Shell is TT. All octanes included. Don’t go chasing waterfalls, please stick to the rivers and streams that your used to.
Shell stations have stickers on their pumps and all grades are top tierSo any and all grades are top tier if the company is top tier? If I go to shell, all of their fuels are top tier?
Generally the local station does not add the additive package. To my knowledge only Costco adds an additive package on-site. I can only assume it is to cut costs, they get just the plain non-additive product from the refinery/tank farm, & do it themselves.
The fact that you've seen "the same truck" delivering to different brands means nothing. Oil companies do not run their own trucks, they are contractors.
it's a mix of Marketing, and additives... in my area, all the fuel sold comes out of the refinery here in town...the oft repeated statistic is they produce 25% of the gas sold in the state of Ohio...
everyone in the area gets the same gas... just with different additives blended in...
I work at a Meijer Store, and in the past, filled in at the Gas station a lot....there were a couple years I was at the station more than i was back in my regular job....
I was there when we "became" Top Tier... we didn't change vendors for our fuel, they just changed the add pack the put in at the rack...
Meijer Decided that it was worth the Money to Join the Top Tier program, pay the licensing fees, and for the specific additive formula.
we knew the switch was coming, we were "going Top Tier" on a certain day... they didn't come in overnight and drain the tanks, and refill them with better fuel, they started a filling our tanks with TT Fuel a few days to a week before... then a couple weeks after the day we "went live" reps from TT came out, and applied the decals on our dispensers and some in store signage as to why Top Tier is better, with pictures of a dirty valve and a clean valve...
all that to say, all Top Tier is, is some Marketing to give your Customers a warm and fuzzy feeling, coupled with a specific High Detergent additive package that they mix with the local bulk Fuel...
A close look at the door on the tractor shows a contractor. That truck is not owned or operated by Chevron. You live in the Bay Area, the big Coke bottler in Benicia switched all their deliveries to Reyes, you see it clearly on the trucks. Same trucks, same Coke logo, but run (owned?) by Reyes. Coke is not liable for any driving incidents. FedEx home delivery same. Look at the ghost writing behind the door on FedEx home delivery vehicles, there's a contractor's name. I worked for ABF Freight & we brought some of the Pepsi trailers out here for delivery, but we were allowed to use them during transport. One of our drivers had that trailer & was dispatched to Coke in San Leandro...... OMG, fit hit the shan, someone called & said don't you EVER send a Pepsi trailer in here again!! LOL. Another freight company I worked for had trailers advertising other products, See's Candy & Good Guys. I'd drive up with a See's trailer & all the office girls wanted to know who was getting candy.... LOL. My point is the writing on the outside of the truck doesn't necessarily match what's inside the truck.Some oil companies do have their own trucks and tankers, or at least they used to. I see fewer but many had their own fleets at one time.
I can understand it has to meet minimum EPA, so Costco just has to add the package to elevate it to Top Tier. I'm thinking they have two tanks for either grade, so 4 total, & can switch between tanks. With the volume of gas they pump they almost have to do that. They don't sell "midgrade" as it's just 50/50 regular & premium. Next time you (or I) are in there we should look how many fill covers they have, lolI was under the impression that Costco gets non-additive fuel delivered, but I found that federal regulations require at least the "lowest additive concentration" of an EPA-certified detergent additive be in the tank once it's done being filled at the fuel depot. So what Costco adds is on top of what's required to be in the tanker heading for the Costco gas station. And the other thing I worry about with Costco is how well it's mixed when there's a delivery going on and customers are actively pumping gas coming from the same tanks that are being filled with the metered additive being added. It's probably not that big a deal, but I'm thinking it's probably not perfect. It would be perfectly blended (within a few minutes) if they shut down a tank or waited until they closed for any deliveries.
Mixing properly blended fuel in a tanker with properly blended fuel in the underground tank should result in the correct concentration of additive regardless of how well it's blended. But Costco has that variable of mixing in additive while it's being delivered and while customers are pumping.

A similar explanation can be applied to "Dexos" approved motor oils, and other certifications. Lots of excellent oils would pass the rigorous Dexos testing process, but someone decided it wasn't worth the cost to have the Dexos label on the product.Top Tier is to fuel what "certified Kosher" is to food. Just because there is no certification does not mean that the product is inferior. All it means is the marketer did not want to pay the licensing fee. Citgo and Sunoco are now on the list. They weren't always. BP and Irving used to be on the list. They are not now.
Does that mean bad gas got better, or good gas is now bad? I doubt it. I think it means that somebody made a marketing decision that it was worthwhile to pay the licensing fee, or that it was no longer worthwhile to pay the licensing fee.
