hi. i recently bought a 88 4wd xtra cab 5 speed truck with 219k miles on it. its a real dog and gets horrible mileage. fifth gear is just about useless. it has 255-70-15 tires. i do like it though and am considering a newer engine with 120k miles on it. i wonder how much my mileage will improve with the new engine. i know it has to get better. i currently get about 10-12 city mpg. its a little low if you ask me. what do the rest of you get?
