## Description

Biobor JF - All Fuels, Always! Biobor JF has been the most widely used and recommended fuel biocide and lubricant for over 56 years. Highly recommended by many leading diesel engine manufacturers, the Biobor JF eliminates and prevents the growth of microorganisms in fuel and dramatically extends the life of the filter. In addition, the Biobor JF returns to ULSD lubrication, protecting injectors and fuel pumps while preventing corrosion. Trust Biobor JF, the world standard since 1965 for engine life and fuel quality. Why use Biobor JF? Since 1965, Biobor JF has been the world standard for microbial proliferation in fuel. Originally developed for use in commercial and military aviation industries, the Biobor JF continues to provide proven reliability and effectiveness in numerous diesel industries for over 56 years. In addition to this impressive genealogy, Biobor JF is the only diesel biocide recommended by names by many of the leading diesel engine manufacturers around the world. Microbial Proliferation: When debating diesel fuel problems, the growth of microorganisms is widely known as the most common cause of fuel related engine failures. Essentially, diesel fuel and fuel tanks tend to accumulate water, even if condensation in a tank, water infiltration due to the fuel supply, or simply receive a bad batch. To further worsen this problem, today's ULSD carries much higher concentrations of water well and provides a breeding ground for HUM bugs (or microorganisms that utilize hydrocarbons). Humbugs live in the water phase of the fuel tank, developing a dark, slimy gel-like mat that eats fuel. As the colonies of bacteria and fungus grows (which can multiply every 20 minutes), fuel filters and plug injectors can quickly clog and lead to excessive sludge buildup. Furthermore, its waste is one of the main causes of corrosion in fuel tanks and metal parts. With continued use of Biobor JF, the growth of microorganisms is eliminated from the fuel system, creating a sterile fuel system, extending the life of the fuel filter and preventing corrosion problems. Lubrication of Ultra Low Sulfur Diesel: Since the introduction of ULSD, engine manufacturers have recognized and encouraged the need for additional lubrication in today's diesel fuels. The refining process required to lower sulfur levels has greatly reduced the natural lubrication properties of diesel fuels. Diesel engine owners are influencing these systems which are essential for the protection and longevity of the injection system and fuel pump. Biobor JF is proven to exceed ASTM standards to protect injectors and pumps from premature wear and restore these lubrication levels. (ASTM-D6079 HFRR-ENGINE MANUFACTURER AND INDUSTRY STANDARD TEST) One product used by engine manufacturers, civil airlines, US military, diesel boat operators and Biobor JF solves the two most common problems engine owners face.

## Questions & Answers

**Q: How do I ensure it mixes well when dosing an already-full 285-gallon farm diesel tank?**
A: Ideally, you can add the product prior to receiving a delivery to provide effective mixing. However, if treating a full tank go ahead and add the product and agitate with any available method.  ie. circulation, stirring, etc.  Biobor JF is dual-phase soluble in both fuel and water, so it will begin to migrate through out the tank on its own, it will just be a slower process.  It is better to go ahead and treat the tank and let it mix in time, versus no treatment at all.  Biobor JF provides lasting protection of stored fuel, and will also protect the fuel as it is delivered to the equipment being used for complete coverage.

**Q: I have a 400 gallon tank. For maintence dose: if i fill up (add) with 200 gallons, do I dose for 200 gallons or 400 gallons?**
A: If the fuel that is already in the tank is treated with Biobor  JF then you would only dose for the 200 gallons that you are adding. If the fuel currently in the tank is untreated with Biobor then you would dose for the entire 400 gallons. I hope that this answers your question.

**Q: My RV already has a full tank of fuel, if I add this product and then drive will driving mix it into the fuel?**
A: Ideally, you should add Biobor in the the tank before you fill up. Thats the best mixing in the fuel tank for this product or any additive for that matter. if you have a full tank you can add biobor and drive around to mix it. It will also get into the fuel lines and injectors by running the engine.  Should be fine. Even if i add biobor before a fill up I still run the engines to get it in the full lines and injectors. I have been using Biobor on every fill up and winter storage since 1998 religiously in my boat and i have Never had anything grow in my tank. Never a problem. Its an ounce of prevention.

**Q: How do I ensure it mixes well when dosing an already-full 285-gallon farm diesel tank?**
A: As a rule always put biobor in before a fill up. If not try your best to agitate the tank especially if its going to sit for a while.
