STA-BIL 360® Marine™ – 8oz

STA-BIL 360 Marine is a fuel treatment made for boats, jet skis and other watersport engines. Ethanol fuel pulls in moisture, and on the water that means rust and corrosion in the fuel system. This treatment coats the metal parts of the fuel system and combustion chamber to protect them, even when the engine isn’t running.

• 1 oz treats up to 10 gallons, so this 8 oz bottle treats 80 gallons.
• Use at every fill-up, or before storage to keep 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.
• No alcohol in it. Made in the USA.

Storing a motorcycle instead of a boat? Grab regular STA-BIL Fuel Stabilizer. It treats 2.5 gallons per ounce and keeps gas fresh for up to 24 months in storage, which suits a bike parked for the winter.

Bigger sizes of 360 Marine (10 oz, 32 oz and a gallon) are in the same Storage Maintenance section if you run a bigger tank or a few watercraft.
