    I think you bring up a good point. In order to get E10 with octane of 87 the 90% gas must have been 84 to 85 octane which is poor gasoline.
    Since most E10 in my area has octane of 89 to 89.5 the base gasoline is hopefully at least 87 octane.
    The other concern I have with using the non-ethanol blend, that costs 10 cents more than E10, it may not be purchased as often, due to the additional cost. This may lead to the gas becoming more stall.
