BYD Yuan, S1

Manual transmission fluid capacity & service interval

BYD Yuan and S1 manual transmission fluid capacity ranges from 1,6 to 2,1 liters. Service intervals occur every 30000 km or 48 months. The data covers 2 configurations.

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

Yuan 1.5T (2016-2019)
  • Use: Normal
  • Capacity 2,1 liter
  • Change 30000 km/ 48 months
  • Code: 6T25 6/1

Additional Notes

  • The BYD Yuan 1.5 carries a manual transaxle fluid capacity of 1.6 liters, while the 1.5T variant requires a noticeably larger 2.1 liters, a difference of 0.5 liters that reflects the greater internal volume of the turbocharged engine's associated transaxle assembly.
  • Both the 1.5 and 1.5T transaxle fluid capacities represent service fill figures, meaning the volume needed when draining and refilling during a routine fluid change rather than a full overhaul, which would typically require additional fluid to account for residual passages and components.
  • The change interval for both configurations is set at 30,000 km or 48 months under normal use conditions, meaning the interval applies to standard driving environments rather than demanding or high-stress operating situations.
  • The 48-month time limit on the fluid change interval means that even with low annual mileage, the fluid is due for replacement after four years regardless of distance accumulated.
  • Both the Yuan 1.5 and 1.5T share an identical service interval of 30,000 km or 48 months despite their differing fluid capacities, indicating the interval is not influenced by the volume of fluid held in the transaxle.
