Which fuel is best for a 2000 ford taurus?
A 2000 Ford Taurus should use regular unleaded gasoline. The owner's manual will specify the octane rating (likely 87), but using anything higher won't provide any benefit and is a waste of money. Avoid using anything other than gasoline; it's not designed for ethanol blends higher than 10% (E10) and definitely not for diesel or other fuels.
