Cummins is the only true truck engine on the market 30-year diesel mechanic here all 18 wheelers use on inline 6 does Chevy Duramax is and powerstrokes may be alright engines but when it comes time to work on them they're a pain in the ass
7.3L with original transmission @ 440k miles. Still shifts great. Been doing a drain and fill every 25-30k miles since new with motorcraft fluid. Pan drop and filter change every 60-70k miles. Engine oil changes every 5-7k miles and have never even had the valve covers off it. That does NOT mean its a maintenance free engine!!! Change your fluids excessively (all of them!!!) and keep on top of the leaks and it will last! As for power. Sure it might not beat out a 6.7, but it pulls a 3 horse trailer every other weekend without problems all over TX.
@@Val-xi4we yep and pulling that trailer and working is exactly what it was designed to do, too often people treat their diesel’s like race vehicles and just beat the heck out of them, proper maintenance and proper operation and those engines will run forever , it’s actually good for them to be worked ( not beat on) but worked
2007 chevy 3500 duramax lbz 304.000 no problems yet , pulling 10 -14000 all the time , oil change every 5, 6 thousand fuel filter 10thousand rearend is getting worn , everything works , only 2 other people have ever driven it,love it , 12mpg pulling , empty 15 - 17 mpg love my chevy .
I work on them for a living and have 3 rams a 12v, 24v and a 6.7, from my professional opinion is I have seen more problems from 7.3 compared to 12v. Again I bad o-ring will make a bad day and a big bill. Still can’t find much on a 12v it’s fully mechanical
Yes… His name is Kyle… He has a few warrants in a few other states… Other than that… He’s a great guy who always shows up to work on time and never calls out… I just hope he gets those warrants handled before it’s to late…
He says the Cummins has a horsepower advantage but when it comes to low end torque, the Powerstroke wins. Most definitely the other way around by a long shot and anyone who has driven both - especially in a manual trans config - will agree. The v8 design is more about HP while the inline is more about torque, especially low end torque. Hopefully he just misspoke. I guess they've never seen a 12v Cummins with a manual trans come through their shop so they can't comment about the reliability of those.
I would agree about the Cummins being top dog in torque 10 year ago, but these new V8 diesels put down some stupid amounts of torque. I love my 6.7 Powerstroke. At 93K miles it’s been very reliable.
The 2020-2024 6.7 powerstroke is highly reliable platform and the best diesel ! The 7.3 powerstroke and lbz duramax and 5.9 Cummins strong reliable engines
6.7 powerstroke is incredibly prone to spinning rod bearings, cp4 injection pump and its subpar ccv design.. I’d say it’s far from the best engine out there. Makes good power though!
Man here with a 2002 Dodge 2500 4x4 with 6 speed with 5.9 Cummins it has 332,428 miles on it no major issues with the engine minor oil leaks still running original injectors and original turbo ! I have changed the exhaust to 4 inch from 3 inch put a cold air intake on it bigger exhaust manifold and bigger air intake horn to help keep it running cool when towing up the mountains here in Tenn.& North Carolina bought it new in 02 best most reliable truck I've ever owned ! I do have an Edge 5 stage comp box stacked with Smarty box ! If I ever have injector trouble or turbo trouble then I'll upgrade the injectors to 100 horse injectors with a comparible turbo ! But right now it's doing fine ! Plenty of low end torque & decent top end torque ! I tow a 16' car hauler & a 10,000 lbs camper with this truck ! Awesome truck !
Same here man 2001 Dodge Ram 2500 4 x 4 6-speed Cummins 8 foot bed 460,000 Mi on it no problems ever with the truck no oil leaks no injector problems and whenever I do have to do anything on the engine it's easy to work on Cummins is the only true truck engine on the market those power strokes and Duramax or just made for the pickup truck Market flip the hood on any 18-wheeler today you're not going to find anything other than an inline 6
My buddy has a 7.3 with 750,000 miles on it. Same transmission, 3 torque converters. Tows heavy machines. Ive owned 3 now. Just about to hit the 300k mark. No real issues. Water pump recently. Small shudder in the trans in first gear. Needs new up pipes thats it. Been lucky. Solid engine
Great information.... but I'd rather see info about newer diesel trucks (2015+), as we all know the older pre DPF & DEF diesels were generally more mechanically reliable. Getting harder to find these 20-30+ year old trucks in decent working order up here in the rust belt.
I’ve had a 7.3 ford 6 speed. 06 Cummins automatic. 06 lbz automatic, 08 lmm automatic, 10 lmm automatic. And now a 12 6.7 Cummins 6 speed The duramax for me takes the cake. Specifically the lmm duramax. Never lost a race and out pulls anything I’ve driven.
My dad had a 7.3 ford and a 06 dmax.... the chevy was badass but always would cut power and go into a limp mode type thing.. he replaced pretty much everything on it and it always had that problem..sold it
@@patrickroach7289 Yeah I will stand with you the 5.9 Cummins is a really good if not the best diesel when it comes to pickup trucks, but the truck itself was horrible, one of the worst trucks out there that's why the 7.3 takes the cake in my opinion because the body doesn't fall apart like a tin can.
2002 GMC Sierra 3500 SLT Crew Cab Dually Slung a exhaust valve cylinder 8, drove another 1500 miles. Never quit on me, rebuilt the engine in my garage at 301,500 miles, destroyed the suspension and differential, replaced entire suspension and replaced the diff with an 18 wheeler 6 planetary gear differential that kept the same axle and bearing firment, aftermarket turbo (delayed wastegate) Complete paint job, 245s all the way around, garage built and welded front and rear steel bumpers with brushgaurd. Ive changed my oil every 6-7k miles, fuel filters every 8-10k, clean the air filter and oil it every 5-10k (really depends how much dirt i see caught in it) here it is 329,000 miles and still getting 20mpg, will smoke the tires, oil is still amber yellow clean, peppy as all hell and has the rear end to pull any and everything I want it to. The Allison 1000 5 speed? Is the last man standing and has never been touched. It has literally outlived everything else around the truck. Still shifts like a dream, smooth and efficiently. I love my LB7, would not trade it for anything. In my opinion its the simplest to fix and maintain, best fuel economy ive ever seen on a Dually and I absolutely love how they sound. Definitely in the Top 5 in Diesels
I should mention this truck for its entire life had a 9,000 pound welder in the bed 24/7 since 24k miles and my Papa didn’t abuse it but he definitely worked the shit out of it
I love the Cummins 5.9, but I have to say that it seems like every part of my '99 Ram 3500 that is made by Dodge was crap. Luckily, most of the drivetrain wasn't made by them.
The 7.3 was a very under stressed engine and in my opinion after driving semi for close to 45 years and being in the industry all my life that is the biggest factor besides maintenance in longevity, there’s a reason the price of a factory warranty from Cummins goes up in price the higher the power setting/rating on a specific engine like the ISX 15 for example the warranty price between a 425 and a 500 is huge
He's never worked on a 12 or 24 valve Cummins I guess none of them has never entered his shop, so there you go that's the real winner the one he never brung up
Had a 6.7 Powerstroke 6 speed trans with 261k miles. Never changed fluid. Then it started to shift very aggressively so I had a trans flush and it made it night and day better
All these engines are reliable it's just like everyone says , do your maintenance. And I think the only thing that makes older engine seem more reliable is that you could neglect them constantly and they would still run fine these newer engines can't be neglected need constant Maintenance, such as oil filter changes fuel additives making sure your DPF completes a regen, just more headaches these days.
@@curtischung1009 Cummins make their peak torque at low RPM regardless of final drive ratio. The current Cummins ISB hits peak torque by 1,600 rpm which is the same place the Powerstroke does. The Cummins just redlines a little earlier than the PS>
Cummins has less torque low and than the new stroke. They also changes things on the motor that made my buddy go to Ford. He was Cummins since they started. The 5th gen’s suck
I had a 95 and 2002 with 7.3's, loved the motor and hate the ford trans. Rebuit the 95 E40D trans at 70K and replaced the 2002 R4100 trans at 120K, Swithched to Ram 3500 with 6.7 with the HD Aisin trans. On my second with a dually and love it!!
I have 2- 97 Ford 7.3s. Both still run great. My thinking is their longevity is because they're not tuned to give max horsepower, thus, less stress on engine parts and drive train parts.
On the trans service, draining about 2 quarts, need to put in a drainplug, every 50k and then refilling will help keep the fluid clean while not causing the problems from a full service.
So wrong. Not the most power, nor the most torque (stock) but definitely the most reliable is the 12 valve cummins first gen, and early second gen dodge ram 5.9. That's why people are willing to pay 30-40 grand, sometimes more, for a 30 year old truck.
I Agree Completely. I have a P-Pump,12 valve 5.9l (1998.0 just before they changed to the 24v in 1998.5), 3500 Dodge,5 speed, 4x4 that I bought New myself and I have been the only driver. It's without a doubt The Best Diesel Truck I've had. I've had 0 issues with it. I have pulled Crazy Big Loads with it passing Everything on the road. It's 26 yrs old and still going Strong
@@joetarpley1066 I've got my grandpa's 94 with a 5 speed. He ordered it specifically to pull a big fifth wheel. In 98 we took a 6000 mile trip across the country. They only offered a single cab so it was kinda tight while traveling but I'll always remember them. I was fifteen then. In 2020 I was offered 40 grand for that truck. Only had 110k miles on it at that time. So under 150k. It's still in my driveway and I'm glad it's still there. Sure miss my grandparents.
The 7.3 powerstroke and 12v 5.9 cummins are very comparable in longevity. The 12v 5.9 is more reliable than the 7.3. The 7.3's HEUI fuel system is far more complex than the 5.9's mechanical fuel system. Both engines are easily capable of 800k+ miles when maintained correctly. The 7.3 will require more maintenance along the way. The 7.3 sits in a better truck than the 5.9 does, so the 7.3 still gets my vote. I've owned both. I'd rather deal with a bit more maintenance on a 7.3 than deal with owning an older dodge truck.
I got a 2011 ram 3500 6.7 Cummins that’s just been maintained with a eco tune, inline dual fuel filter and bypass oil filter. Filters/oil get changed once a year. Got 376,000 miles mostly hotshotting for a time. Only thing that gave out was the 68RFE at 130,000 it got full rebuilt inside/billet guts now and shifts like butter.
@@justinalderton7485 yeah but when I did that their weren’t drop in ready Aisons in the junk yard, the 68 I got now is stronger than a stock aison and shifts smoother.
I drove a 7.3 from 2000 to 2010 and it was good but not as good as my BulletProofed 6.0. I've had zero problems with it or the truck it's in. It is just better all around.
None of them created the diesel or their diesel. Power stroke use to be made by international, Cummins is made my Cummins, and the duramax is made by Isuzu
Why I like the Fords. The new ones are Fords. Ford engine and ford Transmission and Ford Body. Chevy is Duramax Isuzu. Transmission is Allison and Dodge is Cummins with Aisin Transmission. And the New Dodge Trucks are made in Mexico not USA and the Chevys. Look inside your door jam. Both my trucks say Made in USA.
@@timothydare6007The new "Dodge" after 2008 is not even a Dodge. It's a FCA Ram truck. Nowhere on the truck or title work do you see the name Dodge anymore. It is owned by Fiat or FCA.
@@timothydare6007Dmax was a joint venture between GM and Isuzu. Until 2007 the design was done in Japan by a combination of Isuzu and GM Powertrain engineers but mid 2007 GM took over majority stake and moved the design to Michigan. The engine has until recently always been manufactured at the joint venture Dmax plant in Moraine Ohio! As for transmissions they were either manufactured by Allison a subsidiary of GM or by GM directly so the driver lines have always been under GM control! I’ve worked at all three engine manufacturers Cummins in Walesboro In, Navistar in Indianapolis In, and Dmax in Moraine Oh and can tell you that each of those sites were world class diesel manufacturers who cared very much about their customers!
I never had a problem with the motor on my truck but the transmission had to be replaced at 75 K miles I never did a break job on it it had 210 k when I sold it, it had massive break pads on it
Cummins low end toque at 1900 rpm red line 3200 all v-8 have wind up a lot higher to get same toque v-8 redline in the 5000 rpm range Cummins for the win
@@That_1_E90if they put the p pump in with the 24v I think you might be right. But that's the real draw to the 12v. That injector pump was/is one of the best things paired with a cummins
12v is more reliable than the 24v except for the HPFP (high pressure fuel pump) you just put the vp44 from the 24v (this will make your 12v sound like a 24v) and you got yourself the most reliable engine
@@blackwoodechoes vp44 is electronic is absolute junk 3 plunger rotary pump with horrible cooling you got it backwards buddy a 215 mechanical p7100 injection pump is king of reliability that's a sin to put that junk on a 12valve
LB7 Duramax owner here.. I agree that the 7.3 is probably the most reliable. I say this because I'm literally sitting in my 7.3 F-450 tow truck with 491,000kms (you can do the math for miles). It's running up to 16-18 hrs a day, with about 50% of that is idle time. It gets zero maintenance. Not by choice, it's the company I work for. They don't have a maintenance program for their equipment. The trucks get maintenance when they break down, and even then it's usually just an oil change. I've been driving this truck for 3 years and it's never had filters done that I can remember, don't think the fluids have been changed in ages. Diff fluid smells like rotten frogsh*t, Not even the oil filter has been changed for a couple years because the rear main seal leaks oil like a shotgunned bucket. ( I have to dump a half gallon in every 10 days or so.) So I guess they figure the oil never gets dirty, so why change the filter? I don't know what they're thinking or why. But my point is that I work this truck for 12-18hrs a day, towing heavy loads, often working the PTO for long periods. I put about 300kms a day on it on average, and when business gets slow, it idles sometimes for hours between calls. Damn thing hasn't been shown any mercy in the 6 years I've been with the company. And she always starts in the morning, and she always gets me home the next morning. As for my LB7 Duramax, it's not far behind on reliability. It's got it's quirks, for example I'd prefer the injectors to be on the outside of the valve covers instead of under them. So it's not major surgery to change them out, but beggars n choosers n stuff... It's got almost 385,000 kms on it and she purrs like a kitten and pulls like an ox. Not a puff of smoke, even when I'm hard on the throttle. Even despite being mildly upgraded with some go-fast injectors and an edge evolution tuner, it still blows nothing but hot air out the back. A couple things the Duramax has that the 7.3 simply can't even get close to is (in my opinion) #1: fuel economy! I average about 18.5mpg Hwy in my 3500 Silverado Crew cab, long box, 4x4 dually (just sayin, it's a heavy ass truck). My 7.3 tow truck drinks about 12 mpg on the hwy. It's not even close. In fact every 7.3 I've ever driven was a diesel pig, some worse than others. Had an old flatdeck F550 with a non turbo 7.3, and I tell you.. with your foot to the floor, 0 to 60 was probably about a minute, and worse with a concrete pump towing behind. And the second thing I personally like about the D-max vs the 7.3 is.. (and I know it must be an illusion because I've seen the numbers).. I find the D-max has a longer torque curve. It keeps pulling hard no matter where the rpm's are. Whereas I find in my 7.3 that it's gutless above 2,000rpm. And I've driven several 7.3 tow trucks over many many years, so I'm not basing it off only 1 engine. The 7.3 will pull anything, just not quickly. The Duramax (older ones) will pull anything, and be quick about it. My vote for Best overall Diesel engine is split between the old 12valve Cummins units and the 1st gen D-max LB7. Wow, I ended up writing a damn novel here. It's a slow night, I haven't had a tow in hours, so this happens.
When it comes to older auto transmissions. Just change the filter and fluid in the pan. Never do a flush idc even if its only got 20000kms or miles, Never flush it. I change the filter and oil in the pan every 75000kms its a $50 service that's never failed me and my trans fluid has always been clean.
I would say for ultimate reliability and durability - the Gen 1 Dodge Ram Cummins would be my choice for most reliable. The Problem with newer diesels are two fold: Gov't emission regulations and customer power demands, both those are making the engineering process much more complex, which leads to less reliability (as it ages) and maintenance requirements throughout the ownership years.
@@rockstarsofspeed4008 pre emissions so 94.5 to 97 with the 03 Intercooler upgrade. Or any of the 00-03 ones. Newish interior and motors push out alittle more power
There is a diesel mechanic in Blanco tx. That says that the 7.3 is supior to the 12 valve,but he will say the 12 valve is a excellent engine. When you drive into bam's shop you will see 50ty diesel pickup trucks and 60ty days wait time.
The 7.3 in no way is better than a 5.9 Cummins. That 5.9 was put in all types of medium duty trucks. Inline is always better than V8 in diesel configurations
Hate to say it but 7.3 were built the best, stock 5.9 can certainly out pull a stock 7.3 but longevity the 7.3 takes the win. I’ve used all of em at work pushing them to the limits. 7.3 just look at the rods on them not even the new 6.7 Cummins rods are as big as the 7.3 still have the heaviest and biggest piston rods to date, it’s to bad they didn’t keep the 7.3 and went to the 6NO
You can go to UA-cam and see your comment out the window. There are many videos of 7.3L Power stroke literally catching the truck turning over a million live going down the road so push but push evenly.
All time Best diesel engine ever produced Cummins 12V, least amount of problems occurred during longevity Duramax, mostly seen in a shop being repaired Power stroke. All In My Opinion based on what I have personally witnessed working hands on. I’ve witnessed these top 3 engines run well over 500k miles. Maintenance is obviously the most important. Take care of it and it will take care of you.
I’ve had a 7.3 powertroke, plan on injectors every 5 years (regardless of maintenance schedule) and glow plugs every other year, water pump every 5 years which costs $450, compared to $80 for a 12 valve Cummins which can be changed out in less than an hour, ever changed out a 7.3 water pump? It sucks
Good video! This would have been a great video had they talked more about modern day diesels. What combination of engine & transmission? Then separate that answer to which transmission is the most reliable. When/how to service transmission? Which of the big three manufacturers have the best warranty to go with the truck? Which of the big three manufacturers have the best extended warranty if they offer one and is it worth it? what have they found to be the best oil to run in these engines especially in cold climates? Additives? How often should you change the engine oil? Filters?
I think this was good Contant, should’ve been longer with more questions on maintenance and preventative maintenance. I would like to see a part two also with a different dealer and a different mechanic shop.
Can’t tell you the best, but I can tell you the worst. Ford 6.0. I’ve had divorces that were way cheaper……. And I got rid of my last one. I lost friends. Because I realize we were only friends because we had 6.0s. We no longer had anything to talk about.
Yeah, the 6.0 could be reliable if you did $25,000.00 aftermarket bullet proofing. Without that, they're garbage mine made Me go broke and I did all the work.
@@Barabus-yx2cn def don’t need 25k to make em reliable. Especially if you know what your doing and don’t tune the piss out of it. I was just saying to the other guy that the 6.4 is much worse than the 6.0.
I don't even know why the 7.3 keeps getting brought up. It's so slow, underpowered and outdated it should already be forgotten. Almost any gas engine made today in a Full-Size truck outpowers it LOL. My LBZ was an awesome Diesel. No DEF crap and had great power once I straight piped and tuned it. What an awesome motor that was and I kick myself in the but for selling it. I actually got fed up with the DEF Diesels that i bougth a 7.3 gas ford and man do I miss diesel power. Now I'm wanting to go back to a diesel and trying to find me something I can rely on. I may go used.
Great interview. It's funny I use tonhate diesels cause of smell. Then an investment man told me about 7.3 n how he bought a bunch new and kept in storage n flipped them for profit cause they're Saught after
Ask gale banks hes been tearing apart diesels for over 40 years. He recommends duramax. They have always use the displacement of 6.6 liters. And manage to still crank out more horsepower and torque every year without changing the displacement. Cummins and powerstrokes have different displacements. Also you cannot beat isuzu and the chineese at building diesels
Would have been good to list the top 3 most reliable in order. Not a ton of 7.3's out there at this point. And they can be in rough condition overall even if the engine is solid.
School boy is wanting to hear his 7.3 is the best motor out there. Pushing to hear that. I have both and the 7.3 has given me way more problems than my 5.9. 5.9 has been super solid
Depends on what year I guess? I have a 2006 with 525,000 miles, and I still drive it. I did have the transmission rebuilt at 325,000. I don't know what more a guy could ask for?
@@SuperSnakePlissken I don't know about that. I own a construction company. I've had a lot of trucks. Never had a problem with Dodge trucks. Sorry you can't handle the truth.
The main issues around the cummins have started with bad decisions with dodge. The common issues are 1. Killer Dowel pin, 2. Cheaped out on 1 piece exhaust manifold, 3. poor fuel supply lift pumps, 4. Grid heater bolt failure Every Generation of engine has had their issues. They are great engines no engine is perfect.
What people do not get is that the more power the engine creates the less reliable its gonna be. Its a lot of stress on the engines to create that power where the 7.3l didn't which is why it was more reliable. Go take a 7.3l make it high output, but 100s oof thounds of miles.on it and make millions of them. You will not hear everyone saying its the more reliable anymore.
So I bought a new F-250 in 1985 and I had the 6.9 , do you ever see those motors anymore? My understanding is the 7.3 was a bored out 6.9. For small diesels you can’t go wrong with a International. International used to build a diesel DT466 for medium duty trucks and it was a work horse you just couldn’t kill it. It was just a great engine.
I think they're going to really come down to if they're modded, and if so, how much. Mild mods are probably okay, but anything more will take its toll.
Not so much "reliable" but "robust" might help as all of these items require servicing so those that are built truly like a truck that is a lot more than engine and powertrain although absolutely spot on there is that. My take is "Dodge is getting there" the only true disaster in big trucks in 1990s so they still remain at the bottom even today. GM did go BK and worse than that needed a bailout (same true of Chrysler tho why this happened to Chrysler I have no idea...twice now actually) so that leaves Ford which was nearly felled by the Ford Explorer Firestone tire disaster but seems to have very much learned from that. Tesla is definitely making noise now tho and this has helped out *ALL* buyers in the entire Industry excepting...incredibly...Toyota the one and only Best Of in this 3 threesome until now today.
egr kills engines, carbon. little diamonds in your cylinder. Old Cummins 12 and 24 P pumps. 100k rack. 12,000-mile service. on road! not you're going to work 12 miles and to the store. Diesels need highway running to maintain heat and running clean. Power increases kill the longevity of the engine and drivetrain. Transmissions. 46re 47re. 60k fluid filter, band adjustment. never flush. 400k 500k easy pulling trailers. 24 valve with vp44 pump replace supply pump with a fass pump. Cummins replaced Ford and GM here.
The only diesel engine on the market for these pickup trucks that's an actual truck type engine is the Cummins flip the hood on any 18-wheeler and you're only going to see one type of engine inline 6 cylinder Cummins is the only one that makes that engine
That’s actually a myth about servicing the transmission. You won’t have so much debris and or a clogged filter from servicing the unit. This guy has no idea what he’s talking about. A new filter will capture all of the “debris”. The smallest debris can cause problems and if there were debris in a trans it would cause issues quickly
ford didn't make the mistake of moving to the 6.0, the EPA made that mistake for them as the 7.3 couldn't keep up with the tighter emissions standards. the 6.0 and 6.4 never got a chance to shine as uncle sam broke them before they were even born. their emissions controls systems were their biggest down fall, if not for EGR and DPF these engines actually wouldn't have been half bad. in terms of long block design the 6.0 was short some head studs making back pressure more problemmatic for the head gaskets. the 6.4 was built like a tank, it had potential to be great but it wasn't all good. while most of the engine is very tough it's biggest weakness was it's soft pistons which might have actually been fine if not for the DPF system. the regens raised the EGTs to a point that it stressed the weakness of these pistons and cracked them which resulted in recalls that navistar refused to fulfil and one diesel engine failure after another pissed off ford breaking their partnership with international. the 4th gen power stroke engine made by ford called the scorpion, is actually a great engine even with it being all corked up that thing is a monster.
Any diesel engine that is taken care of and not abused will last a long time. Any diesel with power adders and abused, as well as, inefficient tunes will have issues. The fact they never even mention a 5.9 L Cummins means they never see them, speaks volumes.
Ford 7.3 power stroke I have a 1999 F350 still drive it today I don’t give a shit what anybody says absolute workhorse I wouldn’t trade it for any Duramax or Cummins out there
That’s great guys,I agree that the 7.3 diesel is a great engine,but it hasn’t been used since2003. I would like to know what is the most reliable diesel engine that is used now,like maybe in the past 5 years.
Guys they are not necessarily wrong saying the 7.3 is the most reliable diesel engine, it’s simply because they have never seen a 12 valve in their shop, they don’t break so they don’t even know it exists.
Never once did I hear anything about the 5.9 Cummins…. Only talked about the new ones… 5.9 12v and 24v are just as or more reliable than the 7.3. Hands down.
All engines have some sort of issues. I know for a fact that most diesel shops will tell you that they would be out business if it wasn't for power stroke or duramax
Sorry I have to disagree the 7.3 is a great engine but the older 12v Cummins is my absolute favorite motor my last one was still running strong at 350k
2006 5.9 cummins, last year no emissions. Best, easy to work on and great power and mpg.
Cummins is the only true truck engine on the market 30-year diesel mechanic here all 18 wheelers use on inline 6 does Chevy Duramax is and powerstrokes may be alright engines but when it comes time to work on them they're a pain in the ass
7.3L with original transmission @ 440k miles. Still shifts great. Been doing a drain and fill every 25-30k miles since new with motorcraft fluid. Pan drop and filter change every 60-70k miles.
Engine oil changes every 5-7k miles and have never even had the valve covers off it.
That does NOT mean its a maintenance free engine!!! Change your fluids excessively (all of them!!!) and keep on top of the leaks and it will last!
As for power. Sure it might not beat out a 6.7, but it pulls a 3 horse trailer every other weekend without problems all over TX.
@@Val-xi4we yep and pulling that trailer and working is exactly what it was designed to do, too often people treat their diesel’s like race vehicles and just beat the heck out of them, proper maintenance and proper operation and those engines will run forever , it’s actually good for them to be worked ( not beat on) but worked

He didn’t even mention the 12 valve Cummins! That engine is right up there with a 7.3 power stroke if not better.
The 12 valve is hands down the most reliable ever. But they started out as tractor engines so that makes sense.
12 valve most reliable!
I would say hell off a lot better no high pressure oil system to fail, 5.9 p7100 vs 7.3 it ‘s Cummins all the way on that front
I've owned both. And no it's not
I work on them for a living and have 3 rams a 12v, 24v and a 6.7, from my professional opinion is I have seen more problems from 7.3 compared to 12v. Again I bad o-ring will make a bad day and a big bill. Still can’t find much on a 12v it’s fully mechanical

Apparently the 12 valve Cummins lasts long that they have never had one come in for repair?
They're easy to work on, so despite your joke, I wouldn't doubt it, lol
He says the Cummins has a horsepower advantage but when it comes to low end torque, the Powerstroke wins. Most definitely the other way around by a long shot and anyone who has driven both - especially in a manual trans config - will agree. The v8 design is more about HP while the inline is more about torque, especially low end torque. Hopefully he just misspoke. I guess they've never seen a 12v Cummins with a manual trans come through their shop so they can't comment about the reliability of those.
Not really by a long shot, especially with the new high output 6.7 powerstroke there's no competition
The 2020+ 6.7 has so much more power than the 6.7 Cummins it’s not even comparable
Yeah the 6.7 Powerstroke is 100% much more powerful
I would agree about the Cummins being top dog in torque 10 year ago, but these new V8 diesels put down some stupid amounts of torque. I love my 6.7 Powerstroke. At 93K miles it’s been very reliable.
I don't think he's was talking about rated HP, yet the "power" put to the ground.
The 2020-2024 6.7 powerstroke is highly reliable platform and the best diesel ! The 7.3 powerstroke and lbz duramax and 5.9 Cummins strong reliable engines
I definitely wouldn’t say best diesel but still decent
The 6.7L powerstroke is only good if you get the DCR conversion by S&S
6.7 powerstroke is incredibly prone to spinning rod bearings, cp4 injection pump and its subpar ccv design.. I’d say it’s far from the best engine out there. Makes good power though!

What year is it if you don't mind me asking? Is it the F250 or F350? 🏁🤔🏁
Great information.... but I'd rather see info about newer diesel trucks (2015+), as we all know the older pre DPF & DEF diesels were generally more mechanically reliable. Getting harder to find these 20-30+ year old trucks in decent working order up here in the rust belt.

2002 GMC Sierra 3500 SLT Crew Cab Dually
Slung a exhaust valve cylinder 8, drove another 1500 miles. Never quit on me, rebuilt the engine in my garage at 301,500 miles, destroyed the suspension and differential, replaced entire suspension and replaced the diff with an 18 wheeler 6 planetary gear differential that kept the same axle and bearing firment, aftermarket turbo (delayed wastegate)
Complete paint job, 245s all the way around, garage built and welded front and rear steel bumpers with brushgaurd. Ive changed my oil every 6-7k miles, fuel filters every 8-10k, clean the air filter and oil it every 5-10k (really depends how much dirt i see caught in it) here it is 329,000 miles and still getting 20mpg, will smoke the tires, oil is still amber yellow clean, peppy as all hell and has the rear end to pull any and everything I want it to.
The Allison 1000 5 speed? Is the last man standing and has never been touched. It has literally outlived everything else around the truck. Still shifts like a dream, smooth and efficiently.
I love my LB7, would not trade it for anything. In my opinion its the simplest to fix and maintain, best fuel economy ive ever seen on a Dually and I absolutely love how they sound. Definitely in the Top 5 in Diesels
I should mention this truck for its entire life had a 9,000 pound welder in the bed 24/7 since 24k miles and my Papa didn’t abuse it but he definitely worked the shit out of it
I love the Cummins 5.9, but I have to say that it seems like every part of my '99 Ram 3500 that is made by Dodge was crap. Luckily, most of the drivetrain wasn't made by them.
Hey, you bought a Cummins, it just came wrapped in a Dodge.😂
@@steverempel2728 I know several guys that put souped up cummins in their F-350s since they hated Dodge, but liked Cummins.
The 7.3 was a very under stressed engine and in my opinion after driving semi for close to 45 years and being in the industry all my life that is the biggest factor besides maintenance in longevity, there’s a reason the price of a factory warranty from Cummins goes up in price the higher the power setting/rating on a specific engine like the ISX 15 for example the warranty price between a 425 and a 500 is huge
He's never worked on a 12 or 24 valve Cummins I guess none of them has never entered his shop, so there you go that's the real winner the one he never brung up
Had a 6.7 Powerstroke 6 speed trans with 261k miles. Never changed fluid. Then it started to shift very aggressively so I had a trans flush and it made it night and day better
All these engines are reliable it's just like everyone says , do your maintenance. And I think the only thing that makes older engine seem more reliable is that you could neglect them constantly and they would still run fine these newer engines can't be neglected need constant Maintenance, such as oil filter changes fuel additives making sure your DPF completes a regen, just more headaches these days.
These guys speak truth.
At my company we use Ford 6.7 And 2015ish Duramax.

@@curtischung1009 Cummins make their peak torque at low RPM regardless of final drive ratio. The current Cummins ISB hits peak torque by 1,600 rpm which is the same place the Powerstroke does. The Cummins just redlines a little earlier than the PS>
Cummins has less torque low and than the new stroke. They also changes things on the motor that made my buddy go to Ford. He was Cummins since they started. The 5th gen’s suck
I have had several Cummins and in my opinion the 5.9 Cummins 12v is the most reliable
World record is a 5.9 Cummins with 1.7 million mile !! Can't argue with that😅😅😅😅
Love my 03 5.9 HO. The problem is keeping the Dodge from falling off the Cummins.
Cummins is the only company that makes a true truck engine it's an inline 6 just like every 18-wheeler that runs the road today
5.9 Cummins first gen most reliable hands down .
I had a 95 and 2002 with 7.3's, loved the motor and hate the ford trans. Rebuit the 95 E40D trans at 70K and replaced the 2002 R4100 trans at 120K, Swithched to Ram 3500 with 6.7 with the HD Aisin trans. On my second with a dually and love it!!
I have 2- 97 Ford 7.3s. Both still run great. My thinking is their longevity is because they're not tuned to give max horsepower, thus, less stress on engine parts and drive train parts.
On the trans service, draining about 2 quarts, need to put in a drainplug, every 50k and then refilling will help keep the fluid clean while not causing the problems from a full service.
I have an old Diesel Dodge with 2,000,000 miles. Never had an issue. I actually haven’t even changed the oil in the last 5 years. She runs clean
So wrong. Not the most power, nor the most torque (stock) but definitely the most reliable is the 12 valve cummins first gen, and early second gen dodge ram 5.9. That's why people are willing to pay 30-40 grand, sometimes more, for a 30 year old truck.
I Agree Completely. I have a P-Pump,12 valve 5.9l (1998.0 just before they changed to the 24v in 1998.5), 3500 Dodge,5 speed, 4x4 that I bought New myself and I have been the only driver. It's without a doubt The Best Diesel Truck I've had. I've had 0 issues with it. I have pulled Crazy Big Loads with it passing Everything on the road. It's 26 yrs old and still going Strong
@@joetarpley1066 I've got my grandpa's 94 with a 5 speed. He ordered it specifically to pull a big fifth wheel. In 98 we took a 6000 mile trip across the country. They only offered a single cab so it was kinda tight while traveling but I'll always remember them. I was fifteen then. In 2020 I was offered 40 grand for that truck. Only had 110k miles on it at that time. So under 150k. It's still in my driveway and I'm glad it's still there. Sure miss my grandparents.
The 7.3 powerstroke and 12v 5.9 cummins are very comparable in longevity. The 12v 5.9 is more reliable than the 7.3. The 7.3's HEUI fuel system is far more complex than the 5.9's mechanical fuel system.
Both engines are easily capable of 800k+ miles when maintained correctly. The 7.3 will require more maintenance along the way.
The 7.3 sits in a better truck than the 5.9 does, so the 7.3 still gets my vote. I've owned both. I'd rather deal with a bit more maintenance on a 7.3 than deal with owning an older dodge truck.

Thank you for the video. I'd be most interested in the most reliable modern diesel...as if I were buying a new one off the lot tomorrow.
Good questions and content esp about the transmission. Keep it up. 7.3 all the way 🇱🇷
LB7 Duramax owner here.. I agree that the 7.3 is probably the most reliable. I say this because I'm literally sitting in my 7.3 F-450 tow truck with 491,000kms (you can do the math for miles). It's running up to 16-18 hrs a day, with about 50% of that is idle time. It gets zero maintenance. Not by choice, it's the company I work for. They don't have a maintenance program for their equipment. The trucks get maintenance when they break down, and even then it's usually just an oil change. I've been driving this truck for 3 years and it's never had filters done that I can remember, don't think the fluids have been changed in ages. Diff fluid smells like rotten frogsh*t, Not even the oil filter has been changed for a couple years because the rear main seal leaks oil like a shotgunned bucket. ( I have to dump a half gallon in every 10 days or so.) So I guess they figure the oil never gets dirty, so why change the filter?
I don't know what they're thinking or why. But my point is that I work this truck for 12-18hrs a day, towing heavy loads, often working the PTO for long periods. I put about 300kms a day on it on average, and when business gets slow, it idles sometimes for hours between calls. Damn thing hasn't been shown any mercy in the 6 years I've been with the company. And she always starts in the morning, and she always gets me home the next morning.
As for my LB7 Duramax, it's not far behind on reliability. It's got it's quirks, for example I'd prefer the injectors to be on the outside of the valve covers instead of under them. So it's not major surgery to change them out, but beggars n choosers n stuff...
It's got almost 385,000 kms on it and she purrs like a kitten and pulls like an ox. Not a puff of smoke, even when I'm hard on the throttle. Even despite being mildly upgraded with some go-fast injectors and an edge evolution tuner, it still blows nothing but hot air out the back.
A couple things the Duramax has that the 7.3 simply can't even get close to is (in my opinion) #1: fuel economy! I average about 18.5mpg Hwy in my 3500 Silverado Crew cab, long box, 4x4 dually (just sayin, it's a heavy ass truck).
My 7.3 tow truck drinks about 12 mpg on the hwy. It's not even close. In fact every 7.3 I've ever driven was a diesel pig, some worse than others. Had an old flatdeck F550 with a non turbo 7.3, and I tell you.. with your foot to the floor, 0 to 60 was probably about a minute, and worse with a concrete pump towing behind.
And the second thing I personally like about the D-max vs the 7.3 is.. (and I know it must be an illusion because I've seen the numbers).. I find the D-max has a longer torque curve. It keeps pulling hard no matter where the rpm's are. Whereas I find in my 7.3 that it's gutless above 2,000rpm. And I've driven several 7.3 tow trucks over many many years, so I'm not basing it off only 1 engine.
The 7.3 will pull anything, just not quickly.
The Duramax (older ones) will pull anything, and be quick about it. My vote for Best overall Diesel engine is split between the old 12valve Cummins units and the 1st gen D-max LB7.
Wow, I ended up writing a damn novel here. It's a slow night, I haven't had a tow in hours, so this happens.
If I would to get a 7.3, what years would you recommend and if I should get a F350 or F450? 🏁🤔🏁
When it comes to older auto transmissions. Just change the filter and fluid in the pan. Never do a flush idc even if its only got 20000kms or miles, Never flush it.
I change the filter and oil in the pan every 75000kms its a $50 service that's never failed me and my trans fluid has always been clean.
I would say for ultimate reliability and durability - the Gen 1 Dodge Ram Cummins would be my choice for most reliable. The Problem with newer diesels are two fold: Gov't emission regulations and customer power demands, both those are making the engineering process much more complex, which leads to less reliability (as it ages) and maintenance requirements throughout the ownership years.

The 12v is great if not the best diesel in trucks, but the truck it's sitting in is junk.

Hate to say it but 7.3 were built the best, stock 5.9 can certainly out pull a stock 7.3 but longevity the 7.3 takes the win.

Good video! This would have been a great video had they talked more about modern day diesels. What combination of engine & transmission? Then separate that answer to which transmission is the most reliable. When/how to service transmission? Which of the big three manufacturers have the best warranty to go with the truck? Which of the big three manufacturers have the best extended warranty if they offer one and is it worth it? what have they found to be the best oil to run in these engines especially in cold climates? Additives? How often should you change the engine oil? Filters?

Ask gale banks hes been tearing apart diesels for over 40 years.
He recommends duramax. They have always use the displacement of 6.6 liters. And manage to still crank out more horsepower and torque every year without changing the displacement. Cummins and powerstrokes have different displacements. Also you cannot beat isuzu and the chineese at building diesels

@@RemingtonScarboroughWhat year is the 7.3 and is it a F250 or F350?
The problem with the Cummins is the truck that it sits in. That truck is hands down the most unreliable of the big three.
…especially the bandaided minivan transmission sitting behind it.
Depends on what year I guess? I have a 2006 with 525,000 miles, and I still drive it. I did have the transmission rebuilt at 325,000. I don't know what more a guy could ask for?
@@DavidKroffCongrats on being an outlier.
@@SuperSnakePlissken I don't know about that. I own a construction company. I've had a lot of trucks. Never had a problem with Dodge trucks. Sorry you can't handle the truth.
@@DavidKroffCount your blessings that you are an outlier.
The main issues around the cummins have started with bad decisions with dodge. The common issues are 1. Killer Dowel pin, 2. Cheaped out on 1 piece exhaust manifold, 3. poor fuel supply lift pumps, 4. Grid heater bolt failure Every Generation of engine has had their issues. They are great engines no engine is perfect.
12 valve Cummins hands down, I’ve had them all😂 Simplicity equals reliability
7.3 reliable but heavy (off road) starters terrible changed so many I got to where I could do in less than 15 minutes on side of road.
I also run two stroke motor oil in my fuel every other fuel tank on my 24 valve Cummins 05 model
What people do not get is that the more power the engine creates the less reliable its gonna be. Its a lot of stress on the engines to create that power where the 7.3l didn't which is why it was more reliable. Go take a 7.3l make it high output, but 100s oof thounds of miles.on it and make millions of them. You will not hear everyone saying its the more reliable anymore.
So I bought a new F-250 in 1985 and I had the 6.9 , do you ever see those motors anymore? My understanding is the 7.3 was a bored out 6.9. For small diesels you can’t go wrong with a International. International used to build a diesel DT466 for medium duty trucks and it was a work horse you just couldn’t kill it. It was just a great engine.
😂🤣😂🤣 at 3:40 the guy walking into the frame then backing out with the awkward face 😅😅
I think they're going to really come down to if they're modded, and if so, how much. Mild mods are probably okay, but anything more will take its toll.
Not so much "reliable" but "robust" might help as all of these items require servicing so those that are built truly like a truck that is a lot more than engine and powertrain although absolutely spot on there is that. My take is "Dodge is getting there" the only true disaster in big trucks in 1990s so they still remain at the bottom even today. GM did go BK and worse than that needed a bailout (same true of Chrysler tho why this happened to Chrysler I have no idea...twice now actually) so that leaves Ford which was nearly felled by the Ford Explorer Firestone tire disaster but seems to have very much learned from that. Tesla is definitely making noise now tho and this has helped out *ALL* buyers in the entire Industry excepting...incredibly...Toyota the one and only Best Of in this 3 threesome until now today.
I'll stick to my 12 valve Cummins 5.9 since the V8 Diesels I had really sucked!
My 6.0 went 434k miles.. You have to spend some money to bulletproof, but once you do, its good..
egr kills engines, carbon. little diamonds in your cylinder. Old Cummins 12 and 24 P pumps. 100k rack. 12,000-mile service. on road! not you're going to work 12 miles and to the store. Diesels need highway running to maintain heat and running clean. Power increases kill the longevity of the engine and drivetrain. Transmissions. 46re 47re. 60k fluid filter, band adjustment. never flush. 400k 500k easy pulling trailers. 24 valve with vp44 pump replace supply pump with a fass pump. Cummins replaced Ford and GM here.
TURBOS?! 2016 F350 65K on my 3RD Turbo. First one under warranty at 44K second one 64K basically same fault with the impeller.
Ask questions about the trucks being sold now. It hard to find the older trucks for sale
Fords 6.7 had less warranty claims
The only diesel engine on the market for these pickup trucks that's an actual truck type engine is the Cummins flip the hood on any 18-wheeler and you're only going to see one type of engine inline 6 cylinder Cummins is the only one that makes that engine
That’s actually a myth about servicing the transmission. You won’t have so much debris and or a clogged filter from servicing the unit. This guy has no idea what he’s talking about. A new filter will capture all of the “debris”. The smallest debris can cause problems and if there were debris in a trans it would cause issues quickly
ford didn't make the mistake of moving to the 6.0, the EPA made that mistake for them as the 7.3 couldn't keep up with the tighter emissions standards. the 6.0 and 6.4 never got a chance to shine as uncle sam broke them before they were even born. their emissions controls systems were their biggest down fall, if not for EGR and DPF these engines actually wouldn't have been half bad. in terms of long block design the 6.0 was short some head studs making back pressure more problemmatic for the head gaskets. the 6.4 was built like a tank, it had potential to be great but it wasn't all good. while most of the engine is very tough it's biggest weakness was it's soft pistons which might have actually been fine if not for the DPF system. the regens raised the EGTs to a point that it stressed the weakness of these pistons and cracked them which resulted in recalls that navistar refused to fulfil and one diesel engine failure after another pissed off ford breaking their partnership with international. the 4th gen power stroke engine made by ford called the scorpion, is actually a great engine even with it being all corked up that thing is a monster.
How many more 6.7 are sold vs the others?
I got me a wonderful 1992, pre computer cummins 5.9 that works amazing.
7.3l powerstoke. Will run on a gal of oil easy to work on.
Any diesel engine that is taken care of and not abused will last a long time. Any diesel with power adders and abused, as well as, inefficient tunes will have issues.
The fact they never even mention a 5.9 L Cummins means they never see them, speaks volumes.
I didn't expect to here anything but power stroke engine being the most reliable on The Powerstroke Central UA-cam channel
Ford 7.3 power stroke I have a 1999 F350 still drive it today I don’t give a shit what anybody says absolute workhorse I wouldn’t trade it for any Duramax or Cummins out there
That’s great guys,I agree that the 7.3 diesel is a great engine,but it hasn’t been used since2003. I would like to know what is the most reliable diesel engine that is used now,like maybe in the past 5 years.
07 Dodge RAM 6 speed manual Cummins Megacab would be a dream truck
Guys they are not necessarily wrong saying the 7.3 is the most reliable diesel engine, it’s simply because they have never seen a 12 valve in their shop, they don’t break so they don’t even know it exists.
Never once did I hear anything about the 5.9 Cummins…. Only talked about the new ones… 5.9 12v and 24v are just as or more reliable than the 7.3. Hands down.
All engines have some sort of issues. I know for a fact that most diesel shops will tell you that they would be out business if it wasn't for power stroke or duramax
Sorry I have to disagree the 7.3 is a great engine but the older 12v Cummins is my absolute favorite motor my last one was still running strong at 350k
