As to the fuels, I was told that there are only a handful of suppliers in this part of the country and the fuel all comes to their tank farms. Then the various other "brands" pick up the fuel and add their own additives/additive levels to that same fuel. So it'* partly the additive packages.
I do know there'* a tank farm 30 or so miles from here along a main highway for a brand of fuel with their name all over it. Then across the side road there'* another tank farm with no name on the tanks. I haven't sat and watched but I suspect they are the same fuel stock out of the pipelines, and the other branded or noname trucks pick up at the side farm while the main brand for the company picks up at the one with the national label all over it.
Then in this area everything is 10% ethanol. I keep getting a sense from some posts that a few stations have fuel that'* not 10% ethanol, implying it'* 0% or less than 10%.
I do know that area Shell stations offer an additional 5 cents off the V-power. I mixed it with the regular that was in and used only premium for a while. When the steps are 10 cents and 12 cents, the 5 off makes it much better to buy premium and occasionally regular than to buy the mix of the two called Plus, which may not be 50/50.
