Why use fuel polishing?

Marine fuel polishing is essential for maintaining the health and efficiency of your boat's engine. Over time, diesel fuel can become contaminated with water, sediment, bacteria, and fungi, which can lead to clogged filters, corrosion, and ultimately, engine failure. By using a professional fuel polishing service, these contaminants are effectively removed, ensuring that your fuel remains clean and your engine runs smoothly. This preventive measure not only extends the life of your engine and fuel system but also enhances fuel efficiency, reduces maintenance costs, and minimizes the risk of unexpected breakdowns. For boat owners who rely on their vessels for both recreational and commercial purposes, maintaining optimal fuel quality is crucial for safe and reliable operation.

Marine Fuel Polishing

Prevent unexpected engine shutdowns with a proactive fuel tank cleaning program from OJ's Fuel Polishing. Our services help you avoid bad fuel issues and keep your engine running smoothly.

  • Prevent Bacteria and Fungus: In diesel fuel tanks, colonies of filter-clogging bacteria and fungus grow at the fuel/water interface. These colonies produce acidic sludge that corrodes tanks and engine components.

  • No Water Buildup in Fuel Tanks: Even if engines are regularly exercised and operate properly, free and emulsified water can accumulate inside the fuel tank from condensation, leaky tank openings, and fuel deliveries with high water content. As temperatures drop at night, water condenses out of the fuel and builds up inside the tank.

  • Prevent Fuel Filter Clogging Microbes: When the fuel/water interface rises high enough to reach the engine’s fuel supply tube—often inches above the tank bottom—filter-clogging microbes can be drawn into the fuel system and cause engine failure.
