BYD Su Rui

Automatic transmission fluid capacity & service interval

BYD Su Rui automatic transmission fluid capacity is 1,8 liters. The service interval is 60000 km. The data covers 2 configurations.

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

Additional Notes

  • Both configurations share an identical automatic transmission fluid capacity of 1.8 liters, which is consistent with a transaxle-integrated semi-automatic DCT unit where the fluid volume is relatively compact compared to conventional torque-converter automatic transmissions.
  • The BYD Su Rui 113 kW variant, covering 2012-2015, carries a service interval of 60,000 km under normal use conditions for the DCT transaxle fluid.
  • The 80 kW variant, spanning 2012-2018, shares the same 60,000 km normal-use change interval and 1.8-liter capacity as the higher-output 113 kW configuration, indicating no differentiation in fluid service requirements between the two power outputs.
  • A 60,000 km interval under normal use conditions reflects a moderate-duty service schedule, typical for DCT fluid that operates under controlled thermal and mechanical stress in everyday driving scenarios rather than severe or high-load conditions.
  • The designation of the transmission as a semi-automatic DCT transaxle means the fluid serves both the clutch actuation mechanism and the gear set lubrication within a single integrated housing, which is why the 1.8-liter capacity applies to the entire transaxle assembly as one service unit.
