veg oil

[BDG]

Filter it for what? If he is using it unused, it does not need filtered. If it is used, better off turning it into Biodiesel as it will have that much water in it that it will stop an engine anyway. Will have to filter the burnt food out, dry it as best at possible then react with the methanol and sodium hydroxide to dry it further.

Better off getting an engine that can run on the oil fresh from the shops, veg oil is jut under 90p/liter. If I was running 100 veg full time I would put a second tank in, warm up the engine on diesel, have veg oil pipe work around exhaust manifold to pre-heat the oil and a switch to go from one to the other.

Warm the engine up on derv, switch to veg. When you pull up, switch back to derv, make sure engine runs on long enough to pull derv through so it starts on derv. Change oil more frequently as veg contains lots of acetone which will break the engine oil down (and seals in some cases).
