Marine Fuel Stabilization & Storage Protection

Marine engines often experience extended periods of inactivity between boating trips or during winter storage.

Over time, untreated gasoline can oxidize and form deposits that may affect fuel system performance.

STA-BIL 360 Marine Fuel Stabilizer helps maintain gasoline freshness and reduce fuel degradation during storage when used according to the manufacturer's instructions.

Treating fresh gasoline before storage can help support easier starting when it's time to return to the water.

Ethanol & Corrosion Protection

Ethanol-blended gasoline can present challenges in marine environments, particularly when fuel is exposed to moisture and humidity.

STA-BIL 360 Marine contains corrosion inhibitors designed to help protect fuel system components against moisture-related corrosion.

This added protection is especially valuable for boats that spend extended periods in storage or operate in humid environments.

Important: Fuel stabilizer does not remove existing water from gasoline or reverse fuel phase separation. Proper fuel storage and maintenance remain essential.

Fuel System Cleaning & Engine Performance

The STA-BIL 360 Marine formula includes cleaning agents designed to help maintain cleaner gasoline fuel systems.

Regular use according to the manufacturer's instructions can help reduce deposit buildup and support consistent fuel delivery.

A cleaner fuel system can contribute to more reliable engine operation, particularly in boats that experience irregular use.

Year-Round Marine Fuel Treatment

Unlike products intended only for winter storage, STA-BIL 360 Marine is designed for regular use throughout the boating season.

It can be added to fresh gasoline as part of routine marine fuel maintenance or before a planned period of inactivity.

The 8 oz bottle is particularly convenient for occasional treatment and smaller gasoline fuel systems.

How to Use STA-BIL 360 Marine

1. Check the treatment ratio printed on the bottle for your intended application.
2. Measure the appropriate amount based on the quantity of gasoline being treated.
3. Add STA-BIL 360 Marine to the fuel tank according to the manufacturer's directions.
4. Add fresh gasoline as directed to help distribute the treatment.
5. For storage preparation, follow the manufacturer's instructions for circulating treated fuel through the engine's fuel system.

Use only the recommended dosage and follow your engine manufacturer's fuel and storage guidelines.
