Not really. It was always made to run on mineral oil but was asked by the French if it was possible to run it on vegetable oil and he built an engine for a worldfair running on it.
@@kalijasin in a sense yes but in practice you’ll find many problems with using such fuels for an extended period of time on newer diesels, older diesels running at much lower fuel pressures will be a lot more reliable but definitely don’t try this on anything from the 2000’s on up.
Start on diesel, after warms up, switch tanks to veggie...then 4 miles from home, switch back to diesel. Clean injectors, clean pump, and diesel to start cold or warm.
It's too bad Americans have not been keen on the diesel engine for the everyday car. Although here in Texas bubbas are all about their big diesel trucks even though they rarely use them for what their intent was. That's awesome Gus Fergy that you have a diesel Landcruiser aaaand that you run it on vege oil. And from I can understand the average price for a gallon or equivalent of petro in Europe is a lot...like 5 dollars a gallon? I'm sure the race to take advantage of non petro alternatives is becoming increasingly aggressive across the globe. I just hope, despite what Trump advocates, that we wake up and put more efforts into researching those alternatives before it's too late.
You should try water! The trick is this: Add a cupful of sugar* to your gasoline, and when the tank starts getting empty, refill the tank with water. NOTE! Do NOT turn off your engine when you do this! Keep it running as you add the water. You will hear a slight cough, *but then* it will clear up and will surprise you and all your friends by running clean as a whistle! * *WARNING* USE *ONLY Andy Gravatelli's CORN SYRUP!* not granulated sugar!
*NONSENSE* !! You have to make sure the sugar is in the form of *liquid corn syrup!* It will then make sure that any chlorine or flurides in the water are neutralized! PLEASE! Do *not comment* here unless you have a sound understanding of Chemical Mechanics! Or have been frying chicken for 3 or more years!
Bunny Lebowski You just now edited your first comment before you posted the follow up comment *and* you're thumbing up your own comments. That's pathetic.
It's busted only because replacing all diesel fuel with used vegetable oil wouldn't even cover 5% of all usage and wouldn't be free anymore. Biodiesel isn't make from waste vegetable oil
@@Bubu567 too expensive. No point in doing that. I mix waste oil with 10% in winter and that is enough of a difference to make it a daily on all weather. 100% in warm weather is no problem at all! If you want to be extra sure add just a tiny bit of petrol. (Less than 5%!) Too much petrol evaporates on the injector after stopping the engine and makes it very hard to restart and gets you a lot of air in the system
Anyone wanting to try this experiment long term, would be well advised to run normal, commercially obtainable diesel fuel and french fry cooking oil in a 50/50 mix. The commercial diesel fuel has additives that are designed to keep the engine clean and free from build up etc. Depending on the engine, you can also burn Kerosine successfully in a diesel engine. Happy (diesel) motoring.
The key is just not to run this in the new common rail diesel engines. The old mechanical pump diesels work great for this. Examples: 70s-90s mercedes diesels. Early ALH VW tdi. 12 valve dodge cummins. Etc. Just make sure its filtered good
Hey! We are driving from Alaska to Patagonia in Chile on waste cooking oil... we let you guys know the results once we arrive in Chile. WE already went from Vancouver up to Alaska, and the Yukon and recycled more than 1400 liters of cooking oil... overall is a great experience...
What’s interesting is vegetable oil has 10% less btu’s per gallon and gets 10% less mpg. So the decrease in mpg is a result of the energy in the fuel not the efficiency of the burn. Very cool and good work.
@@alphaomega1351 yea in fact they use human fecies in like Africa process and dry them and they burn good as a charcoal and are way more efficient and cleaner burning
This is a great lie! We don't collect our s*** to burn. Don't say it like it's a normal practice in Africa. It can be done by anyone anywhere who wishes to do so, even the president of America and the queen of England can do it.
+Avaxa Sirvina Turning it into Biodiesel will reduce the usable amount by 30%. You will have glycerin as a waste product of transesterification. The more efficient way of using it is using it as straight oil. Because straight cooking oil has a higher delay in self-ignition after injection, the timing needs to be slightly advanced- to counter the 10% lower efficiency.
you can use it mixed with 25% regular car vehicle diesel , that way you keep the glycerin (which is a fuel also) and have a better fuel that biodiesel and cheaper too.
Diesels also have about a gallon of piping between the gas tank and the engine, so even when they put in the oil, it was still running on the diesel in the pipes. They would've had to run it until the car stopped running to get an accurate measurement
Thats only part of the myth. The whole myth was is there some sort of technology that allows your car to ultra fuel efficient...ie: 100 mpg. THATS what was busted. This part just says veg oil is a viable alt to diesel. But Adam was right, once there is a demand for it, there will be a price to be paid.
Phillip Anderson they were seeing if there was a really efficient fuel for cars, this was the last fuel they tested and it was busted that fuel makers aren't hiding a really efficient fuel
idooops depends on the "efficiency" if this fuel doesn't cost anything then it is more efficient than something that costs cause at the end of the day, fuel efficiency is all about the cost to run a car
@@TheCommanderNZ That's converts to about £1.20 per litre. Most of what we pay is fuel tax and vat. Oil comps only pay £1 a barrel for oil taken out the ground here though. Some other countries charge up to £18 a barrel.
Of you use vegetable oil, it will clog your fuel line components eventually. You have to convert it to biodiesel to avoid that and add some bacreria eliminating additives too.
+Цзин Кэ YES, absolutely. When Rudolph Diesel invented his dieselengine in 1897 there was no diesel to buy, in fact there were no gasolinestations at all, so what did he use? RD used pressed peanutoil and then he started a worldwide industry which has grown in ways we have to sit down and think of.
Actually, the French Government proposed it, then Diesel HIMSELF experimented on the idea and even figured out how to use it as a lubricant for those early engines as well. It was a collection of proponents that eventually included the inventor and the inventor took the idea further.
Not really. He designed the engine to run on coal dust (because at tge yime they thought oil was going to run out in a few years) but failed to make it run good and went to mineral oil and was then asked to make it run on peanut oil. Vegetable oil never took off as fuel because they discovered a ton of oil fields and mineral oil was a lot more cheaper and run better
There are a few things you have to do to either your car, or the oil itself to keep it from gelling in your fuel pump.One involves chemical additives to the oil, the other is a small tank of diesel that you start the car with, switch to oil, then switch back a few minutes before shutting the car down.It's not just dumping it in and go.Also there are concerns that glycerin(or something) in the used oil might eat the seals in the fuel pump.
If you're looking for more info, please check out our current project to convert used cooking oil to run a boat. th-cam.com/video/7PRuVw_IEgg/w-d-xo.html
Move in Philippines, we dont care about used cooking oil. I think if you ask a restaurant in Philippines for used cooking oil they will give to you all and think you are a cooking oil weirdo.
The second people found out that other people can use something that they throw out to get something for free they thought: hmm well myself a struggling restaurant owner can make a buck!
Done it, been there & its not 'busted'! I bought a '96 Ford Escort 1.8 Diesel (UK) & it ran great. Just waiting to find another non turbo diesel car that I can do the same with. It wasn't the engine that failed on the Escort, it was everything else!
There is a reason why they used old Mercedes to this test. Any diesel made after 2004 would break immediately due to poor fuel quality. Old Merc will drink anything though...
Only partly true. You would have to open up the lines since the oil is more viscous, unless hot. But if you add a spoonful of alcohol, it would thin out the oil, making it usable in new diesel motors.
ardvark84 Actually peanut oil was used by hobbyists that were making motors for bicycles and early cars in the late 1800's. The only reason gasoline and diesel was later used was because Rockerfeller through coercion and lobbying sold these waste products of Standard Oil that primarily sold kerosene for lamps. If you want to buy into the marketing of "premium" fuels, be my guest. There were several successful attempts at using used vegetable oil in newer motors, including Humvees, pick up trucks. I do understand your reluctance on experimenting on brand new motors though, don't get me wrong.
I have been doing this for ten years. it is not a time consuming process. I let it sit for 3 weeks - none of my time required except to pour it into the container. Then I gravity feed it through a filter into another container (drum) - time required only to turn on the tap. Then I pour it into my car and drive. Takes me about an hour to pick up and 'process" 100 gallons. I get the same mileage (exactly) and power with both fuels. I heat it before it goes into the engine to make it easier on the pump, but it runs without the heat anyway.
+Jay Silva Hi Folks I have done this on several vehicles.... I make a smaller tank that will fit under the hood, bend some 3/8 copper tubing and put it into the new tank. Then I plumb the coils into the into the engine coolant system (before it gets to the cab heater). Perhaps not necessary, but I also have a separate 'golden rod' (google it) filter wrapped with 3/8 ID between the tank and the injection pump, to provide some secondary heat and then I made another heat exchanger out of a 3/4" copper pipe with hot water running through it and the fuel line goes through that just before it gets to the IP. Remember I live in a cold climate, but this system even worked when it was -40 deg (yes that is a minus!). You'd had better make sure you don't shut it off at that temp with oil anywhere in the system though if you don't have a way of heating it all up before you want to run it again!because at that temperature the oil freezes just like butter would. I of course have a two tank system where I start on diesel using the main tank and when the engine comes up to temperature I switch over to Veg oil. I switch back to diesel about three km from home to ensure that it can start on diesel only. There are ways around this too, but if you live in a hot climate you won't have to worry about these starting issues. Even at 140 deg F diesel sis still a lot more viscous than diesel, so your pump will be happier with you over the long term if you heat the oil before it goes into the engine. You can tell that this system in a cooler climate isn't much good for around town due to the delays in switching. However, if you have a more modern engine (my last one was a TDi 1.9 VW they have a lot of fuel going through the return lines and don't require more than about 30 seconds to clear the oil form the IP. My current vehicle is a nissan pickup with an SD25 and they hardly return anything through the return lines - hence the longer time to purge before shutdown. None of this is complicated and I can send pictures if you provide your email. No idea how to do that on youtube Side thought....I am not a chemical engineer, but I would avoid mixing gasoline with veggie oil thinking that you can make diesel. I don't think they are the same thing. If you must mix, I'd suggest just mixing it with diesel. Mix at bit at different ratios and leave it outside in your area and see how it thickens (or not). Mix it well or it will tend to separate, but when mixed thoroughly it seems to stay mixed for a few weeks at least (I haven't left it more than that). Hope this helps Cheers
+Jay Silva No Problem. This medium only works if people follow up....otherwise it is just an exercise in frustration - and there is a lot of that on here.
this wont clog anything up if you keep the oil warm and filtered properly. Rudolf Diesel made the Diesel engine to run his own car on peanut oil.... they literally run on ANY type of oil aslong as its thin enough (warm) to not clog the injectors. but hey changing the injectors every now and then would still be cheaper than buying fuel here where i am lol. and what are they talking about busted...? it went the same distance as diesel fuel just about and they even left a little in the tank and hose...
Over a long period of time, straight veg oil trashes the fuel system no matter how clean you refinine it. After about 200k miles. You are replacing injectors, fuel lines, and filter systems, A layer of sludge builds up and is a pain to get out. Stick with straight diesel or at least blended biodiesel.
I have a friend who has been running his on used vege oil for a few years with no issues at all. well, it does give off a greasy smell lol! But, he said not every Diesel engine will work. He said older engines work best. He also bought a big old military generator from somewhere and runs it on the same oil. The generator is used to help run his place of business. Saves big time on utility bills.
dean tape Diesel engines can run on any thing including Propane and LNG... The US Army HUMVEE can run both gas and Diesel in the 6.5L Detroit Diesel that was in 1990's Chevy Trucks. The problem with running other fuels in Diesel engines is not what happens in the cylinder, the Engine will always be fine.... It's what the other fuel will do to your fuel system (pump, hoses, ect), and getting the right air fuel mixture... In older Diesels from the 1970's if you put gas in a Diesel it would run like garbage but once you burned the fuel off it was fine agian... If you played around with the Air Fuel mixture you could put gas in a Diesel just fine.
I've been running it for 70k miles. I also have a video posted of my truck pulling on it. Heat is the secret. My engine warms up on diesel fuel, then switches to veg oil at 160 degrees. The veg oil is also preheated.
I wouldn't try that. The magic temperature is 160*f or higher. At that temperature, the viscosity of waste vegetable oil is about the same as that of diesel. This helps it atomize properly and prevent cooking that sticks rings and scores cylinders, basically destroying the engine.
emmmm. busted as the hypothesis was increased efficiency, but not busted as a cheaper fuel. and it burns cleaner, been and got the tshirt on this, done it years ago in a taxi for a year
The whole point of efficiency is to save money. So they're stupid if they think the myth is busted. Diesel is obviously a lot more energy dense than oil, I could've told you that without having to do a test like that.
@@TheSuperBoyProject actually canola and corn give almost identical mpg as diesel, and burns slightly quieter, I've done thousands of miles of driving on it over many years as I ran it in my taxi.
I actually own a 1991 Mercedes W124 Diesel 173,000 miles but still tight as a drum I have been using used cooking oil in it for almost a year and it is great saves a lot of money on fuel
This is how I do it: All of the used oils and hydraulic fluids I collect at home I catch as clean as possible in a catch can I keep sealed in double trash bags. When full, I pour the 15 qts into 5-qt oil jugs I save from new oil/fluid changes. I let the jugs sit for at least 90 days and then slowly pour off the top 4 quarts. The last quart has the settled solids or contamination in it. I mix 3 gal of the clean used oil with gasoline nearly 1:1 in 5 gallon fuel cans and shake for 1 minute, and put two 5-gallons cans into a 3/4 full tank of diesel. My 2005 Ram diesel has a 40 gallon tank. This makes a mix of about 15% used oils. It seems to run fine Winter and Summer. I do change my fuel filter a little sooner than typical, about every 10,000 miles, rather than 15,000. The dirty oil left in each jug i combine again and let settle another 90 days and repeat. The 2nd time I pour off the top and use the remainder as chain-lube and make two-cycle fuel for my chainsaw, and some start my wood boiler at night. It's a cheap and easy way to get rid of collected fluids, have a little free fuel, and not waste anything either. Peace and free fuel!
part 2 Another way to use WVO in your diesel car is to convert it to biodiesel. There are many resources online explaining how to do this. With any of these 3 types of alternate fuel for your diesel engine, they cannot be used when cold, not as much of a problem as with biodiesel vs WVO and SVO but biodiesel gels at a higher temp than regular diesel
@shpensive Great! Thank you very much, I think I might start doing this in my diesel, seems like a good idea. Thanks again for the reply, it's much appreciated.
@mrjdl1971 Biodiesel can be used in all engines designed for diesel, including turbo-diesels like the VW TDI engines. Other than being a bit more solvent, it performs much like diesel, though it gels at a higher temp (needs a tank heater in frigid weather). WVO can leave residues that can clog or damage fuel injectors at the higher pressures and temps in turbo-diesels. The car they used was an old Mercedes that does not have turbo boost, and thus avoids those issues.
Thanks, skwurlking82. So first your filter the oil like they did in the video and then how do these filters work under the hood? It does sound like something you'll need a bit of engeneering knowledge for, right? And like Bluefoxkung mentioned, does it harm the engine or is it okay when you use a couple of filters?
Conversion in to actual biofuel requires you to react vegetable oil with methanol, using sodium or potassium hydroxide as the catalyst. You would then filter out the glycerol and you would be left with methyl esters that would serve as a suitable replacement for diesel. It is economical too.
Seems to work out just fine on a friend's 2005-ish Ram 2500 turbodiesel. Drove it a couple thousand miles in a week, burning only a few gallons of diesel (warmup and purge). I think it might have needed a new filter on the trip, but that was a filter he had been running for a while before we even left. Then again, the cummins in his truck might not be considered as "high efficiency" as you are referring to.
Just curious.. would this same idea work. If you were to purchase a large size diesel generator for your home. Could you drive to a McD's pick up some oil and power your home on French fries?
Nik yes it would work in theory. What my dad did back in the 80s was he took an old engine from a tractor and hooked it up to use as a generator for our grain cleaner on our farm. So now i am wondering if i could get a drum of french fry oil and use it to clean our grain? But for the house generator, it should work great, the power required to run our grain cleaner is higher than any power line could ever think about providing, but a house does not require that extreme power so yes it would work.
I have a beetle TDI that has a second tank for waste veg oil, I dont switch tanks till I reach 150 degrees, I also use a diesel additive to keep the IP properly lubricated, the veggie oil also needs to be dewatered for at least a few days up to a week for the best results, the water and other gunk settles to bottom and you filter the rest through a one micron filter before you put it into tank, finally there is a last filter before the injectors grabbing any leftover debris or water.
That was interesting & I realize the point but if you'll notice the Diesel was less thick. Some people add kerosene or gasoline to thin out the veg oil to a consistency more like Diesel fuel. The added octane would increase mileage but there is a bit of science that goes into the making of Diesel fuel & this random mixing or even the use of straight veg oil will damage Diesel engines under a work load. Fine for the cars but not heavy pulling Diesels as a Diesel mechanic explained it to me.
+RogueTalent541 That's the most illogical thing I've ever read. Once you get that thing up to speed, you barely use ANY power to keep it going. A scooter engine could keep that thing going 35MPH with no problems, it's getting it up to speed that needs power and more fuel. The car may be making less power (and it probably is to some unimportant extent), but that wouldn't have an adverse effect on fuel economy. And really, if you are running your car for free, you really don't have a reason to complain about power loss.
Bullshit. Try release the gas pedal and look at the speedometer. It will slow down slowly but steadily due to vehicle air drag and tyres friction and finally you will stop. It will consume less gas though because when your car is up to speed you are fighting against dynamic friction which is weaker than static friction. The MPG is a good comparison between two identical engines running on different fuels.
Wow I'm loving this 8k video quality. I'm really able to see all the finer details on what's going on without having to be right next to my TV with magnifying glasses binocular.
50% cheapest vegetable oil you can find (just filter it) 40% diesel 10% petrol Mix it up in a container (a barrel or whatever), let it sit for a few days and you are ready to go. Will start at low temperatures (wont freeze), will run smooth, wont have any negative side effects of running on pure vegetable oil. Just remmember you cant use it on modern diesel engines but only on older ones. I have done it with Mercedes C250D 1993 model, Mercedes van 207, 2.4l diesel 1985 model, BMW 525 tds 1995 model, Golf 1.9d 1994 model, Golf 1.6d 1988 model, Audi 80 1.6d 1989 model. All of these made about the same fuel usage but at a much lower cost. I have done about 100.000 km in Mercedes c250 on this fuel in one year and i didnt have a single fuel or engine related problem. All the service was done just on regular base like i run it on normal diesel. Mercedes 207 van i still use today and so far I have done about 200.000 km in a period over 7 years without a single fuel or engine related problem. All other cars i just try and didnt do more than 200-300 km in each (some of them where my friends old cars). My neghbour started using this mix on his renault chamade 1991 model 1.9d maybe a month ago, no problems so far. These cars are cheap and when the fuel is only about half price.. well you get the picture.
Would that work on a 2000 TDI Volkswagen? Can I put the old filtered oil directly in the fuel or I'd have to put a second tank? I guess you were also changing the fuel filter more often? Anything else do I need to know?
I didnt use it on turbo charged engines of later production. I have a passat 2002 model 1.9 TDI 130hp and since its euro3 you cant use this mix. Dont get me wrong it would run but after a while you would make the engine hurt. I put the mix directly in the tank, no aditional work needed. Only on the mercedes 250 i had to remove the pre-filter since it got jammed up more often (like every 2 months) and the filter got changed on normal basis (i dont know the km count since i didnt pay much atention to it but i know it was regullar. On all other cars i just put the mix in the tank and run. I didnt do a single thing to any of the other cars (or the van) and they all run perfectly normal. One more thing, the 207 van run better on mix than on regular diesel. I asked my mechanic (he is a school friend also and his shop is like 20 meters from my house) is it possible. He told me since the old diesels (euro 2 or older) use to run on regular diesel fuel the engines where made for that type of fuel. Now you cant buy diesel fuel but only eurodiesel (new type of diesel) and that fuel is made for new engines and that new fuel simply doesnt have enough oil in it for the old engines. Diesel you buy today hurts old diesel engines (euro 2 or older) and this mix is actually better for your engine and the life span of it will be longer and less work and service will be needed. Crazy but true.
+Justin Larrivée One more thing, you dont need to use the 10% petrol during the summer/spring/autumn. It will run good without petrol but remmember that it will freeze during the winter (or in low temperatures) and you wont be able to start. It will just get mushy and you wont be able to start your car. The 10% petrol takes care of that for you and also ads a bit of kick and power to the mix. But 2 much petrol will hurt the engine. I never went above 10% (during winter) and in the summer i use to put like 1 liter of petrol in 40 litre barrel (20 litre vegetable oil, 19 litre eurodiesel) but it does run a bit better with 10% petrol.
I use a 35% SVO/65% diesel mix in my 2001 Passat estate during the summer and achieve 52mpg average including urban driving and two long journeys on the motorway. Have used it in the winter but the engine really did not like it at very cold temps. Opacity test is very low too :D
I have left a comment above about how my 207 van works better on mix than on normal eurodiesel. Thats why.. just turn the story around.. The old diesels (euro 2 or older) use to run on regular diesel fuel and the engines where made for that type of fuel. Now you cant buy diesel fuel but only eurodiesel (new type of diesel) and that fuel is made for new engines and that new fuel simply doesnt have enough oil in it for the old engines. Diesel you buy today hurts old diesel engines (euro 2 or older) and this mix is actually better for your engine and the life span of it will be longer and less work and service will be needed. So this mix has more oil (like grease not oil like fuel) than modern diesel engines (euro 3 and above) would like.. So it greases up the system since the injectors are far more sensitive.. It will run but you will have some problems in the future.. like you would have to change pre-filters and filters more often and injectors will get clogged up (those are expensive to replace or even service). The more electronics the car has and the more modern it is the more damage it will suffer..
You can't just put vegetable oil in the tank and expect it to run. The oil will gel and clog up the lines/pump. You need a separate tank that's heated just for the vegetable oil and then a transfer switch to change between the 2 fuels.
@@seanmckay3392 This only improves the odds, but not by much. By not using the proper setup you risk clogging up your fuel lines. If you intend to use this on your primary vehicle, that's a risk you can't take.
Great little experiment! Thanks for the clip. I guess the big thing is simply to have lower costs. I've always had a problem with diesel because even modern ones are still noisy and don't drive well, petrol cars always feel better. I also have a problem because diesel gives out a lot more pollution on a local level and real nasty stuff too that causes cancer and other disease. I wonder how better the mpg would be with new not used cooking oil + solvent and also if it really would be cleaner?
I wonder how much difference there are in emissions compared to the diesel. The used veg oil cant be poured anywhere you want because it is considerate as a toxic waste and according to law it has to be taken care of and recycled.
Well, the real deal with bio-diesel is that it actually does need to be kept at a certain temperature for it to work properly in the car - that means that the fuel usually needs to be heated a bit before it works. However, I see nothing wrong with mixing it 50/50 with petroleum-based diesel fuel. On Bouginville, the locals have been running their trucks on home-made coconut oil for decades.
it would get disgusting pretty quickly as there are no detergents in cooking oil performance would start to drop after only a few hundred miles i think
@Fertro well kinda. you want the fuel thinned out so its not like syrup. thick cooking oil dosent atomize well, but if you heat it up it gets thinned out and it can atomize into a fine vapor when its injected into the cylinder, which is much more efficent because it burns more completely.
I have a 300TD with the stock om617, replaced the main and secondary fuel filter beforehand, it runs pretty good and you get the bonus of exhaust smelling like French fries
Not true. You dont need to make biodiesel to run a siesel engine. Filtered waste vegitable oil would work fine if its kept warm enough. However I wouldnt put it in an engine for a long period of time without it getting complely filtered.
T Wayland Yep I run pure wvo, filtered down to 1micron in my diesel landcruiser. Only modification is a flat plate heat exchanger prior to the injector pump. Runs beautifully.
@cristoretornebiblia I do filter any used cooking oil,but only thru a towel or some other cloth to remove any large particles.Lately I've been running my car on used engine oil again filtered thru a cloth.My car is a Jeep cherokee with a VM Diesel 2.5 litre engine.
Not busted. Used cooking oil can be used as an economical diesel fuel. I am just wondering about why people often go further in refining the stuff with NaOH and Methanol?
In fact, almost every clean oil works. I drove on 100% veg oil until it was too cold, and I currently drive at 80% wasted motor oil without any problems.
The best way to clean used oil is a centrifgue. Second best and far easier is having a set of 10inch water filters in a row with cheap paper filters, my set up was 5Micron, 1 Micron, 0,5 Micron and 0.2 Micron, a drum, a pump for dispensing oil and a fuel nozzle. Worked great on a common-rail diesel
what about the optical sensor in the pump? ive been told dirty coloured diesel/wmo mixes dont work in the electronic 6.5 motor? I've got one and would be interested in more info....
This its the great way to save money, and to drive almost free. Long time ago i have old Audi C4 2,5 tdi (140hp) 1996 whitch i have drive on WVO. In the wintern when temperatures in Sweden its -15C, -20C i have my mix on 50% diesel, 50% WVO, when temp its above +3C then i drive 20% diesel, 80% WVO, and in the summer i drive 100% WVO whitout any problems.
With the first tank there was a little more smoke, with the next almost nothing. In the first tank there was a lot of oil for the differentials so it probably depends on the type of oil as well. But for now I have no problems and I hope it will stay that way. 😁
@edreactor the question is always input versus output. if the input energy is more than the output, then there is no pt of converting it because energy input is from diesel.
MythBusters wasn't always about busying myths. Sometimes it was about proving them to be true as well. I own a Powerstroke diesel. I've burned everything from new cooking oil (canola, vegetable, peanut, clear frying oil), used (filtered) cooking oil (same), waste motor oil, transmission fluid, kerosene, red fuel, green fuel, biodiesel, thinned hydraulic oil, etc.. literally almost everything I can get my hands on cheaply. It never hiccups. The mileage does vary slightly, but I believe that's due to different viscosities. Diesel engines are the past AND future. Diesel fuel is nothing more than a byproduct of the refining process. Us dieselers and truckers are paying more at the pump for WASTE FUEL. It makes no sense, but it is what it is. There's a reason diesel fuel owns the commercial transportation industry. Cleaner burning, longer life, and better fuel economy when properly tuned. Get used to it :)
Bout time someone said it! Better fuel economy....No one believe me when I tell them that they should buy a diesel truck cause i get roughly 420 miles on a tank of fuel in my 99 F-350 with the 7.3 and when you start hauling it doesnt bother it much at all. People wanna play around with these "lifted economy cars" (dodge rams with the sissy engine in it and eco boost n whatever sissy truck you can think of) because they get good fuel mileage n I will say, yes they do, but as soon as you wanna haul or tow anything with them you slump from 20-30 mpg to 8 or 10, instead id rather have my 7.3 that burns at a steady 13.5-14.5 all the time and hauls 5 ton like its nothing
+Eazydogg I've opened engines that ran on diesel and those that ran on cooking oil. The cooking oil engines had actually less carbon around the valves and looked cleaner on the piston.
i filter my cooking oil down to 1 micron. the fuel filter in my truck only filters down to 5 microns. thus my fuel is more pure and burns cleaner than the diesel while also lubricating the engine better. (diesel tends to burn very dry)
I live in Barnsley, Sth Yorks mate, and i use no mods straight from the shelf to the tank, i go to catering supply warehouses and get it in 20L drums it works out at 89p a litre ;) I must admit i do mix a bit more diesel in the cold months just to be sure, I am thinking of putting a 12v heater blanket around the fuel filter just for the bad winter days. I have mates who also put a little bit of petrol in the mix too.
the first diesel engine was designed to run on vegetable oil. and you need to PROCESS THE OIL BY ADDING METHANOL, AND REMOVING THE GLYCERIN. before you use it. in 50 years oil will be gone and well be back to fueling engines with vegetable oil
Ummm... wait a minute, is this video about the coolness of running a car on cooking oil, or is it about the fuel efficiency of difference between diesel oil ? I've never heard anyone claim that cooking oil had more energy in it than diesel oil. That said, the fuel companies have already been co-opted by the green freaks into burning alcohol in cars (e10, e20, e50 and e82) in the mix of gasoline with alcohol, which reduces the fuel economy of the car because alcohol has about 50% of the caloric value of pure gasoline. Which means you're paying more at the pump while getting less fuel mileage. Which also means that all that alcohol we are using has to be grown (using land space and water.), harvested (most tractors run on diesel) processed (you know using fuel to cook an organic product and turn it into alcohol), and then shipped in trucks limited to hauling 60,000lbs over the road (because alcohol is caustic and can't be run through pipe lines) in diesel truck tankers to a processing plant to be mixed. Doink.
Not quite.. ethanol has 1/2 the caloric energy as the same volume of gasoline, and diesel has more caloric energy than gasoline. The maximum compression ratio for an alky engine is right at 14:1, maximum compression ratio for a gasoline engine is about 16:1, and diesel engines are at about 23:1. IF... you were to run run a carbureted engine on pure gasoline and then switch to alcohol without making any other changes the engine would run to lean and you would end up burning valves and doing other damage to the engine. IF.. you have a modern engine with electronic fuel injection calibrated for pure gasoline and you try to run alcohol in the same engine you will get the same effect as with the carbureter for the same reasons, because the fuel injectors for a pure gasoline engine will not flow enough fuel to achieve the proper fuel / air ratio to operate the engine safeley. That's why you have vehicles identified as "Flex Fuel" or E10, E20, and E85. The more alcohol you run in a mix, the more fuel the injectors have to be able to flow. I suggest as a test, you take two lawn mowers of the same make and horsepower and run them side by side, one using pure gasoline and one using pure alcohol, using identical volumes of the different fuels and see which one runs out of fuel first. Actually hooking up the lawn mower engines to a generator of some type to generate some load on the engine, you won't be able to run the alcohol fueled engine without jetting it up and when you do jet it up and get it running, it will run for almost half as long as the unmodified engine. You'll have to change the ignition timing on the alcohol engine because alcohol burns slower than gasoline or you'll end up burning the valves on the alcohol engine. What I'm stating is not some kind of theory or belief, it's a time honored group of facts well established through over 100 years of practical experience by millions of engineers, mechanics, and hot rodders. Sorry guys ... you just aren't correct on this one. I really really like your show and think it would be really fun to do what you do.
BUT cellulosic alcohol can come from veggie/tree food scraps, animal poop??.After storms loads of branches & trees come down across towns & cities,, all can be made to fuel flex fuel cars
@markus24q This cooking oil fuel is a lot more viscus than normal diesel fuel. Common rail runs on up to 11000 PSI VS 4000PSI for a normal Diesel engine, which will of course lead to serious problems when run on the viscous Bio-diesel
Rubbish. I have been running my Toyota Landcruiser on filtered vege oil for about 6 years now. No difference in power output or efficiency. The only modification to the engine is a FPHE before the IP. Runs perfectly. No need for bio diesel or any other processes.
***** , He might be just misinformed rather than full of shit. I know as FACT that it has not destroyed my engine. Maybe he has had a bad experience or used it in an engine that didn't like it and made his comments as a result without proper knowledge. Who knows. Who cares. Not me. I run my cruiser on vege oil and it goes great, that's all I really care about.
***** Sorry for the late reply. FPHE = Flat Plate Heat Exchanger, IP= Injector Pump. No need to be amazed. Its very old technology that many people still use today.
so no wars were fought for that cooking oil, no harmful pipelines were built and leaked for that oil , no ocean life was ruined due to offshore drilling, no one's health was effected for that vegetable oil , the air is cleaner with that oil due to less green house gases released - this oil can be recycled from our food- hemp can also make oil and the rest of the plant can replace fibers,pulp,plastics and it still make food and grows in under 3 months !! #votegreen and let's get some stuff moving in the right direction !! Hemp does it's part by breathing in 4x the carbon dioxide (CO2) of trees during it's quick 12-14 week growing cycle. Trees take 20 years to mature vs 4 months for Industrial Hemp! Our forests are being cut down 3x faster than they can grow!
Generators will also run on cooking oil, which charge electric motors. So, imagine the miles on electric engines charged with cooking oil. I am thinking hundreds of miles, maybe?
+Xylius Schaaij It would work though, right? If no diesel was available, or you had a stock pile of vegetable oil during a power outage, the oil could power a battery charging station. Im uncertain, but perhaps the least expensive method would be solar, wind, or hydroelectric power in the long run, if there were enough batteries, but then there is the cost to manufacture them. I figure the lifespan of a diesel motor would outlast the life of the batteries needed for an electric motor. Diesel overall sounds like the most efficient fuel source for a motor vehicle.
Yes. Goes of in form of heat, sound and friction. This in the engine that will turn the electric generator, and the generator will have a 90% of efficiency, after that the electric car will lost energy when charging in form of heat, and the electric motor will have a lost to but electric motor can regenerate energy while braking or when they are reducing the speed. By the way... Its how this works. We burn coal, natural gas and diesel to generate electric energy.
I tried the vegetable oil route for a while. It works as advertised. However I have heard of a few folks who wrecked their injection pumps because of the high viscosity - you should heat the oil to 180 degrees. Below 100 degrees the fats started to solidify and plug the filter. I found myself not being able to get the system going in the morning. You need a heater IN or ON the filter. Kudos to those who do this but I ended up deciding $3-4 a gallon at the pump is worth what you pay for it.
How was this "myth" "busted?" You CAN run a car on used cooking oil but it's not as efficient... But it IS free... sort of. We essentially have an endless supply with the right infrastructure in place.
also you have to remember the engine was already nice and hot from the diesel when they tested this. my unmodified golf runs perfect on SVO when hot, its just getting it to start when cold thats the problem.
I stopped watching these guys when they started doing experiments that I've done that works that they said didn't and made it look like it was a scam and it was not a scam.
This test is extremely unscientific: To produce that vegetable oil (I'll assume that it is soy oil, as it is the most common) was used diesel to run the trucks and tractors! To anyone that wanna to study this matter of fuel, energy and efficiency I totally recommend the Patzek and Pimentel's works, go and study them carefully, you won't be disappointed!
The Mythbusters tested if a diesel engine could run on untreated used cooking oil. The test was a success, it did in fact work. The process to create any cooking oil, vegetable or seed, can be inefficient, whether environmentally or economically...but the bigger picture tells a different story. The cooking oil is most probably trucked to restaurants, which in turn can power the trucks, and the farm equipment. There will always be used cooking oil if someone wants fries. Why not recycle it, and use it as fuel? It's economical and efficient since you're using what has already been produced. As far as I know, used cooking oil doesn't damage diesel engines if it is filtered properly.
The point isn't whether it functions or not, of course it functions; (the first diesel motor engineered by the German inventor Rudolf Diesel was devised to function on peanuts oil). There's at least two unfair points, that could fool really a lot of people: * The effects in the long run wasn't tested, as it could damage the engine; * The production of the vegetable oil uses diesel from petroleum, so it isn't a "renewable" source of energy. Of course if the economic conditions permit, one can and must recycle the used cooking oil, but it isn't economic viable all the times and in all situations. Thank you for your time and best regards!
baianoise It's just mythbusters, thjey don't dig very deep. Your right there is problem with cooking oil, it's a lot thicker and a lot of people recommend to heat it up before use. Using dirty cooking oil that is 'filtered' would be something I only would do with a old diesel car. To be honest, nothing is renewable really, when we using machines powered by fossil fuel on one way or another. The thing is using a waste product will use less fossil fuel then just wasting it. Where are not going to stop use fossil fuel until the it is so rare/expensive that it's cheaper to grow different crops to create bio fuel.
baianoise dont see your point since they are just reusing use oil thrown out so your agruement about the stuff use to harvest it is in valid its a stuff that is gonna be thrown out anyway and reusing it as fuel is not such a bad idea though using unuse veg oil which your pointing our is kinda wasteful but using use oil is not wasteful using something that people throw out is not really a bad idea
Felix Jr Lim Well, these question are really trick because they aren't very evident at a first glance; we should ask ourselves: - What is the point in use the waste cooking oil? Answer: we use for the sake of its energy content, not for itself. For a energy source be profitable (in the energy balance sense not only in the economic sense, as the government subsidies sometimes pervert the laws of physics and "magically" turns a non profitable energy source in a profitable one) it must deliver more energy in it's use than the summation of all energy inputs used in its production and/or extraction. In that case of the used cooking oil, its energy inputs was: - all energy used in the sowing and harvesting of the grain, his processing till the extraction of the oil, its filtering degumming, etc - the energy used in the cooking of oil, be it electric or from natural gas, coal, etc. - the energy used in the transportation of oil to the fuel processing facility. Now imagine it in a national scale, millions of cars using that sort of oil? I agree with you that, in the strict economic sense, from the point of view of the people who took the oil from the restaurant (specially if it was at no charge) and burned it in his car, it was indeed very advantageous, but the economy can't change the physical reality: the thermodynamics calculations, as we have spent more energy than has been delivered. Sorry for the long answer, and I hope that I have been clear.
People tend to forget that the engine Rudolph Diesel built was designed to run on vegetable oil.
peanut oil but ya pretty much the same thing
Not really. It was always made to run on mineral oil but was asked by the French if it was possible to run it on vegetable oil and he built an engine for a worldfair running on it.
@@phantomsoldier497 will run on pretty much any oil; vegetable, peanut, mineral, etc.
@@kalijasin in a sense yes but in practice you’ll find many problems with using such fuels for an extended period of time on newer diesels, older diesels running at much lower fuel pressures will be a lot more reliable but definitely don’t try this on anything from the 2000’s on up.
@@emailshe I know several people who run their cars on waste vegetable oil. It does smell kinda like fries lol.
Start on diesel, after warms up, switch tanks to veggie...then 4 miles from home, switch back to diesel. Clean injectors, clean pump, and diesel to start cold or warm.
Agreed. That is exactly what I do with my diesel Landcruiser. I run a diesel tank and a vege tank and a switch between them.
+Sarah Lakenes how do you switch?
+Sarah Lakenes
That's not for those who forget to switch back.
Better make the car run and start on oil straight away.
+Gus Fergy hey can i ask how long youve been running it like that? as far as no long term issues? no carbon? no comp.issues?
It's too bad Americans have not been keen on the diesel engine for the everyday car. Although here in Texas bubbas are all about their big diesel trucks even though they rarely use them for what their intent was. That's awesome Gus Fergy that you have a diesel Landcruiser aaaand that you run it on vege oil. And from I can understand the average price for a gallon or equivalent of petro in Europe is a lot...like 5 dollars a gallon? I'm sure the race to take advantage of non petro alternatives is becoming increasingly aggressive across the globe. I just hope, despite what Trump advocates, that we wake up and put more efforts into researching those alternatives before it's too late.
I tried this, And as it turns out my car is not a diesel.
hehe
You should try water! The trick is this: Add a cupful of sugar* to your gasoline, and when the tank starts getting empty, refill the tank with water.
NOTE! Do NOT turn off your engine when you do this! Keep it running as you add the water. You will hear a slight cough, *but then* it will clear up and will surprise you and all your friends by running clean as a whistle!
* *WARNING* USE *ONLY Andy Gravatelli's CORN SYRUP!* not granulated sugar!
Do not add water or sugar to your fuel tank. This is malicious advice. Your car will be irreversibly damaged.
*NONSENSE* !!
You have to make sure the sugar is in the form of *liquid corn syrup!*
It will then make sure that any chlorine or flurides in the water are neutralized!

It's busted only because replacing all diesel fuel with used vegetable oil wouldn't even cover 5% of all usage and wouldn't be free anymore.

@@Bubu567 too expensive. No point in doing that. I mix waste oil with 10% in winter and that is enough of a difference to make it a daily on all weather. 100% in warm weather is no problem at all! If you want to be extra sure add just a tiny bit of petrol. (Less than 5%!) Too much petrol evaporates on the injector after stopping the engine and makes it very hard to restart and gets you a lot of air in the system
@@Bubu567 ok that's a completly different story.
@@no-damn-alias what engine?
Anyone wanting to try this experiment long term, would be well advised to run normal, commercially obtainable diesel fuel and french fry cooking oil in a 50/50 mix. The commercial diesel fuel has additives that are designed to keep the engine clean and free from build up etc. Depending on the engine, you can also burn Kerosine successfully in a diesel engine. Happy (diesel) motoring.
Seen someone use straight once engine waar in a 2022 deisel
Not that anyone will ever see this, but you can cut it with 5-10% gasoline...
The key is just not to run this in the new common rail diesel engines. The old mechanical pump diesels work great for this. Examples: 70s-90s mercedes diesels. Early ALH VW tdi. 12 valve dodge cummins. Etc.
Just make sure its filtered good

What’s interesting is vegetable oil has 10% less btu’s per gallon and gets 10% less mpg.
So the decrease in mpg is a result of the energy in the fuel not the efficiency of the burn.

Not busted in my opinion. Refinement into biodiesel would increase the efficiency and not require as many fuel filter replacements
+Avaxa Sirvina Their discussion at the end seemed very lacking...
+Avaxa Sirvina Turning it into Biodiesel will reduce the usable amount by 30%.
You will have glycerin as a waste product of transesterification.
The more efficient way of using it is using it as straight oil.
Because straight cooking oil has a higher delay in self-ignition after injection, the timing needs to be slightly advanced- to counter the 10% lower efficiency.
you can use it mixed with 25% regular car vehicle diesel , that way you keep the glycerin (which is a fuel also) and have a better fuel that biodiesel and cheaper too.
Diesels also have about a gallon of piping between the gas tank and the engine, so even when they put in the oil, it was still running on the diesel in the pipes. They would've had to run it until the car stopped running to get an accurate measurement
Thats only part of the myth. The whole myth was is there some sort of technology that allows your car to ultra fuel efficient...ie: 100 mpg. THATS what was busted. This part just says veg oil is a viable alt to diesel. But Adam was right, once there is a demand for it, there will be a price to be paid.
Wait a minute! At nearly $4.00 per gallon VS free, and it's busted? Then I prefer busted. Sheees!
They are paid and bought to not say these things
Phillip Anderson they were seeing if there was a really efficient fuel for cars, this was the last fuel they tested and it was busted that fuel makers aren't hiding a really efficient fuel
They were testing various products on the market that claim to increase fuel efficiency. None of them worked.
idooops depends on the "efficiency" if this fuel doesn't cost anything then it is more efficient than something that costs
cause at the end of the day, fuel efficiency is all about the cost to run a car
Killah Priest efficiency is miles per gallon. Price doesn't effect mpg. Which is what they're testing. You're thinking of economic/financial impact
I see this being a good alternative to diesel right about now.
In the UK normal diesel is approaching £2 a litre, veg oil can be had for £1.09 a litre. New engines don't like it though

Of you use vegetable oil, it will clog your fuel line components eventually. You have to convert it to biodiesel to avoid that and add some bacreria eliminating additives too.
no if you filter it it wont like they did if you actually watched the video
OMG! THE ENGINE THAT WAS CREATED TO USE VEGETABLE OIL AS A FUEL, ACTUALLY USE IT! THAT'S WONDERFUL!
Are you serious?
+Цзин Кэ YES, absolutely. When Rudolph Diesel invented his dieselengine in 1897 there was no diesel to buy,
in fact there were no gasolinestations at all, so what did he use? RD used pressed peanutoil and then he started
a worldwide industry which has grown in ways we have to sit down and think of.
Actually, the French Government proposed it, then Diesel HIMSELF experimented on the idea and even figured out how to use it as a lubricant for those early engines as well.
It was a collection of proponents that eventually included the inventor and the inventor took the idea further.
@@Interdiction He suicided or some country's government hated him.
Not really. He designed the engine to run on coal dust (because at tge yime they thought oil was going to run out in a few years) but failed to make it run good and went to mineral oil and was then asked to make it run on peanut oil. Vegetable oil never took off as fuel because they discovered a ton of oil fields and mineral oil was a lot more cheaper and run better
They were designed to run on it over 100 years ago, no modern diesel is made with this in mind
There are a few things you have to do to either your car, or the oil itself to keep it from gelling in your fuel pump.One involves chemical additives to the oil, the other is a small tank of diesel that you start the car with, switch to oil, then switch back a few minutes before shutting the car down.It's not just dumping it in and go.Also there are concerns that glycerin(or something) in the used oil might eat the seals in the fuel pump.

Explain
Only partly true. You would have to open up the lines since the oil is more viscous, unless hot. But if you add a spoonful of alcohol, it would thin out the oil, making it usable in new diesel motors.
Alen Combs
Maybe so but this can be a very expensive experiment...
ardvark84 Actually peanut oil was used by hobbyists that were making motors for bicycles and early cars in the late 1800's. The only reason gasoline and diesel was later used was because Rockerfeller through coercion and lobbying sold these waste products of Standard Oil that primarily sold kerosene for lamps. If you want to buy into the marketing of "premium" fuels, be my guest. There were several successful attempts at using used vegetable oil in newer motors, including Humvees, pick up trucks. I do understand your reluctance on experimenting on brand new motors though, don't get me wrong.
I have been doing this for ten years.
it is not a time consuming process. I let it sit for 3 weeks - none of my time required except to pour it into the container. Then I gravity feed it through a filter into another container (drum) - time required only to turn on the tap. Then I pour it into my car and drive. Takes me about an hour to pick up and 'process" 100 gallons.
I get the same mileage (exactly) and power with both fuels. I heat it before it goes into the engine to make it easier on the pump, but it runs without the heat anyway.
+Gerry S "I heat it before it goes into the engine" you said.. How do you do that(let say, in the morning for exemple)?..
+Jay Silva
Hi Folks
I have done this on several vehicles....
I make a smaller tank that will fit under the hood, bend some 3/8 copper tubing and put it into the new tank. Then I plumb the coils into the into the engine coolant system (before it gets to the cab heater). Perhaps not necessary, but I also have a separate 'golden rod' (google it) filter wrapped with 3/8 ID between the tank and the injection pump, to provide some secondary heat and then I made another heat exchanger out of a 3/4" copper pipe with hot water running through it and the fuel line goes through that just before it gets to the IP. Remember I live in a cold climate, but this system even worked when it was -40 deg (yes that is a minus!). You'd had better make sure you don't shut it off at that temp with oil anywhere in the system though if you don't have a way of heating it all up before you want to run it again!because at that temperature the oil freezes just like butter would.
I of course have a two tank system where I start on diesel using the main tank and when the engine comes up to temperature I switch over to Veg oil. I switch back to diesel about three km from home to ensure that it can start on diesel only. There are ways around this too, but if you live in a hot climate you won't have to worry about these starting issues.
Even at 140 deg F diesel sis still a lot more viscous than diesel, so your pump will be happier with you over the long term if you heat the oil before it goes into the engine.
You can tell that this system in a cooler climate isn't much good for around town due to the delays in switching. However, if you have a more modern engine (my last one was a TDi 1.9 VW they have a lot of fuel going through the return lines and don't require more than about 30 seconds to clear the oil form the IP. My current vehicle is a nissan pickup with an SD25 and they hardly return anything through the return lines - hence the longer time to purge before shutdown.
None of this is complicated and I can send pictures if you provide your email. No idea how to do that on youtube
Side thought....I am not a chemical engineer, but I would avoid mixing gasoline with veggie oil thinking that you can make diesel. I don't think they are the same thing. If you must mix, I'd suggest just mixing it with diesel. Mix at bit at different ratios and leave it outside in your area and see how it thickens (or not). Mix it well or it will tend to separate, but when mixed thoroughly it seems to stay mixed for a few weeks at least (I haven't left it more than that).
Hope this helps
Cheers

@@tylerdurden8524 Thanks Tyler!
i enjoyed the few pixels i could see
this wont clog anything up if you keep the oil warm and filtered properly.
Rudolf Diesel made the Diesel engine to run his own car on peanut oil....
they literally run on ANY type of oil aslong as its thin enough (warm) to not clog the injectors.
but hey changing the injectors every now and then would still be cheaper than buying fuel here where i am lol.
and what are they talking about busted...? it went the same distance as diesel fuel just about and they even left a little in the tank and hose...
when top gear did it they added a very small abut of turps / paint thinners to keep it thin and also help it combust when cold
could be a very good idea
Over a long period of time, straight veg oil trashes the fuel system no matter how clean you refinine it. After about 200k miles. You are replacing injectors, fuel lines, and filter systems, A layer of sludge builds up and is a pain to get out. Stick with straight diesel or at least blended biodiesel.
I have a friend who has been running his on used vege oil for a few years with no issues at all. well, it does give off a greasy smell lol! But, he said not every Diesel engine will work. He said older engines work best. He also bought a big old military generator from somewhere and runs it on the same oil. The generator is used to help run his place of business. Saves big time on utility bills.
dean tape Diesel engines can run on any thing including Propane and LNG...
The US Army HUMVEE can run both gas and Diesel in the 6.5L Detroit Diesel that was in 1990's Chevy Trucks.
The problem with running other fuels in Diesel engines is not what happens in the cylinder, the Engine will always be fine.... It's what the other fuel will do to your fuel system (pump, hoses, ect), and getting the right air fuel mixture... In older Diesels from the 1970's if you put gas in a Diesel it would run like garbage but once you burned the fuel off it was fine agian... If you played around with the Air Fuel mixture you could put gas in a Diesel just fine.
33 mpg at 35 mph is pretty goddamn great for a big boat like that..

I've been running it for 70k miles. I also have a video posted of my truck pulling on it. Heat is the secret. My engine warms up on diesel fuel, then switches to veg oil at 160 degrees. The veg oil is also preheated.
I heard some people use a smaller tank and a light bulb placed inside of it to heat the veg oil.
I wouldn't try that. The magic temperature is 160*f or higher. At that temperature, the viscosity of waste vegetable oil is about the same as that of diesel. This helps it atomize properly and prevent cooking that sticks rings and scores cylinders, basically destroying the engine.
emmmm. busted as the hypothesis was increased efficiency, but not busted as a cheaper fuel. and it burns cleaner, been and got the tshirt on this, done it years ago in a taxi for a year
The whole point of efficiency is to save money. So they're stupid if they think the myth is busted. Diesel is obviously a lot more energy dense than oil, I could've told you that without having to do a test like that.
@@TheSuperBoyProject actually canola and corn give almost identical mpg as diesel, and burns slightly quieter, I've done thousands of miles of driving on it over many years as I ran it in my taxi.
I actually own a 1991 Mercedes W124 Diesel
173,000 miles but still tight as a drum
I have been using used cooking oil in it for almost a year and it is great
saves a lot of money on fuel
This is how I do it:
All of the used oils and hydraulic fluids I collect at home I catch as clean as possible in a catch can I keep sealed in double trash bags. When full, I pour the 15 qts into 5-qt oil jugs I save from new oil/fluid changes. I let the jugs sit for at least 90 days and then slowly pour off the top 4 quarts. The last quart has the settled solids or contamination in it.
I mix 3 gal of the clean used oil with gasoline nearly 1:1 in 5 gallon fuel cans and shake for 1 minute, and put two 5-gallons cans into a 3/4 full tank of diesel. My 2005 Ram diesel has a 40 gallon tank. This makes a mix of about 15% used oils. It seems to run fine Winter and Summer. I do change my fuel filter a little sooner than typical, about every 10,000 miles, rather than 15,000.
The dirty oil left in each jug i combine again and let settle another 90 days and repeat. The 2nd time I pour off the top and use the remainder as chain-lube and make two-cycle fuel for my chainsaw, and some start my wood boiler at night.
It's a cheap and easy way to get rid of collected fluids, have a little free fuel, and not waste anything either.
Peace and free fuel!
There should be enough oil in a medium city to fill about two gas tanks a day ,, very much worth the effort
I think these guys are sponsored by big oil.
Used cooking oil literally works, and works well! Just gotta add a small solvent to the oil.
part 2
Another way to use WVO in your diesel car is to convert it to biodiesel. There are many resources online explaining how to do this. With any of these 3 types of alternate fuel for your diesel engine, they cannot be used when cold, not as much of a problem as with biodiesel vs WVO and SVO but biodiesel gels at a higher temp than regular diesel
@shpensive Great! Thank you very much, I think I might start doing this in my diesel, seems like a good idea. Thanks again for the reply, it's much appreciated.
THE BEST PART IS YOUR EXHAUST SMELLS LIKE FRENCH FRIES!! :DD
Here, class, is a textbook example of missing the point.
Also vegetable oil is renewable, sustainable , lower emissions and smells better.
@mrjdl1971 Biodiesel can be used in all engines designed for diesel, including turbo-diesels like the VW TDI engines. Other than being a bit more solvent, it performs much like diesel, though it gels at a higher temp (needs a tank heater in frigid weather). WVO can leave residues that can clog or damage fuel injectors at the higher pressures and temps in turbo-diesels. The car they used was an old Mercedes that does not have turbo boost, and thus avoids those issues.
Thanks, skwurlking82. So first your filter the oil like they did in the video and then how do these filters work under the hood? It does sound like something you'll need a bit of engeneering knowledge for, right?
And like Bluefoxkung mentioned, does it harm the engine or is it okay when you use a couple of filters?
144p we meet again :)
LMAO
We drove like this for 2 - 3 years. We always bought 10 liters of regular Diesel and filled the rest of the tank with the filtered oil :)
While the temperature is around 10C or higher, I drove at 100% veg oil without any problems.
Conversion in to actual biofuel requires you to react vegetable oil with methanol, using sodium or potassium hydroxide as the catalyst. You would then filter out the glycerol and you would be left with methyl esters that would serve as a suitable replacement for diesel. It is economical too.
Seems to work out just fine on a friend's 2005-ish Ram 2500 turbodiesel. Drove it a couple thousand miles in a week, burning only a few gallons of diesel (warmup and purge). I think it might have needed a new filter on the trip, but that was a filter he had been running for a while before we even left.
Then again, the cummins in his truck might not be considered as "high efficiency" as you are referring to.
In case of Zombie Apocalypse, I won't care about a less efficient fuel.
ok, you wait for that...LOL

@@V8AmericanMuscleCar ***** ???
Just curious.. would this same idea work. If you were to purchase a large size diesel generator for your home. Could you drive to a McD's pick up some oil and power your home on French fries?
Nik yes it would work in theory. What my dad did back in the 80s was he took an old engine from a tractor and hooked it up to use as a generator for our grain cleaner on our farm. So now i am wondering if i could get a drum of french fry oil and use it to clean our grain? But for the house generator, it should work great, the power required to run our grain cleaner is higher than any power line could ever think about providing, but a house does not require that extreme power so yes it would work.
Don't try it because there is more to it then just filtering the oil not to harm the engine
YES!! I use coolant to supply heat!!
I have a beetle TDI that has a second tank for waste veg oil, I dont switch tanks till I reach 150 degrees, I also use a diesel additive to keep the IP properly lubricated, the veggie oil also needs to be dewatered for at least a few days up to a week for the best results, the water and other gunk settles to bottom and you filter the rest through a one micron filter before you put it into tank, finally there is a last filter before the injectors grabbing any leftover debris or water.
That was interesting & I realize the point but if you'll notice the Diesel was less thick. Some people add kerosene or gasoline to thin out the veg oil to a consistency more like Diesel fuel. The added octane would increase mileage but there is a bit of science that goes into the making of Diesel fuel & this random mixing or even the use of straight veg oil will damage Diesel engines under a work load. Fine for the cars but not heavy pulling Diesels as a Diesel mechanic explained it to me.
The one important thing they failed to test.
Power output. Put the car on a dyno, see if it makes more or less power with veg oil.
+Mohamed ThePedophile It makes less. Hence the less mpg.
interesting profile name,
+RogueTalent541 That's the most illogical thing I've ever read. Once you get that thing up to speed, you barely use ANY power to keep it going. A scooter engine could keep that thing going 35MPH with no problems, it's getting it up to speed that needs power and more fuel.
The car may be making less power (and it probably is to some unimportant extent), but that wouldn't have an adverse effect on fuel economy. And really, if you are running your car for free, you really don't have a reason to complain about power loss.
Well yes, but as the cooking oil is a bit less powerful the car needs a bit more to keep it at 35mph
Bullshit. Try release the gas pedal and look at the speedometer. It will slow down slowly but steadily due to vehicle air drag and tyres friction and finally you will stop. It will consume less gas though because when your car is up to speed you are fighting against dynamic friction which is weaker than static friction. The MPG is a good comparison between two identical engines running on different fuels.
won't work anymore on newer diesel cars this only works on older ones.
Wow I'm loving this 8k video quality. I'm really able to see all the finer details on what's going on without having to be right next to my TV with magnifying glasses binocular.
If only there was 8k 15 years ago, when the video was uploaded.
I have two XJ Jeeps with factory 2.5 turbo diesel engines. When it’s not cold I drive on 100% vegetable oil and works great!!! 😃
50% cheapest vegetable oil you can find (just filter it)
40% diesel
10% petrol
Mix it up in a container (a barrel or whatever), let it sit for a few days and you are ready to go.
Will start at low temperatures (wont freeze), will run smooth, wont have any negative side effects of running on pure vegetable oil. Just remmember you cant use it on modern diesel engines but only on older ones. I have done it with Mercedes C250D 1993 model, Mercedes van 207, 2.4l diesel 1985 model, BMW 525 tds 1995 model, Golf 1.9d 1994 model, Golf 1.6d 1988 model, Audi 80 1.6d 1989 model.
All of these made about the same fuel usage but at a much lower cost.
I have done about 100.000 km in Mercedes c250 on this fuel in one year and i didnt have a single fuel or engine related problem. All the service was done just on regular base like i run it on normal diesel.
Mercedes 207 van i still use today and so far I have done about 200.000 km in a period over 7 years without a single fuel or engine related problem.
All other cars i just try and didnt do more than 200-300 km in each (some of them where my friends old cars). My neghbour started using this mix on his renault chamade 1991 model 1.9d maybe a month ago, no problems so far.
These cars are cheap and when the fuel is only about half price.. well you get the picture.
Would that work on a 2000 TDI Volkswagen? Can I put the old filtered oil directly in the fuel or I'd have to put a second tank? I guess you were also changing the fuel filter more often? Anything else do I need to know?
I didnt use it on turbo charged engines of later production. I have a passat 2002 model 1.9 TDI 130hp and since its euro3 you cant use this mix. Dont get me wrong it would run but after a while you would make the engine hurt.
I put the mix directly in the tank, no aditional work needed. Only on the mercedes 250 i had to remove the pre-filter since it got jammed up more often (like every 2 months) and the filter got changed on normal basis (i dont know the km count since i didnt pay much atention to it but i know it was regullar.
On all other cars i just put the mix in the tank and run. I didnt do a single thing to any of the other cars (or the van) and they all run perfectly normal.
One more thing, the 207 van run better on mix than on regular diesel. I asked my mechanic (he is a school friend also and his shop is like 20 meters from my house) is it possible. He told me since the old diesels (euro 2 or older) use to run on regular diesel fuel the engines where made for that type of fuel. Now you cant buy diesel fuel but only eurodiesel (new type of diesel) and that fuel is made for new engines and that new fuel simply doesnt have enough oil in it for the old engines.
Diesel you buy today hurts old diesel engines (euro 2 or older) and this mix is actually better for your engine and the life span of it will be longer and less work and service will be needed.
Crazy but true.
+Justin Larrivée
One more thing, you dont need to use the 10% petrol during the summer/spring/autumn. It will run good without petrol but remmember that it will freeze during the winter (or in low temperatures) and you wont be able to start. It will just get mushy and you wont be able to start your car. The 10% petrol takes care of that for you and also ads a bit of kick and power to the mix. But 2 much petrol will hurt the engine. I never went above 10% (during winter) and in the summer i use to put like 1 liter of petrol in 40 litre barrel (20 litre vegetable oil, 19 litre eurodiesel) but it does run a bit better with 10% petrol.
I use a 35% SVO/65% diesel mix in my 2001 Passat estate during the summer and achieve 52mpg average including urban driving and two long journeys on the motorway. Have used it in the winter but the engine really did not like it at very cold temps. Opacity test is very low too :D
I have left a comment above about how my 207 van works better on mix than on normal eurodiesel. Thats why.. just turn the story around..
The old diesels (euro 2 or older) use to run on regular diesel fuel and the engines where made for that type of fuel. Now you cant buy diesel fuel but only eurodiesel (new type of diesel) and that fuel is made for new engines and that new fuel simply doesnt have enough oil in it for the old engines.
Diesel you buy today hurts old diesel engines (euro 2 or older) and this mix is actually better for your engine and the life span of it will be longer and less work and service will be needed.
So this mix has more oil (like grease not oil like fuel) than modern diesel engines (euro 3 and above) would like.. So it greases up the system since the injectors are far more sensitive.. It will run but you will have some problems in the future.. like you would have to change pre-filters and filters more often and injectors will get clogged up (those are expensive to replace or even service). The more electronics the car has and the more modern it is the more damage it will suffer..
You can't just put vegetable oil in the tank and expect it to run. The oil will gel and clog up the lines/pump. You need a separate tank that's heated just for the vegetable oil and then a transfer switch to change between the 2 fuels.
no definitely not true you can just put it in the tank after you filter it just put 20% diesel in with it to give it some sulfur etc
@@seanmckay3392 This only improves the odds, but not by much. By not using the proper setup you risk clogging up your fuel lines. If you intend to use this on your primary vehicle, that's a risk you can't take.
Great little experiment! Thanks for the clip. I guess the big thing is simply to have lower costs. I've always had a problem with diesel because even modern ones are still noisy and don't drive well, petrol cars always feel better. I also have a problem because diesel gives out a lot more pollution on a local level and real nasty stuff too that causes cancer and other disease. I wonder how better the mpg would be with new not used cooking oil + solvent and also if it really would be cleaner?
@MrLabrant What kind of car are you driving? I have a Renault Kangoo 1.5 DCI do you think it would work in its tank?
Would you be able to pass smog just by doing this???
You got any more of them pixels?
The smell of hamburgers coming from your exhaust will raise some eyebrows.
I wonder how much difference there are in emissions compared to the diesel. The used veg oil cant be poured anywhere you want because it is considerate as a toxic waste and according to law it has to be taken care of and recycled.
Well, the real deal with bio-diesel is that it actually does need to be kept at a certain temperature for it to work properly in the car - that means that the fuel usually needs to be heated a bit before it works. However, I see nothing wrong with mixing it 50/50 with petroleum-based diesel fuel. On Bouginville, the locals have been running their trucks on home-made coconut oil for decades.
The big question though is if there are any long term effects on the car from using raw, filtered fry grease
it would get disgusting pretty quickly as there are no detergents in cooking oil performance would start to drop after only a few hundred miles i think
Not really only have change oil more frequent
It gets thick quick in the winter.
Biggest one, engine oil dilution from fuel being used not proper to the injectors
@Fertro well kinda. you want the fuel thinned out so its not like syrup. thick cooking oil dosent atomize well, but if you heat it up it gets thinned out and it can atomize into a fine vapor when its injected into the cylinder, which is much more efficent because it burns more completely.
that is so cool!
LIES! My old 1984 Mercedes 300D can run on straight used veggie oil. I have driven thousands of miles on free grease.
+Dorian Demeturlias my too !!!! :D
Is your benz turbocharged?
BorisGrayman 300d is a turbo model. 240d is not
So your car works exactly like the car they showed and they are lieing????
I have a 300TD with the stock om617, replaced the main and secondary fuel filter beforehand, it runs pretty good and you get the bonus of exhaust smelling like French fries
You need to take out the glycerol out of the oil or it will block up the injectors or anything else it comes in contact with.
Not true. You dont need to make biodiesel to run a siesel engine. Filtered waste vegitable oil would work fine if its kept warm enough. However I wouldnt put it in an engine for a long period of time without it getting complely filtered.
T Wayland Yep I run pure wvo, filtered down to 1micron in my diesel landcruiser. Only modification is a flat plate heat exchanger prior to the injector pump. Runs beautifully.
Gus Fergy , how looks heater link please, thanks
@cristoretornebiblia I do filter any used cooking oil,but only thru a towel or some other cloth to remove any large particles.Lately I've been running my car on used engine oil again filtered thru a cloth.My car is a Jeep cherokee with a VM Diesel 2.5 litre engine.
Not busted.
Used cooking oil can be used as an economical diesel fuel.
I am just wondering about why people often go further in refining the stuff with NaOH and Methanol?
Just use clean cooking oil and you will be fine (sunflower oil) that's the one
Pure Matrix , The cost of fresh Virgin cooking oil would be very costly.
Old Griz still cheaper than using the petrol at the pumps
Depend on the taxes. In some places Diesel is heavy taxed.
In fact, almost every clean oil works. I drove on 100% veg oil until it was too cold, and I currently drive at 80% wasted motor oil without any problems.
Wow, it's quite amazing that this works! With fuel prices the way they are, I bet people would be willing to use this for their diesel vehicles.

The best way to clean used oil is a centrifgue.
Second best and far easier is having a set of 10inch water filters in a row with cheap paper filters, my set up was 5Micron, 1 Micron, 0,5 Micron and 0.2 Micron, a drum, a pump for dispensing oil and a fuel nozzle.
Worked great on a common-rail diesel
what about the optical sensor in the pump? ive been told dirty coloured diesel/wmo mixes dont work in the electronic 6.5 motor? I've got one and would be interested in more info....
This its the great way to save money, and to drive almost free. Long time ago i have old Audi C4 2,5 tdi (140hp) 1996 whitch i have drive on WVO. In the wintern when temperatures in Sweden its -15C, -20C i have my mix on 50% diesel, 50% WVO, when temp its above +3C then i drive 20% diesel, 80% WVO, and in the summer i drive 100% WVO whitout any problems.
I do the same with my old turbo diesel Jeep. Few months ago I tried with wasted motor oil and works great too!
@@V8AmericanMuscleCar
I have tried also WMO but its comes a lot of smoke. Carbon deposits in ERG valve after only 1000km was terrible.
With the first tank there was a little more smoke, with the next almost nothing. In the first tank there was a lot of oil for the differentials so it probably depends on the type of oil as well. But for now I have no problems and I hope it will stay that way. 😁

@@alexa795 thanks! 🙋🏻♂️
in Europa we have BIODIESEL and its made from cooking oil and some aditivs.......
Yes, and it's SHIT !
@edreactor the question is always input versus output. if the input energy is more than the output, then there is no pt of converting it because energy input is from diesel.
I know of a guy who ran his five ton truck on cooking oil and it ran perfectly. He just used a bit of diesel for cold starting!
MythBusters wasn't always about busying myths. Sometimes it was about proving them to be true as well.
I own a Powerstroke diesel. I've burned everything from new cooking oil (canola, vegetable, peanut, clear frying oil), used (filtered) cooking oil (same), waste motor oil, transmission fluid, kerosene, red fuel, green fuel, biodiesel, thinned hydraulic oil, etc.. literally almost everything I can get my hands on cheaply. It never hiccups. The mileage does vary slightly, but I believe that's due to different viscosities.
Diesel engines are the past AND future. Diesel fuel is nothing more than a byproduct of the refining process. Us dieselers and truckers are paying more at the pump for WASTE FUEL. It makes no sense, but it is what it is.
There's a reason diesel fuel owns the commercial transportation industry. Cleaner burning, longer life, and better fuel economy when properly tuned. Get used to it :)
So do you just put all that stuff into the gas tank? I have a 2017 duramax
"Cleaner burning" - Just no.
Hey I also own a 7.3L powerstroke. Do you live in a colder climate?
Bout time someone said it! Better fuel economy....No one believe me when I tell them that they should buy a diesel truck cause i get roughly 420 miles on a tank of fuel in my 99 F-350 with the 7.3 and when you start hauling it doesnt bother it much at all. People wanna play around with these "lifted economy cars" (dodge rams with the sissy engine in it and eco boost n whatever sissy truck you can think of) because they get good fuel mileage n I will say, yes they do, but as soon as you wanna haul or tow anything with them you slump from 20-30 mpg to 8 or 10, instead id rather have my 7.3 that burns at a steady 13.5-14.5 all the time and hauls 5 ton like its nothing
Diesel is not WASTE FUEL even when you capitalize it. It costs more because of supply and demand.
The only downside i think is that it will muck up your engine after prolonged usage
Eazydogg there is a way to deal with that, its called pepsi...
+Eazydogg
I've opened engines that ran on diesel and those that ran on cooking oil.
The cooking oil engines had actually less carbon around the valves and looked cleaner on the piston.
i filter my cooking oil down to 1 micron. the fuel filter in my truck only filters down to 5 microns. thus my fuel is more pure and burns cleaner than the diesel while also lubricating the engine better. (diesel tends to burn very dry)
I live in Barnsley, Sth Yorks mate, and i use no mods straight from the shelf to the tank, i go to catering supply warehouses and get it in 20L drums it works out at 89p a litre ;) I must admit i do mix a bit more diesel in the cold months just to be sure, I am thinking of putting a 12v heater blanket around the fuel filter just for the bad winter days. I have mates who also put a little bit of petrol in the mix too.
the first diesel engine was designed to run on vegetable oil. and you need to PROCESS THE OIL BY ADDING METHANOL, AND REMOVING THE GLYCERIN. before you use it. in 50 years oil will be gone and well be back to fueling engines with vegetable oil
How do ya go along doing this I would love to learn
Ummm... wait a minute, is this video about the coolness of running a car on cooking oil, or is it about the fuel efficiency of difference between diesel oil ? I've never heard anyone claim that cooking oil had more energy in it than diesel oil. That said, the fuel companies have already been co-opted by the green freaks into burning alcohol in cars (e10, e20, e50 and e82) in the mix of gasoline with alcohol, which reduces the fuel economy of the car because alcohol has about 50% of the caloric value of pure gasoline. Which means you're paying more at the pump while getting less fuel mileage. Which also means that all that alcohol we are using has to be grown (using land space and water.), harvested (most tractors run on diesel) processed (you know using fuel to cook an organic product and turn it into alcohol), and then shipped in trucks limited to hauling 60,000lbs over the road (because alcohol is caustic and can't be run through pipe lines) in diesel truck tankers to a processing plant to be mixed. Doink.
Not quite.. ethanol has 1/2 the caloric energy as the same volume of gasoline, and diesel has more caloric energy than gasoline. The maximum compression ratio for an alky engine is right at 14:1, maximum compression ratio for a gasoline engine is about 16:1, and diesel engines are at about 23:1.
IF... you were to run run a carbureted engine on pure gasoline and then switch to alcohol without making any other changes the engine would run to lean and you would end up burning valves and doing other damage to the engine. IF.. you have a modern engine with electronic fuel injection calibrated for pure gasoline and you try to run alcohol in the same engine you will get the same effect as with the carbureter for the same reasons, because the fuel injectors for a pure gasoline engine will not flow enough fuel to achieve the proper fuel / air ratio to operate the engine safeley. That's why you have vehicles identified as "Flex Fuel" or E10, E20, and E85. The more alcohol you run in a mix, the more fuel the injectors have to be able to flow. I suggest as a test, you take two lawn mowers of the same make and horsepower and run them side by side, one using pure gasoline and one using pure alcohol, using identical volumes of the different fuels and see which one runs out of fuel first. Actually hooking up the lawn mower engines to a generator of some type to generate some load on the engine, you won't be able to run the alcohol fueled engine without jetting it up and when you do jet it up and get it running, it will run for almost half as long as the unmodified engine. You'll have to change the ignition timing on the alcohol engine because alcohol burns slower than gasoline or you'll end up burning the valves on the alcohol engine. What I'm stating is not some kind of theory or belief, it's a time honored group of facts well established through over 100 years of practical experience by millions of engineers, mechanics, and hot rodders. Sorry guys ... you just aren't correct on this one. I really really like your show and think it would be really fun to do what you do.
BUT cellulosic alcohol can come from veggie/tree food scraps, animal poop??.After storms loads of branches & trees come down across towns & cities,, all can be made to fuel flex fuel cars
it is because of the car mercedes can run with stones :D
@markus24q
This cooking oil fuel is a lot more viscus than normal diesel fuel. Common rail runs on up to 11000 PSI VS 4000PSI for a normal Diesel engine, which will of course lead to serious problems when run on the viscous Bio-diesel
sounds good
Should be converted to biodiesel first using transesterification. Simply using unmodified cooking oil will destroy the engine after few months.
Rubbish. I have been running my Toyota Landcruiser on filtered vege oil for about 6 years now. No difference in power output or efficiency. The only modification to the engine is a FPHE before the IP. Runs perfectly. No need for bio diesel or any other processes.
Gus Fergy Please clarify..what is FPHE and IP? New to this and am suitably amazed
***** , He might be just misinformed rather than full of shit. I know as FACT that it has not destroyed my engine. Maybe he has had a bad experience or used it in an engine that didn't like it and made his comments as a result without proper knowledge. Who knows. Who cares. Not me. I run my cruiser on vege oil and it goes great, that's all I really care about.
***** Sorry for the late reply. FPHE = Flat Plate Heat Exchanger, IP= Injector Pump. No need to be amazed. Its very old technology that many people still use today.
Thx. Been looking into it and sounds feasible and easy. Saw a doc where islanders used coconut oil in a diesel toyota.
Don't understand why they were surprised. Mr. Diesel's used peanut oil to run the engine that bears his name.

so no wars were fought for that cooking oil, no harmful pipelines were built and leaked for that oil , no ocean life was ruined due to offshore drilling, no one's health was effected for that vegetable oil , the air is cleaner with that oil due to less green house gases released - this oil can be recycled from our food- hemp can also make oil and the rest of the plant can replace fibers,pulp,plastics and it still make food and grows in under 3 months !! #votegreen and let's get some stuff moving in the right direction !!

Generators will also run on cooking oil, which charge electric motors. So, imagine the miles on electric engines charged with cooking oil. I am thinking hundreds of miles, maybe?
+Xylius Schaaij
It would work though, right? If no diesel was available, or you had a stock pile of vegetable oil during a power outage, the oil could power a battery charging station. Im uncertain, but perhaps the least expensive method would be solar, wind, or hydroelectric power in the long run, if there were enough batteries, but then there is the cost to manufacture them. I figure the lifespan of a diesel motor would outlast the life of the batteries needed for an electric motor. Diesel overall sounds like the most efficient fuel source for a motor vehicle.
+Xylius Schaaij You forgot that the diesel generator have about 25% on diesel to electric energy convertion.
+Guy Warner
Are you saying that only 25% of the energy is converted into electricity, and the rest goes to waste?
Yes. Goes of in form of heat, sound and friction. This in the engine that will turn the electric generator, and the generator will have a 90% of efficiency, after that the electric car will lost energy when charging in form of heat, and the electric motor will have a lost to but electric motor can regenerate energy while braking or when they are reducing the speed. By the way... Its how this works. We burn coal, natural gas and diesel to generate electric energy.
This is the so called Carnot cicle.
I tried the vegetable oil route for a while. It works as advertised. However I have heard of a few folks who wrecked their injection pumps because of the high viscosity - you should heat the oil to 180 degrees. Below 100 degrees the fats started to solidify and plug the filter. I found myself not being able to get the system going in the morning. You need a heater IN or ON the filter. Kudos to those who do this but I ended up deciding $3-4 a gallon at the pump is worth what you pay for it.
I was also wondering what modifications, if any were necessary to switch the vehicle over to straight fry oil?
bad representation of the filtration process. with pumps this can be done very quickly.
How was this "myth" "busted?"
You CAN run a car on used cooking oil but it's not as efficient... But it IS free... sort of.
We essentially have an endless supply with the right infrastructure in place.
@drogoKoJ and yes the first diesel engine was run on peanut oil. He was also interested in using coal dust and vegetable oil.
also you have to remember the engine was already nice and hot from the diesel when they tested this. my unmodified golf runs perfect on SVO when hot, its just getting it to start when cold thats the problem.
I stopped watching these guys when they started doing experiments that I've done that works that they said didn't and made it look like it was a scam and it was not a scam.
Idi's love soybean, peanut and canola oil.
The Ricardo Comet combustion chamber delivers the best swirl action for these fuels.
congrats give yourself a round of aplause
This test is extremely unscientific: To produce that vegetable oil (I'll assume that it is soy oil, as it is the most common) was used diesel to run the trucks and tractors!
To anyone that wanna to study this matter of fuel, energy and efficiency I totally recommend the Patzek and Pimentel's works, go and study them carefully, you won't be disappointed!
The Mythbusters tested if a diesel engine could run on untreated used cooking oil. The test was a success, it did in fact work. The process to create any cooking oil, vegetable or seed, can be inefficient, whether environmentally or economically...but the bigger picture tells a different story.
The cooking oil is most probably trucked to restaurants, which in turn can power the trucks, and the farm equipment. There will always be used cooking oil if someone wants fries. Why not recycle it, and use it as fuel? It's economical and efficient since you're using what has already been produced.
As far as I know, used cooking oil doesn't damage diesel engines if it is filtered properly.
The point isn't whether it functions or not, of course it functions; (the first diesel motor engineered by the German inventor Rudolf Diesel was devised to function on peanuts oil).
There's at least two unfair points, that could fool really a lot of people:
* The effects in the long run wasn't tested, as it could damage the engine;
* The production of the vegetable oil uses diesel from petroleum, so it isn't a "renewable" source of energy.
Of course if the economic conditions permit, one can and must recycle the used cooking oil, but it isn't economic viable all the times and in all situations.
Thank you for your time and best regards!
baianoise It's just mythbusters, thjey don't dig very deep. Your right there is problem with cooking oil, it's a lot thicker and a lot of people recommend to heat it up before use. Using dirty cooking oil that is 'filtered' would be something I only would do with a old diesel car.
To be honest, nothing is renewable really, when we using machines powered by fossil fuel on one way or another. The thing is using a waste product will use less fossil fuel then just wasting it. Where are not going to stop use fossil fuel until the it is so rare/expensive that it's cheaper to grow different crops to create bio fuel.
baianoise dont see your point since they are just reusing use oil thrown out so your agruement about the stuff use to harvest it is in valid its a stuff that is gonna be thrown out anyway and reusing it as fuel is not such a bad idea though using unuse veg oil which your pointing our is kinda wasteful but using use oil is not wasteful using something that people throw out is not really a bad idea
Felix Jr Lim Well, these question are really trick because they aren't very evident at a first glance; we should ask ourselves:
- What is the point in use the waste cooking oil?
Answer: we use for the sake of its energy content, not for itself. For a energy source be profitable (in the energy balance sense not only in the economic sense, as the government subsidies sometimes pervert the laws of physics and "magically" turns a non profitable energy source in a profitable one) it must deliver more energy in it's use than the summation of all energy inputs used in its production and/or extraction.
In that case of the used cooking oil, its energy inputs was:
- all energy used in the sowing and harvesting of the grain, his processing till the extraction of the oil, its filtering degumming, etc
- the energy used in the cooking of oil, be it electric or from natural gas, coal, etc.
- the energy used in the transportation of oil to the fuel processing facility.
Now imagine it in a national scale, millions of cars using that sort of oil?
I agree with you that, in the strict economic sense, from the point of view of the people who took the oil from the restaurant (specially if it was at no charge) and burned it in his car, it was indeed very advantageous, but the economy can't change the physical reality: the thermodynamics calculations, as we have spent more energy than has been delivered.
Sorry for the long answer, and I hope that I have been clear.
