Lubricating greases - OELCHECK optimises determination of wear and additive elements
Publication year: 2023
OELCHECK is one of the few laboratories around the world that analyses lubricating greases. As is the case with lubricating oils, determining the wear and additive elements contained in them plays an important role in the examination process. However, unlike lubricant or fuel analysis, there are no internationally applicable standards for carrying out grease analyses. The laboratories therefore use different, often in-house developed, non-validated test procedures, the results of which may differ.
An unsatisfactory situation that requires more clarity! That’s why, using the three most common methods, we took the initiative to analyse over 100 samples of a wide range of used greases.
