I only use nonethanol in my boat, UTV, lawnmower, etc. What is the best brand of fuel stabilizer for storage? Thanks

Star Tron in the boat, which generally gets E10 because its hard to find high octane clear out here.

Usually just use a little Seafoam in my stored clear gasoline for small machines.

I don't use one. Keep it away from light and in air tight containers. It works fine after 2+ years. If your container leaks fumes, you will have a problem regardless of what you put in it.

I have been using Startron for over 10 years in my boat, chain saws, and mowers when I put them away for the winter. Have never had any issues with bad gas. Two of the dealers I use for chain saws swear by it.

I use stabil marine 360. It seems to work well. I put that and some TCW3 in my boat once hunting season starts, and come march/April it fires right up.

Y'all know if Startron has a shelf life? I just added a bunch to an old 6 gallon can from last year and realize I opened it about 4 years ago and it's been in the garage ever since.

I use Sta-Bil and it works for motorcycles, but I've never heard of Star Tron. It may be just as good.
The only two times in the last 30 years of owning boats that I had carburetor (1) or injector (1) issues were both when I happened to use Sta-Bil Marine. I've never had an issue when I don't add anything so I won't ever add anything to boat engines ever again. Outboards are just super picky.
