If I supersize it, do I get a minivan?

According to Le Monde, a Marseillais man has modified his diesel car to run on used vegetable oil. He acquires it from local restaurants, strains it and pours it into the tank. The car has an internal "stove" to heat the oil up to 90 degrees; I believe this comes standard on all frying grease diesels. There is of course one drawback, a slight odor of said frying grease which follows you around. But hey, if you're employed by McDonalds you've already got that problem. No telling how many McDonalds will be ordering for their delivery fleet.

Shouldn't the Wienermobile be running on this stuff?
