LubCheck oil and machine diagnostics

Monitor the status of your machinery and prevent damage by carrying out regular lubricant checks and tests!

More reliable operations. Reduced costs.

LubCheck is a globally-recognised diagnostics process based on monitoring machinery status by focusing on oil sample testing.
The basis of oil diagnostics is that lubricants interacting with machinery carry traces coming from normal or irregular operation of machinery, engines, transmission systems or hydraulic systems.

LubCheck helps us in the early detection of possible breakdowns or malfunctions and can avoid expensive repairs or damage build-up. It is very cost-efficient because the cost of regular oil sample tests is usually significantly lower than the cost of repairs of often totally unexpected breakdowns or malfunctions.

Profit from the benefits delivered by LubCheck!

  • early detection of hidden damaging processes
  • discovery of damaging processes that cannot otherwise be detected
  • reduction or elimination of downtime
  • reduction of maintenance costs
  • more accurate and easy-to-plan maintenance
  • oil change cycle optimisation
  • increased vehicle and machinery reliability

LubCheck diagnostics help optimise costs in many different areas.

Unexpected damage can be detected early on and hidden damaging processes arising from irregularly operating vehicles and machinery can be swiftly identified Increase in vehicle and machinery life spans Component spares and maintenance costs reduced
Lubricant use and oil change intervals are optimised Extended oil change cycles

Full use of lubricant charges
Lubricant costs reduced
Equipment condition can be assessed without profound physical intervention; observation of changes in condition is possible Increased vehicle and machinery reliability

Increased vehicle and machinery life spans
Inspection costs reduced
Production and maintenance processes become more predictable and controllable Increased production scheduling efficiency

Downtimes reduced; use of production capacity increased
Unplanned extra expenses reduced
Less used oil and hazardous waste Reduced enviromental impact Neutralisation costs decreased


Operation of LubCheck oil diagnostics

How exactly does oil diagnostics work?

We determinedly analyse and interpret diagnostic information hidden in a drop of oil and use it to optimise maintenance.
During one of our tests, we analyse the metrics of lubricants’ physical and chemical parameters as well as the intensity of their changes, types and quantities of contaminant found and the type and ratio of worn metals. We draw conclusions about information obtained on the correct or improper operation of machinery and the proper or improper selection of lubricants and how best to handle used lubricants.

A complex procedure in four simple steps


Take a sample from the machinery or engine!

For the sampling process, we provide you with sampling vessels, a manual sampling pump and a handbook with an exact description of the sampling process.

Forwarding samples

Record data of the sample identifier and post them to us!

You send us a sample in the sampling vessel package, data sheet attached. Sampling vessels can be posted free of charge.


Physical and chemical tests of the samples are then performed in our MOL LubCheck Laboratory equipped with special and rapid instruments.

The test parameters will vary for each lubricant and machinery type. Click here for further details!
