STA-BIL 360® Marine™ – 1 Gallon

A gallon of STA-BIL 360 Marine treats 1,280 gallons of fuel at 1 oz per 10 gallons. That’s the size for big tanks, guide and charter fleets, rental jet skis, or a marina keeping it on the shelf.

It’s an ethanol treatment you can use at every fill-up. Ethanol fuel attracts moisture, and in a marine fuel system that turns into rust and corrosion. 360 Marine coats the metal parts of the fuel system and the combustion chamber, and the coating keeps working while the boat sits. Used before storage, it keeps marine fuel fresh for up to 12 months.

• Works in ethanol-blended and non-ethanol marine fuel.
• STA-BIL says it cleans out carbon, gum and varnish and helps fuel burn more completely.
• For boats, jet skis and other watersport engines.
• No alcohol. Made in the USA.

Easy way to dose from a gallon jug: pour a few ounces into a marked measuring cup instead of guessing off the jug.

If what you’re storing is a motorcycle, skip this one and get regular STA-BIL Fuel Stabilizer, which keeps gas fresh for up to 24 months in storage.
