hi,anyone out there using biodiesel?i have looked this up on the net and i understand you can make your own from veg oil and run your car legally up to 2500 litres before you have to declare it to the authorities.cheers rick.
I wouldn't have thought our government would let anybody get away with tax, check first before you go into full production!
It seems quite simple to do...

My brother has run his car on it for about 5 years he collects old frying oil from varies places who are only to happy to get rid and strains it through 2 tea towels then bungs it in his tank
I looked into this when I was buying a car and I'd recommend getting expert advice before chucking old chip fat in the tank. Apparantly the newer common rail diesels are not suitable and you will end up with a very large bill!

Thanks for the advice but my bro is a self made mad professor done a lot of research fitted his own system in 2 cars one which heated the oil in winter to thin it out and he don't believe in modern cars he's got an old L reg CITROEN Xantia with split fuel tank small one for diesel and fills the main tank with veg oil
you can put chip fat in cars BUT you have to modify the fuel slightly, or modify the fuel system in the vehicle to heat the vegetable oil before it reaches the injector pump. Some engines adapt more easily than others. Some engines seem to run on straight vegetable oil without any need for adaptation at all, for example Mercedes 123 and 124 series.
Generally, you need to filter the fat to get the bits of chip etc out, then you add a solvent, which thins the fat out making it flow better, and also acts as a detonator. theres all sorts of solvents you can use, but turpentine substitite works well. Then you let it stand for 6 weeks, and rack off the nice clear stuff from the white crap at the bottom.
Theres a lot more to it than this, but you get the idea.
