STA-BIL 360® Marine™ - 1 Gallon *Case of 4*

STA-BIL 360® Marine™ is a comprehensive fuel system cleaner formulated specifically for marine engines, whether you're running a center console, offshore cruiser, or weekend fishing boat. This 1-gallon case of 4 delivers year-round fuel stabilization and performance enhancement with every fill-up, making it an essential maintenance product for boaters who demand reliability on the water. Used consistently, it keeps fuel injectors clean and combustion chambers free from deposit buildup that degrades horsepower and fuel economy.

The formula works by breaking down varnish and gum deposits that accumulate in fuel lines, carburetors, and injector nozzles—common culprits behind rough idle, hesitation, and hard starts after seasonal layup. STA-BIL 360® Marine™ also contains corrosion inhibitors and water-absorbing compounds that protect fuel system components from rust and phase separation, critical in marine environments where moisture exposure is constant. The advanced chemistry restores lost octane and stabilizes fuel for extended periods, whether you're prepping for off-season storage or maintaining peak performance throughout the boating calendar.

This case quantity suits serious boaters, charter captains, and marine maintenance professionals who service multiple vessels or run high-hour engines requiring consistent fuel system care. Compatible with all gasoline marine engines—inboards, outboards, and jet drives—simply add one ounce per gallon of fuel at each fill-up for optimal results. The 4-gallon bulk format reduces per-gallon cost and ensures you're never without backup bottles during the critical boating season when engine reliability directly impacts safety and enjoyment on the water.
