the real gas make better mileage?

[OpenBook]

The other day, I messed up at the gas station. I accidentally put in the gas without any ethanol into my hybrid truck (we call it the real gas here)

I only realized 'cause it cost about 50 cents more a gallon than the usual gas ethanol.
It wasn't the super fancy gas, just regular without the ethanol.
I was a little annoyed about paying more and didn't think much of it.

But then, I kept seeing that my gas mileage was way better, like at least 5 miles per gallon better than usual!
Then it clicked! maybe it's that ethanol free gas doing it! I've tried the pricier, higher-octane gas before, but it still had ethanol and didn't change my mileage at all compared to the cheap stuff with ethanol.

Tell me guys, is my theory true?

Your theory could hold up, ethanol-free gas has a higher energy content, which might explain the better mileage, it can be pricier but it can give you better efficiency in the long run

Yeah, ethanol has less energy per gallon than pure gas, so going ethanol free can definitely bump up mileage. Might not be worth the extra cost for everyone though, but the numbers don't lie if you're seeing that kind of gain.

I agree with the others, it'sotally true. Ethanol lowers the energy density of fuel. So, even if the octane is the same, an ethanol free blend will usually get you better mileage. Nice job finding that out by accident!
