I don't get this, but we have 3 Kwik Stars here (same as Kwik Trip), and the 2 non-truck stops have 87,89,93..... the truck stop has 87.5/89.5/93.5. Wouldn't they all get the same gas, being the same station?
I know some places don't get the same gas, I worked at Hyvee Gas a while ago, and we got gas from a distributer that provided us with random types of gas, one day we'd get Amoco, the next day Exxon (we don't even have any Exxons here), next day Phillips 66, etc. Another question would be: I've heard to stick with one brand of gas for best results, wouldn't getting gas at a place like that not be good?
