Here is my list of alt fuels to try:
100% vegetable oil
50/50 diesel/waste motor oil
4:1 waste motor oil:gasoline
100% waste motor oil
100% new motor oil
100% ATF (new or used)
100% kerosene
100% Howes fuel treatment
Thanks for typing all my recommendations so I don’t have to lol. 👍
I agree he recommended all the things I would have and a couple more too.
@@Lowry7724
Covers my list
would also like to see regular gasoline with 0.5% two stroke oil premix (to provide lubrication for the hp pump) and also 10/90 gasoline/diesel (supossedly the octane of gas will delay ignition, wich in theory alows the fuel to mix with the air better)
I'll add a few more:
Alcohol/ethanol.
Natural gas.
Trash fumes.
Excrement fumes.
Old tyre oil extraction.
Plastic recycling.
Jimbo says "our little Honda Insight ONLY gets 71 mpg". Yes Jimbo, ONLY. LMAO 🤣🤣🤣
If 71mpg was constant, Jimbo would need 11 gal to make it comfortably to the Gulf of Mexico's beach.
Exactly... and we only have a 10 gallon fuel tank....
Fffffffffffffffffffffffff
Flexing.....
Only 2.5X what i get doing 55 mph in my automatic escort.
Back in the 80's, the State of Missouri commissioned my Dad to convert 3 vehicles to "alternate energy sources that could be produced within the State"
Dad converted a state owned 84 Malibu to run on assorted mixtures of Gas/Ethanol, a 1982 Chev Luv (quite a few of those available at a discount when the S-10 came out) for diesel, and a already converted Ford Ranger for electric.
Once the State was done with their testing, they offered him his choice of the vehicles- he took the Luv.
Drove it for 12 years on pretty much everything except diesel.
Id love to have a diesel Luv
My first vehicle was a ‘82 diesel Chevy LUV. I used to joke that the only actual Chevy part was the tailgate, as the truck was actually made by Isuzu. I got offers nearly every day from people who wanted to buy it. My dad ended up driving it well into the 2010s, believe it or not.
I collect Waste Veggie-Oil from a local restaurant in it’s original 4.6 gallon jug. I let it settle for 2 weeks, after which I drill a small hole just above the water and food level. The clear liquid drains into a 6 gallon bucket that we get from a pool and spa company for free. On top of the bucket I have a 400, 200, 100 and 75 micron polyester filters. I then pore the clean oil into a 30 gallon container and add 10% Gasoline to it. Using a small 12 volt gear pump from Seaflo, the clean oil is pumped through a 20, 5 and 1 micron polyester pleated and cleanable whole house filter into a 275 gallon IBC Tote. Using the same pump I draw out the desired amount and add more gasoline as needed according to the outside temperature. In order to use waste Veggie-Oil it must be blended with a solvent to reduce its viscosity to equal that of Diesel fuel. The colder the ambient temperature the more solvent is needed to prevent jelling of the fuel.
• 10% of Gasoline is good for temperatures above 80 degrees
• 15% of Gasoline is good for temperatures above 32 degrees
• 20% of Gasoline is good for temperatures below 32 degrees
• 30% of Gasoline is good for temperatures below 0 degrees
@stevenfrazier8939 Where would you recommend getting these types of filters from and do you struggle to clean them? Do they clog often? Any issues with water in the recovered oil? Thanks in advance for any insights you might offer.
That was pretty much how I did it when I ran my truck on Waste Veggie Oil. I used similar blends based on temps but I cut the WVO with diesel instead.
One thing you don't mention is bacteria and mold in the WVO. I had issues at some point and had to throw away over a hundred gallons and totally clean my storage. There are biocides to use that will prevent this (highly recommended). Clean, filtered oil is the ley however. No dirt, no water.
@@HyperSpaceProphet The gasoline seem to keep the oil from going off.
ooooooo, nice.
If you preheat the vegetable oil it lowers it's viscosity. I used a engine Volkwagen oil/coolant heat exchanger to heat the oil just before the injection pump.
Hiya, Jimbo.
A univercity in Poland did a research few years back, unused vegtable oil with 10% up to 30% of volumetric addition of gasoline gives almost the same physio-chemical properties as a regular diesel.
Rudolph Diesel, had designed his original diesel engine to run off of peanut oil.
Then went missing on a ship..
The highlight of my day, the next episode of Robot Cantina!
That and mustie1
My favorite thing about Sundays!
Agree!
Back about 15 years ago I had an old F250 with a naturally aspirated 7.3L diesel. I was working as a mechanic, full time, and would frequently dump old motor oil, transmission fluid, vegetable oil, etc into the tank (after filtering it) since it theoretically should have worked and it was a cheap old truck that I was willing to experiment with. The result was that the truck always ran perfect. I never filled the tank with 100% "other stuff", there was a always actual diesel fuel in the tank along with whatever I was adding to it. But, it ran perfect. Never had a single problem. No unusual starting, no changes in acceleration, no issues with letting it idle for long periods of time. I did that for years and had no problems at all. It ended up being something that I did without even thinking about it, and I just saw it as a convenient way to get rid of used oil/fluids while reducing my fuel bill.
Commenting before i watch. In my youth a friend of mine's father used to make his "own" fuel from all the restaurants used fryer oil. Usually they have to pay to get rid of it so he got it for free.
He had two large oil drums, with a pipe connecting the two, and a pump and filter mounted on the pipe. 2/4 Fryer oil went in one barrel, he then added 1/4 used engine oil to it and pumped the mix through the homemade filter box into the other barrel, where he then poured in 1/4 aviation kerosene. He claimed, that it in his old Mercedes 300d (123) it made the car accelerate harder and also run smoother with less smoke.
I still remember driving behind his car, and the exhaust coming from it smelling like french fries and gunsmoke. 😁
There's an awful lot of houses with tanks of #2 Fuel Oil on the way to the ocean as well. That stuff runs great in a diesel engine. Keep up the great videos.
Not on that part of the country - fuel oil heating is exceedingly rare in OK and TX.
Perhaps but he can tip off his tank and add a 5 gallon or two jerry cans from the last house with fuel oil.
My dad use to run used engine oil his his ford 1 ton truck. He had a filter setup that took all the carbon and any moisture out. He ran it for several years. My brother even started running it in his dodge pickup.
My uncle does this with his 2000 F250 diesel 7.3. He lives in Florida and the truck is still in great shape body wise.
@@Clearanceman2 I was gonna ask OP if it was a 7.3 but I figured it was. I've seen loads of folks doing that, they don't seem to care much 😂
I run my tractor on anywhere from 50/50 to straight waste oil. I get plenty of it from work and it makes my summer brush hogging pretty cheap 😂
Used engine oil is good for heating a work shop. I used to have a trucking company, and the used oil was used to heat the shop. The heater would burn about 1 gallon of used oil an hour. A lot of truck shops are saving used oil to heat their shops. Fairly cheap way to heat, and dispose of used oil.
Hey Jimbo! Love your work! Since german engineer Rudolf Diesel (1858-1913) built his first diesel engine in 1892. He experimented at first with a number of fuel sources including coal dust suspended in water however by the 1900 World's Fair in Paris, Dr Diesel had his engine running on 100 per cent peanut oil! Can you try with peanut oil to see if that realy works on todays engines? Thanks and keep up the great work!
Oh I would love to see the coal dust in water tested! There are a few of his original old single cyl diesels out there, would be a cool tribute to him.
If I remember correctly, Dr Diesel designed his engine specifically for farmers so that they could run their tractors on peanut oil that was grown on their own farms. Growing your own fuel must have been a boon to farmers back then. Probably still would be if farm vehicles weren’t so complex nowadays
Here in Oregon, a lot of hippies run their old diesel, Mercedes on vegetable oil, always been curious whether it’s worthwhile taking on such a project. Thanks Jimbo for doing the investigation.
It can be but there is a viscosity problem with the veggie oil. Most folks that didn't ruin their engine have a 2 tank setup where coolant warms the veggie oil. Start on diesel, switch over to veggie, 60 seconds before turning the engine off switch back to diesel. There is a lot of dewatering and filtering to go through when using waste vegetable oil too. For all the effort you might as well make biodiesel and not modify your vehicle.
@@Sygma6the old in-line diesel pump on Mercedes don’t need conversion, only issue is the viscosity of oil in cold climate, 2 tank systems is for modern engine.
1.9 TDi alh/asv with VE pump
You can run straight new vegetable Oil up to 10c :)
I run a quart of ATF to every tank of diesel (approximately 16 gallons for 82 GMC and 20 gallons for 94 F350). This is because they were built pre-ultra low sulfer and the mechanical injector pump and injectors need the additional lubrication and cleaning properties of the transmission fluid. It helps with mileage but I've always been a bit concerned about the EGT. I'd love to see you test it. Keep up the great work! P.S. I hope the Gnomes are staying warm.
ATF is a good idea. I am a fan of Marvel Mystery Oil for older engines.
I toss in used ATF or motor oil in each tank full of my Oldsmobile diesel. I usually just dump a whole 4-5qt jug in at fill up or half if I'm low on used oil somehow.
I'd use biodiesel or TC-W3 outboard oil for this, old sump oil is full of garbage you'd rather not run through the injectors (like water and carbon particles) and it burns dirty due to all the additives in it, to say nothing of the lead contamination from engine bearings etc.
A lot of diesel fuel already has 5% biodiesel added as a lubricity improver.
Side quest...build a cracking furnace(is it a furnace?) to turn plastic and other things into fuel.
Pyrolysis is the process of heating plastic in a low oxygen environment and then distilling the output gas as fuel. Apparently you can get fuel weights similar to propane, gasoline, diesel, etc.
I think its called a cracking distillery
Try rendered fat as a fuel! In a zombie apocalypse, there would be a lot of available sources of fat (pre-zombie humans?) that could be a readily available source of fuel as the vegetable oil dries up. Plus, it gives you something to have running up front of your makeshift shack/compound that will let passersby know that you're a source of fuel - you in a rocking chair in front of a fire, occasionally draining the rendered fat into a fuel tank of sorts. Plus an enormous barricade of zombies stacked up behind it.
animal fat would cause an algae. Semis get it from bio diesel since they removed sulfur .
If you have a supply of methanol and sodium hydroxide, animal fat can be used to make excellent biodiesel. The only downside is that it has a high gel point compared to vegetable biodiesel.
As far as I know, main problems with veg oil as diesel substitute are glycerin deposits and acid pH that may cause corrosion in long term. Also, they are not a great option when cold temperatures hit, bc they become very viscous. In that case, is good to start the engine with diesel and through a heat exchanger warm up the oil
Ooo, experiences from my youth coming back to be useful one more time! Back in the mid 90s, I was helping a friend convert a Merc 300D over to WVO, and we went through the whole process of scavenging from Chinese food shops (arguably the cleanest source compared to western fast food fryers), filtering and modifying the WVO to run in both summer and winter midwest environments. I have a notebook of our trials and tribulations musting away in a box somewhere, but going from memory, we had to dope up the WVO with 20% methanol to get it to run in winter reliably. At today's prices for methanol, I'd probably look into something cheaper like kerosene or even mineral spirits, but I don't have data for the percentages off hand. I bet if I could dig up my alt fuel book written in the 70s that we used for inspiration, it'd probably have some reference numbers. That's a log of digging that I'll save for apocalyptic conditions another day. 😁👍
Holy crap! I just made a post about my dad and I doing the same thing with a 300d! 15gal wvo, 1 gallon kerosene, and bottle of fuel stabilizer. Worked great! Like $10 for 16 gallon of fuel.
Edit: also I concur about the Chinese restaurants having much cleaner oil!
You can get a pulley that is bored to fit onto a taper bush of one of a number of standard sizes. Each size of taper bush is available in a wide range of inch and metric bores to accept the shaft. You only need an Allen key to tighten the assembly, and it will run perfectly true and will not fret, not even when it is on a single cylinder four-stroke diesel engine. With the same Allen key you can also easily loosen and remove the assembly.
If you want to make your engine last a lot longer cycle the crankcase oil through a filter . This increases oil capacity and keeps the splash fed Berings from the nasty contaminates ln these cheap Chinese engines .a small 12v pump is all that's required. Great work as always 👍
How would you do that? Draw oil from the drain, pump through filter, then return to engine via dipstick hole?
Any idea where he got the engine? Was it a one time thing or is someone selling them for that somewhere?
Because and effect - running from a zombie apocalypse, love how you brought that together Jimbo!
Last I checked (I run veg oil in my old Mercedes), the energy density of veg is about 10% less than diesel, so at your 50/50 mix you may notice a 5% difference in potential.
Diesel engines were originally ran on peanut/vegetable oil. So the results are no surprise.
These kinds of tests are something I plan on doing in the future. I really enjoy watching these videos.
There are an abundance of alternative fuels to test. Plus various additives and additions.
Keep up the great work Jimbo. May your shop be gnome free.
I love your videos man. I don’t know why exactly, but when Jimbo’s in the shop I gotta see what he’s doing! THANK for the entertainment!
Waste motor oil works really well in mechanically injected engines, drove one of my cars for a year on that stuff with no issues. Also ran jet a1 for a while with a tiny bit of oil mixed in to lubricate the pump. The engine ran a bit cooler and without any visible smoke whatsoever, while it smoked a bit on diesel. And yes, people actually use kerosene or jet fuel to cheat smog tests with old beat up diesel cars.
Depending on jet fuel, it can do a lot of damage to a diesel engine. For example, JP 4 will work pretty well IF you add some oil to it. JP 5,6,7 can work as well, I would not use JP8 that stuff will wipe out fuel injectors and fuel pumps very quickly.
@@bertgrau3934 I actually don't know much about jet fuels, just had access to some stuff that was drained out of commercial turboprop airliners during repairs and was supposed to be disposed of and it was tested and proven to work well in diesel engines lol. Old engines can run on almost anything for quite a while, but I wouldn't be so inclined to do such experiments on common rail stuff. Cheap disposable beaters are great for this reason
@@user-pz6tz9iq3w
Depends on which jet fuel it is, being from a turbo prop, I'm guessing it's aviation fuel which is more like gasoline. Wouldn't want to use straight in a diesel. Mix with oil and it would be OK.
When I was in the USAF, we had a couple of folks use jp-4 added to their diesel car. The fuel we drained from the fuel sumps, was just dumped into the car.
@@robertheinkel6225
As long as they didn't use a full tank of JP4 it would probably be OK.
I've heard this so many times but I'm not gonna risk my engine to test this and people I actually know never really try this. Thanks for testing this now I know
Its fine with full mechanical injection, but EFI diesels cant atomise it properly.
I have been running used Veg oil over 25 years. It works fine and people who say it does not are just doing it wrong and usually cutting corners. It has to be Clean 10 Um or under and DRY because Veg oil DOES hold water.
May be complicated but you can use natural gas with a 20% diesel for lubrication. There are engines that do this already.
This is such a feel good channel. Love watching it on my early weekends mornings to start the day with a smile!
I just ordered one of those tachs to adapt to my budget experimental 1987 diesel suburban. Thanks Jimbo for showing that. I had no idea they made something so cheap!
Right , I'm thinking about getting one just cuz I like the display of it and for the pric3 .. why not right 😅 peace and love bro
It's actually a great tach for the money, but my camera wont sync with the display.

@@robotcantina8957 Old filtered engine, gearbox, diff oil, brake fluid and at a push basic form of Hydrogen to extend the range in a Zombie Apocalypse... oh not forgetting gasoline vapers too... every option would be used...
@@mastercricket7626 I ran my 1.4 TDI VW polo and Isuzu 1.7 TDI GM/Vauxhall Cavalier on cooking oil....
Ran old Mecedes, Vokswagen and Volvo Diesels (mostly before Y2K models) without any issue on veggie oil. A bit harder to start in the winter, but once running no issues. More modern electronic/piezo injectors may behave differently, but the mechanical injectors ran ... and ran ... and ran.
I have done the same. Summer time 100%, winter time 70/30. On mechanical and early electronic, there are no problems whatsoever.
Wood gasification.
Jimbo for president 2024!
Man, that has to be some of the cheapest fun I've seen in a long time. It's far cheaper than my computer habit, grin, so good on you!.
If you want to experiment with diesel alternatives I would suggest actually getting a hold of some waste fry oil like you mentioned and see how difficult it is to filter it out effectively (after all you would need to find a good low tech solution to do so in the AI zombie apocalypse), I would also suggest doing the same with used motor oil, using different cutting additives like kerosene and gasoline, and even maybe find a way to measure the carbon output at the exhaust to measure the burn efficiency of the different fuels. Love your videos, always the highlight of my Sundays.
Diesel/used oil gets my vote. When i worked on generators in Iraq for KBR, we had to use a version of aviation fuel for the generators, as that's what they wanted us to use (easier for everything to use as few different fuels as possible) so we added used oil to the fuel tanks on the generators to add lubricity to the fuel to make it more like diesel. Diesel has paraffin in it, AVGas doesn't, and diesels don't like it as much
My understanding is Avgas is pretty dry, so that makes sense.
The old duece and a half's, most of them can run on just about anything, ive heard most of reasonable age will run on 1qt ATF to 1 gallon gasoline for a fair amount of time without causing damage.
The US military doesn't use much avgas, or gasoline in general. To simply logistics they try to run everything on jet fuel (kerosene, basically). Which is great if your daily driver is an Abrams tank, as they have a turbine engine anyway.
Diesels will run on kerosene but it's a poor lubricant for the fuel pump, so it would make sense to dose some kind of lubricaring additive. 2 stroke outboard oil or biodiesel would be my choices, and I'd put used sump oil right at the bottom of the list.
Waste vegetable oil (WVO) tank needs to be heated for optimum use... That's what I read on the Internet where they sale WVO kits. One needs to be concerned about the zombie apocalypse. I didn't know zombies don't like salt water. Learn something new today. Thank you for the video I like the intelligent content that keeps me thinking.
I drove a 1984 F250 with 6.9 diesel back and forth to college for 3 years on WMO (waste motor oil). It never missed a beat and I was driving 1000 miles a week for free. With five kids at home to feed it saved my bacon.
Thank you for your hard work. I really enjoy your content.
This is brilliant experimentation.
I remember reading about creating diesel substitute from (free ex-fastfood) used veg oil a few years back. other than purifying the oil the only vehicle issue i can recall was seals in some vehicles not compatible.
Not sure about their global policy but here in the UK McDonalds now keep their own used oil and get it converted into ecodiesel to power their delivery trucks.
Really love your channel, and love your format! Thank you and please continue with all your projects. 👍😃
Back when I owned a pre-smog Cummins 2500.... I would put EVERYTHING into it's fuel tank. But, because the factory lift pump was just a bad design... I had an air-dog on it with a large external filter. (Keeps junk out of the engine) But I would pour old fryer oil into it during the summer and it smelled great !!! (I would run it through a pre filter first and don't try it in the winter) I would also give my neighbors a fuel jug so when they would do oil changes... they could give me the waste oil. and... when I did a transmission service... I pored that directly into my tank. (I smelled bad) Basically... any oily thing I could get my hands on... and was clean-ish, would get used as free fuel. FYI... I sold the truck with 268K miles on it. The real pisser of all of this was... when we switched to ULSD fuel in 2007... I would have to put 2-stroke oil in "Real" diesel fuel to make sure my injector pump was properly lubed.
Thanks, that is an interesting thought, just add a two stroke oil as insurance.
There's a couple of fuels I'd like to see you try:
1) diesel with a 10% mix of methanol
2) ammonia
I've heard ammonia burns way cleaner since there's no carbon molecules in it. Just not sure on the purity of the mixture you're supposed to use. Great video Jimbo!! 💪🔥
You should do a dual fuel hybrid. Take an old diesel generator and hook it to your Prius and charge the battery pack on board. Essentially making a homebrew series hybrid vehicle.
Used motor oil. Set up with a basic fuel filter. Something cheap and easy to keep with the apocalypse theme
This channel absolutely just made my day. I was watching you guys all last night and watching videos on how to make black diesel/vegetable oil mixes. I was really thinking about doing something with a mini bike or go kart. Your the best
Thanks!
There is a guy that was putting used motor oil and cutting it with stale gasoline to use in his 5.9L Cummins. He gained something like 30 horsepower and added to his overall range. I think it was another 2-3mpg all told.
I don't know for sure, but I would imagine the fuel pump and injector make up the majority of the manufacturing cost of that engine
Especially considering that they both have tolerances that can be fractions of a thousandth of an inch
When teaching diesel engine troubleshooting and diagnostic at Key Power Tech Institute in Miami, I had a 3-71 Detroit Diesel engine connected to a generator. I put five gallon fuel tanks on it with a valve under each. I put diesel fuel, vegetable oil, 30w engine oil, canola oil and Peanut oil in each tank. Using a 55 gallon water tank, a three plate load system with a winch to lower it into the water and an amp gauge to tell hp the engine can produce! The most hp was produced with peanut oil and I believe it was 73.4 hp! The second highest was diesel fuel and third engine oil!
As some folks have already dropped in the comments, waste oil, or black diesel (used oil with some gasoline) would be neat to see.
Yeah, I read somewhere like 4 quarts WMO to 1 quart gasoline, or diesel...I got one of these motors...want to see if it will run for hours and hours before it kaputs
@@haydenc2742 Similar concepts here, my garage heater will run on diesel, but it would be cool to find a use for the 100 gallons of waste oil I have sitting around
Use gelatine to clarify waste oil
@@AlienLivesMatter I hadn't heard of that before, I'll have to look into it
Running a diesel on pure wood methanol would be interesting
Rudolph Diesel originally used vegetable oil because Diesel hadn't been invented, i used to burn a mix of Central heating oil and 20/50 oil, mix it like a 2 stroke mix, 1 pint ( uk pInt 568mlof Engine oil in to 5gallons( UK gallons at 4.5 litres( 1000mml) and shake up, essentially a 40:1 mix ratio.
Yes! nobody worth their salt has done the "alternative diesel fuels" thing with the kind of thoroughness it deserves. Im glad I can anticipate some from you.
I keep looking for a use for one of these engines just to use all my waste oils. So I'd love to see used oil tested. Especially the new super thin synthetic stuff 0w20 0w10 etc
I have a suspicion that a diesel engine might not run on used synthetic lubricating oil. I once tried to spray some on the bottom of my van to try to protect it against rust, and the sprayer would not atomize the synthetic oil at all although it will spray mineral oil in a fine mist. I have also tried to use used synthetic oil to start a fire to burn garden waste, and the oil is very reluctant to ignite.
I've seen a guy on Tik Tok who teaches how to make something called black diesel, which consists of 4 gallons of waste oil (used motor oil) and 1 gallon regular unleaded gasoline. It would be interesting to see a test with this.
Correct. I run black diesel in my 2002 jetta tdi with the alh engine (the last easy accessible injector vw engine)
The car gets 35 mpg around town and 42 on the hwy. I've used it to tow several other vw and random cars back to my shop on a tow dolly. I'm currently swapping one of the extra tdi engines in to a ranger (pretty common swap in Canada)
Black diesel also runs well in my 12 valve 5.9 cummins bus. Currently running 70 percent blk diesel to 30 percent diesel.
Eventually I'll have a 2 tank system so I can do all my driving on blk diesel, then have the 2nd tank with the mix in it to simply clean the injectors to start and stop the engines
Another Great Video, Jimbo. I really appreciate the education that you provide. Looking forward to more tests with the little one lung diesel. Thanks
Thanks again!
When I was a teen (back in the 90's), there was a guy who would come to the restaurant that I worked at, to collect our old fry oil. He had a Chevy pickup with a Caterpillar diesel swap. I had a chat with him the one day, and he said he had multiple restaurants that he picked up from, and dropped off empty drums. He would filter out the debris, and do his magic (he told me, I can't remember), and then run it in his truck. It amazed me that our waste oil could fuel someone else's vehicle. I will say though, we swapped our oil every week like clockwork, so it was probably liquid gold
I'm still unsure what a Deezull engine is....
Humble suggestion. HHO generator added to the intake with the 50/50 diesel/Veg oil blend used as fuel.
I will loan the hho generator if RC would do it. Might take me a second to dig it out of storage. I would also like to see the exhaust used to generate steam, and then draft the steam into the engine, for comparison to HHO
We run our 5,000 watt Diesel generator on cleaned and blended Waste Veggie-Oil to charge our 28 kilowatt LiFePO4 battery bank when it is cloudy. Jimbo, I can share photos of our process if you are interested.
The trick to efficient use of vegetable oil is preheating the fuel to 220 degrees Fahrenheit before injection, I ran a 1984 bluebird school bus with a gm 8.4liter turbo diesel on waste vegetable oil for 8 years, the fuel was heated, filtered and had all moisture removed prior to use, then it was heated using inline electric heaters taking it to 220f right before the injection pump, this increases the engine efficiency dramatically and reduces the possibility of gelling of the fuel. Using electric solenoid valves on both the supply and return lines allow for switching from diesel to vegetable oil without the return dumping vegetable oil into the diesel tank. Using the coolant system of the engine to heat the vegetable oil holding tank allows you to start the engine on diesel, warm it up, then switch to vegetable oil after about 5 minutes without the viscosity of the vegetable oil causing problems. Also filtering the heated vegetable oil through a 5 micron water lock filter before its put into the holding tank keeps the injectors from clogging.
Thanks Jimbo! Stay warm down there!
I’ve been running my diesels on everything except 100% diesel. Filtration is the key! I use fry oils, used engine oil, trans fluids. (Conventional burn cleaner than synthetics) you can occasionally get contaminated Jet-A, kerosene, hydraulic fluid etc. All are filtered and then blended with diesel. You can run on 100% fry oil, oil or Jet-A, but the engine oil at 100% is a little smokie. Axle grease needs to be thinned a lot before it will run properly, The veg oil in the winter at 100% is harder to start, Jet-A is similar to diesel but has less lubricant in it. Although the military diesels all run on JP-8 (kin to jet-a) they don’t seem to care about less lubricant in the fuel. I tend to keep gasoline away from my diesels. When Rudolph Diesel invented the darn engine, diesel fuel didn’t exist. It was invented to run on oils of sorts. I’m eager to see what kind of slurry you’re gonna come up with to feed this thing.
Very interesting! I’m looking forward to the next episode. Until then I will ride my bicycle… Thanks for the Diesel show! Cheers - Martin/Germany
I ran WVO in my 82 mb 300cd, and a Greasecar Kit in a f250 power stroke. Over 15,000 miles on the powerstroke. 5%unleaded gas, 10% diesel fuel, 85% Used cooking oil from restaurants...
😅 The secret is to get the wvo close to the same viscosity os diesel by heating it.
This channel is my zombie apocalypse tutorial. Not IF, but WHEN 😁
Great video as always. Love the little diesel engine. A struggle to find something like that cheap here in the UK. I used to run vegetable oil pure in my old diesel landrover as it was cheaper than diesel at the time but not anymore. I have used old engine oil, power steering fluid, gearbox oil, brake fluid. Run perfectly fine in the indirect injection engine.
This was a little differnt but AWESOME stuff Jimbo! Like most of your videos, I learned something!
Hey there Jimbo! It’s been a while, but I’ve returned to throw in my two cents.
1¢) Highway diesel here in the states is all ultra low sulphur meaning the fuel has a lower acidity but also a higher friction coefficient.
2¢) The vegetable oil has much longer polymer bonds than the diesel making it more viscous (potentially clogging injectors), but also greatly reducing the friction coefficient.
Free tertiary cent!) I wouldn’t recommend going over 50/50 mix of uncooked veg oil, but 30/70 is plenty safe. You can use a solvent to cut through the polymer bonds of high viscosity fuels, but maybe start with a 10:1 mix to stay on the safe side.
Good luck on your future diesel experiments! I’ll catch up with your videos soon.
During the 1980-90 Mercedes put out a bulletin,that if you could not buy winterdiesel, you could mix your own, by adding gasoline up to 50/50 mix was allowed, would be funto see how many BTU you could get from that ??????????????
Great stuff! Those little 196cc diesels are perfect to experiment with! Love this video Jimbo!
Thanks! 👍
so i have a few old W124 Mercedes a 4cyl 200D 875,000km a 5 cyl 250D 574,000km and a 300D for spares
so this old 200D is slow as hell but i loved it anyway , but here in Denmark you pay 800$ per year in roadtax alone , so when the diesel was high i just when to the supermarket and purchased their sun slower and rapseed oil on sale for nearly half the prize , it ran great on it , in the winter i had to mix 5% gasoline in the seedoil ,,i i also ran alot of filtered used motor and gear oil but for that one had to mix in atleast 25% diesel and 5% gas ,,,,
please be aware that this was a mekanical fuel pump , and i always had a extra filter and a fresh battery in the trunk and had spares so i could at no cost replace injectors if needed,,newer diesel cars do not try,,,
Been running my Mercedes 300D on waste veggie oil, used motor oil, used trans fluid, and mixes for years. 806,600 miles and still going.
i love your content, you do whatever you feel like to do in an interesting way !
Love that you are playing around with one of these cheap Chinese diesels. I have one that i'm building a little 400 watt generator from but need to keep it at constant RPM for frequency stability.
I purchased one of them there little diesel engines for a back up generator. Thanks for the test run. Oh when diesel was 1st designed it was meant to run on vegetable oil.
You make me look forward to sundays again!!
Love your experiments....one complaint ...i wish your episode were longer !! : )
Oh….1am here and was going to go to bed then you showed up…..thanks😊
Where was it 1am ar 08:05 CST?

My guess is, the best. Also, I wanted to note that I just realized that it's Sunday and that means a new Robot Cantina video, so I immediately came here to watch it. Yes, I am that nerdy.
I enjoy your content, been watching since the original 212cc swap.
I appreciate that!
Definitely luvin ur diesel fuel experiments, especially considering I make alternative diesel fuel from veggie oil.
Keep'r goin, Jimbo.
Pretty cool
later on, add a little propane or map gas injection. keep up the good work Jimbo!
Here in Spain we have a lot of small diesel cars and this is doable with the older ones, I mean, the ones that use mechanic pumps. I have a 1994 Seat Ibiza (this is the Spanish version of the VW Polo, just a bit smaller than a Golf) that would work with 100% vegetable oil no problem (main issue would be the cold starts) as the 1.9 litre n/a diesel (producing a whooping 68 bhp) uses a mechanical pump. Well, there's another issue: tax evasion. Fuel here is really expensive (and so is vegetable oil) as it is charged with plenty of taxes. So theoretically, if you are using oil as fuel, you are not paying oil taxes, hence you may get in trouble (well, if they find out). Great stuff as always Jimbo!
You did it! I feel so appreciated 😭 look into the process of refining the veggy oil for a better biodiesel
excellent stuff as usual Jim. one of the trains that engine is soooo cheap is the tolerances are really loose. what this means is that you have a huge variety of fuels that that engine will tolerate. preheated used engine oil run through a fairly low micron filter will run just fine. also on the menu are hydraulic oil, ATF, just about any kind of oil at the right viscosity. fun fact, Rudolph Diesel designed the engine to run on veg oil, peanut in particular.
Love this video! I’d love to see what this thing looks like inside!
That picture was on point 👍
Love your videos Jim. It would be interesting to see if you can run that engine totally off of vegetable without any diesel fuel assist. Might put a y fitting on your fuel line so all you have to do is switch from one fuel to the other. Thanks for all the great info and videos. 👍👍👍👍👍🍻🍻
I know there are a lot of people who know about what you are doing in your videos. But I don’t think any of them explained it as well as you do. I’ve been a car guy Spence I got my first peddle car. Your Chanel has started a new chapter in my car guy life. Thankyou so much! I’m also a Kansas guy. Olathe.🇺🇸👍🤪🍺
Thanks!
As far as energy content and generated HP is concerned, vegetable oil works just as well as diesel.
The problems with vegetable oil are mainly due to high fuel viscosity damaging the injection pump, and vegetable oil blow-by getting into the crankcase sump and contaminating the lubrication oil.
In other words for a reliable vegetable oil powered engine, you need to heat the fuel tank and fuel lines to keep the fuel thin, and replace the engine oil at slightly more frequent intervals than usual.
Of course, alternative methods of thinning the fuel work equally as well, like blending 50/50 as you have done in this video, or you can go down the transesterification route and create biodiesel.
You sir almost made me spit out my coffee with the meme images. Watt… lol.
This video is awesome. Do more like this!
Another great video, thanks for sharing 👍.
Thank you for your Videos! This little engine will run (I know for a fact) on almost everything that is like oil as long as it is liquid including waste oil.
That has been tested before.
Haven't seen somebody used butter before, I'm sure it will work as long as you head it up to become liquid, or bacon grease
Yah. New video from Jimbo. Love your work 👍
I used Sun flower Oil in my 50cc two stroke Puch Maxi, the cyl head was shaved by approx 1 mm.
The thing made insane high amount of rpm, the smell was like a restaurant.
3:18 That's a cool rig you got there.
This science fiction nerd loves the flying saucer noises that your Insight made in the opening seconds of your video.
Excited to see different fuel sources used. Please put in a valiant effort to filter anything that would be used. I understand that during such circumstances as a zombie apocalypse you might not have access to things like 1-2 micron filters and a pump or centrifugal filtering means but you can’t just dump it straight in.
Another common practice is to mix veg oil and gasoline to about 70/30, or 80/20, respectively. Generally dependent on the temperature. The gas helps thin the veg oil to diesel viscosity and can help in burning the glycerin in the veg oil.
I'm pretty sure it'd be better to use kerosene but of course kerosene costs more per gallon at the pump from most gas stations.
Robot cantina rocks! Great video thank you
Fun episode! Try wood tar. I’ve seen a video about getting oil from old tyres too.
