Fuel Contaminants

Fuel Contamination Additives for Microbial Growth in Diesel

When it comes to protecting your fuel and equipment, microbial growth and fuel contamination are not just minor annoyances, they’re serious threats that can cause expensive damage, downtime, and service issues.

At Fuel Ox, we provide fuel contamination additives that tackle sludge, bacteria, corrosion, and fuel degradation with proven results. Whether you’re dealing with a diesel-powered fleet, off-road equipment, or heating oil tanks, we’ve got a solution built to prevent microbial growth in diesel and other middle distillates.

Protect Internal Combustion Engines from Fuel Contamination

If you’re using diesel, gasoline, or heavy fuel oil, microbial growth and water contamination can lead to serious problems, clogged filters, injector failure, corrosion, and breakdowns. That’s where Fuel Ox® with Combustion Catalyst comes in. Our advanced fuel contamination additive works in all internal combustion engines, including trucks, heavy equipment, marine engines, trains, and even passenger vehicles.

By using our patented combustion catalyst, you’re not only improving burn efficiency and reducing emissions but also adding a layer of microbial protection. A maintenance-level biocide is built into the formulation, preventing bacteria and fungi from growing in your tanks. The additive keeps injectors clean, lowers DEF usage, cuts down regeneration cycles, and ensures a longer life for your EGR coolers and sensors.

Stabilize BioFuel blended Heating Oil in Outdoor Tanks

Outdoor heating oil tanks are especially vulnerable in the winter. With high bio-blend fuels, you’re likely to encounter issues like gelling, sludge, and accelerated degradation. Fuel Ox® Star Plus™ Bio was made to address these specific winter challenges in both indoor and outdoor heating oil tanks using B-20 blends and above.

This powerful additive is formulated to reduce microbial growth in diesel-based blends by preventing oxidation and maintaining fuel stability. It lowers the Cold Filter Plugging Point (CFPP), reduces sludge and water contamination, and eliminates corrosion caused by acidity.

Minimize Fuel System Failures in Indoor Heating Systems

For indoor applications using bio-blended heating oil, Fuel Ox® Star Plus™ is your best defense against microbial growth and contamination. Biofuels degrade faster, and indoor systems are still at risk for sludge, gumming, and corrosion due to water exposure and oxidation. Fuel Ox® Star Plus™ stabilizes the fuel, controls microbial activity, and helps prevent internal wear, particularly seals that are destroyed by acidic fuel conditions. The emulsification performed by Star Plus of any water (caused by condensation) in the tank is important as it removes standing water at the bottom of the tank that will, over time, corrode and create leaks in the tank.

Stop Sludge and Bacteria in Heating Oil Tanks

Indoor residential heating oil tanks are prone to developing sludge and bacteria when left untreated. Our Fuel Ox® Heating Oil Treatment is designed specifically for this environment, helping you protect your equipment without needing costly winter emergency repairs.

This additive keeps bio-blends stable by preventing oxidation. It also reduces water-related corrosion and sludge accumulation, two major contributors to microbial growth. Used regularly, it helps extend the life of your fuel system, reducing part replacements and service interruptions during peak heating season.

Why Fuel Ox is the Industry’s Choice for Contaminated Fuel Problems

Since 2014, we have been developing cutting-edge, sustainable fuel solutions that help your engines run cleaner, longer, and more efficiently. Our fuel additives are engineered with your performance, budget, and environmental impact in mind. Whether you’re operating a local fleet, maintaining a backup generator, or managing a commercial heating system, Fuel Ox gives you the power to fight back against microbial contamination and fuel instability.
