I'll double check, but I know the 93 isn't E85, and I pretty sure the 97 isn't either. I was able to get it at a Sunoco a while back and the 105 (maybe it's 101) is at BP and it's sold as a performance gas. I'm pretty sure that one isn't ethanol either. I'll double check both places this week though and make sure my story is straight.
