Late this summer or early autumn I'll replace my old Ford Fiesta with an older Saab 9000. My Fiesta is not worth more than a few hundred quid, so I thought I'd see how far I could drive it with a 50/50 mixture of cheap Olive oil and 20-50w, if that doesn't kill it I'll try pure Olive oil.

So what do you think Oppo, how far can I drive my piece of shit on such oil?
