Diesel Testing
Diesel Fuel Testing for Microbial Contamination
Diesel fuel contamination, commonly referred to as “diesel bug,” poses serious risks to the efficiency and reliability of diesel engines, especially in emergency, backup, or standby generators. The most common cause of contamination is water ingress—often from condensation—which encourages bacterial growth. Over time, this creates a biomass that forms sludge within the diesel tank, clogging filters and reducing engine performance.
Even without contamination, diesel fuel deteriorates naturally, producing fine sediment throughout the fuel system. Left unchecked, this leads to reduced efficiency, frequent filter blockages, increased fuel consumption, and expensive damage to key components.
How Diesel Bug Affects Your Systems
Contaminated fuel impacts your diesel-powered equipment in multiple ways:
- Engine failure due to fuel starvation
- Corrosion of fuel tanks, piping, and valves
- Injector damage and in-line instrumentation failures
- Pipe blockages and increased water content
- Fuel breakdown, reducing lubricity and increasing friction
- Frequent filter blockages requiring replacements and causing higher fuel consumption
Our experienced generator service engineers provide comprehensive diesel fuel system cleaning. Using portable fuel polishing systems with Racor filtering, magnetic flux bacteria filtering, and high-volume pumping, we remove microbial contaminants, sludge, and moisture from your diesel fuel and tanks. With our services, you can restore engine efficiency, prevent costly downtime, and protect your equipment from further damage.
