Marine Fuel Additives

Marine Fuel Treatment and Additives for Every Boat Owner

Whether you captain an outboard in saltwater or keep a small vessel docked at a quiet lake, a reliable marine fuel treatment is key to smooth sailing. At Fuel Ox, we specialize in advanced products that clean and protect the entire fuel system, whether you’re using gasoline or diesel.

Our marine fuel additives are formulated to improve efficiency, reduce emissions, and prevent ethanol fuel related damage. Since 2014, we’ve been committed to developing cleaner solutions for marine engines that support your equipment and the environment without compromising performance.

Fuel Ox Marine® With Combustion Catalyst Powers Performance

When talking about marine fuel, the conversation starts with Fuel Ox Marine® With Combustion Catalyst. This marine formula is designed to support every part of the fuel system, from fuel injectors to intake valves. It works by improving combustion so your boat gets more power with less waste. This cleaner burn helps reduce smoke, prevents corrosion in your fuel tank, and lubricates key components like carburetors and injectors.

Ethanol in gas can attract moisture and cause deposits, leading to rough performance. This treatment helps clean and protect your system while improving fuel economy. Whether you are filling up a large vessel or a small bottle for the day, this product keeps your boat’s fuel system running cleaner and stronger every season.

Fuel Ox Marine® Winter Shock Protects During Storage

When your boat sits idle during colder months, untreated gas can create fuel related problems that are tough to reverse. Fuel Ox Marine® Winter Shock is a storage stabilizer that preserves fuel fresh for up to two years. This end-of-season formula helps prevent buildup inside your fuel lines, protects against water in the tank, and shields the engine from the harm of ethanol separation.

This powerful solution supports marine engines of all types and was made to eliminate the need to drain the fuel tank before long periods of rest. Just pour the treatment into the tank, let it mix with the fuel, and your investment stays protected through every part of the off season.

Marine Fuel Treatment Keeps Boats Running Clean and Smooth

Fuel Ox understands that marine environments are tough on gear, and ethanol makes it worse. A trusted marine fuel treatment does more than maintain performance. It helps fight moisture, oxidation, and corrosion. Marine fuel systems are complex, and one contaminated filter or fouled injector can lead to downtime and unnecessary expenses that could have been avoided.

This is why we created a treatment that supports the fuel tank, fuel lines, and every injector inside. When gas or diesel is treated correctly, the system stays clean, which allows your boat to run better and last longer. No more dealing with rough starts or clogged carburetors during the season.

Fuel Stabilizer for Boats Prevents Fuel Breakdown

Leaving untreated fuel in your boat can result in expensive problems. When water collects inside the tank or ethanol starts breaking down, small engines are often the first to show signs of damage. Our stabilizer product is formulated to keep gas and diesel fresh, even when the boat is in long-term storage.

Whether it’s a fishing skiff or a cruiser, Fuel Ox stabilizer guards against ethanol fuel related damage by bonding with the moisture and neutralizing it. This process protects the engine and fuel lines while also supporting filter function and reducing the risk of varnish buildup. Add it before your last fill of the season and let the treatment work while you rest.

Marine Fuel Additives Support Engine Longevity

Years of experience with marine equipment taught us that fuel related problems don’t just affect the engine, they affect the entire system. From fuel injectors to intake valves, our marine fuel additives are designed to clean, lubricate, and stabilize. That means smoother starts, more reliable performance, and better combustion during every trip.

Our marine formula helps prevent the damage caused by ethanol, especially when boats sit idle. Additives like ours work across the entire fuel system and extend the life of both the fuel and the engine. The result is better use of your oil, fewer performance complaints, and a system that stays clean and protected for the long haul.

Gas Additive for Boats Optimizes Every Fill Up

Gasoline used in boats often includes ethanol, which can lead to water separation and corrosion. A good gas additive for boats helps counter those effects and keeps your fuel system healthy. Fuel Ox products are formulated to support both small and large engines, and the additives help clean deposits from injectors and carburetors.

For those tired of rough idle or stalling at the dock, this treatment offers consistent results. We developed this marine fuel product to work well across all boat types. Whether you’re running outboard motors or inboard setups, these additives enhance performance and protect the components that matter most.
