Case - IH Optum CVX

Differential fluid capacity & service interval

Case IH Optum CVX differential fluid capacity is 17 liters. Service intervals include checking at 300 hours and changing at 1200 hours/12 months or 1500 hours/24 months. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • Front differential capacity across Optum CVX models from 2016-2020 maintains a consistent 17-liter service fill volume regardless of engine displacement or emissions standard.
  • Optum 270 CVX and Optum 300 CVX equipped with Tier 4b or Stage IV emissions technology require front differential fluid checks at 300-hour intervals and complete fluid changes every 1200 hours or 12 months, whichever occurs first.
  • Stage V models introduced in 2020 extend the front differential change interval to 1500 hours or 24 months for both Optum 270 CVX and Optum 300 CVX, representing a 25-percent increase in hours between services compared to earlier emissions standards.
  • Front differential fluid condition monitoring occurs at identical 300-hour check intervals across all Optum CVX configurations, establishing a consistent preventive maintenance checkpoint independent of emissions tier or model year.
  • The transition from Tier 4b/Stage IV to Stage V specifications correlates with extended service intervals while maintaining the same 17-liter capacity, indicating potential improvements in fluid longevity or oxidation resistance in newer formulations.
