Walked out of tescos today and saw some guy filling his land rover up wiht a drum of cooking oil he had just bought. Was funny looking at his wife hiding in the front seat!

that shit really works?!?!?!

yeha i know a bloke who goes round getting used chip fat from chip shops/restuarants/pubs etc and after running it through a few chemicals he sticks it straight into his diesel 406. saves soooo much money on fuel and it is actually better for your engine then runing petrol thro it! the only down side is people think your a terrorist when you try and buy the chemicals!

25 litre drum of cooking oil from Costco... £17

25 litres of diesel from Shell... £32 or so

What sounds best?
