Is it true that people are putting used cooking oil into their diesel cars?

Some one told me yesterday that her friend filters his used cooking oil and puts it in his diesel engine.





She said it smells like fish and chips when he drives down the street, she siad that lots of people are doing it now as it is a biofuel.


And she said its legal which I find hard to believe.





I dont think i will be trying it. But out of interest anybody esle use their ';Spry Crisp and Dry for this purpose?Is it true that people are putting used cooking oil into their diesel cars?
Hi





My mate pours ASDA smart price oil straight into the tank of his van without any modifications





He has now sourced a free used supply from a chippy, which he filters first





he reckons new oil smells like donuts


chippy oil smells like stale chips





Ok... you need to know what engines do and what engines dont run on unmodified





Bascially if you have a LUCAS injection pump FORGET IT





Bosch pumps can handle it Ok .... but some oils need preheating first to thin them or require a 50 50 mix with diesel or Bio fuel





We have been running a single cylinder diesel mixer on vegy oil on our extension build..... noticed engine is quieter





If you abuse the oil method, without care.... I agree things can go wrong and damage can occurr





If in doubt..... do without








Oh.... and its UK legal and you can do 10,000 miles before you have to declare any tax (SO I HAVE BEEN TOLD ??)Is it true that people are putting used cooking oil into their diesel cars?
It is illegal because you are avoiding paying fuel tax.


It is done, but the oil is filtered many times and is added to existing diesel engine fuel. I think you cannot use it completely on its own because it can eventually clog the pipes in the engine...I know some people are also using red diesel for boats in there cars as this is cheaper and less taxed, but again illegal. Its coloured red to distinguish it from normal diesel.
NO !!!





They have to convert the used cooking oil to bio-diesel FIRST. Otherwise you risk damaging your fuel delivery system and/or the engine.





Don't do it. Any money you save today, you'll end up using 10x on car repair.

Good Luck...
Yes its true i have been running mine on a 50/50 mix for two years and you can use 2500 lites per year with no duty due. however the supermarkets (Tesco) have raised the price of pura cooking oil from 68p litre 2 months ago to 拢1.08 a litre theiving buggers...
Yes it is called Bio diesel. But you dont just pour it into your tank it isnt quite that simple. You have to boil it ,clean it , and add ethonol. You can buy it at some petrol stations but i am not sure where.
Yes is it true, but old cooking oil is only being burnt in older deisel engines and then only when it mixed about 50-50. Newer deisel engines wont support this fuel unless mixed with the right amount of methanol and filtered properly.
yes its true...NO MODS in my brothers car,used chip shop fat strait into the tank...any body says it has to be chainged to bio fuel is talking bull...the vw 19 di engine burns it neat...
yes it's true but it is converted into bio diesel first
