Description
What Is PMX 145 Fuel Biocide?
PMX 145 is a high-performance fuel biocide designed to eliminate and prevent microbial contamination. This is commonly known as the diesel bug in diesel and biodiesel systems. As a powerful diesel biocide, it works throughout the entire fuel system to protect fuel injectors, filters, and critical engine components.
Unlike many products that treat only one layer, PMX 145 is soluble in both the water and fuel phases. Hence, it remains suspended in the fuel tank to ensure complete system coverage. This makes it a highly effective biocide for diesel across storage, transport, and operational use.
It is also a non-hazardous fuel treatment that keeps fuel compliant and suitable for on-road diesel, marine use, and long-term storage.
The core benefits it provides are:
- Broad-spectrum microbial control
- Rapid killing of bacteria and fungi
- Long-term fuel preservation and reliability
Why Diesel Fuel Needs a Biocide
The diesel bug refers to microbial growth (including bacteria, fungi, yeast, and mould) that forms at the fuel–water interface inside a tank. This contamination feeds on fuel and moisture caused by condensation. It can lead to sludge, acids, and corrosion across fuel system components.
“Diesel algae” is a commonly used term, although no real algae exist in diesel. Instead, this bacterial growth produces a thick, dark mess that contaminates fuel and disrupts system performance.
Some common problems caused by diesel bug contamination include:
- Blocked fuel filters leading to reduced power and engine drop-off
- Damage to fuel injectors, pumps, and fuel lines
- Corrosion in tanks and storage systems
- Poor reliability in generators, marine engines, and site equipment
- Increased smoke, reduced performance, and costly repairs
PMX 145 is specifically formulated as a diesel bug treatment and diesel algae treatment. This helps to control contamination at the source and protect your fuel system long-term.
How PMX 145 Works in Diesel and Biodiesel
PMX 145 delivers a complete solution for microbial contamination through the following multi-stage treatment process:
Full-phase activity in fuel and water
PMX 145 is fully compatible with both fuel and water, which allows it to treat microbes wherever they occur. It remains suspended throughout the fuel system to ensure consistent coverage across the entire tank. This prevents any untreated zones.
Attaches to and kills microbes
Once added, the product activates and targets microorganisms, including bacteria and fungi. It binds to active colonies and, in doing so, eliminates the diesel bug. This stops contamination before it spreads.
Drops sludge and contamination for easy removal
As microbes die, waste material, sludge, and contamination settle at the bottom of the tank. Rather than pushing debris through the engine, this allows operators to drain the system and remove buildup efficiently.
Acts as a long-term biostat
After the initial treatment, the residual product continues to protect the fuel by preventing regrowth. This ensures long-term fuel quality and can extend storage life up to 5+ years in diesel and 2+ years in biodiesel under controlled conditions.
Where to Use PMX 145 – Diesel Bug Treatment for Storage, Marine and Fleets
PMX 145 is suitable for any application where fuel sits long enough for water contamination and microbial growth to occur.
Bulk fuel storage and depots
Treat large storage tanks and fuel reserves at terminals or on-site locations. This helps maintain clean fuel before it reaches vehicles or machinery.
Marine and boating applications
Marine fuel systems are particularly prone to diesel algae due to exposure to moisture. PMX 145 protects engines and prevents blockages that could lead to failures offshore.
Generators and standby power systems
Backup systems rely on clean fuel to operate when needed. Treating stored fuel ensures consistent engine start-up and performance under load.
Commercial fleets and site equipment
It is ideal for vehicles, transport systems, and machinery with low fuel turnover because it helps reduce contamination, improve fuel efficiency, and extend filter life.
PMX 145 can be added directly at multiple points, including terminals, storage facilities, or during fuel delivery. This makes it a flexible and efficient diesel bug treatment.
Safety and Handling for PMX 145 Fuel Biocide
PMX 145 is a non-hazardous fuel biocide when used according to instructions. However, standard handling precautions should always be followed when working with fuel additives.
Recommended safety measures include:
- Avoid direct skin contact
- Wear gloves, safety goggles, or face protection
- Follow site safety procedures when handling fuel or additives
- Ensure proper storage and controlled mixing conditions
Always refer to the product’s MSDS and technical data sheets for full handling instructions and compatibility details.
FAQs
Is PMX 145 a fuel biocide or just a fuel conditioner?
PMX 145 is both a true broad-spectrum diesel biocide and a conditioner. This means that, rather than simply improving fuel performance, it actively kills bacteria, fungi, and other microbial contaminants.
Can I use PMX 145 as a diesel algae treatment in marine fuel?
Yes, PMX 145 is suitable for marine use because it effectively treats the contamination commonly referred to as “diesel algae.” This helps to protect marine engines and fuel systems.
Will PMX 145 affect fuel quality or engine warranties?
No. PMX 145 maintains ASTM D975 compliance. Therefore, it does not negatively impact fuel quality, engine performance, or system compatibility when used as directed.
How long does one treatment of PMX 145 last in storage?
One treatment can last up to 5+ years in standard diesel and around 2+ years in biodiesel. However, this depends on how you store it and whether new water enters the system.
Do I still need to drain water if I use PMX 145?
Yes. PMX 145 helps separate water and drop contamination. But you will still need to drain the tank of water and sludge to achieve the best results.
Can I use PMX 145 with other diesel fuel additives?
PMX 145 is generally compatible with other fuel treatments and additives. It can be paired with complementary products to improve combustion and long-term storage performance.

PMX 145 is a high-performance fuel biocide built to eliminate and prevent microbial contamination in diesel, biodiesel, and ULP (unleaded petrol) systems. Unlike treatments that separate or only work in part of the tank, PMX 145 remains suspended throughout the fuel, delivering full-volume additive coverage.
- Attaches to and Kills Microorganisms
Once introduced, PMX 145 targets active microorganisms including mould, yeast, bacteria, and fungus. It binds to these microbes and kills them, stopping contamination at the source.
- Drops Heavy Contamination Out of Suspension
As microbes die, the contamination agglomerates and settles to the bottom of the tank. This concentrates sludge in the low point, making removal easy via draining, water draw-off points, or tank cleaning.
- Remains in the Fuel for Full-Tank Protection
After the heavy contamination is removed, PMX 145 stays suspended in the fuel, so active biocide remains present across the entire tank and fuel system.
- Acts as a Biostat to Prevent Regrowth
PMX 145 continues working in both the fuel tank and filters, preventing microbial colonies from re-forming and keeping fuel protected long-term.
Proven Long-Term Protection
- 5+ years protection in regular diesel
- 2+ years protection in biodiesel applications
