BIOBOR Diesel Fuel Additive 16 oz — Biocide & Lubricity Restorer for ULSD, Prevents Microbial Corrosion

BIOBOR JF is a concentrated diesel fuel biocide and lubricity supplement that eliminates fuel tank microbes, reduces corrosion, and restores lubrication to protect injectors and pumps.

Developed for aviation and adopted by diesel engine manufacturers, BIOBOR JF has a long history of stopping microbial contamination in fuel systems and returning lost lubricity to modern ULSD (ultra-low sulfur diesel). It works in both the water and fuel phases, treating the microbes that form slimy biomass at water interfaces and reducing the acidic by-products that accelerate tank and component corrosion. Use routinely to keep filters cleaner longer, prevent clogging, and protect fuel delivery components from premature wear.

How does BIOBOR JF stop microbial growth in diesel fuel?

BIOBOR JF contains a dual-phase chemistry that targets microbes where they live — in the water layer and suspended fuel — removing existing colonies and preventing new ones from forming. Regular treatment sterilizes the fuel system and reduces the organic sludge that clogs filters and lines.

• Biocide action acts on both bacteria and fungi commonly found in fuel tanks.
• Partitions into water and fuel phases for comprehensive treatment.
• Reduces biomass that causes filter blockages and injector fouling.
• Recommended dosage intervals maintain a sterile tank environment.

Will BIOBOR JF protect my fuel system from corrosion?

Yes — by removing microbial colonies and neutralizing their acidic waste, BIOBOR JF reduces a major source of microbially influenced corrosion in metal tanks and fuel system components. Keeping the water phase free of microbes limits the chemical attack on metal surfaces.

• Prevents acidic by-products that accelerate rust and pitting.
• Limits sludge and deposits that retain moisture against metal parts.
• Helps maintain cleaner tank interiors and longer component life.

Can BIOBOR JF restore lubricity lost in ULSD?

BIOBOR JF restores lubricating properties that refining removes from ULSD, helping protect high-pressure pumps and delicate injector components. Independent ASTM-style testing (HFRR) supports its effectiveness in increasing fuel lubricity to levels that reduce wear.

• Improves lubrication for injectors and fuel pumps.
• Proven to meet or exceed standard lubricity test benchmarks.
• Reduces the risk of premature wear from low-lubricity fuels.

How does using BIOBOR JF affect filter life and maintenance?

By eliminating microbial growth and minimizing biomass formation, BIOBOR JF significantly reduces the rate at which filters become clogged. That lowers downtime, reduces the need for frequent filter replacement or expensive polishing, and preserves fuel system efficiency.

• Decreases frequency of filter changes due to biological fouling.
• Reduces sludge accumulation that leads to fuel polishing.
• Supports predictable maintenance intervals and lowers operating costs.

Who is this for: BIOBOR JF is designed for diesel engine owners and fleet managers, marine operators, aviation ground equipment, military applications, and any vehicle or stationary engine using diesel or jet fuels prone to water contamination. It’s especially useful where fuel sits or cycles slowly, where water intrusion or condensation occurs, or where ULSD has reduced natural lubricity. Choose BIOBOR JF when you want a manufacturer-trusted biocide and lubricity supplement to extend component life and keep fuel systems running reliably.
