You make a good point about Costco gas. The comment about higher volume sales makes perfect sense. I guess the better question is: How much sales volume does your fill station of choice actually see? I suppose that even a Shell station in the middle of BFE that only gets a few vehicles a day could be prone to moisture issues. You are also correct on the refinieries - 1 big fuel depot will provide gas for several different brands. But like we both mentioned, the difference is in the cleansers that are added. I've done a little research on the nitrogen cleansers that Shell uses and I like that brand. Just a personal thing, YMMV (quite literally in this case, lol).I like the Shell gas too, but I believe you are mistaken on Costco gas. It is usually always the lowest priced premium grade around, due to the fact we are getting wholesale pricing. Plus, the best thing about Costco gas is the fuel is fresh. So much volume goes through the pumps at the stores, there's no time for fuel to sit in the storage tanks and collect condensation.
Also, I am trying to find the 60 mins story I recently watched on TV. They interviewed a guy at the refinery where the tank trucks filled up. He said all fuel from Exxon, Shell, Race track, etc... all filled their trucks from the same spout. There is virtually no difference in the gas makeup. The only thing that changes is someone like Shell will add a detergent pkg to the tank after fill up. The marketing behind Shell and the Exxons is unbelievably misleading to the public.
If I can find the story from 60 mins, I will post it up.
This is some good advice. I need to take advantage and get a shell card, I just haven't yet (other issues to deal with first).
