Heiho,
depending on manufacturer a Diesel engine may work with vegetable oil without any hassels. Since MB was mentioned I'm pretty sure it did no harm to my elderly one (has run about 330,000km with still its first engine, about 80,000 of them with rapeseed oil), neither did it to a MB Trac. I'm speaking about vegetable oil you may buy while doing your grocery list, preferrably rapeseed oil. I've also seen a report of someone using used frying oil as gasoline in TV some time ago. This ofc needs filtering to get rid of the crunchy bits, and depending on the frying oil it'll maybe need preheating.
There is 'Bio Diesel' gasoline around, and for usage of that the engine needs some refinements (again depending on manufacturer), since the difference of Bio Diesel to vegetable oil is mainly an enhancement which prevents the oil from going stale/rancid. Unfortunately the necessary additives/chemical process will lead to stress for the motor's valves during the burning process and eventually destroy them without aforesaid refinements.
Your car will smell like an exploded fast food place for sure.
