Cheap gas has been cited for all kinds of problems, the most common being poor performance and knocking/pinging. If you Google "Costco gas quality" or something similar you will see all kinds of stuff.

I use Shell exclusively (because it's all over Houston) and have never had any gas-related issues. I just wish they'd take the damn ethanol out...stupid government regs.

Edit: Sorry for the thread jack. We can all go back to spotting M3s now.
