Lubricant, Fuel & Coolant Analysis Testing — Brisbane & Queensland
Every lubricating oil tells a story. As oil circulates through your equipment, it picks up information about what is happening inside — wear particles from component surfaces, contaminants from the environment, water from condensation or seal failure, and the by-products of the oil’s own degradation. Oil analysis reads that story and translates it into actionable intelligence for your maintenance team.
Without analysis, lubricant condition is largely invisible. You can change oil on a time or hour-based schedule, but you cannot know whether the oil was still serviceable — or whether it had already degraded beyond its protective capability. Oil analysis takes the guesswork out of lubricant management, allowing you to extend drain intervals safely where the oil is in good condition, and to intervene early where it is not.
KPL utilises independent laboratories that specialise in lubricant, fuel and coolant analysis — ensuring objective, accurate results with no commercial bias towards any lubricant brand. We manage the sampling process, provide context around the results and recommend the appropriate corrective action where issues are identified.
What Oil Analysis Gives You
- Early warning of component wear — catch bearing, gear and pump failures before they happen
- Contamination identification — pinpoint the source of water, particles, fuel dilution or coolant ingress
- Informed drain interval decisions — extend oil life safely where the oil is still performing, or change early where it has degraded
- Maintenance planning data — trend analysis over multiple samples builds a picture of how equipment condition is changing over time
- Warranty protection — documented oil analysis records demonstrate compliance with OEM maintenance requirements
- Reduced unplanned downtime — acting on analysis results prevents the failures that cause unscheduled shutdowns
- Lower overall maintenance costs — the cost of an oil sample is a fraction of the cost of a component replacement or unplanned outage

Common Test Parameters
| Parameter | What it measures | What it tells you |
| Viscosity | Resistance to flow at operating temperature | Oil thinning (dilution/degradation) or thickening (oxidation, contamination) |
| Acid Number (TAN) | Total acid content of the oil | Oxidation and degradation — high TAN indicates oil life is depleted |
| Base Number (TBN) | Remaining alkaline reserve (engine oils) | Ability of the oil to neutralise acids — when TBN drops, protection is lost |
| Water Content | Free or dissolved water in the oil (ppm or %) | Seal failure, condensation, coolant ingress — water causes corrosion and reduces lubrication |
| Particle Count / ISO Code | Number and size of particles per millilitre | System cleanliness — compared against OEM ISO target for your equipment |
| Wear Metals (ICP) | Concentration of metals in solution (iron, copper, aluminium, chromium etc.) | Component wear rates — elevated metals indicate specific component deterioration |
| Contamination Elements | Silicon, sodium, potassium and other external contaminants | Dirt ingress, coolant contamination, cross-contamination with other fluids |
| Varnish Potential (VPR/MPC) | Tendency of the oil to form varnish deposits | Critical for turbine and compressor oils — predicts varnish-related failures before they occur |
| Oxidation / Nitration | Infrared measurement of oxidation by-products | Oil degradation from heat and combustion — indicates remaining oil life |
How the Oil Analysis Process Works
- Sampling
KPL provides sampling bottles and instructions, or our team can attend site to take samples from your equipment. Correct sampling technique is critical — samples taken from the wrong location or at the wrong time can produce misleading results. We advise on sampling points and methods to ensure your data is accurate. - Laboratory Analysis
Samples are sent to KPL’s independent, accredited laboratory partners for testing. Turnaround is typically 3–5 business days for standard analysis, with express options available where required. Laboratories specialising in lubricant, fuel and coolant analysis are used — not general-purpose labs. - Results & Interpretation
Results are returned with a condition assessment — normal, caution or critical — for each parameter tested. KPL reviews the results in the context of your equipment and operating conditions, and provides clear, practical recommendations on what action to take. - Action & Trending
Where action is recommended — a filter change, lubricant top-up, system flush or lubricant replacement — KPL can supply the products or services required. Repeat sampling over time builds a trend record that supports accurate maintenance forecasting and extends the value of each individual test.

FAQ...
Testing frequency depends on the equipment criticality, the operating environment and the oil type. As a general guide: hydraulic systems and gearboxes — every 6–12 months or every 2,000 operating hours; diesel engines — every 250–500 hours; turbines and compressors — every 6 months or at every major service. For critical or high-value assets, more frequent sampling gives earlier warning and more accurate trend data. KPL can help you set up a sampling schedule appropriate for your equipment.
Yes — in many cases. If analysis results show that the oil is still within specification after its scheduled drain interval, the interval can be safely extended. This reduces oil consumption, labour costs and downtime from unnecessary oil changes. However, extensions should only be made on the basis of actual analysis results — not assumed. KPL can advise on what condition parameters need to be met before an extension is appropriate for your specific oil and application.
Oil analysis is one of the most cost-effective maintenance investments available. A standard lubricant analysis typically costs far less than an hour of unplanned downtime or a single component replacement. Contact KPL on 1300 30 88 66 for current pricing on individual tests and analysis packages.
