Kum N Go has been adding E85 to all their new or remodeled stores in the Tulsa area for the last year and a half. That's the only place you'll find it here. They're an Iowa company so they are more invested in Ethanol than QuikTrip, Conoco/Phillips or the other local outlets. There are 3 Kum n Go's within 2 miles of my house and 2 of them are the new model stores with E85, so it's convenient for me or I would use regular unleaded like when I'm out of town.
Real gas has been a premium around here for the last 10 years. No clue why other than some of the small independents have used it as a selling point and they have no competition in the areas where their at, so they jack it up.
