Tatra 815

Power steering fluid capacity & service interval

Tatra 815 requires power steering fluid with a capacity of 4,5 liters. Service intervals occur every 90000 km or 12 months. The data covers 3 configurations.

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

Additional Notes

  • The Tatra 815 T 815-2 260S25 TERRNo.1 variants — spanning the 3B-928-10, 3B-928-50, and 3B-928-60 configurations — all carry a power steering fluid capacity of 4.5 liters, which is consistent with a full system service fill rather than a partial top-up volume.
  • A 4.5-liter capacity in a power steering system reflects a relatively large reservoir and circuit volume, typical of heavy-duty commercial or off-road vehicles where the steering assist demands are significantly higher than in passenger cars.
  • The service interval for power steering fluid across all three listed configurations is set at 90,000 km or 12 months, whichever comes first, under normal use conditions.
  • The dual-condition interval structure — combining a distance threshold of 90,000 km with a fixed 12-month calendar limit — means that low-mileage operation does not extend the fluid's service life beyond one year.
  • All three configurations share identical capacity and interval specifications, indicating no variation in power steering system requirements across the 3B-928-10, 3B-928-50, and 3B-928-60 body or chassis variants within the T 815-2 260S25 TERRNo.1 range starting from 1996.
