* Specific trim level: Different trims (like a base model vs. a more heavily equipped one) could have slightly different weights affecting fuel economy.
* Axle ratio: Different axle ratios impacted fuel efficiency. Higher numerical ratios (e.g., 3.73 vs. 4.10) generally meant lower highway mileage but potentially better acceleration.
* Driving habits: Aggressive driving significantly reduces fuel economy.
* Vehicle condition: Proper maintenance (tire pressure, tune-ups) impacts mileage.
You won't find a precise number from a single source. To get an idea, you could try these approaches:
* Check owner's manuals: If you can find an original owner's manual for that specific truck configuration, it might list EPA estimates.
* Consult online resources: Websites like Edmunds or Kelley Blue Book *might* have some general fuel economy information for that year and engine combination, but it won't be highly precise. These sites typically focus on more modern vehicles.
* Look at used vehicle listings: Used car listings sometimes include gas mileage reported by the seller (though reliability varies).
Expect the combined city/highway mileage to be in the 12-16 MPG range, but this is just an educated guess based on similar trucks from that era. Real-world mileage could be higher or lower.
