Off season fuel conditioner

What do you add to the tank for the winter?
Why did you pick that one?

Getting ready to top off the tanks for the season end.

I always used a "stabilizer" called Sta-bil. Can't say why I used it. At the same time, I always took mfr claims with a couple of grains of salt. But I didn't want to chance a bad outcome and it was relatively cheap stuff. I never saw any objective article reporting on independent tests of stabilizer concoctions. I think fuel additives are somewhat over-hyped.

Others on the forum may be able to point to good reasons for one brand over another... or any brand for that matter

UPDATE: Got un-lazy and thanks to Google found this citation on testing: https://www.boatingmag.com/gear/boating ... ers#page-3

ANOTHER UPDATE: make sure some of the stabilized fuel is in t he carbs before hibernation - that is, run some thru the engine before you winterize.

I've also used Startron. Not sure if it's any better (or worse). The main thing is to fill the tank(s) full as possible with conditioner, then run the motors a bit to get it into the fuel system.

Here's a piece of good news on this hotly debated subject: This summer was such a mess--way too hot, then raining like crazy, then... repeat. I filed the tank of my 19 footer last November with that 10 % ethanol crap, stabilized the fuel, and burnt only half of it this entire year. Still, the motor ran just fine. I intend to pump the rest out before refilling with fresh gas and more stabilizer, but that really old gas DID run fine.
