Ethanol-Free Gas

At our first visit to the new Buc-ee's in Huber Heights, I noticed they sell ethanol-free gasoline.  I didn't even know it was a thing, so I went digging into it.  Most U.S. gas is blended with ten percent ethanol (i.e., E10), and ethanol absorbs water and can be corrosive.  That can lead to fuel system corrosion, “gumming” or varnish buildup, and hard starts after sitting a while.  

Ethanol-free gas is preferred because it’s more stable and causes fewer maintenance issues, and is used in boats, lawn equipment, motorcycles, and classic cars.  I can buy ethanol-free gas at our local Marathon station, and I'll start using it in my lawn mower, trimmer, and blower.
