The TT website only states, unless I missed something, that the TT logo be "prominently" displayed. Now we can discuss/debate what does or doesn't meet the definition of "prominently displayed" but my guess is a 3x3in sticker slapped anywhere will be in compliance with the requirement. Fwiw, TT also states enrolled brands/service stations are subject to unannounced inspection for compliance. (why a station wouldn't display the TT logo more prominently like you see on that 76 signage is beyond me. It's def a selling point for a lot of people like myself)

Yes, the addtl detergents do a better job of helping keep clean the entire fuel system including your injectors, piston tops and combustion chamber.

The EPA mandated level is the bare minimum. AAA did a long term study and found significant benefits of using top tier detergent levels. Plus, in order to market your gas as TT, TT requires certain chemicals known to be problematic (like MMT) not be present in the fuel.
