Up until 4 or 5 years ago, we used to be able to buy 85 Octane gas here in NY state at the Oneida nation gas stations.

You are the most reasonable of E10 defenders. I see your other posts readily acknowledge the "ethanol in gasoline industry" lobby that artificially raises the cost difference between E10 & E0. As for me, I love to tell the efficiency difference between E10 & E0 is MORE than the btu difference content(3% less for E10, compared to E0). Gasoline engine engineers designed 87 octane gasoline engines to work best using 87 octane ethanol-free gasoline(E0), which IS 87 octane. E10 however, is a blend of 114 octane component AND 84 octane gasoline component. None of the components are 87 octane. That is why my last five 87 octane low compression ratio cars, over decades of records, have 87 octane E0 MPG improvements over 87 octane ethanol blends (E10) of 8%, 8%, 7%-8%, 7%, & 5%. Those percentage differences occur with me, a featherfooter with no desire to get any performance, other than good MPG, whether with E0 or E10.
The successful "ethanol in gasoline industry" propaganda campaign, that 87 octane E10 can be labeled as 87 octane is a lie.
