Costco or Sam's Club Gas?

[sailing1]

You are pretty much right in that most of the gas at pumps is pretty close. A friend who is an engine tunner says the thing you really need to watch out for is the freshness of the gas. We don't have a Costco here in Oklahoma but I would imagine that Cosco runs enough gas through the pumps to not make that an issue.

What gas station is your preference in Oklahoma?
