THE TRUE COST OF CONTAMINATED FUEL
What You Can't See Can Cost You Thousands
Modern common-rail diesel engines operate at pressures exceeding 30,000 PSI, where even microscopic contamination can cause catastrophic fuel system failure.
The images shown are from a recent repair where contaminated fuel caused the high-pressure fuel pump to fail. Once the pump broke down internally, metallic particles were circulated throughout the entire fuel system, damaging injectors, fuel rails, lines and associated components.
Common Sources of Fuel Contamination
Water
Dirt and dust
Rust and corrosion
Microbial growth ("diesel bug")
Fuel degradation
Metallic wear particles
The Result
Fuel contamination can lead to:
High-pressure fuel pump failure
Injector damage
Loss of power and poor performance
Hard starting
Increased fuel consumption
Limp mode and engine warning lights
Complete fuel system replacement
In many cases, a relatively minor fuel quality issue can quickly escalate into a repair costing many thousands of dollars, together with significant vehicle downtime.
Prevention Is Far Cheaper Than Repair
Protect your investment by:
✔ Purchasing fuel from reputable suppliers
✔ Replacing fuel filters at scheduled intervals
✔ Inspecting for water contamination
✔ Addressing warning lights immediately
✔ Maintaining your fuel system correctly
✔ Considering quality pre-filter systems, particularly for fleets, motorhomes, mining equipment and vehicles operating in remote areas.
Protect Your Engine Before It's Too Late
If your vehicle experiences hard starting, reduced power, rough running or fuel system warning lights, have it inspected promptly. Early diagnosis can prevent extensive damage and minimise repair costs.
At Viking Group Queensland, our technicians use advanced diagnostic equipment and specialist fuel system testing to identify contamination before it becomes a major failure.
