Rover P5

Differential fluid capacity & service interval

Rover P5 differential fluid capacity ranges from 1,75 to 1,8 liters. Service intervals include checking at 5000 km and 8000 km, and changing at 15000 km, 16000 km, and 32000 km. The data covers 4 configurations.

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

Additional Notes

  • The Rover P5 3-Litre MK II carries a rear differential fluid capacity of 1.8 liters, which is the highest capacity figure across all P5 variants listed and stands slightly above the 1.75-liter figure shared by the MK I, MK III, and 3.5-Litre configurations.
  • The 1.75-liter rear differential capacity on the MK I (1959-1962) represents a service fill volume, meaning the amount of fluid required to bring the unit to its normal operating level during routine maintenance rather than a full overhaul rebuild quantity.
  • The MK I and MK II share a 15,000 km change interval under normal use conditions, while the MK III extends the drain interval slightly to 16,000 km, also under normal use.
  • The 3.5-Litre (1967-1973) carries the same 1.75-liter rear differential capacity as the MK I and MK III, yet the change interval is set at 32,000 km under normal use, which is double the MK III figure and more than double the MK I and MK II intervals.
  • The check interval for the MK I and MK II is 5,000 km under normal use conditions, whereas the MK III and 3.5-Litre both specify an 8,000 km check interval, reflecting a shift in the inspection schedule across the model's production span.
  • All four P5 differential fluid specifications are designated for normal use conditions, meaning the listed check and change intervals apply to standard operating environments rather than severe or demanding service cycles.
  • The MK III (1965-1967) retains the 1.75-liter rear differential capacity of the MK I while introducing a longer check interval of 8,000 km compared to the MK I's 5,000 km, indicating a revised maintenance schedule despite an unchanged fluid volume requirement.
