  • 50 miles to the gallon............ yet the odometer is broken. Must be judging by how high the fuel gauge is after 10 miles. Because we all know how reliable Mercedes fuel gauges are, right?

  • Do grease fueled engines perform well in the winter?

  • 50 , 50 ,50 MPG ! YOUR KIDDING , RIGHT ? your car is heavy i would guess 25 , 30 tops . i have been running WVO for years i have 3 cars .85 volvo 740 diesel auto trans 32 mpg . 84 volvo diesel man trans 38 mpg and a 82 isuzu i mark diesel that gets 50 , its like driving a tin can ! and your big heavy mer is getting 50 ! who you trying to fool

  • I might be moving to Las Vegas. I have a diesel Mercedes just like his. What would be the best plant to grow for vegetable oil/fuel in a desert region?

  • I have that same exact car in white. How come he doesn't use the fuel "pre-heat" system so the vegi-fuel will burn more efficiently?

  • waaaaiiiiit a minute....50 mpg? How is your ALDA tweaked? Any engine modification? Regardless of the fuel's thermal efficiency, I doubt the OM617 could produce 50mpg and be drivable. Even with extreme hyper-miling (which, btw, can be extremely dangerous) the best mileage I've been able to squeeze out is between 34-36 mpg with a properly tuned engine. Most VO people report slightly worse mileage in properly tuned MB's. Something is fishy....

  • Its known as lying, which you are doing too. The OM617 is not physically capable of 30+mpg.

  • Wrong. 50mpg IS lying. I get 29 mpg under during what most people consider "normal" 65+ mph highway driving. My commute consists of a 2 lane highway, 50-55 mph, with heavy truck use--meaning you can slipstream them SAFELY, basically ideal mpg conditions. I've hit 34-35 three times so far. I guess it would be "physically impossible" to get the 42 mpg I got this week in my gf's eclipse too. Or the 55+ in our TDI. FFS Learn how to drive before being an asshole.

  • Learn some basic physics before making yourself sound so retarded next time.

  • Seriously? Get the stick out of your ass. Less wind resistance + ideal conditions = better than normal mpg. I'm not saying I get 50mpg, I get 34 on a good week. You also had no reason to attack me. Get over yourself.

  • Key words there: "better than normal".

    Very few people are dumb enough to slipstream a semi.

  • I'm not talking about tailgating it. If you ever drive an SUV or minivan normally behind a truck you'll get blown around because you're entering the slipstream, its not really that close behind it when you can see both mirrors....Regardless, the 50mpg this guy is talking about is complete BS.

  • Of course it's possible. I drive a Peugeot Partner minivan and consistently get 52.5 US mpg. My Peugeot Partner has an indirect injection diesel engine just like the Merc and is made from iron. I've had great success with Biodiesel (made from wvo), SVO and regular diesel. For European and Japanese family cars, anything below 47 US mpg is pretty pathetic. My parents drive a Honda Jazz (JDM) which gets 71 US mpg on the highway in normal driving without resorting to hypermiling.

  • Do you really get 50 mpg in that car? Thats pretty incredible mileage for that car. My 240D on WVO was getting around 34 or so, and my 300D turbo gets upper 20s on diesel (have not put in the WVO system yet...)

  • I want to see the director cut of this video where someone runs off with your camera as your doing circles around the parking lot

  • ibenzawla I think you need to check your odometer if is not rolling fast, really 40 MPG, Is not possible...

  • What's it like starting it cold?  Did you have to do any conversion to the engine or just pour it in?

  • so, how can you say PO has slightly less energy than diesel and then later say it has greater energy than diesel? doesn't make sense.

    The only reason why plant oil or other related alternative fuels are discouraged is because we as a country don't have the physical means of sustaining that fuel source. We can't grow enough to fill every car/truck/boat/plane/train etc. for even a day. Besides, you can't grow crops on the same plot of land, harvest after harvest. The soil wears out eventually!

  • I never said that plant oil has less potential energy... It has more. There are limitations for land plants. For example, every acre of Australia would need to be cultivated with jatropha to solve the world's fuel problems. The answer, I believe, is algae oil

  • The answer, we all know, is you are full of shit and have no clue what you are talking about.

  • Suppose you added gasoline to diesel. Is there more Potential Energy? How about kerosene? Would you get a different MPG using those mixtures? I don't. There is too much "play" in the workings of an engine to get results based on the chemical structure. But if you are right, stop playing with us little-people and go out and sell your vision! You could be the next Bill Gates! (and I will not ask for a motivation-fee...)

  • @DeltaJet757 there is a double side to your argument,algae is the fastest growing plant in the world,can be scaled to be grown vertically and the water recirculated after the algae has been harvested from it.all it needs is sun and carbon dioxide which we have in abundance.sorry i seen you posted this 2 years ago so maybe you have seen this about algae since then.

  • you're a fucking retard. a w126 Benz is way too heavy to get anything near 50mpg.

  • Wow... Who is feeding you this shit about 50 Mpg, seriously, this car weight 4000 pounds, and its aerodimically impossiable to achive such mileage by the way it like almost driving a BRICK!!! your minds are fed by false information tell me where did you get this SHIT info, And by the way you guys are ruining your injectors and injector pumps as we speek!!!

  • maybe a metric gallon...

  • Would a 1979 300CD run on canola oil fine without any modification?

  • Not at all. You need a two-tank conversion.

  • Thanks, I have run waste motor oil, which offers better fuel economy than diesel. However, plant oil, particularly palm, jatropha and olive oil, offer even better fuel economy than waste motor oil.

  • Waste oil contains metal particles from engine wear that can damage your injection system. Its also VERY bad for the environment and illegal.

  • 50 MPG is Pure Bull Shit, this car dose not give 50 MPG on plain vegy oil, the best it could give is at least 30 MPG and no higher, there is no way in the world that you can achieve such high fuel mileage just by using cooking oil...

  • I'll make a bet with you, have you meet me here in California and happily take your money.

  • If the odometer is broken how do you verify the economy? I'd bet $100 you pulled the 50mpg figure out of your ass, that kind of economy is physically impossible in a 300SD. Just because its a diesel does not mean it gets stupidly high economy numbers.

    Its a 4,000lb luxury sedan with a 3.0L turbo engine, not a 1,500lb VW with a 1.6L engine.

    30mpg is the most it can possibly do on ANY fuel.

  • Certainly, measuring distance by GPS or map is beyond you because, at best, you have a degree in English, which makes you think that you are intelligent when you are not. I have a Master's in mechanical engineering from a top tier university, so I think that I can measure fuel economy without an odometer. Again, I'll wager all of my earnings in plant oil industry during the last two years, $2 million, that the car, a 1983 Mercedes-Benz 300SD, achieves that fuel economy.

  • That "master's in mechanical engineering" obviously isn't worth shit for you since a 300SD is physically incapable of getting that extremely high economy. Anyone with even a basic understanding of the car and high-school science can see that.

    Since you are willing to lie so grossly on your car's economy I know that 2 million figure was pulled out your ass as well.

  • Funny guy. You are correct that a 300SD gets 30 miles per gallon on DIESEL. However, there is more potential energy in most plant oils versus diesel, therefore a 66% improvement in fuel economy. People are out there making mountains of money with this knowledge.  Please continue to kick back and tell us what an expert you are.

  • More proof you haven't a clue what you are talking about.

    Vegetable oil has LESS energy per gallon than diesel. Using a high percentage mix of VO will actually REDUCE fuel economy over diesel!

    Seriously, stop spewing your lies before some fool actually believes the bullshit your are putting out.

  • Well, all that I can suggest is that you do your research... by actually researching and not sitting on your ass. I seem to fill in all of the gaps for you, and you still don't get it. If you are so correct and I am wrong, why don't you come out here to California and take my money?

  • All I can suggest is for you to stop lying. You are not filling in any gaps, you are making up your own bullshit and throwing it on top. Seriously, either you really have no clue what you are talking about or somebody fed you some BS and you believed it.

    The only person here not getting "it" is you. For claiming to have a "master's in mechanical engineering" you sure need to get educated on this subject.

  • I'm amazed there is a second person that thinks they can actually get 50mpg. Review your laws of physics people, 50mpg isn't possible in a Mercedes Diesel unless you can figure out how to pull 1,500lbs off the body and swap in a TDI from a VW.

  • That is false information. Please do not misinform the public about plant oil.

    Jatropha oil contains 121,000 Btu per gallon compared to 135,000 Btu for diesel fuel.

  • Yeah, uh huh, its all a Big Oil conspiracy to keep alternatives suppressed.

    VO can be a viable alternative alternative to very few or a supplement to many. Its not possible to produce enough plant oil to replace even a fraction of the world's daily consumption.

    The FACT you haven't a clue what you are talking about is actually very funny.

  • I find it extremely difficult to believe anything from somebody willing to lie so much about their car. You can research all you want, that won't help you weed out the BS put out by people like you that are willing to lie about anything.

  • U guys are too funny. If a 300SD could get 40 mpg, the price of those cars would skyrocket. I cannot but veggie oil under $2 a gallon.... and the $1 million a year salary would allow you to advertise on another media instead of U-tube. Get real: Veggie oil is too heavy. 300SD needs to be rebuilt to achieve 30mpg on diesel. And, I am under paid! I am going to convert one of my 300SD's to veggie oil if I can get enough free oil. Then I can give a true report.... But I would expect 28mpg.

  • Even 28 would be on the very high end for a 300SD on VO. 22-25 would be reasonable.

  • OK, and being real, 20 mpg on free oil plus some refining ($1.00 per gallon) is still a good deal. HEY!! Maybe the "50 mpg" guy is getting that number with fuel at a 75-percent discount! It would then be like getting 50 mpg!!! Still, FoodLion is not selling a gallon of VO at less than $2.00. People....

  • What you do is pick the oil seeds and press the oil. I live in California, and I use jatropha and palm oil. Poplar and willow oil are available in colder climates, mesquite oil in Texas. Look up "biodiesel harvest" on youtube to see what I mean. The best mixture is 90% straight vegetable oil and 10% ethyl alcohol (rubbing alcohol). I am not joking about my 50 MPG. I sell oil presses if you need one.

  • We know you are not joking about getting 50mpg, you are lying about it.

  • Well my 84 300sd gets very close to 40mpg highway with some city driving without any doubt.

  • There is plenty of doubt because that isn't possible.

  • Well unless my odometer is not working right or I am not calculating it the right way. Right driving habit, car in good shape and the right kind of diesel I'm pretty sure that this car will give you an outstanding mpg. I save a lot dring this car especially on the highway.

  • Thank you. Part of my extra fuel economy can be attributed to higher potential energy of plant oil over diesel. But like your car, mine is also in extremely good condition. I recently did a compression test that indicated original factory spec.

  • "Outstanding" mpg is anything between 25-28mpg. 29-32mpg is extremely rare and will never be averaged unless you ONLY drive on the highway under 55mph. 35+mpg is physically impossible.

  • @zech007 i have had 20 mb,and the best you're going to get from the corn,peanut oil etc instead of diesel is about 7 more miles to the gallon,MAX.

  • @zech007 Excuse me, I live in Europe and here there are a lot of cars capable to run up to 33km/l, that is about 77.5mpg.

    An old car like the 300D can arrive to about 20km/l (47mpg) running slowly and on a plain road.

    However the diesel fuel contains more energy thjan plant oil, and the mileage of the plant oil was comparable only because of the more complete burning, but normally the fossil fuel mileage was better.

    I run my car on plant oil since 2003, and I do some experience with that.

  • lol

     don't tell anyone cause the price of Vegetable Oil's gonna skyrocket!
