Tatra 815
Differential fluid capacity & service interval
Tatra 815 differential fluid capacity is 9 liters. Service intervals require a change every 60000 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 Tatra 815 T 815-2 260S25 TERRNo.1 variants 3B-928-10, 3B-928-50, and 3B-928-60 each carry a rear differential fluid capacity of 9 liters, which is consistent with a service fill volume on a heavy-duty axle assembly of this class.
- All three configurations share an identical 60,000 km change interval, applied under normal use conditions, meaning standard operating cycles without the accelerated wear factors that would otherwise trigger a shortened severe-duty schedule.
- The 9-liter rear differential capacity across the 3B-928-10, 3B-928-50, and 3B-928-60 variants indicates no variation in differential housing size among these three builds of the same base configuration.
- A 60,000 km fluid change interval on a rear differential of this capacity reflects a relatively extended drain cycle, typical of heavy commercial vehicle differentials designed for long-haul or demanding terrain applications under normal conditions.
