    Key

  • Included test
  • TAN in lieu of oxidation for select synthetic products
  • Conditional test

*Viscosity reported at 40°C or 100°C, based on oil type or service level.

Analysis may vary by laboratory, product supplied or oil condition.

Sample frequency

Sample at OEM recommended frequency or, for general guidance, begin with:

  • Off-highway diesel engine: 250 hours.
  • On-highway diesel engine: 25,000 km or 15,000 miles.

Adjust frequency based on asset’s economic impact, operating environment, machine age, oil age or sample results trend.
