant now. I picked one up 2 years ago. Totally love it!
Thanks Ronny , another great vid .. You were the one that sold me on my Pajero after the review you did . 2006 LWB with bull bar , roof rack and all the other goodies I plan to put on.... Many thanks
I agree with you. BUT! Gas engines last longer then 5years I have had some Toyota’s for 13years so I don’t agree with the age
I have a 97 gmc sierra. Runs perfect no extra noise nothing. Love it. Felt bad lifting it because it was supper nice with no dings so I kept all the oem parts so I can put it back to stock in 10 years or so when its crazy rair
He's not saying petrol will last only 5 yea. He's saying that it's not worth to buy diesel if you replace your vehicle often

I'll stick with my diesel thanks Ronny. Also love the background for this video
Gasoline engines are more power dense due to their extreme rpm advantage.
Much heavier diesel engines wear on your rig more.
Diesel engines have greater longevity and efficiency. Their low end power really is nice for slow speed maneuvering.
If you need lightweight and agility... then gasoline. If you need low speed power and efficiency... then diesel.
Torque is more important for 4x4..which is diesel have advantage.
Diesel can generate torque at low RPM..as low as 1200 rpm. Which is gasoline engine cannot match that.

DIESEL. WHY CAN'T WE GET YOUR DIESELS IN THE USA. GAAAA
Cause Aus is greater
Wanderluster could be something to do with USA pollution emissions not sure but modern diesel motors have very low emissions
😁 soon scientists will come up with vehicles with both diesel and petrol engines
because the marketing dealers wont be able to sell as much with last long vehicles
because city teens and 20-somethings will buy them to compensate for their insecurities, lift them into the fucking sky, tune them to blow black smoke, and throw on rubber band mud tires with oversized wheels, then never leave the pavement or do real work with them. those people are the reason the EPA is getting stricter and stricter with their diesel emission standards.
I just passed 348k miles in my 91 Jeep 4.0 petrol & still going strong. Keep up the maintenance & petrol can last just as long as a diesel.
I've been waiting for this video for ages just to end an argument I've been having with a mate since last year 😂
Usually, I'll go petrol for daily driving or having a sports car. But since I moved to Europe, if you want an off road vehicle here, diesels are much better options. Better fuel economy, filling up the tank is cheaper than petrol, there's a lot of support of parts for maintenance and that extra torque is well useful, too.
Also, it depends on the model. For example, Toyotas make bulletproof petrol engines that last forever, but I've heard their D-4Ds may have some issues. I would only choose Toyota if it's petrol. Otherwise, I'm thinking about getting a new Navara, Y61 Patrol or even a late 80s to mid 90s G Class, back when Mercs were solid built. All of them diesel, of course.
The region in which you live in has a lot to do with it. In the USA you can get gas at every gas station but not diesel.
Thats cause your country is shit
On the US interstates you can find diesel easily because of big rig traffic. While it's true because of demand not every fuel station has diesel , pretty much every town does. Even in 2008 when I drove from Clarksburg, Massachusetts to the San Francisco Bay Area, on mainly back roads trying to avoid the freeways, finding diesel wasn't even remotely difficult.
Diesel is offered in most areas of North America. There is no problem finding it.
I had a '79 Mercedes 240 with 700,000 miles and while the fuel economy was still great (+40mpg!) Rich is correct, in some areas it is hard to find diesel... At night, when every service station is closed but one...and it is raining. One thing the video didn't mention is the increased jeopardy diesel drivers face if they run out and need to crack lines to purge air! (Again, ask me how I know lol)
So, what I'm getting from this channel is a) we need black steel wheels with mud tires 2)diesel motor (deliberately overfueling to make soot) d) sleeve tatt, neck beard and southern cross stickers for back window of rig. What else do I need? Light bar mounted on bullbar?
One thing you didnt touch on is resale value which is better? Say after 5 years of ownership or even 10 years. For me i own a 1999 TD42 Patrol with nearly 400000ks and its still worth around 20k but same model petrol vehicle is worth only half that. If you live in Australia Diesel just makes sence.
The same logic applies here in the States, diesel has far better resale value.
Depending on the details diesel can still be more expensive...
Higher maintenance costs, more oil, more filters, more expensive filters, possibly def.
Financing costs. Diesel can be a 5-10k dollar option. Which can add an extra 500-1k dollar over to course of a loan.
Diesel engines depreciate, meaning they add 10k to the initial cost and return an additional 7k for resale... which is a loss. The overall depreciation percentage might be lower, but the higher cost can still mean that you lose more money on the car.
So yes and no, some diesels save you money and some don't.
Here is an interesting read.
www.google.com/amp/s/www.forbes.com/sites/matthewdepaula/2012/08/27/clean-diesel-cars-and-trucks-that-will-save-you-money/amp/
resale totally tops on a diesel, towing heavy loads a bonus on economy and torque
Rolly B resale is higher, but you can lose more money on it still.
I'll give you an extreme example.
I buy a Land Cruiser for $100k. After 5 years 60k miles it's now worth $60k. At the same time, my coworker purchased a Ford mustang for $35k, and drove it the same miles and sold it for $15k at the same time I did.
The LC only lost 40% value while the mustang lost 57%, but in the end the LC owner lost more money due to a higher initial cost to buy despite having a superior resale value.
Diesel doesn't give that much higher of a resale percentage here in the states and the engine option averages $5k, so many models do lose more of your money in the long run.
I posted an article earlier that outlined which models were more economical to get diesel.
the type of work a cruiser can do out weighs the work a Mustang can do, as they say horses for courses
Good factual points, but im guessing you guys have overlanding in mind. For short off road trails, the small Jimny/Samurai/Gypsy is ideal, can carry a few days of supplies anywhere you want where The larger diesels can struggle with its weight. The terrain is usually hilly and rocky where I live so I guess its situational at best.
Diesel for me!! Just need to seal the common rail sensors and computer in my case. Also a Turbo is awesome in a Diesel engine, so much more power. Great review Ronny!!
Melcahya Torque, not power
Dan Zeman both
Hi Ronny,
I was watching one of your vids on a 80 series. A question was asked "What is the first thing you would do to a stock standard vehicle?" The answer was legendary "Drive it". In my case no way I could afford a 10 00 diesel so got a trusty 1fz 80 series. So in regards to petrol or diesel is what ever get you out there is the better bet!
The main reason I do not have a diesel is because there are very few available in the US. Good comparison!!
Jim Stepkoski Do you live in a small town or something there is a crap ton of diesel trucks in the US. The scout ih came with diesels so did the dodges with a Cummins motor, ford with the power stroke, chevy with the 6.4 and Duramax engines. Most if not all US Humvees have a GM 6.4 in them and you can pick a used Humvee up for under 10 grand.
Almost all of the ones you listed are full sized trucks which are not good for offroading unless you get a single cab long bed version that gets it's wheel base in the golden zone.
The only modern contender is the colorado/canyon.
@@zososldier Bud that's not what my comment was leaning towards, he said there were few diesel trucks in the United States and I just named a few lol.
@@zososldier plus a extended cad short bed truck is kinda the same as a signal cab long bed so I wouldn't use that example.
The example is used because the new standard size truck is a quad cab short bed.Probably 80% of the trucks on any new lot are a full size 4 door with a standard bed for an average owner to easily fit a family of 4 (minus their fleet vehicle selection). The extended cab is also much more top heavy due to the added weight of the cab.
Seeing how there are no options I know of for a single cab short bed diesel (Maybe the dodge eco diesel but I am not sure), which would put it in the 120 inch range, the best option for an actual offroader that isn't too heavy for it's own good, leading to snapped parts everywhere and an increased risk of roll over, is the single cab long bed that has the diesel option. which puts it in the 130-140 range.
Either way. This option would get it's butt kicked when put up against an equally built solid axle toyota or wranger due to their size, weight and agility (due to being in the optimal 120 inch wheel base zone) benefits.
Again, the only diesel option for an offroader right now without major modification is the colorado/canyon.
Hi Ronny; I think you hit the nail on the head with this one especially in Australia. If your up for just running around town with the occasional weekend off road trip petrol's fine but if your serious about 4 wheel driving in the remote outback then diesel wins out every time.Good comparison though. I'd be interested to find out which expands more as I see a lot of trucks with very bloated red plastic cans on their roofs in the Aussie heat.Regards from bigezi
I wish there were more diesel options in the US. Having said that, longevity of petrol trucks/engines is way more than 5 years if you are moderately good at maintenance. I have a 2004 4Runner (Hilux Surf in AUS) that runs as good as the day it was made and it's been wheeled quite a bit. The Toyota 2UZ-FE petrol V8 is an amazing engine with quite a bit of torque. Would I rather have an Australian spec diesel Hilux? Sure, but i'm not going to lose any sleep over it. I do wish you would put the steering wheel in the right place though :) Great vids Ronny!
Surfs/4runner are known as the most unreliable toyota you can buy in Australia.
I watch your video on winching before every off road trip I do just to refresh. Love your videos!!
A V8 Classic Range Rover on an Auto box is a lovely vehicle to drive. A lot of fun on the road with an amazing burble. The torque converter eliminates any torque advantage the diesels have, and as horsepower = work done it will always win, and that’s what’s fun about a petrol. It’s a marmite thing, and very divisive. Great video Ronny.
Simon Aldred the diesel still gets better fuel economy and will last longer so you still lose. Try again you gas lovers diesel will always be the king
Josh lower it’s just a personal thing really. Both will get the job done, like Ronny says it’s what suits you that counts.
Simon Aldred the gas truck will break down first and is less efficient in what it does. Gas loses. Period
Thank you for understanding the relationship between torque and power.
Josh, Simon's comment completely went over your head. haha
Good job at tackling a sensitive issue. Anyone who is hard core either way isn't giving the alternate the dues it deserves.
All the modern petrol coil packs are sealed and up high and water crossing haven't been an issue in 10 years. Diesels are now way to unreliable with there DPF and ERG systems and to get anywhere near the power of an equivalent petrol you have to spend a fortune and make it less reliable again. As for life span of the engines think of it this way, one is naturally aspirated and there other has 25psi boost before you modify it to try catch up to petrol power.
The biggest problem with this debate is not enough people have owned both engines and only comment from one side.
the issue is that modern diesel engines have the same electronic controls as gas engines, therefore the biggest advantages are now gone, plus at least in USA the engines now have DEF, DPF, ERG, and DOC, so they have the same exhaust heat as a gas engine, the same fuel economy, are more complex, and are FAR more expensive, whereas on gasoline all you have is EGR and catalytic reduction for emissions controls, plus most vehicles wont care too much if you remove the cats, and in some cases CEL wont even come on properly, thus eliminating the field fire risk, Modern US diesels will throw an absolute fit until you reprogram the computer.
In the USA there is also the fact that diesel is less available than gas and is taxed higher in many cases, for example where I live gas is $2.47 per gallon, diesel is $3.97 per gallon and for the most part its taxes that make up the price difference, also in the US market usually gasoline engines are a far higher displacement than in eastern markets, thus with proper gearing they will crawl anywhere in first gear, in my case my unmodified BBF v8 will pull the truck hard enough to break 35-12.50s loose on gravel/mud/sand or on super steep inclines in 1st high at only 400 RPM with the idle screw turned in, even with my stock 3.54:1 gears
@@ghost-jesus GPF (Gasoline Particular Filter) are being installed in VW and Subaru. Possibly more, these I heard about so far. Soon second hand vehicles will have no value due to maintenance costs.
I often use J.Gr Cherokee with 3.5l V6 in Japanese mountains. It never sees over 3k revs and doesn`t sound like a farm vehicle. The only annoying thing is my bottom is too small for the seat. The owner is sumo guy so he is fine ;)
ghost jesus in NZ Diesel is a lot cheaper than petrol, even when we add road tax for the diesel fuel it still end up being cheaper. My vehicle can get 700km per tank being diesel where the same vehicle as mine in petrol will get 450-500km per tank with the tank being the same size. With that I’m getting more torque and close to if not the same kw. Diesel is a win for me.
@@Palpac in USA the diesel emissions equipment is getting the diesels down to the same fuel economy as a gas engine, plus the DEF consumption on the new ones is insane compared to a few years ago, plus modern diesels won't even burn cheap distillate, not to mention the older diesels are completely gutless, I can get a 7.3 that makes 200 HP@ 3600 385 lb ft @2200, requires a turbo for more power, or I can continue with my 7.5 gasser with 350 HP @3800 and 545 lb-ft 2200 and can be built further without forced induction
ghost jesus also from New Zealand, my 2.5l 4 cylinder Navara dual cab came from the factory putting out close to 500nm before being chipped. I don’t run crazy boost or anything silly like that but she’lllight up all 4 on gravel, sand etc with very little right boot. Chuck the lockers on and I can idle up rock steps on even the snow farm testing grounds near Wanaka where Audi, Benz etc test their G wagons and Quattro
Very informative for a offroad newbie like me, with all the different cases and pros and cons. Like it! 👍
I wish we got diesel engine options here in the states. It's so limited you can't get one hardly unless it's severely limited.
Thanks VW. Well and the EPA.
Are there not 25year import laws your could use as an option?
There is the 2.8L cummins diesel crate motor or the chevy ZR2 Colorado or you can wait for jeep to come out with a diesel in a year or two.
Was thinking more of offroading vehicles with diesels of which the ZR2 would be a decent option. I'm gonna see about the 3.0 Jeep diesel and decide on it.
Blue Yota the 2.8 duramax is an engine that's been proven in other countries for years.
Another consideration is 'where' are you going? Why? Fuel availability. Now, most people would autoresponse; diesel! Yes, diesel HGV's are very common. But wait a sec, what is the main form of motor transportation in Africa and Asia? The answer is small petrol motorbikes. Petrol for them is available everywhere. Not necessarily so for lorries. I have had far more trouble getting diesel in remote places than petrol. That is a major difference between 'off-roading' and 'overlanding'. Related to that, any bush mechanic can help you with a normal petrol engine. A high-pressure diesel pump? Good luck with that! Just something to think about. Cheers!
good comparison, I believe the main reason a diesel engine is heavier is on a petrol/gasoline engine compression is around 8 to 1. but on diesel at least 30 to 1 ( this is how the air gets hot enough to ignite the fuel ) .. so everything beefed up to cope with at least 4 times more compression
The diesel isn't as high as 30 to 1 but i get ur point
Most modern normally aspirated gasoline engines are around 9:1 compression ratio. Diesels are typically around 20:1. The higher compression ratio and less controlled combustion timing are why diesels have to be so much stronger and therefore heavier.
Mister510 close. Modern gas engines are over 10:1 for turbo applications and around 13:1 naturally aspirated now. Compression ignition engines have also come down to reduce NOx emissions, so 16:1 isn't uncommon.
obviously miss informed …. Eg 200 series cruiser engines: petrol 10.2:1vs diesel 16.8:1, !!! a lot of modern small Ltr ULP engine are heading toward 12:1 now days, technology is a wonderfull thing lol
Ben Winter didn't know that one
I’ve had a ‘97 Ford Powerstroke for 16 years and 355,000 miles. It’s still a beast. I have bought and sold four or five gas rigs over that time and all are gone for one reason or another, mostly due to poor reliability and fuel economy. The Stroker never lets me down.
This video blew my mind. I’m still recovering.
Hey guys. I'm not an expert in any area by any means but I don't agree with the statement at the 5:28 mark regarding that a gasoline powered engine revs higher because it's more controlled. As far as I know, it revs higher because the distance that the piston has to travel in the cylinder is smaller. Diesel engine pistons need to have a little bit more of travel in order for them to compress enough air so it can reach the correct temperature. Therefore longer travel, less rpm.
If I'm mistaking, please do tell me and I apologise if this comment isn't theme related.
Cheers.
Diesel engine are built stronger because of higher torque levels, massive compression ratio's with huge compression ignition values and also for long life reliability.
Common Rail Diesel is not "uncontrollable" ignition, it is precisely injected just like a petrol engine.
The older diesels engine are also not "uncontrollable" they just ignite the fuel at a less precise moment.
Petrol 4.7L Landcruiser engines regularly go over half a million KMS.
Diesel at idle burns less because it is diesel for 1 (More joules of energy per litre) and because it is not stoichiometrically locked with a certain Air Fuel Ratio.
A diesel (non common rail) also has no throttle plate causing pumping losses and this increases economy over Petrol.
Just my 2 cents worth.
Totally agree with your comments and your videos are clear, concise and informative. Well done as we need more people like you out there to educate more people. Love your cruiser by the way.
Yeaaaahhh... but Petrol is more fun though ;) Who wants slow and controlled when you can have screaming and jumping haha
Adolf Kleinhans some people don’t like being stuck in the middle of the outback with no fuel.
Soot gets the moot
I have a 21 year old 4x4 Rodeo 2.6 petrol that is still near original, still going strong. It also comes down to how you treat and maintain your vehicle.
sir, could you please explain suspension lift kits for IFS/IRS vehicles, i.e. tools, kits, coils and shocks and the process involved, would appreciate it.
i know you not giving away your lovely 70 series...but the reviews are very balanced..am sure it has helped alot of people who dont do the australian outback..those who prefer dual cabs with an auto get help here...thx...greetings from kenya
I dunno about the 5 year thing Ronny. Consider the Toyota 1GR-FE in the FJ's and Prado's is bulletproof, vs the 1VD-FTE which has had plenty of issues since release.
Diesel engines don't have the reliability they used to now that they have common rail, EGR, SCR and DPFs.
Agree some diesels are a bomb now, petrols are less problems and simple
Do you not understand generalities? What you are doing is anecdotal. In general, a diesel should go 300k miles or more. Most gas engines only go 200k.
Can a gas engine go more? yes. Perfect examples are taxi cabs. They go over 500k with a gas engine. But at the same time, there are semi trucks that go over 1 million miles or more.
The 5 year figure is also a vehicle turn over rate. Not life span. It's pretty much the average a person keeps a vehicle before buying a new one.
JP Onefourseven Exactly why i have the 1HZ toyota 6 cyl 4.2 diesel. None of that crap, old school indirect injection, and no computers or electronics. A real diesel 🙂
@@zososldier I don't understand. Maybe you can help. If 5 years is the average keep time of a vehicle would that not be vehicle's in general? I think he was referring to hard wheeling life span. Of which I don't agree with. My 87 xj 2.8l v6 gasser. At 450k with nothing more than a carb rebuild is not uncommon in the states. I think location plays a huge roll in what is and isn't valuable.
My little 4cyl Yota does fairly well off road, specially with the lower gear set. Down hill with a manual in low range I barley have to us the brakes. But at 350k on 95% stock components I’ve been on the fence about which engine conversion I’m gonna do. I can build a V8 with good low to mid range torque, but diesels have better torque to start with. Pros and cons of both, bottom line figure out what you want to do with the vehicle like building an engine. Figure that out and then do your pros and cons of the engine, once you got that build your rig, everything else will follow.
Great vids mate, looking forward to future updates.
Diesel for me- just bought an Isuzu D-Max with a long range tank. No fill ups for about 1600 kilometres.
mybe you should buy a front diff so you dont get stuck or roll over..never ever buy a vehicle with ifs,there weak,no travel,high maintenance.,it might break 1600 ks away from a cv garage.he he ,get a jeep front diff with uni.s,d44,stronger than any ifs.cheap & basic. cant beat american.
"Never buy a vehicle with IFS" - someone should tell all the guys with trophy trucks, boy are they going to feel silly!
Got a 2013 Pajero NW a few months ago and decided on the diesel mostly for the fuel economy over the V6 petrol, hope to own it for a long time, I don't tend to change cars often, my first and only new car lasted me over 20 years. Found out the hard way with the service costs, and some other work I've had done to fix things neglected by the last owner, oh got a catch can installed at the first service after they cleaned the intake, $2500 total for a service and the catch can.
Your right. I have 250000km on my V6 petrol hilux and it’s in the shop getting a new head gasket right now😡
michael dellar happened to my 3.4L V6 90 series. Engine’s never been the same.
Can definitely relate to more cost for parts. $4200 for a reco injector pump for a ZD30. Was thinking of converting to a turbo petrol, but after watching this.... looking at sticking to a diesel, might step up to a TD42 in the Patrol.
Tb48 turbo 😂😂 solved the lack of low down torque but damn is she thirsty
A bit rough on some of the explanations, but I think you hit the nail on the head. There are ways, though, to mitigate many of the petrol deficiencies (auxiliary reductions, stroker mods, waterproofing electricals), but they require serious investment and modifications and are better left for people who are capable of doing and maintaining those mods themselves.
Yes but all those mods combined still cost less than a set of diesel injectors that last 25% as long as petrol ones.. that's not to mention the $3,500 for a diesel fuel pump
I used to have a diesel 4x4 I nearly cried when I sold it I was so happy. Went to a petrol and never regretted it. Fuck the increased fuel costs, fuel is cheap. Fuel pump rebuilds etc on diesels are not. Modern petrols are fairly good on the juice even places like Fraser island now I average about 20l/100km.
If your having to do multiple fuel pump rebuilds/replacements, you're not doing maintenance or not adjusting your maintenance schedule for the shitty fuel you're buying. 275k/~440km and I've never had any issues with any fuel system components
Fuck im good, just ask me
Modern diesels are even worse. There have been many horror stories of them shutting down after being filled with poor quality diesel (high in sulphur) which is what you find in developing areas in africa and latin america and asia. There is one guy on youtube who drove across america and africa in a petrol wrangler for this very reason.
Ronny, what's with the 'gasoline' thing?. Dont forget that what makes your channel universally appealing is the Australian flavour. No compromises.
Did I imagine that? or did you do a sneaky edit and put 'petrol' in the title?
Unless buying GM there's no diesel options in North America at least not for smaller trucks. Unless buying a 3/4 ton or bigger. So we don't really have much of a choice but to have gas, all Toyota, Jeep, Ford are petrol.
I've owned vw diesels though and by far wish I could have a diesel Toyota. The torque is the best.
My only issue with diesel is in the cold climates here in Canada it can be a pain in the winter.
That has more to do with the shitty emission laws in the US. Diesel is extremely restricted in how much particulate matter you can put into the air, gas isn't. Because of that it isn't worth it for manufacturers to try and produce smaller diesel engines as it is easier, cheaper, and less restrictive to built larger gas engines.
Once you enter the 3/4+ arena it is definitely diesel is king, but for 1/2 ton and under trucks it is a gas world, especially with turbos.
Bnadit yep, and it's because of that I find it idiotic when people say they think Toyota will bring a diesel 4runner or Tacoma here. We'll see hybrid before diesel in North America
2.8L crate diesel from cummins
That is still a $9,000 engine though. If I could have it my way I'd put it in as the power plant in my off-road build, but when it costs more for the engine than it does for the truck and everything else it is very hard to justify.
Bnadit the crate engine costs more, but Diesel engines inherently cost more (as Ronny noted) plus you get a complete installation kit with that cummins crate.
the pros and cons are for very different scenarios. water crossings, long grass... never even thought of those, cause i aint wanna get those sensors wet
I drove only petrol cars for almost 25 years. I hated diesel, never owned a diesel car or truck. Recently, I purchased a diesel SUV. I fuking love it!!! DIESEL every day, all day!!!
i have a 1985 petrol and a 1986 turbo diesel 4runner and about the only downside i have come up with so far is that the diesel isn't as good on the highway, only just slightly better off road though, petrol one is much better at coping with the wind drag from roof top tent, the diesel struggled to get to 100 petrol will sit on 120 no prob, good vid keep em coming
In my short 5 years with the Army, the smell I'll always remember is the start of a shit ton of vehicles on a cold morning. That, and always having the smell of diesel on all my shit and hands haha.
SO even the Army uses diesel... hmmm...
1Mexikaner well the trucks are a lot heavier than commercial SUVs and pick ups
I drive a 4L v8 Land Rover Discovery 2 on petrol..plenty of torque with the autobox on low range and also engine breaking is good in low range 1st gear.. and it sounds awesome.
Having had both I would now have nothing but diesel in a 4x4. Engines last longer if you look after them, they are easier to maintain yourself even if parts cost more. They are better at producing low down power and my biggest criteria, they don't overheat as much as petrol engines. Petrol engines slogging through sand up north overheat like crazy. I don't care about fun on sand, i just want to get through it to my favourite fishing spot....oh and if you really need another reason to go diesel, when the oil wells run dry, diesels will still run on fuel produced by plant crops.
Thats true for old diesel cars.
Great Topic!!!!
Plenty of people so stuck in their old ways, modern petrols are pretty amazing.
I have a diesel, store diesel in my vehicle, no probs, but i'm not against Petrol
Why do you say that a gasoline/petrol engine will only last 5 years? I have a vehicle on its original engine with 300,000 miles/482803 km (who knows how many running hours) that is 23 years old and still running strong. Transmission could use some love if I find time for it...
I was referring to the 5yr change over many people do. Petrols will last a long time but diesel vehicles can looked as an investment vehicle
acephantom903 he's not saying they'll only last 5 years he's saying its probably not worth keeping petrols that long but as u say ur old rig has got some Ks on it and fine but I don't think any modern design petrol will last that long
ko _danjy I'm running a petrol with 176k miles on it. It's from 2002. Is that modern? Idk but I believe most off road worthy vehicles will have an engine that will last to 200k. But he is right that most people are swapping around 5 years. Would buying a diesel change that?
309,000 miles (497,287 km) on my 2001 xterra and like acephantom903 the tranny on the old xterra will need some work and or replacement soon. Diesel motors can go 3 times the distance for milage. One million miles on a diesel motor is not unheard of.
After the 5 year period the cost of owning a petrol starts to cost more then a diesel when you take in the cost of buying, maintaining and running. so buying a diesel may cost more outright but you compare costs over 10, 15, 20 years and the diesel is more cost effective in the long term generally speaking
Regarding water crossing I believe the most vulnerable part of the engine is the ECU and where it's located. If is somewhere that can get wet easily eg floor or engine bay that's game over. Modern coil pack petrols can be great in water. I've had mine running fully submerged for 3 minutes and never missed a beat. Not saying they are all like this but things have changes a long way since the old dizzy petrols VS mechanically injected diesels which are the main sourse for the diesels arguement.
