Now that's the famous million dollar question.
We Europeans got away with it since in 2008 Germany said
nein to ethanol fuel and the rest of the Continent caught their drift.
At the time I investigated what could be done to counter the effects of ethanol in fuel.
You quoted fuel additives. The only help you'll get is from combustion enhancing additives. Plainly put they will help your engine run moisture-soaked ethanol fuel (ethanol "helps" your fuel retain water... too tired to give the details right now

). I have no idea which brands market these products in the US (STP?). :banghead
Some mechanics suggested fitting a 10 micron filter to the fuel line. While it may work to help keep water out of the injectors it will need to be regularly cleaned or you may end up stranded in the middle of nowhere (these filters clog
fast).
By attracting more moisture you also end up degrading the "good" part of your fuel faster. The only cure is to avoid having fuel sitting around in your tank for too long.
I won't spend time lecturing you on "how ethanol dissolves gum etc" because frankly that piece has already been played
ad nauseam on the Internet.
In short: there's no "magic bullet" to cure problems caused by ethanol blend fuel. The best solution: avoid it when possible.
