FPPF KILLEM Fuel Biocide 16 oz — Treats up to 1,920 gal, Controls Bacteria & Fungi

KILLEM is designed for tank owners, fleet managers, and maintenance technicians who need a concentrated microbial control treatment for stored diesel and fuel oil. This 16 oz bottle provides a high-use dosage that helps reduce microbial contamination and the associated operational problems in fuel systems. As an EPA-registered biocide, KILLEM targets bacteria and fungal growth that contribute to sludge, slime and corrosion risk inside storage tanks and fuel lines.

How quickly does KILLEM start working in contaminated fuel?

Results depend on contamination level and mixing, but KILLEM begins acting on bacteria and fungi once properly mixed into the fuel. Visible reductions in sludge and slime often appear after initial treatment and subsequent polishing or filtration, with improved fuel clarity over days to weeks.

• Fast biochemical action once dispersed into the fuel column
• Works on both bacterial and fungal contaminants
• Best results when combined with tank cleaning or filtration

What volumes and dosage does one 16 oz bottle treat?

A single 16 oz bottle of KILLEM treats up to 1,920 gallons of diesel or fuel oil using the manufacturer’s recommended dose rates. This high concentration makes each bottle suitable for large tanks, seasonal treatment, or routine preventative maintenance across multiple smaller tanks.

• One bottle treats up to 1,920 gallons
• Adjust dose based on contamination severity and tank size
• Follow EPA registration and label dosing instructions for safe use

How should I apply KILLEM to my fuel tanks?

Apply KILLEM by measuring the correct dose and adding it directly to the fuel tank, then circulating or blending to ensure even distribution. For best outcomes, combine treatment with fuel polishing, filtration, or tank cleaning when heavy contamination or sludge is present.

• Measure and add product to the fuel according to label directions
• Circulate or blend fuel to disperse the biocide evenly
• Consider tank cleaning or filtration for heavily contaminated systems

Will KILLEM protect fuel system components from damage?

KILLEM’s function is to reduce microbial growth that can accelerate corrosion and clog filters; it is not a corrosion inhibitor itself. By reducing biological contaminants, you lower the risk of microbially induced issues that contribute to component wear and filter blockages.

• Reduces microbial slime that can clog filters and lines
• Lowers conditions that promote microbial-influenced corrosion
• Supports better fuel handling and longer filter life when used regularly

Who is this for: KILLEM is intended for commercial and industrial fuel managers, fleet operators, agricultural users, mariners, and property owners responsible for diesel or fuel oil storage. Choose this product if you want an EPA-registered, concentrated biocide to treat large volumes of stored fuel and to help manage microbial contamination as part of regular tank maintenance.
