Question

any one used veg oil straight in there diesel car, any cars that work, or people that can recommend one from experience, i know most cars you need to make the bio diesel, and have heard mercedes work.

Answer 1

it works in all diesel engines ,it is about 15pence cheaper,only draw back is only a few out lets in GB.used more so in Germany.

Answer 2

They did a piece about this on Mythbusters. As it turns out, ALL diesel engines will run on used veggie oil without modification, provided you use between 1/8 and 1/4 (total volume) of diesel.

They succesfully ran 10 different diesel engined cars using this mix, with no power loss.

Answer 3

Mercedes are a good choice you can also use the Citroen or Peugeot but you have to really refine the oil and use 1/4 gallon of diesel to 5 gallons of used frying oil hope this helps

Answer 4

you would have to phone up a manufacturer of a car to find out. most cars will run on it but some dont.

oh, and you dont use pure veg oil, its used chip fat oil as its thinner and its also mixed with a substance to help get the motor running on it. you can actually go and pour oil down in your car, you do need to go to a garage that do bio diesel.

Answer 5

All diesel engines should run on the most amazing range of fuels, however regarding SVO (Straight vegetable oil) a lot of people on the biodiesel forums started running their cars on it, only to open them up 40-10K miles later and find a layer of glycerine on everything. Short term or a junker, mix with diesel. If not, find your local Biodiesel seller and use that.

Good luck

Answer 6

None of them without serious modification. Vegetable oil is much thicker than diesel and can't be used just straight. If heated to over 80 degrees and put into a prewarmed engine it may assuming you have modified the lift pump to pressure it up to the right pressure to atomize. Of course, in the winter it's even worse, and will cause problems even more then.

Answer 7

Rudolph Diesel invented his engine because he wanted something that would run on peanut oil. Otto's engine (spark ignition) needed fuel that was more volatile.

The problem with biodiesel and vegetable oil isn't engines, it's manufacturers' warranties. They won't fix the engine for free if they think they can prove that you broke it.

Merc have gone further than most in testing the performance of their engines with various types of biodiesel, and I think the result is that they offer less restrictive warranties.

The other manufacturers offer warranties on a blend of 5% biodiesel (transesterified veg oil) with fossil diesel, because that's all that the EU obliges them to do.

There are a lot of enthusiasts making their own biodiesel, either by filtering waste cooking oil or going the whole way and running their own transesterification processes. Find your local enthusiast (internet, chamber of commerce, renewable energy association, energy institute) and chat to them. Most of them are farmers, or at least vaguely agricultural - the sort of people who are content running messy processes by hand.

I'm a city boy, and my car needs petrol. Sigh...

Answer 8

Mitsubishi 'Pajero' run sucessfully with up to 80% vegtable oil for almost a year with seemingly no ill effects. Sold about 8 months ago and still seen occasionally.
P.S. This was normal vegetable oil bought in (usually) 3 litre bottles from supermarket

Answer 9

you are able to replace oil AND filter out each and every 3 to 6 thousand miles. the difficulty with not doing that's that oil gets grimy, even with a filter out and the combustion technique contaminates the oil with acid. permit it pass long sufficient and the filter out clogs so there is no filtration of airborne dirt and dirt and steel debris and the acid builds to the point that it eats away engine aspects greatest to early engine failure. while you're having to characteristic oil often then you definately the two have a leaky gasket someplace or the acid and airborne dirt and dirt have worn aspects to the ingredient that your engine is burning oil. in case you notice a bluish smoke popping out of your exhaust you're burning oil.

We run our cars (Audi and Volkswagen) on rape seed oil,grown in our own field. It's taken away after harvest,refined and brought back in a large tank.You can , and we have used it for cooking.
