I have a '95 and now a '96. Both get about the same mpg you do. Even with changing the plugs, wires, cap, fluids and filters you are only gonna gain 1 or 2 more mpg. I spend about $200 a week in fuel just for my '95, either you learn to live with it, or you get something you can afford. Save up some $$ and get a beater 4cyl and park your truck for a while if you want to keep it, then if you get a better paying job put the truck back on the road. If you're only making $150 a week, a truck isn't for you at the moment.
