    Ethanol and fuels like E85. 1.5 gallons of ethanol has the same energy content as 1.0 gallon ofgasoline. A flex-fuel vehicle will experience about 76% of the fuel mileage MPG when using E85 (85% ethanol) products as compared to 100% gasoline. ... Pure ethanol provides 2/3 of the heat value available in pure gasoline.

    The article linked below is a good read. Worth looking at.
    Under the link I copied and pasted the final results of the article incase anyone doesn't want to read the entire article.

    https://www.edmunds.com/fuel-economy/e85-vs-gasoline-comparison-test.html

    Gas Result:
    From San Diego to Las Vegas and back, we used 36.5 gallons of regular gasoline and achieved an average fuel economy of 18.3 mpg.

    Gas Cost:
    We spent $124.66 for gasoline for the trip. The average pump price was $3.42 per gallon.

    E85 Result:
    From San Diego to Las Vegas and back we used 50 gallons of E85 and achieved an average fuel economy of 13.5 mpg.

    E85 Cost:
    We spent $154.29 on ethanol for the trip. The average pump price was $3.09 per gallon.


    By relating our observed fuel economy to CO2 emission figures found in the EPA's Green Vehicle Guide, we determined that
    our gasoline round trip produced 706.5 pounds of carbon dioxide.

    On ethanol, the CO2 emissions came to 703.1 pounds.
    The difference came out in E85's favor, but only by a scant 0.5 percent

    I can attest to that from a drag racing standpoint. Cars that use methanol (not ethanol but closely related) used roughly 3x the fuel that a car running C12 race fuel would run. Obviously, there are a lot of variables in that but that’s kinda the general rule of thumb. If you have a 347, for instance, and you change it over from gas to methanol, you’ll burn roughly 3x as much fuel making a pass.

    That’s interesting that the article has the emissions stuff in it. I had wondered about the emissions of ethanol vs gas. All the hype that you hear is gallon vs gallon but you never hear about real-world tank for tank or mileage based comparisons.
