Been that way for decades that it is all the same spec for the grade pumped except the additives.
I've been to a closed refinery which supplied directly to stations. It had specific tanks for additives for that brand. None of those brands had any refineries near this one.
Murphy is at Walmart/Sam's Club because Charlie Murphy bankrolled Sam Walton to expand from his first store. Murphy sold it's last refinery a several years ago.
In the early 1990's while dismantling and liquidating a Shell refinery in SoCal, the Shell guys told us to by regular unleaded in August because it was actually Shell premium they had too much in tank farms which they needed to get rid of before due seasonal regs by CA.
Amoco white gas had a higher RON ("octane") rating than all others at the pump. It cost more too back in the day. Amoco tore down a shitton of refineries it owned in the 1980's across the USA. It was pure reformate from naphtha reformers, if memory serves me correctly, the same thing that propellor planes used in WWII for high performance.

The gas itself is the same.
I hauled gasoline for 5 years until a bad accident took me out of it.
The truck fills at a refinery. Locally there are a few, shell near the airport, marathon in garyville and 2 in Chalmette. We loaded fuel for all brands at all of them. Meaning we could get chevron, shell, "off brand" at any of them.
The base gasoline is the same but when we select the account we are loading for it let's the system know what additives to add to the gasoline.
The additives are injected into the gasoline while loading.
Same with dyed off road diesel fuel vs highway diesel fuel. It's the same exact diesel, if we selected off road diesel fuel, it will add a specific amount of red dye into the diesel as it loads.

The #1 reason name brand stations add stuff to their gas is to be able to check that their stores are actually selling their products and not from another (cheaper) supplier. Sure some of them think their additives are better than others but that isn't their motivation.

I drive a lot of hwy miles
Cheap gas at Buccees and race track ect averages 2 mpg less for me

I've noticed this myself. We have a Shell gas station, walmart and a few cheap no name places.
The Shell is always mire expensive but I definitely notice a few mpg better when I use it as compared to the cheaper.
The additives definitely make a difference.

The same gas that is put in the tanks a Shell are put into the tanks at Wal Mart.

There are maybe 1-2 other additives with the same active ingredient, but I forget who makes them.
Detergent additives are the same...you can drink the Kool Aid if it makes you feel better, but Techron MIGHT be marginally better than whatever XOM is putting in vs whatever Valero is putting in.

This is also bullshite. The interface, or transmix, if any gets cut out and sold on it's own as just that, transmix.
That gallon of gasoline you think is "Chevron" was sitting in the same tank at a truck rack that also had customers with allocation to pull XOM, or BP, or Bucees, or fill in the blank mom and pop wholesaler.
I've got 15 years in the industry...buy whatever is cheapest from whatever station is the busiest.

I've been putting the cheapest gas I can find in my vehicles since 1990 and never had any problems other than my first car throwing a rod at 375000 miles because my ex ran it low on oil.

Bunch of sheep in here who can't think for themselves. It's astonishing how well marketing works on the majority of people.

I know with some Toyota engines. It has more hp and better mpg with 92 over 87. The Tacoma even says it in the manual. Generally higher octane is only necessary with high compression engines. But most cars can adjust timing based on octane. Still if you have a super charger or turbo 93 is better best yet is to run e85 if possible. Some cars you need to modify things to take pure e85.
I thought you were more of an appliance guy. In my younger days, we did race motors around BTR. Jims Wheel Alignment's, "Delta Lady", John Prevost, "Shazam," to name a few. Also did a little motorcycle work, back when Mike Gerald was racing. Got family still involved in it.

You see a lot more requirements for higher octane due to higher compression and lower displacement.
In addition, every manufacturer is trying to run as lean as possible to lower emissions.
Lastly, everybody is using thinner and thinner engine oils ( even 0wt) due to super-close internal manufacturing tolerances.
All of those factors contribute to a requirement for higher-octane fuel, as well as the higher performance factor.

Love the boomers here stuck with 40 year old thoughts and logic. Just go to any reputable gas station and you’ll be fine (if not in an exotic performance vehicle)

I am not I've also never been to a mechanic and only buy used cars so I've gotten good at fixing them. I've done transmissions and engine overhauls as well. I just can't do alignments, body work and tire changes. And machine work..

Alignments, Jim's in BTR. Know the family. Jim, who passed, Mike and Rob, he's the son that had the boat 5 liter, Delta Lady.
Sounds like you've done a lot like me.

I went to a Marathon refinery years ago for training (I was from the E&P part of the company before they split.). At the terminal there were trucks from every company. After getting the gasoline, they went over to the place where the "magic" and proprietary additives were injected. So I'd say no, it's the same stuff.

I use whatever Kroger sells bc that’s where i get fuel points. Seems fine.
