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?

Toyota Echo driving from Houston to Atlanta and back several times, I noticed a drop in mileage from 43 highway to 39 highway. I came to realize it was the alcohol in the gas. In this case, ten percent alcohol reduced mileage by ten percent.

That shows the danger of informal testing. You are saying that you got no energy from that 10% ethanol. Other factors like vehicle loading, driving style and wind might also affect the results.
Not so fast. I've heard of many people claiming a 10% drop. In an engine designed for pure gasoline, the alcohol can trick the computer into an incorrect air/fuel ratio which can waste more than the energy available in the alcohol. Anecdotal? Sure, but enough anecdotes starts to become truth.
