I have a 1988 ford 3/4 ton 4 wheel drive truck with a 300 six,5 speed with overdrive. My ? is what kind of mpg should I get with this truck on the highway? I've never had it out of town since I bought it, used of coarse.

Around 15-16 if your lucky. Those 300's are usually geared fairly low and being a 4x4 is will surly cut your gas mailage. Road trip will tell for sure.
