Think about it. Let's say you filled up at a, "Top Tier" gas station, and 30 miles down the road your car takes a dump. And after the mechanic towed it in and fixed it, he told you your tank was full of garbage gas. What can you actually do about it? It's an all but unenforceable, "guarantee". You would be extremely lucky to get your money back on the gas. And that would only happen if you had a receipt, (and who even gets, let alone keeps those every time they fill up?), along with a big argument with the manager.
Unless you have some way to check what's in their tanks, along with where it's coming from, (which you don't), you have absolutely no way of knowing what you are pumping into your vehicle. Let alone it's "quality". I think what's far more important is the age of the station, along with it's tanks. And how much volume of fuel they sell. Stick with newer stations that pump a high volume of fuel. I think you have a much better chance of getting good fuel that way. Rather than by looking for some nebulous sign or emblem that gives you a totally unenforceable, pie in the sky, "guarantee".
While none of what I just mentioned is a guarantee either, it can't help but improve your odds. It's a bit like how people always used to look for those little "AAA" oval signs when they were looking for a motel when they were traveling. It was supposed to more or less help assure, that if the joint was, "AAA Approved", it was a better, cleaner place. The fact is, (or rather was), it had little effect in guaranteeing you a nice room. Roaches don't read signs. More often than not, all it "guaranteed" was a slightly higher price. I put this whole "Top Tier" thing into much the same category.
Is it better to have it than not? Perhaps, but I wouldn't live or die by it. It's more of an excuse to charge a couple of cents more a gallon, and get away with it if someone questions the price.... "Oh, but our gas is, "Top Tier!"
