What the studies showed
Two test reportsResults for one tractor unit
The first test report assesses the parameters as within normal limits. The latest report states that the acid and base numbers were converging when the oil was drained; the other measured parameters had not reached their limits. The latest file's name contains a mileage qualification, so no universal interval is claimed on that basis.
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.
