The majority of great dealers that I know of, in areas where E10 has been widespread for years, switched to Startron and stayed with it. This morning was the first batch of E10 that my boat has had in it. My marina has (or used to have), Valvtech-treated non ethanol gas. They may have had to switch as well. The problem I have is that I suspect they just start filling their storage tanks with E10, without having cleaned them out fist. It's a fairly extensive cleanout, and I suspect none do it.
Most of the problems I've heard of have been with two-cycle engines, weed whackers, lawnmowers and the like. Boaters that have problems typically have older boats, and their gas tanks have some crud in them. E10 is a very effective solvent in these conditions. It will clean out you tank over time, and throw that crap towards your engine. Sometimes, particularly with outboards, this is a very nasty process.
I know my vehicles have all seen a drop in gas mileage since the E10 introduction here, and more notable on hilly highways. We have one station left that sell NO E10 gas, and every test I've done has had the same result.
