Valero fuel in your area?

[roxy1]

my opinion is when one tries something different and thinks might result in better mileage, it is easy to subconsciously drive in a more efficient manner, thus kind of a self fulfilling prophecy. i honestly dont think the shell vs valero 100% gas would make much of a difference. i could be wrong. i thought i was wrong once many years ago, but i was mistaken.

but, dude, seriously, if you want the best mileage and to add 40 hp to your yaris experience, find some 95 octane!!
