there's no "real gas" available locally, so I can't worry about it. When I lived in the Pac. NW, there were a couple of places in the small town that carried it. I tried it in my V8 pickup, it didn't make it run any better and I couldn't see any better gas mileage.
Our gas in Tucson all comes from the same terminal. Only difference is the additive package. So I use one of the more budget gases, Fry's/Kroger, and I buy Techron by the quart or half gallon when I can find it.
