Bell Performance
Bellicide Biocide Treatment
Bellicide is a professional-grade, broad-spectrum fuel biocide that eliminates and controls microbial contamination in stored fuels. Active in both the fuel and water phases, it kills bacteria and fungi at the source to help protect fuel quality, prevent corrosion, and improve long-term storage reliability.

Product Details
Eliminate Microbial Contamination Before It Damages Your Fuel System
Bellicide is a commercial-grade fuel biocide formulated to eliminate bacteria and fungi that contaminate stored fuels. Whether you're maintaining diesel, biodiesel, gasoline, heating oil, or other finished fuels, Bellicide helps stop microbial growth before it leads to clogged filters, fuel degradation, corrosion, and costly equipment downtime.
Designed for long-term fuel storage applications, Bellicide is trusted by fuel service companies, generator maintenance providers, fleet operators, hospitals, municipalities, marine operators, industrial facilities, and anyone responsible for maintaining clean, reliable stored fuel.
Kills Microbes Where They Live
Microbial contamination develops wherever fuel and water coexist. Bacteria and fungi colonize the fuel/water interface, forming biofilms that allow contamination to spread throughout the storage system.
Unlike products that remain primarily in the fuel, Bellicide partitions into both the fuel and water phases, allowing it to contact and eliminate microorganisms wherever they are growing. This dual-phase activity makes it highly effective for treating contaminated storage tanks.
Protects Fuel Quality and Equipment
Microbial contamination doesn't just affect the fuel—it affects the entire storage system. As microbes multiply, they accelerate fuel degradation, produce corrosive acidic byproducts, create sludge, and plug fuel filters. Left untreated, microbial contamination can lead to expensive maintenance, reduced equipment reliability, and shortened fuel life.
Regular Bellicide treatment helps preserve fuel quality, reduce microbial-related corrosion, and maintain dependable system performance during long-term storage.
Compatible with a Wide Range of Fuels
Bellicide is suitable for use in:
- Diesel fuel
- Biodiesel blends
- Gasoline
- Home heating oil
- Heavy fuel oils
- Crude oil
- Refined oils
- Feedstock oils and fats during storage
For Severe Contamination
For storage tanks with heavy sludge accumulation or well-established microbial contamination, Bell Performance recommends using Bell Tank Treatment SDF alongside Bellicide. SDF breaks apart sludge and microbial biofilms, allowing Bellicide to reach and eliminate microorganisms that would otherwise remain protected. Together, they provide a more complete solution for restoring contaminated fuel systems.

Treat Ratio
Bellicide eliminates existing microbial colonies in contaminated systems with a treat rate of just 2.5 fluid ounces per 100 gallons of fuel (200 ppm) or half an ounce per 20 gallons of fuel.
To maintain a microbe-free system environment (maintenance dosage), Bellicide can be added at a treat rate of just 1.25 fluid ounces per 100 gallons of fuel (100 ppm) or half an ounce per 40 gallons of fuel.
At the maintenance dose of 1.25 ounces per 100 gallons, Bellicide imparts a minimum amount of sulfur to the fuel.
Bellicide Biocide Treatment vs. the Competition
Choosing the Right Biocide
| Biocide Treatment | Bellicide | Isothiazalone (i.e. Kathon FP 1.5) |
Boron-Based (i.e. Bio-Bor) |
Carbamate (i.e. Priocide, Aquatreat) |
Water Absorber (i.e. Star-tron) |
|---|---|---|---|---|---|
| Contact time to a complete kill (how long does it take to work?) | Best choice | — | Acceptable | Acceptable | Will not kill microbes |
| Effectiveness after 1 week (is it still working after one week?) | Best choice | Acceptable | — | Acceptable | Will not kill microbes |
| Effectiveness after 4 weeks (is it still working after four weeks?) | Best choice | Acceptable | — | — | Will not kill microbes |
| Sensitivity to pH (do microbial acids in the fuel keep it from working?) | Best choice | — | Acceptable | — | Will not kill microbes |
Note: “Best choice” and “Acceptable” reflect the original comparison chart.
