STA-BIL 360® Marine™ - 8oz

STA-BIL 360® Marine™ - 8oz is a premium fuel system cleaner and stabilizer engineered specifically for marine engines that spend months in storage or see seasonal use. Whether you're prepping your boat for winter layup, spring commissioning, or maintaining year-round performance, this additive keeps fuel fresh and combustion clean. Every angler and boater who's dealt with varnish buildup, stale fuel deposits, or hard starts after off-season storage understands why professional-grade fuel treatment matters.

The formula works by cleaning fuel injectors and carburetors while stabilizing gasoline to prevent oxidation and gum formation—two of the biggest culprits behind rough idle, hesitation, and weak throttle response on marine powerplants. When added with every fill-up, STA-BIL 360® Marine™ dissolves existing varnish deposits and protects fresh fuel from breakdown, allowing your engine to run cleaner, leaner, and stronger. The 8oz bottle is sized for convenient portability and storage in any tackle box or engine compartment, making it a practical choice for regular maintenance without excess bulk.

This product is ideal for outboard and inboard marine engines that sit for extended periods, including jet skis, fishing boats, pontoons, and cruisers operating on gasoline. Boaters who winterize their vessels or maintain seasonal watercraft will see the most dramatic benefit, though active anglers using their rigs year-round appreciate the cleaner combustion and improved fuel economy. Simply add to your fuel tank at fill-up; no special installation or equipment required. Compatible with all gasoline-powered marine engines and safe for use with both ethanol and non-ethanol fuels.
