TVR S3, S3C
Differential fluid capacity & service interval
TVR S3 and S3C models require 1,4 liters of differential fluid. Service intervals occur every 10000 km or 6 months. The data covers 1 configuration.

Additional Notes
- The rear differential on the TVR S3 and S3C carries a fluid capacity of 1.4 liters, which is consistent with a service fill volume rather than a full overhaul quantity, meaning the housing is partially filled to the correct operating level rather than drained and refilled to a larger total internal volume.
- The 1.4-liter capacity figure applies uniformly across the S3 and S3C variants produced from 1989-1994, with no differentiation recorded between the two body or mechanical configurations for this particular system.
- The specified check interval is 10,000 km or 6 months, whichever comes first, and both thresholds are tied to normal use conditions, meaning the interval assumes standard driving demands rather than elevated stress or load cycles.
- A 6-month time-based interval running alongside the 10,000 km distance threshold reflects that differential fluid can degrade through moisture absorption and thermal cycling even when mileage accumulation is low, making calendar time a relevant trigger independent of distance traveled.
