JAC M3 / Refine
Differential fluid capacity & service interval
JAC M3 / Refine differential fluid capacity ranges from 1,15 to 2,05 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 M3 / Refine M3 1.6 rear differential holds 1.15-1.25 liters of fluid, while the 2.0 variant holds a noticeably larger 1.95-2.05 liters, reflecting the greater physical size of the differential unit in the larger-engined configuration.
- Both the 1.6 and 2.0 engine variants share identical service interval structures for their rear differentials, with a check interval of every 10,000 km or 8 months and a full fluid change interval of every 30,000 km or 24 months under normal use conditions.
- A first-change-only interval is specified for both variants, requiring a fluid change at just 3,000 km or 3 months. A break-in change at such an early mileage is associated with flushing out metal particles and manufacturing residues that accumulate in a new differential during initial operation.
- The 1.95-2.05 liter capacity range of the M3 2.0 rear differential represents a tolerance band of 0.10 liters, which is consistent with the 0.10-liter tolerance band also seen in the 1.6 variant. Both ranges indicate a service fill specification rather than a dry-fill or overhaul figure, as overhaul capacities are typically stated as a single precise value.
- The first-change-only interval of 3,000 km or 3 months applies to both engine variants with the same capacity ranges as their normal-use rows, confirming that the early drain does not alter the refill volume.
