NON-ETHNOL GAS

[Tkelter]

My manual says 87 octane or higher. I live in Kansas and Hyvee has 91 octane, no ethanol. Just filled up with it today. Haven't gone far enough to tell. I'll let you know if I notice a difference.

My understanding is that ethanol left in your vehicle for prolonged periods will start to eat away at the seals. Is this true? If so, what would be difference between leaving it for long periods of time and constantly refilling it with ethanol based products?

I don't know if its ethanol related or not but as soon as I got released from California gas and put Arizona, Utah, and Colorado fuel in, my MPG shot up 5 miles while towing a trailer.:bowdown:

Brian, I think it had more to do with the altitude than the gas. I had a passenger which I never had before and was towing my trailer and I got better gas mileage than I ever have. Also with the route we took I was at lower speed 65 - 70 than I would be on an expressway so that helped also.

Ehanol is hygroscopic, if it sits it attracts water. Once water is added, microbes can grow, and the addition of the microbes adds to the corrosive nature of the ethanol.
