Is it only really Top Tier gas if it's labeled?
Just wondering because some places have it labeled at the pump and then I go to some places that are supposed to have top tier but it's not labeled.
Edit: I'm aware of how to find stations with top tier gas. My question is strictly if it's supposed to be top tier but isn't labeled as such can it still be? Because I can go to different stations that both show as top tier but one is labeled at the pump but the other isn't.
