Water is detrimental to many things and oil is no exception. Water at levels <0.2% is typically the result of absorption. Higher levels usually indicate a source of water ingress which enters a system primarily through seals, breathers, hatches, contaminated top-off oil and fill caps. Internal leaks through elements such as heat exchangers and water…

Setting Acid Number and Base Number Limits
Setting Acid Number and Base Number Limits There is a rule-of-thumb that oil should be condemned at double its new oil Acid Number, or at half of its new oil Base Number. The problem with this rule is that is has too many exceptions to be valid. Rather than identify the valid instances, it is…

Variability in Oil Analysis Results
Variability in Oil Analysis Results Two consecutive samples, at normal sampling intervals from the same machine, are never expected to have exactly the same results, but occasionally the second set of results appears to have either changed by more than a normal amount, or possibly have shifted in a counter-intuitive direction (i.e. gotten better without…

Ferrous Wear Concentration versus PQ Index
Ferrous Wear Concentration versus PQ Index Since elemental spectroscopy is generally accepted as having lower accuracy measuring wear particles larger than approximately 10 microns, most labs employ some form of simple, large particle analysis specific to ferrous content. Ferrous content is chosen not only because it tends to represent the most common metal in machines,…
