Well for since march till now we've been using rapeseed cooking oil in the car roughly 10 liters of rapeseed to 5 liter of diesel, but as winters coming i'am just wondering, should i substitute the 5 litre of diesel with petrol to help thin it down and not freeze, it was an idea suggested me by lofty79 ages ago but just looking for some more opinions  please

pretty sure I read somewhere that veg oil can be thinned down with white spirit but I don't know what ratio of white spirit to oil.

Well any info is appreciated as it keeps some of the money in my pocket and not all in the Goverments as fuel duty
