STA-BIL 360® Marine™ – 10oz

Running a jet ski or a small outboard? The 10 oz STA-BIL 360 Marine treats 100 gallons, which covers a lot of fill-ups on a personal watercraft. Add it every time you fuel up, or before you put the machine away, and it keeps marine fuel fresh for up to 12 months.

Ethanol fuel attracts moisture, and moisture on the water means rust and corrosion in the fuel system. 360 Marine coats the metal parts of the fuel system and combustion chamber, and that coating stays put even when the engine isn’t running.

• Dose: 1 oz per 10 gallons.
• Works in ethanol-blended and non-ethanol marine fuel.
• STA-BIL says it clears carbon, gum and varnish and helps the engine burn fuel more completely.
• For boats, jet skis and other watersport engines. No alcohol. Made in the USA.

This is a marine product. For a motorcycle that’s going into winter storage, regular STA-BIL Fuel Stabilizer is the one to use; it keeps gas fresh for up to 24 months.

Fueling a bigger boat? 360 Marine also comes in 32 oz and a gallon in our Storage Maintenance section.
