A buddy of mine drained his pontoon fuel tank last season after not using it much in 4 years. When he drained it there was a substance that looked like saw dust in the fuel when left to dry. I'm assuming this is the old ethanol.
Anyway, he uses non ethanol fuel now and stabilizer with no issues.
I use ethanol fuel in everything but most of my power equipment is used constantly so I've had no issues. I start my Snowblower and let it run a few times during the summer.
