Where I live there's 3 refineries, shell, Chevron and Tosoro.
the non-branded gas comes from one of these 3 refineries.
You'll never know which one though. If you goto Costco and happen to get a batch of Chevron, great! You'll never know it though, and don't expect techron to be added into it. but definetely some detergency, as mandated by the epa.
Are you guarenteed to get Techron if you goto a chevron gas station? NO. You can't prove it. But we assume it's in there.
Shell is/was doing the nitrogen in their fuels, they made the dealers pay for the nitrogen equipment and pay extra to have it filled. Dunno if they're still doing that or not, but nonetheless, I stay away from shell, I don't like paying more to get less.
But when I goto Costco, I"m assuming, they're buying the cheapest gas from one of the 3 refineries at that given moment of order. my beef is, I'm not a fan of mixing additives.
Personally the gasoline is the same across the board.
it's the addtive package that makes it different.
So I like others have said, add a dose of Redline SI-1 or Seafoam or Gumout (yellow bottle). Usually it's done at the oil change, or halfway before the oil change, which is about 6000 miles.
I don't contribute to chevron's profits directly.
