I’m wondering about places like Chevron, ARCO, etc., as opposed to the little “Space Age” or “Comet” or other gas stations in my neighborhood. Lately the big chains are a solid fifty cents more per gallon.

National brands have specific, proprietary formulations, especially for their higher grades, which include additional cleansers , lubricants, and filtering. Running these consistently may offer some benefits to engine part longevity. The local stations buy gas on the open market, which could be the same base gas that the others are buying, or leftovers from the others. It’ll all run your car just fine, though.
