The pump will usually say the max ethanol content, but ad you said, who knows what’s in the ground or the tank. That being said, I have an ethanol gauge I watch like a hawk because many of my race cars were not flex fuel and tuned for a specific alcohol content. Kum and go has been very consistently e70 for their ethanol blend, and e10-e11 for their gasoline. I’d imagine QT and Costco are similar due to the amount of traffic they have and how rare fuel sits in their tanks.</p></blockquote><p></p>
