Full Product Description
STA-BIL 360 Marine is a specialized “every fill-up” treatment that goes beyond standard stabilization. In a marine environment, ethanol in gasoline can attract moisture, leading to “phase separation” and severe corrosion. This formula uses industry-leading water removal technology to prevent these issues, ensuring your engine starts reliably even after weeks of sitting at the dock.
The standout feature is the Revolutionary Vapor Technology. Unlike standard stabilizers that only protect the fuel they touch, STA-BIL 360 Marine releases a protective vapor that coats the entire inside of the fuel tank and combustion chamber. This prevents rust on the metal surfaces that aren’t submerged in fuel. It also contains powerful PEA (polyetheramine) cleaning agents to strip away carbon buildup, gum, and varnish, restoring lost engine power and fuel economy.
