Im looking at getting a 1993ish Toyota 4runner (May be a few years older or newer, but generally this area). Im wondering how much it is to fill the tank, and how long it lasts. Or how its mileage is in general? If you have a 4runner, just let me know 
Also, would they be more fuel efficient than a V6 Commodore? Assuming it was a 3L 4runner?
