Diesel Fuel Biocide - Power Service Bio Kleen 16 oz

In this review of Power Service 09016-09 Bio Kleen Diesel Fuel Biocide, the bottom line is simple: this 16 oz formula is aimed at diesel owners who store fuel or operate equipment in humid conditions and need a targeted solution to kill microbes. The reviewer found it useful for addressing mucous-like deposits and reducing filter clogging when microbes are suspected, and it performed as a straightforward diesel system treatment rather than a polish or additive for power gains. For anyone worried about microbial contamination, this product is a focused maintenance option.

Key Features

• Dual-phase action: Designed to work in both diesel fuel and water layers, so it treats microbes wherever they grow inside the tank.
• Microbe elimination: Formulated to remove bacteria and fungus that form mucous-like accumulations and foul fuel filters.
• Manufacturer alignment: The dual-phase approach is the type recommended by major diesel engine manufacturers for microbial control.
• Simple dosing: Supplied as a concentrated 16 oz bottle that can treat stored or in-service fuel without complex mixing equipment.
• Maintenance focus: Intended to reduce the frequency of fuel-filter replacements caused by microbial growth when used as directed.

Who It's For

Diesel owners with long fuel storage periods, seasonal equipment, generators, or fleets that see mucous-like deposits on filters will find this product particularly useful. It is most relevant to those who need a targeted diesel fuel biocide that addresses both fuel and water phases to limit recurring contamination.

Those seeking performance additives for power, detergency for injectors, or lubricity improvements should look elsewhere; this product is specifically a microbial treatment and not a multi-purpose fuel enhancer.

Pros & Cons

Pros

• Effective at targeting both fuel and water-based microbes, helping clear mucous buildup that clogs filters.
• Receives positive feedback for functionality and overall quality in customer reports.
• Concentrated 16 oz size is convenient for treating single tanks or spot treatments without large volumes.

Cons

• Some customers report mixed results on sputter resistance and long-term bacteria resistance, so outcomes can vary by tank condition.
• Opinions differ on value for money; some find it costly for routine use depending on application frequency.

Frequently Asked Questions

Will this remove all types of microbes in a tank?
It is formulated to remove bacteria and fungus present in diesel and the water layer, but results depend on contamination level and following dosing instructions.

Can it improve engine performance?
Its purpose is microbial control and reduced filter fouling; it is not formulated primarily to increase power or restore injector cleanliness.

How often should it be used?
Use as a treatment if microbial contamination is suspected or as part of routine maintenance on stored fuel; frequency depends on storage conditions and manufacturer guidance.
