    I'm wondering what kind of gas mileage you all are getting? I think locally gas prices are starting to even out between the two grades of gas and I would rather run none ethanol gas.

    Yes. When I use E0 I usually see .5 - 1.5 increase in mpg. I was using it regularly, but I’m now running a tune that prefers 91+ octane. I can only get E0 in 88 locally. 88 E0 is the same price as 91 E10 in my town.

    I have a 2017 FFV 5.7. I usually run E0 and have run a few tanks of E10. I haven’t really noticed much of a performance or mileage difference, but I personally prefer no ethanol. The E10 is usually a little cheaper where I’m at, so I pay a bit more for E0.

    I use Maverick Pure E0 87 most of the time. I've gained about .4 mpg in the city and about 0.8 mpg in the highway. My main reason to run Pure is I'm totally against ethanol and don't want it in my tank if at all possible .

    Thanks everyone it seems like prices still will have to get closer in order for it to be worth it. But doing some reading is seems that the manufacturers use E0 to calculate gas mileage.

    Generally, 10% ethanol does not cause any damage or harm to the engine or fuel system unless it sits for a long time. Performance gains are usually insignificant as well. I can buy 87 e0 locally but it is usually more expensive than 93 by at least 10 cents. So at least $20 more during a 30 gallon fill up. I can go another 100+ miles with $20 in 87 e10.
