I've joined the 90 octane, non ethanol, with stabil added when purchased gang.
My 4-stroke small engines include 2 atvs, lawn tractor, push mower, snowblower, 1850W portable generator, 2000W portable generator and a 13.5KW standby generator. Picked up a bunch of 5 gal gas cans (that I numbered!), and use them in order filled in whatever internal combustion beast needs it. The gas doesn't get too old.
The smallest generator and push mower are older, and used to use any old regular gas in them, so those got a couple tanks of premium with Seafoam to clean them out when I went to ethanol-free.
2-strokes are a couple of trimmers and two stihl chainsaws. Trimmers get the premix 50-1 fuel or my chainsaw fuel. Chainsaws get good gas with stihl oil. No stabil, but might add it to the regimen.
And so far everything starts and runs when needed.
STIHL ultra HP 2-stroke oil has stabilizer in it.
