The Biobor® Family of Fuel Additives

Experience Counts

Hammonds Fuel Additives, Inc. is an innovative, industry leading manufacturer of fuel biocides and additives serving some of the largest fuel users and industries worldwide. Our flagship product, Biobor®JF, continues to be one of the most trusted and widely used fuel biocides for preventing microbial growth and preserving fuel quality. With over 56 years of proven reliability in aviation, refineries, terminals, fleets and diesel end users. Our extensive pedigree of OEM approvals and effective use continues. Hammonds also offers a comprehensive line of diesel, gasoline and aviation fuel products to address all of your fuel quality needs and ensure your equipment, vehicles, engines and facilities operate at peak efficiency, with the highest quality fuel.

Premium Products, Unmatched Pedigree

Since 1965, we are proud to have earned a laundry list of recommendations and approvals from some of the largest diesel engine, turbine engine, airframe and fuel users across the globe. Biobor®JF is mentioned specifically in numerous operation manuals for solving fuel contamination issues and is the ONLY available and approved biocide for use in aviation jet fuel! The complete line of Biobor® products continue in this pedigree and provide the same level of trust and proven performance as expected from its long track record with Biobor®JF.

So when you are choosing a fuel additive, don’t take our word for it… trust the products proven at 30,000 feet and recommended by OEMs worldwide.

What’s in YOUR TANK?

Research shows that over 75% of tanks sampled are contaminated and contain fuel that does not meet current engine specifications. Sampling and testing the fuel is the ONLY way to determine what is in your tank. Its as simple as Test, Treat and Protect.

Microbial growth and biomass are the leading causes of engine shutdown, engine failure, fuel filter plugging and fuel tank contamination in diesel and jet fuel. Today’s refined fuels create an environment even more conducive to microbiological growth, which will cause serious damage to engine and fuel systems. Water is a contributing factor and it only takes a small amount to support microbial life. Fuel always has some level of water content. Biofuels also tend to be more water friendly. Biodiesel is 85% more water soluble than conventional diesel fuel, adding to the problem.

Why TREAT the fuel?

The only way to kill microbiological growth or remediate degraded fuel is to treat the fuel with a quality additive. The most trusted and widely used biocide in the world for over 56 years is Biobor JF. Fuel and tank cleaning on its own will not kill microbes or remediate the fuel.

Whether you operate a recreational vehicle, a marine vessel, an aircraft or a million gallon storage facility, the proper and consistent use of a biocide is imperative to preventing microbial issues. Biobor JF provides a highly effective “shock dosage” (killing existing growth) to eradicate bacteria and fungi when issues arise or signs of contamination are evident. Regular use at the “maintenance dosage” of Biobor JF will prevent and maintain a sterile fuel system, protect the fuel system, extend the life of your equipment and reduce liability. Biobor additives will remediate and enhance the fuel.

Want to PROTECT your investment?

Dirty fuel equals higher maintenance costs. If you do not have a fuel quality management program in place, then you are already seeing some of the major warning signs including:

  • Premature filter replacements
  • Corroded filters
  • Fuel system failure
  • Microbial influenced corrosion
  • System leaks
  • Poor engine efficiency
  • Line and tank failure
  • Accelerated fuel aging
  • Premature injector failure
  • Engine failure
  • Increased emissions

Sample and TEST fuel with Hum-Bug Detector Kit or FUELSTAT.

  1. Identify free water and remove immediately
  2. Visually inspect the fuel – if it looks bad, it is bad
  3. Test for microbial growth using Hum-Bug or FUELSTAT
  4. Look for corrosion – another sign of microbial contamination – if present, treat the fuel

Clean, remediate and TREAT your fuel using Biobor Products

  1. Find microbes, corrosion or aged fuel – treat
  2. Treat with Biobor JF to kill microbial contamination and protect your fuel
  3. Remediate with Biobor fuel additives to improve fuel quality and operability

Monitor, maintain and PROTECT your Fuel with Biobor

  1. Perform monthly fuel sampling and biannual testing to identify changes in fuel quality
  2. Treat fuel with Biobor JF quarterly to reduce system corrosion and keep your fuel clean
  3. Use Biobor Fuel Additives for seasonal protection

Improved Fuel Quality

You’re probably familiar with the Biobor® name. Originally developed and formulated by U.S. Borax in 1965, Hammonds Fuel Additives, Inc. has owned and marketed the flagship Biobor®JF brand for nearly 30 years. Jet and diesel engine manufacturers have come to recommend this outstanding additive in many of their operating manuals as the preferred industry standard fuel additive for eliminating Hydrocarbon Utilizing Micro-Organisms (HUM Bugs) in fuel tanks.

Other Biobor Products

Biobor MD (Marine Diesel) is a cutting-edge over-the-road fuel conditioner engineered to enhance fuel performance, increase fuel lubricity and lowering the cold pouring point(CFPP) by up to 25 degrees Fahrenheit. Biobor MD increases the cetane level for easier cold starting and cleans the entire system of sludge. Treating your fuel regularly with Biobor MD provides more available horsepower, torque, and fuel economy while reducing up to 94% of soot output and carbon buildup.

Hammonds also offers Biobor EB (Ethanol Buster) to combat the harmful effects of ethanol in gasoline and increase engine efficiency. Ethanol is extremely corrosive and can be detrimental to your engine if not properly blended with gasoline. Over time ethanol will separate from the gasoline in your tank. Biobor EB prevents fuel phase separation, cleans the engine, disperses sludge and stabilizes gasoline for storage. The Biobor® Family of Fuel Additives are distributed nationally by West Marine and other fine marine distributors.

All the Fuel, All the Time®
