Additional Notes
- The FSO Classic / Caro 1.5 SLE and Estate rear differential holds 1.2 liters of fluid, which is a service fill figure reflecting the working capacity of the differential housing under normal operating conditions.
- A change interval of 30,000 km or 36 months is specified for normal use, meaning whichever of the two thresholds is reached first governs when the fluid is due for replacement.
- The 36-month time limit alongside the 30,000 km distance interval indicates that calendar aging of the fluid is treated as an independent factor, not merely a secondary consideration to mileage accumulation.
