Datsun (Nissan) Sunny, B110/B210/B310
Power steering fluid capacity & service interval
Datsun (Nissan) Sunny, B110/B210/B310 models utilize power steering fluid with a capacity range of 0,24 to 0,25 liters. Service intervals include 10000 km/6 months and 20000 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 1000 B10 carries a steering gear capacity of 0.24 liter, which is a relatively small fill volume consistent with a mechanical steering gear box rather than a hydraulic power steering pump circuit.
- Both the 120Y B310 and 140Y B310 share an identical steering gear capacity of 0.25 liter, placing them marginally above the 1000 B10 figure despite spanning a different generation of the Sunny lineup.
- The Datsun (Nissan) Sunny 1000 B10 carries a check interval of 20,000 km under normal use conditions, which is twice the distance specified for the later B310 variants.
- The 120Y and 140Y B310 models both carry a dual-trigger check interval of 10,000 km or 6 months under normal use, meaning whichever threshold arrives first would govern the service timing.
- The addition of a time-based criterion of 6 months alongside the distance interval in the B310 specifications reflects a recognition that calendar aging of fluid can occur independently of mileage accumulation.
- All three configurations are designated for normal use conditions, meaning the stated intervals and capacities apply to standard operating environments without a separate severe-duty specification present in the data.
- The steering gear note applied to all three rows indicates the fluid capacity figures refer to the gear assembly itself, not a remote reservoir or pump, which is characteristic of recirculating ball or worm-and-sector steering designs common to vehicles of that era.
