The test methods and limit values given in Table 4 and Table 5 (Analytical Limit Values for Diesel / Gas Engine
Oils) indicate when the results of an individual oil sample analysis are to be regarded as abnormal.
An abnormal result requires immediate investigation and remedy of the abnormality.
The limit values relate to individual oil samples. When these limit values are reached or exceeded,
an immediate oil change is necessary. The results of the oil analysis do not necessarily give an
indication of the wear status of particular components.
In addition to the analytical limit values, the engine condition, its operating condition and any
operational faults are decisive factors with regard to oil changes.
Some of the signs of oil deterioration are:
• Abnormally heavy deposits or precipitates in the engine or engine-mounted parts such as oil filters,
centrifugal oil filters or separators, especially in comparison with the previous analysis.
• Abnormal discoloration of components.
