BIOBOR Diesel Fuel Additive — 32 oz Biocide & Lubricity Supplement, Dual-Phase Protection Against Microbes and Corrosion

BIOBOR JF is a concentrated diesel fuel biocide and lubricity supplement that eliminates microbial contamination, reduces corrosion, and restores lubrication in ultra-low sulfur diesel.

Designed and trusted since 1965 by aviation, military, and diesel engine manufacturers, BIOBOR JF treats fuel and tank systems to remove and prevent bacteria and fungi, protect metal components from microbially induced corrosion, and return lost lubricity to modern ULSD. This 32-ounce bottle provides an industrial-strength, dual-phase chemistry that works in both the fuel and water layers of a tank, giving comprehensive protection for stored or in-service diesel.

How does BIOBOR JF stop microbial growth in fuel tanks?

BIOBOR JF uses a dual-phase formulation that reaches microorganisms living in both the fuel and water layers, attacking bacteria and fungi where they form masses and slime. Regular treatment sterilizes the tank environment, reducing filter clogging and sludge buildup that can compromise engine operation.

• Penetrates the water phase where microbes thrive and the fuel phase where biofilms form
• Kills existing colonies of bacteria and fungi, preventing re-growth when dosed as recommended
• Reduces sludge and slimy mats that cause filter blockages and injector fouling

Will BIOBOR JF protect fuel system components and prevent corrosion?

Yes—by eliminating microbial activity BIOBOR JF reduces acidic waste products that attack metal surfaces, helping prevent corrosion inside tanks, lines, and filters. The product is also formulated to improve lubricity, which further protects pumps and injectors from wear.

• Limits microbially influenced corrosion caused by bacterial by-products
• Helps maintain cleaner tank interiors and fuel lines, extending component life
• Improves protection for injectors and fuel pumps by restoring lost lubrication

How does BIOBOR JF restore lubricity to ULSD and why does that matter?

Refining ULSD removes natural lubricating compounds; BIOBOR JF replenishes lubrication to meet or surpass industry test criteria, cutting friction and wear in high-pressure injection systems. That reduces premature injector and pump failure and helps maintain efficient fuel delivery.

• Restores lubricity lost during ultra-low sulfur refining processes
• Meets ASTM-referenced performance standards for lubricity protection
• Helps extend service intervals for injectors and fuel pumps

How do I use and dose the 32-ounce BIOBOR JF bottle?

The product is concentrated; follow manufacturer dosing instructions based on tank volume and contamination level for effective treatment. A proactive dosing schedule prevents biofilm formation and maintains sterile fuel conditions over time.

• Dose according to tank capacity and contamination severity—consult label directions
• Initial treatment typically requires a higher dose followed by routine maintenance doses
• Compatible with stored fuel and in-service systems when used as directed

Who is this for: BIOBOR JF is aimed at diesel vehicle and equipment owners, fleet managers, marine operators, aviation ground-support, and anyone who stores or runs ULSD and needs reliable protection against microbial contamination, corrosion, and wear. It is especially useful for operators of long-term storage tanks, seasonal equipment, and high-value diesel engines where preventive maintenance protects uptime and reduces costly repairs.

• KILLS & PREVENTS BACTERIA. Highly effective biocide for bacteria and fungi control in fuel systems, also lubricates delivery components.
• DUAL PHASE CHEMISTRY. Treats both water and fuel layers for thorough microbial control and corrosion prevention.
• EXTENDS FUEL FILTER LIFE. Limits biomass accumulation to reduce filter changes and fuel polishing needs.
• INCREASES LUBRICITY. Restores lubricity to ULSD to protect injectors and fuel pumps.
• OEM APPROVED. Proven performance that meets industry lubricity testing expectations.
