The Shell Rapid Lubricants Onboard Plus test kit provides your ship’s engineers with a convenient, immediate, on-the-spot method of testing the condition of the lubricants on your vessel.

It helps to supplement the laboratory-based oil analysis service provided by Shell Rapid Lubricants Analysis (RLA ). The Shell RLA service should be used to obtain regular, accurate, long-term condition monitoring information about both oil and equipment.

The Shell Rapid Lubricants Onboard Plus test kit can rapidly test five important parameters of lubricating oil performance:

  • water in oil
  • insoluble material
  • total base number (TBN) or reserve alkalinity of engine oil viscosity
  • salt-water contamination.

With the test kit, oil can be tested and monitored at any time. Although the results are not as accurate as those obtained from a laboratory, they help to confirm if the oils in use are in good condition, which helps to maintain your equipment’s protection.


  • Simple and easy to use
  • On-board real-time testing to remove the delay of sending samples to the laboratory
  • Testing of engine, gear and hydraulic oils
  • Test cell battery life of at least five years for long-term availability
  • Basic insolubles test for instant indication of excessive soot loading or fuel contamination of engine oils
  • The basic kit contains enough materials for 50 tests
  • All equipment supplied in a rugged portable case
  • An easy-to-read user manual is included
  • No special training is necessary


  • Immediate reliable results available any time, anywhere to fit with your operational schedules
  • Confirmation that your oils are in good condition and your equipment is well protected
  • Rapid test results enable you to take any necessary remedial action immediately
  • A reliable source of data to help you identify maintenance issues and avoid equipment damage
  • Reduced equipment downtime
  • Increase operational profitability and reduced costs
