Peugeot on Vegetable Oil?

It seems to me that this is way beyond what a food science group can advise 
you about. I can tell you that used frying oil will contain peroxides and 
polymerised oil, but what effect that would have on an engine I can't say. My 
gut feeling is that you can't just put your oil straight into your car and 
expect it to work perfectly. I think you need to talk to a few automotive 
engineers and diesel mechanics.

I also seriously doubt that you can pick up frying oil for the same price as 
diesel, unless you happen to know someone who runs a fish and chip shop and is 
willing to give you their used frying oil. That, I suspect, is the real reason 
biodiesel hasn't taken off yet.
