BYD Yuan, S1
Power steering fluid capacity & service interval
BYD Yuan and S1 models utilize power steering fluid with a capacity of 1 liter. Service intervals include checks at 10000 km or 6 months and 12 months, and fluid changes at 20000 km or 12 months, 40000 km or 24 months, and 40000 km. The data covers 3 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The BYD Yuan 1.5 and 1.5T both carry a power steering fluid capacity of 1 liter, which is consistent with a service fill volume rather than a full system overhaul quantity.
- Under normal use conditions, the Yuan 1.5 has a power steering fluid check interval of 10,000 km or 6 months, whichever comes first, making the inspection schedule more frequent than the 1.5T variant.
- The Yuan 1.5 under normal use conditions calls for a fluid change at 20,000 km or 12 months, while the 1.5T under the same conditions extends the change interval significantly to 40,000 km or 24 months.
- The 1.5T check interval is defined solely by a 12-month time threshold under normal use, with no accompanying distance figure, unlike the 1.5 which pairs a distance and time value for the same service point.
- The Yuan 1.5T carries a separate initial service entry, specifying a fluid change at 40,000 km without a time-based counterpart, distinguishing the first scheduled change from the recurring normal-use interval.
- The 1.5T initial service change interval of 40,000 km matches the distance component of the normal-use change interval, meaning the distance threshold remains consistent across both service classifications for that engine variant.
