I use Startron in 3 boats, 1 snowblower, 1 bike, 5 cars, 1 pressure washer and 2 lawnmowers (no fibreglas tanks) with zero problems even if it sits for a year. I used Stabil in the past (red, before E10) and had problems.

Just a second thought. If you buy Startron look carefully at the bottle. There is one small bottle that will treat 128 gallons and another that looks the same but will only treat a small percentage of that. Obviously the 128 gallon treatment bottle is much more expensive.
