Based on using E10, I doubt anyone could detect the difference in tank-to-tank fill-ups.

I'm with Daox on this: outside of a laboratory, I doubt you would tell the difference on E10.

But if his Jeep is an E85 ("flex-fuel") capable vehicle, and he's comparing E85 to straight gas, then you would see a difference.

The Aveo isn't flex-fuel.

Every car I have owned gets 2 - 7 more miles per gallon with ethanol free gasoline!
Ethanol will gum more than regular 100% gas also(easier on your engine and gas tank in general)

Most gas stations offer 100% gas AT HIGHER octane than ETHANOL 10% gas so the octane is ACTUALLY BETTER than ethanol! So overall you get what you pay for! 100% (gas = gooder)
