Hudson Commodore

Clutch fluid capacity & service interval

Hudson Commodore uses clutch fluid with a capacity of 0,16 liter. Service intervals require a change every 5000 miles. The data covers 6 configurations.

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

Additional Notes

  • The Hudson Commodore clutch fluid capacity of 0.16 liter applies to a hydraulic clutch system, which uses fluid pressure rather than a mechanical linkage to disengage the clutch. A capacity this small is typical of a sealed hydraulic actuator circuit, as opposed to a larger reservoir-fed system.
  • The 0.16 liter figure represents a service fill volume for the hydraulic clutch circuit. Values this low are characteristic of a compact master cylinder and slave cylinder arrangement, where the total fluid volume in the lines and chambers is minimal by design.
  • The 5,000-mile change interval under normal use conditions applies uniformly across both the Six and Eight engine variants for all listed model year ranges. Normal use conditions generally describe everyday driving without sustained heavy loads, extreme temperatures, or repeated short-trip operation.
  • Both the Commodore Six and Commodore Eight share identical clutch fluid capacity and change interval specifications across all listed configurations. The hydraulic clutch system design did not differ between the six-cylinder and eight-cylinder variants in terms of fluid volume or service frequency.
  • The 1951-1952 model year range overlaps with the 1948-1951 range for both the Six and Eight variants. The 1951 model year therefore appears in two separate specification rows for each engine type, reflecting a transitional period in the production sequence.
  • A 5,000-mile fluid change interval for a hydraulic clutch system is relatively short by modern standards, consistent with mid-twentieth century fluid formulations that were more susceptible to moisture absorption and degradation over time.
