You're saying mixing has no effect.
Really?
Perhaps you need to pay closer attention.

I here what your saying. I only tested the two fuels back to back one time. So it was not enough data to truly come to a scientific conclusion.
But trust me I'm very careful when refilling to get the same amount per tank.
(I use the same level spot at the same fuel-station, I check the fuel level with a measuring rod, I take notes on the ambient temperatures to account for the coefficient of volume expansion for gasoline being 950x10-6, I test the alcohol % of the fuel)etc.
I thought for sure I would see somewhat a gain when running the
non-ethanol fuel. But after seeing none I decided it wasn't worth it at this point and time in tuning my car for maximum FE. So now I have been doing all my test with the 10% blend.
