STA-BIL 360® Marine™ - 1 Gallon

STA-BIL 360® Marine™ is a comprehensive fuel system cleaner engineered for boats, jet skis, and other marine engines to improve performance and engine longevity. Used with every fill-up, this marine fuel additive helps keep engines running cleaner, leaner, and stronger while preventing fuel degradation and system deposits that compromise reliability on the water.

The 1-gallon container delivers efficient dosing—1 fluid ounce treats up to 10 gallons (38 liters) of fuel—making it practical for both weekend anglers and serious offshore boaters. The alcohol-free formulation works across all marine engine types, including two-stroke and four-stroke designs, without compatibility concerns. This extended treatment range means a single gallon covers substantial fuel consumption across multiple boating seasons, translating to consistent fuel system maintenance without frequent repurchasing.

Marine environments present unique fuel storage challenges—ethanol absorption, water contamination, and deposit buildup from seasonal layups degrade performance and increase repair costs. The STA-BIL 360® Marine formula addresses these issues through its 5-in-1 maximizer technology, which stabilizes fuel during storage, cleans fuel injectors and carburetors, reduces emissions, and protects against corrosion. This approach prevents the fuel-related starting issues and rough idle common when boats remain inactive for months, ensuring dependable engine response whenever you're ready to head out.

Whether maintaining a small fishing boat, personal watercraft, or larger marine vessel, consistent fuel system treatment extends engine intervals and reduces unexpected downtime. The straightforward application—simply add to each fuel tank fill—integrates seamlessly into routine fueling without additional equipment or procedures.
