Best gas?
 

What brand of gasoline do you normally fill up with and what do you find is best? In my '07 Elantra, I like to put in Chevron with Techron, but I have put in Shell before too (regular on both). Is Chevron really that much better do you think? I've heard the Techron is recommended by many mechanics. Thanks :)

A lot of people have different theories on this issue. I pay attention to MPG as my measure of gas "quality". I've found Citgo and Pilot to be pretty good, and stay away from "Flyin J".
