Vauxhall Cavalier

Differential fluid capacity & service interval

Vauxhall Cavalier differential fluid capacity ranges from 0,65 to 1,1 liters. Service intervals require checks every 10000 km or 6 months. The data covers 4 configurations.

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

Additional Notes

  • The Vauxhall Cavalier Mk I 1.3 rear differential carries a capacity of 0.65 liter, which is notably smaller than the 1.1 liter figure shared by the other engine variants in the same generation.
  • The 1.1 liter rear differential capacity applies to the 1.6, 1.9, and 2.0 engine variants of the Cavalier Mk I, indicating a common differential unit across those three configurations despite their differing engine displacements.
  • A check interval of 10,000 km or 6 months under normal use conditions is specified for the 1.6, 1.9, and 2.0 variants, meaning fluid level verification was expected on a relatively frequent basis by modern standards.
  • The 1.3 variant carries no check interval in the specifications, whereas the 1.6, 1.9, and 2.0 variants each carry the 10,000 km or 6-month check schedule.
  • The 1.9 engine variant spans 1975-1977, making the production window shorter than the 1.6 and 2.0 variants, both of which align with the full 1975-1981 Mk I range or a portion of it.
  • The 2.0 variant covers 1977-1981, meaning the rear differential specification of 1.1 liter with a 10,000 km or 6-month check interval applies only from the midpoint of the Mk I generation onward for that engine.
  • All four configurations are designated as rear differential entries, confirming a rear-wheel-drive layout across the entire Cavalier Mk I lineup represented in the specifications.
  • All rows carry a normal use condition, meaning the stated capacities and check intervals are not adjusted for severe operating conditions in the available specifications.
