Seafoam will work as a stabilizer too. In my personal opinion, it's the best, but I'm sure there are arguments for and against. I've had great luck with Seafoam in practically all my internal combustion engines for years. My motorhome probably sits the longest between fillups, and so far it cranks and runs like a sewing machine. In fact, I was able to make the genset run (it was clogged up with old fuel varnish) without replacing the carb when I first got the coach by soaking the bowl and float and running raw Seafoam through it. Now, it runs like a charm and I keep 1oz/gallon of gasoline in every fillup.
