I don't know if they have any on the west side but nearly all the Maverik gas stations around here have Ethanol Free/Pure Gas. Some of the CENEX have it too. My truck doesn't hardly get driven much, less than 5K in 2+yrs, so I generally fill it up with Ethanol Free. That's all I use in my 4wheeler, snowblower, lawn mowers, and keep in gas cans.
