Go to the Arco down the street. Sometimes it's cheaper. Otherwise same price. And you don't have to wait in an hour line. Only a masochist would try to get gas at Costco!
Yes. The mixture of gas is actually regulated by the state so all brands are 99.9% the same due to regulation.
Costco has methanol 10% I get 10% less mileage using Costco gas
Yes, it's comparable quality. It's rated as top tier gas.
Costco gas quality is lower than chevron shell or valero. But comparable to arco or lit less. My car gives low miles if filled with costco almost 90 less miles on full tank than valero
Costco is good
Costco is as good a quality as anyone else. Though they only sell 87 and and 91.
