Cenex in our area, E0 and E10 are both available, and now Cenex is TT, so all gasoline they sell is TT. Did a recent check of stations in a town west of me. 11 stations and all but 4 offer E0 year round. Top Tier has nothing to do with ethanol, it is a detergency standard. Either way, I don't spend a lot of time worrying if the gas I am using is TT or not.
