"No one buys crappy food for your car like Gasdon!"
This will find the most cost-efficient semi-edible commodities to refuel your car with. It is also a blatant rebranding of that thing for boozing up the driver in Dread. (With food in addition to booze, because every car deserves the cheapest garbage you can possibly find, regardless of which organ it fills.)
It can also crank out turns of the various driving modes, although newer versions of Mafia can do that too, apparently. This script should still work on older versions of Mafia that don't know what an Asdon Martin is.
gasdon (number) -> Fills tank up to at least that many litres.
gasdon list -> Show the top eleven cheapest fuel sources.
gasdon (type of driving) (number) -> Drive in the specified way for the specified number of turns. Will refuel if necessary.
gasdon [name of item, in brackets, like this] (number) -> Fuel up using only the specified item. Mainly so you can use this in-run without accidentally fueling your car with something you wanted for fueling your body.

Honestly, at the moment this doesn't seem all that necessary, since there's a lot of cheap food laying around. But if enough people use it, it could speed up the food/booze sinking process and end up making itself useful. The wheels on the circular justification go round and round...
