Mileage questions

My totally stock '91 4.0, 2wd automatic on 29" tires gets a pretty reliable 17-18mpg on the highway as long as I go 70. The Comanche has pretty bad aerodynamics and your fuel economy will be punished heavily at higher speeds because of that.

 

The 2.5 doesn't get that much better mileage that I would specifically look for one (somewhere around 20 mpg usually), and the 4.0 is much more powerful, but with that said the 2.5 is sufficient for a small truck. Both the 4.0 and 2.5 have a similar reputation for toughness as the 300 I6 you have now and produce excellent power for 25+ years old trucks.

 

1991 or 1992 trucks with the 4.0 have the best parts availabilty, power, and "out of the box" reliability.
