I'm sorry I offended you Brandon. That was not my intention. I already apologized in my prior post and again in this post. Maybe we had a miscommunication. I don't know. What you're doing is working for you. That's good. Please have a nice day. I mean that sincerely.
I got home last night from a 7-day, almost 4,000 mile road trip, stopping at Shell, Mobil, Valero, and other places on the Top Tier list of stations. Paying close attention at each station, only one Shell station had the Top Tier logo on their pump. Every single pump I used on this trip did NOT have the Top Tier logo. This trip was round trip from Texas to Connecticut.
I took some Amsoil Upper Cylinder Lubricant along with me, so used it about every other fill-up... whether it needed it or not.

Just for fun....No Kroger or Fred's in my area.
We do have an Albertsons about 40 min away 1 way. Not hardly worth driving to it. Plus their prices are much higher than other places closer to home.
We are cutting up our credit cards ASAP!
Costco is about 30 min away 1 way. Every time I go there the gas line is all the way through the parking lot. Plus here Costco is not the cheapest gas. I can buy cheaper gas much closer to home.
I don't think it matters if the actual gas station has the logo on there. As I understand it, if the brand, e.g. Shell, Costco, or Marathon pay for top tier , each station of that brand is Top Tier (as are all the octane varieties available).
I dont think it matters in CA.

Shell gas already has upper cylinder lubricant in it. Lake Speed Jr tested it for wear comparison vs non TT gas using UOA comparisons. His test showed Shell is very effective at reducing upper cylinder and rings wear.
I don't know if other brands of TT gas have this property or not.

Any brand of TT gas will be good enough. If no TT gas is locally available, then add a bottle of good fuel additive at least every 3rd tank, IMO. I'd buy bottles of Shell, Chevron, U76 or any brand of TT fuel additive bottle because TT fuel companies know how to make (or buy) effective fuel additives.
Other brands of fuel additive bottles might be good or might be snake oil. For example, I suspect Lucas fuel additive might not clean injectors effectively.
That's an absolute requirement for the license. The one time I recall where it was almost immediate was with Costco. At the time, they used the "Clean Power" brand name but not all Costco gas stations had that system set up. Once it was installed at every single Costco gas station in the US, the Top Tier signs went up. I think that's also when they adopted the "Kirkland Signature Gasoline" brand name. By all accounts, nothing really changed with the stations that already had the dispensing system set up, but they were allowed to market it as Top Tier once they could guarantee that every Costco gas station was meeting the standard.
There are probably some oddball ones. Arco is a Top Tier licensed brand name, but it's operations are by different companies by region. BP sold the brand to Tesoro, which was renamed Andeover, and then was purchased by Marathon. But almost immediately BP licensed back the Arco brand for specific regions (Northern California, Oregon, and Washington). I suppose BP and Marathon could have different additives, but both can submit the additive test results for each one. And as far as I know, one brand could theoretically submit different test results where they have the option to use different additives as long as each one meets the requirement.
No. Injector deposits are still an issue. My understanding is that it's generally a matter of the varnish inherently present in gasoline, where it eventually has to shut down. The gasoline evaporates leaving varnish behind. Then the varnish oxidizes and hardens. The other thing is whether or not the detergents can clean off the DI injectors. I heard DI injectors can be even worse because the heat inside the combustion chamber bakes in the deposits.
There are various photos of gasoline direct injection deposits.
