^^Thx, Bryan. Just Posting it up for any of the 3 Oklahoma Xs would know if they are interested lol.

The Kum and Go's have started carrying E-85 theres one in Owaso and in Broken Arrow that i have seen myself hopefully more to come! I'm ready for a tune

The Kum n Go on the turnpike west of Hallett has corn gas too :)

If they would show signs of adding more places I'd convert in a second. I haven't read or seen anything about it though.

I emailed someone at Kum n Go a while back thanking them for supporting E85. It's hard to add it to an existing station (new tank) so there has to be a market for it.

You can email communications@kumandgo.com to let them know where you live and what you want :)

Kumandgo has an agreement from what I understand with 7/11 that they will not open stores in OKC. That's why Tulsa has more places.
