The energy in fuel with 10% E is way less. Enough that my X could barely hold 55mph in a headwind. When i switched to 93 octane my power and mileage came back. When i fill up in WI with real gas my X runs like it was supposed to.
The ethanol is 10% less energy per gallon than gas. There is a 10% mix. So, 10% of 10% means there is 1% less energy per gallon.
If the engine is adjusted to compensate, which all in the last 20 years or so are, the power will be the same. You could burn 1% more fuel to do it.
So, if you had been getting 25 mpg with straight gasoline, you could drop to 24.75 mpg. I defy you to be able to tell that.
I have been running it since the 80's in all my engines on the farm, and there are a LOT of them, including small ones. I have not had ONE SINGLE PROBLEM.
Not sure in your numbers either, but i can tell you that i can see the difference in my mileage and can definitely feel it power wise. Ethanol fuel is good for the corn growers and bad for motorists!
