* Engine size: The 1994 Explorer came with different engine options (e.g., 4.0L V6, possibly a smaller inline 6). Larger engines generally consume more fuel.
* Fuel tank size: While generally around 15-18 gallons, the exact size might vary slightly depending on trim level.
* Driving conditions: City driving significantly reduces fuel economy compared to highway driving. Factors like terrain, speed, and even weather can affect mileage.
* Vehicle condition: A well-maintained vehicle will achieve better gas mileage than one needing repairs.
Without knowing the specific engine and tank size of the *individual* 1994 Explorer, it's impossible to give a precise answer. However, you could expect a range anywhere from 200 to 300 miles on a full tank, but it's best to consider that a rough estimate. To get a more accurate idea, check the owner's manual for fuel economy ratings (in MPG) for that specific engine and then multiply by the tank's capacity in gallons.
