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.
