I use Chevron or 76 but I have no problem with Costco gas. I just don't have Costco membership and the lines are super long for Costco gas. I try to avoid Shell if I can.
Not true, Costco does not refine their own fuels as they have no refinery assets, they contract with all major producers. You could get any one of the top brands at any given time. I have always preferred to stay with one brand and actually the same marketer of that brand. One of the big factors among most fuels is the ethanol content.
