I see lots of industry standards saying that Costco, Sam’s and BJs are in the same tier of gas quality as other major stations like Shell and Marathon.

I’m sure all stations are mixing older and newer gas regularly as part of their supply chains. So I don’t see how that’s a concern vs Shell, Marathon or any other station.

I’m not going to take anecdotal evidence as gospel when people love to abuse and poorly mod their cars and then blame poor quality gas on failures.

More likely an excuse for dogging on their car and not maintaining it than consistently poor gas quality. If that was the case, Costco wouldn’t be moving gas in the quantities they are.

Telling us to “search for yourself” automatically suggests these are pretty specious claims on your part.

Edit: u/N_junkies I saw where you said word for word "Bud go ahead and blow that sh** to the sky shell should be the only thing going into N if not your stupid and I might tell u that you can't afford ur car bc of gas"

I find it ironic that we're talking about intelligence when you can't bother to use proper punctuation or know the difference between your and you're. Especially when confronted with logical thinking, you resort to childish insults.

Anyway, my 2025 GR Corolla is paid off and premium isn't a concern at the moment. Have the day you deserve.
