Triumph Dolomite

Differential fluid capacity & service interval

Triumph Dolomite differential fluid capacity ranges from 0,85 to 1,15 liters. Service intervals include checks every 10000 km. The data covers 4 configurations.

Additional Notes

  • The Triumph Dolomite 1300, 1500, and 1850 variants all share a rear differential fluid capacity of 0.85 liter, indicating a compact unit consistent with the smaller-displacement, lighter-duty drivetrain configurations found in those models.
  • The Dolomite Sprint carries a notably larger rear differential capacity of 1.15 liters, which reflects a physically larger or more robustly specified differential unit suited to the higher-output engine in that variant.
  • The 0.30-liter difference between the Sprint's 1.15-liter capacity and the 0.85-liter capacity shared by the other three variants represents a meaningful proportional increase, pointing to a distinct rear axle assembly rather than a shared unit with minor modifications.
  • All four variants specify a check interval of 10,000 km under normal use conditions, meaning the interval applies to standard operating environments rather than demanding or high-stress driving situations.
  • The Dolomite 1850 has the longest production span in the specifications, covering 1971-1980, while the 1300 and 1500 variants appear only from 1976-1980, and the Sprint from 1973-1980.
  • A check interval rather than a change interval is specified across all four variants, meaning the service action at 10,000 km is a fluid level inspection rather than a scheduled drain and refill.
