The main difference is the additives that are injected into the gasoline as it is loaded on the transport before it is delivered to your gas station. Each company has their own proprietary additive that is blended into the gas at the product terminal, not at the refinery. Also, ethanol is blended as it’s loaded on the transport as well, not at the refinery.
Now if you live close by one of these major refineries, it might be that your gas comes straight from that refinery storage tank to your gas station. But, most of you will be getting gasoline that was delivered via a pipeline into a tank with other companies gasoline’s.
Most all the gasoline you buy comes from one of major oil companies, with the major difference the additive pack injected right before it gets loaded on the transport trailer. But, their are still a few independent refiners in the US and many of those still deliver that gasoline to the terminal into the same tank as the major oil companies.
But, with all that I would still recommend that you buy your gas at one of these major top tier stations as the additives injected and quality control of the gas from the refinery to your gas tank is a higher quality from the proprietary additives and the QC that goes into making sure it stored and delivered in a proper manner to your vehicle. The gas you buy at Walmart, etc might be the same gas but not have the additives the major top tier companies use.
Stay way from the ran down no name stations, some buy transmix off spec gasoline, rare but has happened.
in summary, most all the gas you buy is the same with exception of the different additives. Just stick with one of these and you will be fine.
