Just out of curiosity, has anyone actually tried running their car on vegetable oil without modification?
My lodger is a car dealer and he bought a Pug 206 at the auctions that he has only ever used vegetable oil in........without modification
He did it as an experiment as he bought it so cheap and didn't care if he blew it up.
He's had it for around 4 months now and apart from a longer crank time and a bit of smoke at start up, it runs as normal.
I suspect come the colder weather the starting problems will get worse...........
