How many miles per gallon does a 93 ford explorer get?

The fuel economy of a 1993 Ford Explorer varied significantly depending on the engine and whether it was a 2-wheel or 4-wheel drive model. You won't find a single MPG figure that applies to all of them.

Generally, expect figures in the range of 15-20 MPG combined (city and highway). Highway driving would yield slightly better MPG than city driving. However, actual mileage will depend on driving habits, vehicle condition, and tire pressure.
