The EPA has currently suspended enforcement and recordkeeping requirements on detergents anyway, "to avoid the disruption to the fuel distribution system."
Such giants as BP & Exxon-Mobil aren't even on the list of top-tier retailers, while "Turkey Hill Minit Market" & "Road Ranger" are! What a crock!!

I seem to recall something about a similar suspension, but wasn't that back when Hurricane Katrina smashed up a bunch of oil production facilities near the Gulf of Mexico? I thought the suspension was temporary and meant only to minimize disruption. I don't recall any permanent suspension, but such things are often not widely reported.
Anyone have any citable facts?
As for top-tier gas, there may be several reasons why a brand might not be listed: perhaps BP and ExxonMobil use only the required detergents in regular gas, but have more additives in the premium grades? (I have no idea if this is true, I'm just speculating.) Such a condition would violate the top-tier requirements.
Perhaps getting top-tier certified requires the payment of a sum of cash that they simply don't want to bother paying?
Who knows who supplies the Turkey Hill and Road Ranger stations? Maybe they get their fuel from a refinery that puts top-tier qualified additive levels in all their grades of fuel?
