¿What is a fuel additive?

A fuel additive is a chemical compound added to fuel with the purpose of enhancing its quality, performance, and efficiency. These additives can serve various functions, such as cleaning and protecting fuel systems, improving lubrication, preventing corrosion, and reducing pollutant emissions. Their goal is to optimize combustion and engine operation, leading to improved vehicle performance and extended component lifespan.

Can Aditivos Help with Engine Maintenance?


Yes, aditivos can contribute to better engine maintenance. These chemical compounds added to the fuel can clean and protect the internal systems of the engine, prevent deposit buildup, improve lubrication, and reduce corrosion. By keeping an engine cleaner and more efficient, aditivos can help extend the engine's lifespan and maintain its optimal performance over time.

These additives could be considered part of preventive maintenance. Preventive maintenance is a crucial strategy for technicians in the engine industry as it involves planned and regular actions to prevent issues and maintain optimal equipment performance. By applying this approach, technicians can anticipate and address potential failures before they become costly or disruptive problems. In the case of engines, the use of additives in fuels is an example of preventive maintenance as it helps prevent deposit buildup, improves lubrication, and reduces emissions. This not only extends the engine's lifespan but also ensures optimal performance and increased fuel efficiency. Ultimately, preventive maintenance benefits equipment reliability while optimizing technicians' time and resources by minimizing issues and reducing unplanned downtime.

Do you take care of your fuel tank?


Research has revealed that over 75% of analyzed tanks show contamination and contain fuel that does not meet current engine specifications. Proper sampling and comprehensive fuel analysis are crucial to accurately determine the content of your tank. The process can be summarized in three key steps: Test, Treat, and Protect. These simple and effective measures will ensure optimal engine performance and the protection of your fuel system.

Microbial growth and biomass are the main causes of engine problems, motor failures, fuel filter clogs, and fuel tank contamination in diesel and aviation kerosene. Refined fuels nowadays create a highly conducive environment for microbial growth, leading to significant damage in engine and fuel systems. The water content in the fuel is a contributing factor, as even small amounts are sufficient to sustain microbial life. Additionally, biofuels tend to be more susceptible to water. For instance, biodiesel is 85% more soluble in water than conventional diesel fuel, further exacerbating the issue.

¿Why TREAT the fuel?


The only way to effectively eliminate microbial growth or remediate degraded fuel is by treating the fuel with a quality additive. For over 56 years, Biobor JF has been the most reliable and widely used biocide worldwide. It is important to note that cleaning the fuel and tank alone will not be sufficient to eliminate microorganisms or remediate degraded fuel. To effectively address these issues, it is crucial to rely on an additive such as Biobor JF.

Whether you are operating a recreational vehicle, a marine vessel, an aircraft, or a million-gallon storage facility, it is absolutely crucial to consistently and properly use a biocide to prevent microbial issues. Biobor JF provides a highly effective 'shock' dose to eliminate existing growth of bacteria and fungi when problems arise or there are clear signs of contamination. By regularly using Biobor JF at the 'maintenance' dose, you can avoid and maintain a sterile fuel system, protect the fuel system, prolong the lifespan of your equipment, and reduce associated liability. Biobor additives will effectively remediate and enhance the fuel.

¿Do you want to PROTECT your investment?


The use of contaminated fuel results in higher maintenance costs. If you don't have a fuel quality management program in place, you're likely already experiencing some of the major warning signs, which include:


  • Premature filter replacements

  • Corroded filters

  • Fuel system failures

  • Corrosion influenced by microorganisms

  • System leaks

  • Low engine efficiency

  • Line and tank failures

  • Accelerated fuel aging

  • Premature injector failures

  • Engine failures

  • Increased emissions

Inspect and TEST the fuel using the Hum-Bug or FUELSTAT detection kit.


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

Remove Ethanol with: Biobor EB

Hammonds also offers Biobor EB (Ethanol Buster), a product designed to counteract the harmful effects of ethanol in gasoline and improve engine efficiency. Ethanol is highly corrosive and can damage an engine if it is not properly mixed with gasoline. Over time, ethanol tends to separate from gasoline in the tank, but Biobor EB prevents this phase separation, cleans the engine, disperses sediment, and stabilizes gasoline for storage. Biobor® fuel additives are widely distributed nationwide by West Marine and other recognized marine distributors.
