Workboat Diesel Additive and Tugboat Fuel Treatment Solutions

Workboats and tugboats depend on reliable power, strong fuel economy, and reduced emissions to handle demanding jobs across ports, rivers, and open seas. These vessels operate with heavy loads and require a dependable diesel additive to maintain combustion efficiency and keep the entire fuel system running smoothly. Fuel Ox delivers powerful treatment solutions that support diesel fuel integrity, improve fuel efficiency, and protect fuel tanks and fuel lines from degradation and corrosion.

Founded in 2014, Fuel Ox has grown from serving local industries to supporting international workboat fleets with advanced additives and lubricants. Every product is engineered to deliver improved performance, enhance fuel right from the source, and offer long-term value across all marine applications, especially for larger vessels that rely on consistency in extreme environments.

Fuel Ox® Combustion Catalyst for Enhanced Engine Efficiency

Fuel Ox® with Combustion Catalyst is a top-tier fuel additive designed to maximize the combustion process in diesel engines. This concentrated formula increases burn efficiency, reduces soot, and helps prevent clogged filters. Operators see improved fuel economy, fewer regenerations, and longer filter life thanks to its unique fuel treatment chemistry.

Fuel Ox Marine® with Combustion Catalyst offers the same combustion benefits with additional protections against moisture and carbon buildup common in boats. It stabilizes untreated fuel and ensures better flow through fuel lines, making it essential for vessels operating in demanding marine environments where performance and emissions control are critical.

Both of our Combustion Catalyst formulas contain a maintenance dose of biocide to keep your tanks mold free and filter bacteria – something other fuel additives don’t include.

With a 1:10,000 treat rate, our Combustion Catalyst additive is far easier to use, especially in marine applications where boats take on 10,000+ gallons. Competing additives require 10x more product, making Fuel Ox the cleaner, faster solution.

Tackle Heavy Fuel Oil Problems with Fuel Ox® Asphaltene

Diesel engines that run on heavy or blended fuels can suffer from asphaltene sludge buildup and filter plugging. Fuel Ox® Asphaltene breaks down and disperses carbon clusters and contaminants before they clog fuel filters or injectors. This treatment is perfect for boats storing diesel in storage tanks for extended periods, helping extend the life of filters and reduce downtime.

Ideal for treating mixed or lower-grade diesel fuel, this product improves combustion by preventing sludge formation and supporting clean fuel burn. Tugboat and workboat operators using this solution benefit from a cleaner system, longer filter life, and sustained engine performance even under high load and heat.

All-Season and Winter Protection for Marine Diesel

For year-round reliability and for vessels that operate in colder climates, Fuel Ox offers several targeted solutions:

• Fuel Ox® Cold Charge – Helps maintain diesel flow and prevent gelling at the cloud point while enhancing lubricity and cold starts.
• Fuel Ox® Freeze Guard & Fuel Ox® Winter Max – Designed for freezing conditions to protect fuel lines and filters against ice and wax buildup.
• Fuel Ox® Heat Bomb – A recovery treatment that restores flow in gelled fuel systems, providing an emergency fix in freezing weather.

These solutions help keep marine equipment running without interruption and protect the fuel system from harmful moisture, sludge, and clogged filters that can lead to costly repairs and lost operating time.

High-Performance Lubricants for Marine Equipment

Beyond fuel treatment, protecting engine components with the right marine lubricant is key to extending equipment life. Fuel Ox’s Infinity Lube™ line enhances the performance of key parts by reducing friction, repelling water, and resisting corrosion in high-moisture environments.

• Infinity Lube™ Super Grease – Designed for marine joints, steering, and deck equipment, this grease holds up under heavy weight and provides long-lasting coverage.
• Infinity Lube™ Super Spray – A flexible solution for moving components that need regular lubrication, from throttle linkages to boat lift cables.
• Infinity Lube™ Friction Eliminator: Enhances internal metal surfaces in marine engines, gearboxes, and hydraulics, reducing friction, wear, and improving performance in harsh marine conditions.

These lubricants create smoother operation, reduce wear, and help maintain system integrity under constant exposure to water and salt. Whether you’re maintaining engine parts or prepping vessels for the next mission, these additives provide essential protection with each application.

Why Workboat Operators Trust Fuel Ox For Diesel Fuel Additives

Fuel Ox has built a reputation among operators of tugboats, workboats, and commercial vessels for offering fuel additive solutions that increase savings and reduce downtime. From the moment fuel is added to the tank to the last ounce burned in the engine, Fuel Ox helps vessels run cleaner, longer, and more efficiently.

Customers benefit from international shipping, responsive support, and a 30-day return policy that ensures satisfaction. With a focus on cutting-edge performance, we stand behind every bottle, providing long-term protection, improved combustion, and peace of mind for marine fleets worldwide.
