Almost every station I go to has ethanol (up to 10%) added to gas. For a long time I had the option in my area to buy non ethanol gas but now it’s harder to find.
If a gallon of ethanol gets less mileage per volume than gasoline, then how is it better for the environment if I have to fill that much sooner on gas because the ethanol component lowers my tank range?
In: 101
The 10% ethanol fuel content is negligible on gas mileage but does slightly cut back on emissions, plus slightly reduces reliance on foreign oil doing so.
I think marathon’s do still offer a 4th option which is 100% gas but at the middle grade level from what I’ve seen. So 91 octane (we typically have 87, 89, and 92 or 93 depending on which company). We don’t have any close to us but I see them in Indiana or Michigan when driving through.
