    Key

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

*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 transmission: 500 hours.
  • Off-highway final drive: 1,000 hours.
  • On-highway transmission: 500 hours, 40,000 km or 25,000 miles.

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