I'm not sure there is any truth to ethanol burning "cleaner", but I believe it does have a much higher octane rating than regular fuel. It also has less energy/volume than regular fuel, that's why you get worse mpg with it.

Some people can get away with 87 octane, but most find the truck runs/performs better and gets slightly better mpg with 89 octane. If you don't hear any knocking, your fine (and you probably have a knock sensor that will retard timing anyway....but this would be the reason for less performance/mpg).
