High octains make your o2 sensors and cats go out faster... due to the dumping of unburt gasses into the exhaust system but if you are going cross country and will be doing 75+mph most of the time then higher octains are OK!

For that reason, I stick to Unocal, Chevron, Shell. But that might be overdoing it.
I see Arco stations close down for a month at a time, and I know they're not retrofitting their equipment every 12 months. But they reopen again 1 month later, so what is W&M doing? Slap on the wrist. It seems that Arco doesn't learn.
