What the studies showed
14 936 kmLatest operating mileage in the sample table
The used-oil samples showed critical concentrations of copper and other wear elements, with a reduced base number also noted in the final sample. An oil change and investigation of the causes of wear were recommended. These materials are not presented as a positive acceptance report.
Conditions and methodology
In-service sampling and testing at MITs GSM. Conditions, methods and specific samples are detailed in the original documents.
The results relate to the specified samples and equipment. Operating mileage or hours in an individual trial do not constitute a recommended drain interval for other machines. Follow the equipment manufacturer's instructions and all comments in the test reports.
