STA-BIL 360® Marine™ - 32oz

STA-BIL 360® Marine™ 32oz is a fuel system cleaner and stabilizer formulated to optimize engine performance across all marine applications. This product works with every fill-up to maintain cleaner combustion, smoother operation, and consistent power delivery—critical factors for boaters who depend on reliable engines whether patrolling inshore waters or running offshore. The 32-ounce bottle treats up to 320 gallons of fuel, making it economical for both weekend recreational boats and commercial or professional marine operations.

One ounce of STA-BIL 360® Marine™ treats up to 10 gallons of fuel without the use of alcohol, which is critical in saltwater environments where corrosion and varnish buildup threaten fuel system integrity. The 5-in-1 maximizer formula addresses the multiple threats marine engines face: water absorption, phase separation, deposit accumulation, oxidation, and corrosion. This multi-action approach prevents the fuel degradation that occurs during storage or in high-humidity marine conditions, keeping injectors and carburetors clean and fuel lines clear of buildup that reduces throttle response and engine efficiency.

This stabilizer is suitable for all marine engines—outboards, inboards, jet skis, and other watercraft powerplants. Anglers and boat owners who winterize equipment benefit from the long-term fuel preservation, while year-round boaters in warm climates protect against heat-induced varnish and phase separation. The alcohol-free formulation ensures compatibility with modern fuel injection systems and ethanol-blended fuels commonly found at marine fueling stations across North America.

Marine fuel degradation accelerates in salt air and fluctuating temperatures—conditions standard gasoline stabilizers struggle to manage. STA-BIL 360® Marine™ is engineered specifically for these environments, making it a practical maintenance choice for anyone who runs boats in coastal waters, brackish systems, or remote locations where fuel freshness cannot be guaranteed.
