Our new Casey's has several choices now for the gas pumps.
E-10 (Unleaded 87), E-15 (Unleaded 88), Unleaded 87 no ethanol, Premium 91, E-85. And Diesel too
It's best that I fuel our vehicles, my very intelligent (but blonde!) wife just can't get it right.
We've found that E-85 will run fine in an older non flex fuel Ford Taurus, but the O2 sensors don't like it and the check engine light comes on.
She hasn't tried Diesel yet AFAIK
