STA-BIL 360°® Marine™

In marine equipment you use frequently, STA-BIL 360° MARINE should be used AT EVERY FILL UP for ultimate, year round protection against corrosion. If your boat is in storage, one use of the product will stabilize the fuel for up to 12 months (if added to fresh fuel).

One 12 oz. bottle of STA-BIL 360° MARINE treats up to 120 gallons of gasoline. There is also a 40 oz. bottle available that will treat up to 400 gallons of fuel. Use 1 oz. for every 10 gallons of fuel at every fill-up and when storing for an extended period. STA-BIL 360° MARINE is safe to use in ALL gasoline engines, including 4 and 2-cycle, and safe to use in ALL gasoline blends from ethanol-free gasoline to E85.

Once poured into a tank of fuel, STA-BIL 360° MARINE will provide a vaporized corrosion inhibitor coating for up to 12 months in a stored boat or equipment. However, once a tank of fuel is used up, and new fuel is poured into tank, it will be necessary to re-treat the fuel with 360° Performance.

STA-BIL 360° MARINE accomplishes everything our current STA-BIL products offer, including keeping fuel fresh, removing water, cleaning the fuel system and more, but this revolutionary new product provides an exciting new level of protection for ultimate performance. For the first time, STA-BIL 360° MARINE delivers corrosion protection above and below the fuel line by releasing an innovative vapor that coats all metal parts within the fuel system to prevent corrosion.

STA-BIL 360° MARINE offers comprehensive protection by releasing a microscopic corrosion preventing vapor inside the fuel system that coats ALL metals parts, including the fuel tank, fuel sending unit, valves, carburetor, fuel injectors and intake manifold. It’s like fogging oil for your entire fuel system, offering “360 degrees” of corrosion protection and is safe to use in all types of gasoline – from ethanol-free fuel to E85.

STA-BIL 360° MARINE can be used in any gasoline engine, including 2-cycle, but is specifically designed for use in boats and other equipment used in high moisture environments.

The stamp/code on the back of the bottle will help determine the date it was manufactured. For example: 15120-83318-1658. This bottle based on the code was made in April 2015. The first two numbers determine the year and the three numbers tell you what day in the year based on the JULIAN Date Calendar.

No, over-dosage is perfectly OK. However, we do not recommend adding more than 4 times the recommended amount. If more than 4 times has been added we recommend diluting the fuel.

STA-BIL will eventually evaporate, although this can take some time. However, a stain may occur depending on the type of surface it may have been spilled on. To help clean it up, we recommend trying alcohol on wood, vinyl, or other materials, then regular soap and water. For asphalt or concrete, you may use mineral spirits and then rinse with a high-pressure water.
