Sta-bil or Sta-bil 360 Marine?

[Tjames09]

I think the blue stabil marine is meant for every fill up to prevent ethanol damage. I use the blue stabil very tank of gas. Red stabil for storage. 

Lots of fuel has ethanol in it, even 91 octane, only a few stations 91 is ethanol free.

The fuel treatments work 2 ways first it creates a barrier between air and the fuel in the tank much like oil floats on water. This barrier cut down or stops water absorption into the ethanol in the fuel. It also encapsulates the water in the fuel and allows it to be processed thru the fuel system. If you get a slug of water in the fuel no product will separate the alcohol and the water it will settle to the bottom of the tank and the fuel pick up will send it to the carburetor/ efi.

I’ve use Marine Grade Stabil in all my motors, both 2 stroke and 4 stroke, on every fill (fifteen motors in total) for the past 11 years. Never have had a fuel related issue. Well worth it in my opinion.
