Description
PMX 145 Fuel Biocide – Diesel, Biodiesel & ULP Microbial Control
PMX 145 is a high-performance fuel biocide designed to eliminate and prevent microbial contamination in diesel, biodiesel, and ULP (unleaded petrol) storage and fuel systems. Microbes such as bacteria, fungus, yeast, and mould grow where fuel meets water, producing sludge, acids, and corrosion that block filters and damage pumps and injectors.
PMX 145 stops contamination at the source and keeps fuel protected long after treatment.
ASTM D975 (diesel) and ASTM D4814 (ULP/petrol) Verified.
PMX145 – Independently Tested & Verified for Diesel & ULP Fuel
PMX145 has been independently verified to meet and exceed international ASTM D975 (diesel) and ASTM D4814 (ULP/unleaded petrol) standards. This ensures no reduction in fuel stability across both fuel types, with verified compliance with Australian and global fuel quality benchmarks.

Has PMX145 been independently tested?
Yes. PMX145 has been independently tested by an accredited fuel analysis laboratory and verified under ASTM D975 (diesel) and ASTM D4814 (ULP/unleaded petrol) and related fuel standards. These tests confirm PMX145-treated fuel is clean, stable, and meets all international quality requirements for both diesel and petrol applications.
What does ASTM verification mean?
ASTM verification confirms that fuel treated with PMX145 meets strict international standards for lubricity, cleanliness, and overall fuel performance — across both diesel (ASTM D975) and unleaded petrol (ASTM D4814). These certifications scientifically validate the effectiveness of PMX145, demonstrating that it reliably protects engines and maintains operational performance according to internationally recognised testing protocols.
PMX 145 Dosing Instructions
1. Standard Dosing
- Regular Treatment: 1:4000 PMX 145
- Ensures the fuel distribution system remains free from microbial growth.
- Note: Exceeding the recommended dosing provides no additional benefit.
2. Curative Treatment
- For heavily fouled systems: Use 1:2000 PMX 145
- May need to be repeated periodically to maintain microbial control.
- Gross contamination: Physical cleaning may be required to remove debris.
- Debris can be removed 6 hours after PMX 145 application.
3. Application by Vehicle Type
- Road Vehicles: Add PMX 145 directly to the vehicle fuel tank.
- Marine Vessels:
- PMX 145 can be added directly to tanks where manual cleaning is not feasible.
- Filter changes and debris removal may still be required.
- Storage Tanks:
- Add PMX 145 into a flowing fuel stream for optimal distribution.
- Both slug or continuous feed dosing can be used.
4. Important Characteristics
- PMX 145 is not surface active and will encourage water separation, not inhibit it.
- Heavily contaminated debris can be removed 6 hours after dosing.
5. Safety Precautions
- Avoid dermal contact.
- Wear suitable protective clothing including:
- Rubber gloves
- Safety goggles or face shield
- Follow appropriate safety procedures for all handling methods.
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
ASTM Fuel Specification Compliance
PMX 145 protects fuel quality without pushing fuel outside specification. Independently verified for both diesel and ULP:
| Standard | Fuel Type | Test | Result | Status |
|---|---|---|---|---|
| ASTM D975 | Diesel / Biodiesel | Diesel Fuel Specification Compliance | Meets All Requirements | ✅ PASS |
| ASTM D4814 | ULP (Unleaded Petrol) | ULP Fuel Specification Compliance | Meets All Requirements | ✅ PASS |
Recommended Storage Pairing
For additional long-term storage benefits, PMX 145 can be paired with FTC Decarbonizer to improve combustion properties and overall fuel stability during storage.
- PMX 145 — kills and prevents microbial growth
- FTC Decarbonizer — supports cleaner burn and storage reliability
