I often go to one of a couple Exxon stations in our county that offer 90 octane recreational vehicle fuel. It is labeled 100% gas with no Ethanol added. I see very good fuel mileage improvements. On the level of 3-4mpg better. Even in my old 2007 Edge, I saw on average a 3-4mpg improvement.

This is combined driving.

Ethanol= more fuel consumption. Just the nature of the beast.
