I know you can use old cooking oil to run a diesel car, but i can't remeber what you have to add before you put it in the fuel tank!What do you have to add to cooking oil if you are going to run your car on it?
It depends on the engine, the latest common rail diesels won't like it however older type engines are fine my 4 x 4 is fitted with a pre heater to thin the oil prior to it being used I therefore can run 100% on veggie oil. However don't forget that you must register with C%26amp;E as you have to pay duty on what you use, if dipped you will lose your car and face a hefty fine. However the good news is that C%26amp;E are looking at the possibility of removing this requirement if you use less than 2500 litres a year, this should happen by this summer fingers crossed. The www.pocuk.co.uk site has some information on this on their Bio fuel forum.What do you have to add to cooking oil if you are going to run your car on it?
You have to mix it with methanol I think. And let it stand for a number of days. My brother in law used to run his car on it and I think it was Methanol he used.
Basalmic vinegar
You have to filter it and add 50ml of acetone per litre..
Some cars can run on Straight Vegetable Oil (SVO) without any additives. Some cars may need in-line fuel heaters.





When I had a diesel 4x4, I used a 50/50 mix of diesel and SVO.
you need to mix it with methanoll. but if you using old cooking oill you need to remove any water in it first by boilling it. then strain it to get any fine bits out or your car wont go anywhere!


your will also need to pre heat the oil in the tank on cold days it will be thicker and wont reach the engine. and register with hm customs or you will get a huge fine and keep records

avoid starting cold engine on high % veg oil. On long journeys its fine, just put diesel in at the end.
Your crazy!
fish and chips
talk to a mechanic....sounds fishy.
Food colouring, if you get stopped and the oil is checked and it is not the correct colour Customs %26amp; Excise will do you for the tax you have not paid. Not sure what colour, cochineal would do it.
