You can get 100% gasoline top tiers, they're just hard to find. Thankfully I live near a gas station that's not certified because they're too small, but after looking into their additives and volume/gallon they're essentially top tier. They use the same additive as Chevron. (acme fuel/fast fuel in Olympia, WA).
It's the ethanol. The nice thing about ethanol is that it seriously cuts deposits by itself as long as it's fresh. Top tiers are still required to maintain a certain volume of detergents, though. Managing deposits is only part of the certification.
And I did confirm that Arco is now a top-tier. I had no idea, I never would have trusted them before. I'll still hit up the Costco over them any day though.
