How to make Bio Diesel from waste cooking oil

[Jbird]

Does anyone know the process used to convert used cooking oil into deisel to run my car?

Here you go

The only problem you'd encounter by just filling up today is getting the engine started. This crowd show you how to get a conversion kit to allow that happen.

Another option is a second tank with a swtch - you start the engine with diesel, then immediately switch to filtered vegetable oil.

Note though - you'll invalidate any warranty on your car if you make the change.

There's a link on that page too about the legality - it's all to do with volumes used apparently - but read this too

Thanks I'll have a look at both - I'm not worried about warranty, its an S reg!!

i seen this on Top Gear one night. They tried both clean cooking oil straight from the bottle and disused oil from a chip van. According to them the dirty oil ran better than the clean oil!

Surely cooking oil is more of a fire hazard then diesel?

Er, no.

I ran my old vauxhall diesel regularly on a 50/50 mix of sunflower oil and diesel. Sunflower oil was 49 pence a litre from Lidl until recently. Now it's �1.20 a litre so it's not worth doing now. The car ran lovely. The only downside was an overpowering smell of doughnuts from the exhaust. You know that smell you get from a seaside doughnut van? It used to follow me all the way to work.

Used cooking oil surely contains particles of fried food which if you don't filter out would clog up the fuel filter. Cooking oil is dense stuff so how do they filter the impurities out of it? It's not like filtering coffee through a paper cone.
