16 oz Hammonds Biobor JF MicroBiocide Diesel Fuel Treatment - 180

In this review of the 16 oz Hammonds Biobor JF MicroBiocide, the bottom line is simple: this is a practical, high-strength treatment for anyone storing or using diesel and similar fuels who needs reliable microbial control. The reviewer found it especially useful for resolving black sludge and restoring fuel cleanliness, and the 1:80 treatment ratio means a small bottle treats a large volume. For operators of backup generators, fleet vehicles, or seasonal heating fuel storage, this product targets the single biggest pain point: bacterial and fungal growth that clogs filters and corrodes tanks.

Key Features

• 180 Treatment Level: A concentrated formula that treats fuel at a 1:80 ratio so a single 16 oz bottle covers up to 1280 gallons, reducing how often you need to buy treatment.
• Broad fuel compatibility: Labeled for diesel, kerosene, biodiesel and home heating oil so the same product works across multiple stored fuels.
• Bacterial and fungi control: Formulated as a biocide to prevent and remove microbial growth that forms sludge and slime in tanks and filters.
• Protects tanks and filters: The treatment helps prevent clogged filters and bacterial corrosion to tanks, reducing maintenance and downtime.
• Lubricity restoration: Adds lubricity back to low sulfur diesel, which helps fuel system components run more reliably over time.
• Certified and tested: Exceeds ASTM standards, meets MI-S-53021A, and is EPA approved and U.S. Coast Guard certified for peace of mind in regulated applications.

Who It's For

This product is best for owners of backup generators, farm and fleet managers, and anyone who stores diesel, biodiesel blends, kerosene, or heating oil for extended periods and needs to prevent microbial contamination. The concentrated 1:80 treatment is particularly useful for large-volume storage where treating many gallons with a single bottle saves time and cost.

Those who should look elsewhere are users with very small, immediate-use quantities who prefer single-use dosing, or anyone requiring a non-biocidal fuel conditioner rather than a microbiocide; this product is specifically designed to kill microbes and break up sludge rather than just condition fuel chemistry.

Pros & Cons
