What gas do you guys use for the non diesel drivers on here? I try to use premium since the original tundras were premium only, and it has to be better for the truck, which i drive moderately hard, and want to last till 200k i assume regular oil changes and premium will help this. I was hoping the gas mpg would go up with the premium, and it did a little, but that could also be my driving as well (up from 11.6 to 13.3 on truck dash computer) However, gas is up agian, should i really bother with premium? What do you choose? why? discuss?
