Let's look at some cold hard numbers:

If you travel 15,000 miles in a year, and get 10 mpg, you'll buy 1500 gallons of fuel costing $2,250 @ $1.50/gal.

If you buy a 7 year old honda civic for $3,000 and get 25 mpg you'll save $1,350 a year in fuel over your truck. But look out for that maintenance bill. Parts are not as cheap. (or get a $1,500 Mitsubishi Mirage and only take a year).

Based on that, it will take you two years to recoup in fuel, what you spend on a more fuel efficient vehicle. This is the basis that I didn't spend 2k on fuel injection. Granted after two years, you'll be loving that easy fill up at the pump.

If you tune your truck (not knowing what gears, engine, carb) and keep your teenage foot at bay (not easy) and get up to 14 mpg (can be done) you can shave $600 off your fuel bill.

Just do the math and look at the tradeoffs before you leap.
