The point is to reverse phase separation of Gasoline versus Ethanol+Water.
Really only a problem with vehicles that sit a lot, or excessive water infiltration. Just driving around re-mixes phase separated Ethanol+water well enough for most people.
When my pickup truck mostly sat for a couple of years, I was not most people. Any cheap dry gas helped a lot with the problems starting and idling and the occasional cut-out the first few minutes of driving. Using E-Free helped even more. Now I use it more often, and have gone back to E10.
