Here is a follow up on a discussion we had previously about which oil company is the best for filling up your car. Right now, I go try to go to Sunoco most of the time, although I will sometimes use the Exxon card if there isn't a Sunoco nearby. The gas quality for Sunoco seems to be ok for both my Ford Focus and Jeremy's Cougar and I was happy to see that they weren't one of the "worst" companies on Sierra Club's list. Which gas company do you use?
