To each his own, kinda like um, oil. I prefer Sea Foam for storage. Never an issue where as I have had with Stabil. Just use what works for you.
Just use both seafoam and stabil, mixture of both for winter storage. That way covered either way right???

Just do not over-do either once on my push lawnmower I put stabil in the gas tank thinking I was done mowing for the season and first time ever having to take it back out 3-4 weeks later to mow one last time I could not get the darn mower started due to overdosage in that small push mower gas tank.
That overdose statement sorta turned on the light bulb!

I had pulled the plugs and cleaned them and truthfully left the gap alone. The first attempt at a start up was NOT met with success. After getting battery back up to full charge before attempting another start I pulled a plug and while cranking observed a nice blue/white arc. Guessin it just took a bit to git what I wuz passing for gasoline into the combustion chambers. But with Phatt Ghurl sittin THAT long unused the very FACT that ALL the mechanicals on her are operating as they should be and I've done ALL the required maintenance speaks well of these Honda Valkyries we ride.

Yesterday I washed and shined her up. Just about done when the young Lady brought my mail. She rides an H/D. BUT she was admiring Phatt Ghurl-sun was out and the reflections off the chrome were-well-Very bright. Asked her to take a guess how old my Ghurl is. She looked again and said-maybe 5 or 6 years old.

Wished I'd have had a camera as the look on her face was priceless when I told her it was comin up on 19 years old!

RIDE SAFE.
