Anyone who's witnessed a diesel runaway knows very well that diesels run great on motor oil.

Hearsay. I but you know not a single person who ever was at a diesel runaway. They are possible but very, very unlikely. It's a nightmare tale invented by the US petrol assoc.
@ not at all. Diesels don't have a throttle like a gasoline engine. So if you have an outside fuel source being sucked into the intake (flammable vapors, oil leaking into the turbo air intake side, etc) you can't control it, and the engine will run away unless you choke the air.
@@kyletrummel69 That's why all USMC motorpool NCOs are required to carry a clipboard at all times. They fit flush up against all sealed air intake tubes as demonstrated day one on the job for all newbies and again throughout most field days on ready line. Semper Fi!!
@ It's not hard to use preventative measures to ensure that it doesn't happen, but to say it's 'very, very unlikely' and a 'nightmare tale invented by the US petrol assoc" is grossly misinformed my friend.
@ happened to me once. It was the first startup after a friend of mine turboed his Detroit 6.2. The whole deal lasted for around two and a half seconds. I told him to hold a small wooden board right next to the air intake just incase. And wouldn't you know it, after five very hard knocks, it ran away. The engine was toast afterwards
As far as I understand the diesel motor was originally designed to run on various vegetable based oils. Petroleum oils was not the diesels first intended oil to burn
@@olfreal No. Diesel was a waste product of cracking oil and producing petrol (gasoline) The refineries had no use for diesel... until they realised it could be used as a fuel in "diesel" engines.... The rest is history.
About 20 years ago I had a friend who had a roughly 150 mile return commute every day. He bought a Citroen AX 1.5 Diesel for this commute. Now for anyone not European these were a very small, very light, very economical car that could do well over 80mpg in the right conditions. He got waste cooking oil from his local chip shop and refined it for use in the Citroen. The company he worked for gave him a travel allowance of £300 every week so he basically got this all into his pocket
I HAD A FRIEND WHO WAS A MECHANIC WHO OWNED AN OLD PEUGEOT GOT OIL FROM THE FROM FISH AND CHIP SHOP AND PUT THROUGH A FILTER PAPER AND THE SAME WITH WAST OIL FROM SERVICING CARS DID IT FOR YEARS. CANNOT DO IT ON MODERN CARS DUE TO DAMAGING HIGH PRESSURE FUEL PUMP AND THE SEALS..
Rudolph diesel originally designed and intended for his engine to run on peanut oil I believe. You can run diesels with an older style non high pressure common rail system on pretty much anything flammable. The ldt 465 multifuel will run on pretty much anything including gasoline.
My 1.9 alh diesel would run on anything . Its own oil changes, gear oil, i got two 55 gallon drums of waste machine oil, a little atf, extreme ammounts of additives like Marvel Mystery Oil, it did not care . It was modified to have over double the stock power and I drove it hard . Those old diesels were industructable . I ended up selling the car with 302k miles still going strong.
He originally intended his engine to run on coal dust, but that didn’t work well. Caterpillar originally marketed their diesel as a multi fuel engine, I remember reading an old ad of theirs talking about a soybean farm, that ran all of their tractors on soybean oil.
Feb 21, 2019 - The Diesel-Engine was originally made to run on HEMP-OIL ! In 1893, German inventor Rudolph Diesel published a paper entitled "The Theory ...
@@jusportel fist diesel run on coal dust but this wear the engine very fast (abrasive dust in the smoke), this explain why this was not use...In Europe the most use vegetable oil was rapseed oil because it's the fluidest and the cheapest...
Diesel motors are truly my favorite engines. They are so diverse and reliable and can run on almost anything. As long as they are pure engines and not tampered with by green weenies.
@@wadebrewer7212 its an environmental thing, its the same with any other crude oil based engines i.e spark ignition engines, jet engines. its not just diesels. but 100% diesels are so much more reliable and with a much larger fuel efficiency
I knew the heating oil would work. Had a friend that bought a house in the mid 2000s and their was two 1,000 gallon heating oil tanks full on his property that he wanted gone. I had an old F350 with the 7.3L IDI engine in it. I ran almost 2,000 gallons of the stuff through it with no issues. I was nice not having a fuel bill for a while.
It is illegal to do so in us as it is Red colored and had no tax paid on it . Home heating oil is sane as diesel except the Cetane is not checked . Off road diesel for tractors for example is red. If they find the dye in your fuel filter you are in trouble…
I mean, heating oil is basically red diesel which is a diesel fuel that doesn't have huge tax on them and usually been colored red so only farm equipment able to use them, you pretty lucky law enforcement doesn't pull you over and fine you because you use red diesel
You shouldn’t let it go to waste but you can’t Legally use it on Road. Sell to farmer , use in generators , Front end loaders etc. I worked on a harbor tug 35 years ago and every crew member but me had a diesel car or truck…. Just warning people what the law is, take your chances if you must, but know.
@@josephpadula2283 One of my old bosses was a truck driver owner operator 47 years experience. He was starting out just as WWII ended. He told me truck drivers were caught cheating by the Ministry back then. It was Blue dye and would create a blue haze on the engine as it's running. Big fines. I remember him saying anything more than a couple shot glasses worth dumped in and it would show up and that was in the 40s. We ran his Drott shovel on Boiler Oil many times he said the ash was dry vs Diesel oil otherwise it's identical. Can't use Bunker Oil unless you pre heat to 350F if I remember right. Impossible to wash off if you get it on something it's coal black. We had about a drum worth of the stuff from a scrapped Freighter.
The original Rudolf Diesel prototype actually ran on coal dust. It exploded. The inventor designed the revision to run on anything combustible that could be sprayed into the cylinders. Be aware, however, that there is a certain amount of lubricity required in the fuel for upper cylinder longevity that may not be present in the oils used here. As others have stated, power level is unknown without load testing.
vegetable oils are fine to run in this, just flush with diesel fuel for a few min before shutting down. Not sure the ATF was a great idea though ... the pump might not have liked that one very much.
@@detaart iv run small amounts of ATF in my 5.9 Cummins with no issues. I would NOT recommend it nowadays however as most ATF fluids have friction modifiers intended for clutch packs and would probably destroy a P-Pump or sand blast the top of your cylinder head. My best guess anyways.
I have an old ('95) BMW turbodiesel, and as an experiment I ran it on Sunflower oil & Rapeseed oil earlier this year, with a bit of petrol thrown in to thin the cooking oils a bit. Ran perfectly. Smelled like a chip shop too, which was nice. It also got a mix of ATF and standard paint thinners (50%/50% toluene/xylene) mixed in with diesel to clean out the injectors. I had an old Transit van with a 2.5L non-turbo diesel which would run on almost anything. - Went to watch drag racing in it once, and drove 145 miles home on all the cooking oil people had left behind after the weekend's racing. Mix of all sorts. The Transit also got old engine oil chucked into ithe fuel tank occasionally. It didn't mind that either.
I recall a long term test of sunflower oil in a diesel back in the early 80s , the tank started to collect a heavy slug. A result of the heating and reheating the oil in the return line. BTW, there are diesels out in the oil fields that run on just filtered crude oil.
Near where I live there are 3 diesel engines that run on crude oil, they are 3 stories high and generate electricity for the grid. 2 are 65,000 HP and one is 100,000 HP.
I was on a cross country trip and rode through an oil field... there were single cylinder diesels (looked like the old hit and miss engines) that look like they were built in the early 1900's... just chugging along.
Cub Cadet compact loader tractors new lititure said it had a Cat diesel but had a Perkins id an tag . CubCadet no longer has compact diesel tractors (makes) they had issues stay clear
I'm from Indonesia and have been using a mixture of cooking oil + engine oil for 6 years with a composition of 50:50, and have never had a problem until now. the engine sound becomes smoother and more powerful In my country many people have used it for years😁😁
In Europe it is only allowed to use this in heaters. The red color indicates lower tax rate on this fuel. It also has other additives than diesel, which contains 7% biodiesel in Germany and has a cetan number of around 50. Heating oil is a little harder to ignite. This would not make any difference in mechanical controlled diesel engines but is an issue with modern injection systems.
Off road diesel is exactly the same as on road diesel, it's just dyed red because it's not taxed and allows DOT to see if drivers are using the right fuel.
Years back I had diesel car and the price of vegetable cooking oil was at an all time low. Half the price of diesel so I ran it on the veg oil. Thing is it smelt like I was frying food but it ran great. Engine noise was almost zero with the heavier veg oil. Tappet noise was totally gone. It really did quieten everything a lot. No problems with starting it up etc.
It should be noted that, if you accidentally fill with gasoline instead of diesel, you can adjust the viscosity with mineral oil for the engine, if there is still room in the tank. The thicker the oil, the less oil is needed. And the viscosity of the fuel is necessary to prevent the high pressure pump from seizing. This way you can save the engine, and the day, without additional costs for emptying the tank in service. @Andrey, you can do the following experiment to see what is the percentage of oil plus gasoline to get the right viscosity, so as not to destroy the engine.
I had a 97 Ford F-350 that was my daily driver for 5 years using nothing but waste vegetable oil that I pumped out of oil dumpsters at the back of restaurants. I drove to mexico three times and all the way to Costa Rica and back. I’m sure I paid for the truck a few times over in fuel cost savings. It had a fuel filter that doubled as a heat exchanger using coolant from the engine, and a separate tank for oil that was also heated by coolant. No issues with reduced power at any time. Ran quieter due to better lubrication of the injectors. Truck started on diesel, then switched over to oil once engine heated up. Oil system and truck was working fine when I sold the truck about six years ago. No issues with clogging, etc.
In the 90s I ran my Land Rover discovery 200tdi on 20lts of cooking oil from Costco the 20ltr drum cost £9.99 I always had at least half a tank of diesel topped up with veg oil. The diesel engine ran quieter and pulled a bit harder but the only problem it did smell like cooking chips and if we went out in a group of off-roaders they asked me to be at the rear of the group to stop people feeling hungry. It did save me loads of money using the cooking oil.
I am just here thinking how cool it would be to swap this tiny Cat motor into my bike! Then I was thinking about how to hook it to the gearbox and adapt the clutch. I would definitely keep it yellow though.
It's nice test, tried just filtered used cooking oil in my 2013. diesel car. Because of the common rail I did it 50:50 with regular diesel. All good, no noticeable difference in driving. Just smelling like someone is frying something ;-) in my older one with "pumpe diese" or bosch mechanical pump I went 75:25 in favor of used cooking oil. The only thing to watch for is cold weather. It didn't start lightly as on diesel. So, definitely separate the reservoir and split the fuel system to start and stop the engine with diesel and run the mix through the heater coil when the engine is up the temp. Also, I would like to check for exhaust temps with each oil and clean engine sound without the music. Other than that, nice one!
For some equipment out on a Family Friends Farm we have a block warmer on the fuel tank and use old oil pumps to circulate the fuel. We use a mix of 50/50 used oil/diesel, engines don't seem to mind and they get regular maintenance too. Using the oil keeps down extra expenses on trying to send the oil to be recycled and on fuel costs.
Cool video, I had always heard this, but it was neat to see it. I will say that a diesel engine uses a high pressure pump that may wear out prematurely if you use an oil that does not lubricate as well as diesel. The fact that it burns and runs with no load is one thing, but it could be causing damage. Project farm does a lot of videos where he does basic film strength / lubricity testing, and it always surprises me how well some oils lubricate, so perhaps most or all of these would be fine.
My good friend was running his old diesel car on transformer oil for a long time(like 5-8 years) as he have been working in electricity and have big supply of used transformer oil.
@@MrActionPL1 I don't know what country you are in, and I might be wrong with this information, but you may not want to share that information. I was under the impression that transformer oil was full of PCBs and is highly toxic and cancer causing. From what I recall, there was a lot of talk about PCBs in the late 80s through the 90s and I feel like burning that oil in a car would be pumping that stuff into the air and probably very much frowned upon / illegal / hazardous... Maybe I'm missing something, but those are my thoughts on that.
In Houston it was a Hurricane that changed everyday life , no fuel for gas stations during a week of plants recovering the flooding . I had a W123 Mercedes and recovered used 55 gallons of veggie oil sitting for a few months . It’s a micron sock filter you pump the oil through then make it thinner with other mixtures added to get a desired batch . Different straight tank runs are out their to explore . My week of needed reserves did the trick , was able to get through the event , the w123 617 didn’t skip a beat .
This is a fairly simple engine so it will run on almost everything. The much more specialized new car engines with tons of sensors, turbo, more advanced injection, particle filters and stuff, will begin to have problems with different fuels like these.
@@CaptHollister It is more of a cover own ass. Other fuels might require other oil change intervals or different performance in cold or warm weather. Mixing fuels also makes it a bit tricky to guess what happens in the tank and hoses. My lawnmover forbids any blend of ethanol fuel, but it is pretty much impossible to buy gasoline without ethanol here, so I have to ignore that requirement.
I ran an old International 414 tractor on mineral oil I salvaged from a used hydro transformer. Used quick start to help it start in the cold and it ran very well.
@@machew2009 Correct, that is Caterpillars designation for this Perkins engine. Perkins has been a subsidiary of Cat for over 20 years… (Cat engines smaller than about 200 horsepower are made by Perkins)
Great experiment. I mis old transformer mineral oil 50/50 with diesel in our old Nissan diesel car and in the lister diesel generator with no problems at all.
Thank you so much for showing us people to reuse waste oil in either your car or heating your hot water an your home at same time , just make sure you filter dirty oils with a paint strainer an the a funnel with cardboard tubes filled with toilet paper set this up over clean bottle or bucket because it takes time to pass through toilet paper but once its through paper its clean an safe for most diesel engines to use , but regularly run plash of diesel through tank just to prevent sludging or gelling of the fuel lines an injector pump an injectors , this will or should give you reliable service , and for sake of 30 40 dollars replace fuel filters say every 150 200 hours , used cooking oil can be picked up for free by 44 gallon drum at takeaway food stores just go ask them 1st , 9/10 they will be glad to have you take it for free ,, cost them money to have it taken away
The catch or downside is the chimney will become oily dirty and difficult to clean later. In a vehicle the vegetable oil cause a gum to form and create a type of fungus. I'm not expert just relating what I learned from furnace and truck mechanics over the years. I would put some small amount in with the correct fuel rather than entirely different thing daily.
The only issue with diesels running wacky fuels is you need to make sure you either add a lubricant to the fuel (kerosene needs an additive for example) or the fuel you use needs to be a lubricant itself. You run the risk of ruining the engine otherwise, thick oils also need thinning in colder climates otherwise it'll just jell
You won't damage the pump or injectors on the old style diesels withe these different oils because the have more lubricity than the new diesel fuel. As for gelling in the winter need a warmer in the tank.
Thank you for the video. Would love to see you build a load tester and do some more scientific testing with fuel consumption and temperatures recorded. Thanks!
Diesel and heating oil are pretty similar; the main difference being in taxes paid for diesel vs heating oil. The second difference is the wax contents; never try to run heating oil in a vehicle in winter, it will haze and turn to gel due to it's high paraffin contents. AFAIK sulphur contents is now very low in both fuels.
YES diesels will run on vegetable oil. We can go all the way back to ww2, diesel was scarce in many parts of Europe during the war, military vehicles such as trucks and tanks would use vegetable oil since vegetable oil was a little easier to get even used cooking vegetable oil was used, the only problem was it would often freeze when the temperature drop below the freezing mark, so often it was mixed with some alcohol to help prevent the vegetable oil from freezing in the lines during winter. true facts :)
Cool video ! I’d imagine most any type of fluid that has some sort of oil base will work on an mechanical style diesel pump engine! Could always dilute some of the thicker oils with diesel fuel if the viscosity is too thick! Freezing temps would be the only factor imo of using other oils as fuel!
The cold will prevent starting Some of the oils here will solidify and therefore can’t be pumped at colder temperatures … It’s the triglycerides that are in some oils that turn solid with cold
It is also about deposits on the cylinder head and lubrication. Multi-fuel engines like the Leopard 2's diesel eat basically anything that burns and can be pumped. However, it is stipulated that about 60% of the fuel used should be diesel in order to maintain the durability of the engine. The rest can be basically any flammable liquid, alcohol, kerosene, oil (vegetable, animal or earth), gasoline... . However, no liquid containing water should be filled in, since water is not compressible and can thus destroy the motor.
I know you said you can't do any load testing, but that's really the only way to know for sure. I don't think it's fair to say those liquids were comparable as fuel after this test, only that they all succeeded in keeping the engine running at idle
You can compare the energy density of the different oils and have a good expectation of the change in power output. I run used motor oil in my tractor.
Yes it'll run on cooking oil, but cooling oil lacks the lubricity to lubricate the pump and injectors as well as the viscosity being so thick it can damage parts. Also the oil will break down rubber, this means rubber hoses, o-rings, etc.. Technically a diesel will run on any oil based lubricant, or oil substance. How well it will run and how long it'll last will vary.
This was fun to watch, any kind of vegetable or petrolem based oil can run fine through a diesel in theory, but some are better than others when the ambient air temperature is low.
On the older diesels not designed for ultra low sulfur diesel fuel it was common practice for a lot of guys to buy a small bottle of ATF and mix it in with every fill up.
You would actually be better off turning those vegetable based oils into propper transesterified bio-diesel. Which is a mono-gliceride fuel. If you run any form of tri-gliceride vegetable oil in a diesel engine you will soon wear the motor out as well as clogging lines injectors and filters with gum and acids, the more used the oil the higher the acidity and all vegetable oils are acidic and need to be PH balanced. I ran my Nissan on biodiesel for the 7 years I had it and no major dramas. The motor was an LD 20. Ran better on Bio than regular. But would drink more.
Great information. It is a blessing that we share our knowledge with each other. I am interested in diesel engine technology in order to set up my own independent systems .
@@patrickjohnson2225 like with running a petrol/gasoline motor on alcohol or propane or Natural gas. Tuning it with appropriate timing etc also works wonders. Takes a little more energy to fire Bio diesel, but it burns a bit faster because of the natural nitrous oxide in the oil.
You should monitor temps as well. You will see more of a difference in the fuels based on temp rather than RPM. Also running at idle vs under load will yeild different results. An engine may idle well but wont neccesarily rev up well.
When we changed our fuel filters on a 425hp Caterpillar engine, we always filled the new canister filter with automatic transmission fluid to avoid getting the fuel system air-locked. They run perfectly on ATF.
other things to try. 1. running it on heating fuel, k1 fuel for space heaters and model fuel (the clear alcohol like fuel used in rc engines) 2. run rc engines from diesel, heating fuel and k1. i think you can put the engine under load if the alternator is still on it you can wire up the alternator to be able to charge the battery and then short the output of the alternator that should put enough of a load.
@@josephpadula2283 the engine probably was pulled from a junk yard machine that was probably involved in car crash or was the result of a manufacturer refusal to repair a machine someone tried to repair by hacking the brain box due to the anti right to repair. plus you could buy a new fuel pump at your auto parts store as well as a new alternator. as for the costs you can get that paid by cashing out some of your videos. if you dont want to sacrifice the fuel pump you can go to your auto parts store and buy a cheap diesel pump for a vw car that was involved in the cheat scandal and if you dont want to sacrifice the alternator you can buy one at an auto parts store or even go to a junk yard.
You should know, I live in Indonesia, I use crude palm oil (CPO) to fuel my truck, which loads at least 80 tons more palm oil to the mill. This is very damaging because crude palm oil has a lot of residue, I modified the fuel filter and increased the speed of the fuel pump.
Great video... Just don't let the engine stand for more then 6 hours with any oil other then diesel fuel. Otherwise growth and geling can happen causing internal problems. Heat the oil to 100 degrees Fahrenheit. Run a dual tank system to start/stop engine on diesel fuel esp in colder temperatures.
When I worked for a Cat dealer (H.O.Penn) I used a container that was to have diesel fuel in it, instead it had new 15W40 oil. It ran fine, it was a 3406B engine.
As diesels are governed engines, I am not surprised that the RPM's were pretty consistent no matter what the little motor was burning. What would have been more interesting is the change in throttle position.
Most likely made by Shibara or Perkins. Caterpillar owns both of those companies and puts those engines in their construction equipment, hence the yellow paint and cat branding.
Interesting results. On a side note. Many years ago I managed to run a 2 stroke moped on a lot of different solvents. Most notably leather polish mixed with vegetable oil and CRC 5-56. My guess is that if the motor is not to complicated ut will run on anything close to it's intended fuel. It might hurt it in the long run though.
This experiment is useless in a way, unless you ran it for around 100-200+ hours on each fuel. Diesels run on any oil, by their initial and basic design (mercedes calls their diesel engine by OM code, as in oilmotor for a reason), that's nothing wow about it. The issue is with these random oils, like heating oil, is the additives in them. Or for straight raw vegetable oil, it's viscosity and injector design on modern diesels that don't account for such a high viscosity. Or the way the piston rings are made thinner and thinner to give better mpg, allowing unburned vegetable oil to reach the oil sump, diluting the engine oil.
old deuce military trucks had a manual telling you what fuels it could run on. Diesel of course, kerosene, 2 types of jet fuel, gasoline for emergency, and filtered out motor oil and you could mix it all together if needed
I have run both VAG's IDI and TDI 4, 5 and 6 cylinder (volvo) engines on sunflower oil, corn oil, hydraulic oil, engine oil and generator oil. In warm weather, no problem. In colder temps mixed with diesel if not preheated. Basically all the oils gave more power and lower consumption than pure diesel. 👍
Grape seed oil has a very high ignition point. About 25 years ago in my Country a famous Musician who had retired from touring used to go around to take away food shops that used cooking oil and collected their used oil. he kept it and filtered it and ran it in his diesel 4X4. The oil was free to him.
I make my own Biodiesel and run my 1972 Series 3 Land Rover on it. I also filter waste veg oil, collected from various fast-food outlets. The Land Rover runs just fine on it. I have subscribed to your channel, just to see what else and other videos you come up with.
My father run a Bedford truck for many years, maybe 5 or more on 3 parts crude oil and 2 parts power kerosene. This saved on fuel tax in Australia. Also I met a man running a Toyota Hilux Ute on cooking oil from food shops. He filtered it, to remove food scaps etc.
Very cool video. Thanks for doing it! ON another note though, I hope you didn't ruin your little Diesel Engine doing this... (I know little small diesels cost a lot in the US at least...)
In Germany heating oil is often used for Backup Generators, because you pay less tax on it. In vehicles it's not allowed and it's STEUERHINTERZIEHUNG xD :)
We use to dump a quart of trans fluid in the filter after service she start up perfect. Someone didn't tie off the handle on the oil truck to mark kerosene so we rolled in late filled both trucks up with it and didn't hurt nothing we went to Canada then mass and back to Maine.
my father used to tell me about a tank retriever they had in the korean war that had a fuel selector on the dash that you could select anything combustible, when switched to gasoline it had an oil injector to help with lubrication
you can run a diesel engine on any kind of oil. i ran my ford 7.3 diesel on peppermint oil once and also tried baby oil in it and it ran perfect with both
I tested a Petter single cylinder diesel engine with a variety of fuels and found the same result, except it would not run on petrol/gasoline. . I then took a veterinary syringe with a fine needle and discovered it would run by injecting diesel fuel directly onto the intake while the stopper was pulled out. It did not need any pump or injector at all. You should try it.
That is an universal engine. Now I can carry any random oil so that in case my car runs out of diesel then at least I could reach any nearest diesel pump 👍👍. Great video !!😅😅
