JAC M5 / Refine

Differential fluid capacity & service interval

JAC M5 / Refine differential fluid capacity is 3 liters. Service intervals include checks at 10000 km or 8 months, and changes at 3000 km or 3 months and 30000 km or 24 months. The data covers 4 configurations.

Additional Notes

  • The JAC M5 / Refine rear differential holds 3 liters of fluid across both the 1.9CTI and 2.0T engine variants, indicating a consistent housing size between the two configurations.
  • Under normal use conditions, the rear differential fluid change interval is set at 30000 km or 24 months for both engine variants, whichever comes first.
  • A check interval of 10000 km or 8 months applies under normal use conditions, meaning the fluid level and condition are inspected well before a full change is due.
  • A first change only condition is specified separately for both variants, requiring a fluid change at 3000 km or 3 months. A break-in change at such an early interval is associated with flushing out metal particles and contaminants generated during the initial wear-in period of new gear surfaces.
  • The first change only interval of 3000 km or 3 months is notably shorter than the subsequent normal-use change interval of 30000 km or 24 months, reflecting the distinct servicing logic applied to newly manufactured drivetrain components versus those already in regular service.
