Ethanol is getting harder to find anymore and is a bit more expensive than Premium fuel
Thoughts?

Ethanol pretty much sucks in anything from a lawnmower on up, it is not "better" in anything except the corn lobby's pocket book.
Besides retaining much more water than alcohol free gas, ethanol has one third less heat output than gas, so it makes both mileage and outright performance suffer as well. The excess water entrained by the ethanol will also help corrosion build up on just about any metal other than stainless steel, so it is not good for the mild steel fuel lines and fuel injector components in your car either.
10%EToH in gas was supposed to extend the available gas supply during times of oil shortages; but as we have been operating in an oil glut for several years, the only rationale for even allowing it in gas is to sell more corn and elevated prices on the backs of uniformed motorists.
