I'm pretty sure that my Speedway 93 Octane has 10% Ethanol.  No problem.

costco's sell gas down there? i always wonder where these companys get there gas.

Most like Costco and other non-branded stations buy off the spot market.No additive package of course, just gasoline to a minimum octane spec.
