    It lands in the fly-over states, all of which are red. Amazing conundrum for the independent "get the gubmint outta my life" conservative.

    Where's the outrage? (asked with mulligan issued to our NJ friend who dared speak out about this)
    QAnon / GOP Republicans mentally lack the necessary intelligence to even tell a decent lie (Ex: A cabal of Satanic, cannibalistic pedophiles run a global child sex trafficking ring and conspired against former President Dotard dRUMPf during his term in office... Jewish space lasers, etc.). What in the hell makes anyone believe these melon heads can actually govern?

    This is true. Simply put, alcohol contains less energy than dinofuel.

    Yep, I always see an MPG drop with ethanol and also that gas they use in the wintertime. It's about 3-4 MPG here. Fact of life. Good to know about tho' so you don't think there's something wrong with your vehicle.

    Now you know why (in part) food AND gas prices are on the rise.

    It's also not good for any engine but small engines tend to suffer the most.

    Look on YouTube for phase separation experiment and you will see why.

    Gas mileage does increase with non-ethanol gasoline.

    Here is the crazy part, You have to consume more ethanol based gasoline than non-gasoline to go the same distance. Ethanol based gasoline produces more CO2 for the same distance as non-ethanol based gasoline. Ethanol based gasoline releases more CO2 to the environment than non-ethanol gasoline? Where are the AGW alarmists?

    ----
    burning ethanol actually produces 54% more CO2 as global warming pollutant than gasoline due to the fact that ethanol has lower fuel efficiency.

    BUT, and this is a big but, the CO2 from the ethanol part is carbon neutral.

    Octane (n-dodecane): C12H26 + 18.5 O2 → 12 CO2 + 13 H2O 18.5 x energy units

    Ethanol: 2 C6H12O6 + 12 O2 → 12 CO2 + 12 H2O 12.0 x energy units

    Because of the reduced mileage, you have to consume more fuel to go the same distance, which results in more CO2 release.
