Alternative Fuel / Veg Oil

[Stu C]

Hi folks, just wondering about this after i went to a logistics conferance talking about alternative fuels.

Chip fat. I know it can be used in diesel engined vehicles, but how much exactly and what damage can this do? I do a alot of commuting now, and was wondering, you know, would putting in some veg oil with the diesel do any damage to the car? (sorry its not a volvo, still on the ol' 600 )

Cheers all!

Regards

i run my 2.8 td trooper on a 50/50 mix, 8000miles and no probs so far, i know the newer machines with fancy ecu's dont react well to it but if you have an old machine try it, i started of at 10/1 and worked my way to 1/1. exhaust smells lovely

Do you pay Duty on the veg oil ?

My sisters partner has a ex post office van that he uses to go all over the country, he came here the other week and told me he was using Veg oil so i took him into the Indian community shops and he bought 30 ltrs of veg oil at £12.99 he chucked 15ltrs straight in on half a tank of diesel no probs at all, but he has since told me if he mixes it with not enough diesel it is hard to start up, as i suppose the oil separates from the diesel.

Ahh cheers for the replies all! been reading up on the subject like, and alot of people stik between 10-20 litres of veg oil to diesel (mine being 65 litre tank) and are running fine. May try a little bit over the weekend, just a 3 litre bottle and see from there

Correct me if I am wrong but I was under the impression that the veg oil/chip fat had to be used. It can't be a new bottle from the supermarket.

I have got a deisel as a runaround and was considering it but don't know enough about it at the mo.

Either will work it just so happens that used stuff seems to work better - once you strain all the chips out of it

You will need to run injector cleaner in every few tanks with used veg oil due to the carbon particles in there from burnt food which could clog up your injectors over time.
Also if the oil is too old it produces "polar compounds", basically fatty acid chains split off from the tri glyceride backbone of the oil molecule. These can polymerise and increase viscosity of the oil making it difficult to mix and can get a bit sludgy.

Who said being a Food technologist was no good for car stuff.......

I'm running pure bio-diesel at the moment. I'm paying 60p a litre to my boss who's buying 1000 litres at a time.

My little 106 is doing 54mpg and running sweet as a nut.

Its made form recycled cooking oil, I believe.

[Andrew]

Is bio-diesel what they call red diesel ?

[Redbrick]

No not the same thing.

ah ok thanks.

Word of warning modern common rail injection systems are not very tolerant of "funny" fuels (pumps and injectors can get clogged muchos money to replace) so only try this on older cars.
