What Fuel Stabilizer Works Best?

[TLH101]

OK, I have not need to winterize, due to year round use, but now, since I have moved further north, I will have a few months of non use. I need to winterize 1 Di, and at least 3 carbureted machines. I have access to ethanol free fuel at least.
What is the best fuel stabilizer, and best way to use it?

I've been using Sta-bil for years and a while back they came out with Sta-bil marine which I switched to in my skis and boat. Never had any problems. You should really put it in every tank full.

I have been using Sta-bil in all of my off season fuel tanks for years. What is the difference with marine Sta-bil?

Use the Marine Blue Sta-bil. Made for marine applications.

Use the Marine Blue Sta-bil. Made for marine applications.

The marine stabil states for use during the season. I am not sure it keeps fuel fresh up to two years like stabil red which is for storage. I use the blue during the season and add the red at the end of the season when I winterize.
