When I drove my stock 235, 58, 1/2 ton back in college (87-93, please no comments, I was working my way through school

), I kept track of the mileage. I got around 12 mpg in mostly city driving and 16 mpg on the occasional highway runs home. 16-18 mpg is what my grandfather reported he got on the long drive each year to see his mother in Mollala, Oregon.
