I was told to repost this since we never talked about gas before. Anyone following the Top Tier Plus standards mandated by the beginning of 2027? It is specifically for GDI (Gas Direct Injection), like we have. There's some that are already compliant. Everyone gets their gas from the same place, but it's the additives that are added for each brand. So, there IS a difference. There are shady places that use lower octane that's mislabeled 93, but it sounds like name brands ones do not.
