Maybe a fuelish question?
Just wondering if you get better mileage towing with premium gas that does not have alcohol in it over regular gas with alcohol?

Ethanol gets 20-25% lower mileage than pure gasoline. So if you are burning 85% gas/15% EtOH then you'd get 3-4% less than pure gas. I think that's what the OP was asking.
When I burn E85 I get 20% less miles per gallon then I do on Regular (E15). This was not towing. So that would support the above findings. Ford says that I do get more horsepower on E85. I called the Ford support people and I was told that I would not see any benefit in using a higher octane fule in my low compression 5.4.
