Cadillac CTS(-V) (EU)

Differential fluid capacity & service interval

Cadillac CTS-V (EU) differential fluid capacity is 1,2 liters. Service intervals include 30000 km/24 months, 72000 km, and 80000 km. The data covers 3 configurations.

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

Additional Notes

  • The rear limited slip differential on the Cadillac CTS-V carries a fluid capacity of 1.2 liters across all listed configurations, a figure consistent with a service fill rather than a full overhaul quantity.
  • The 2016-2017 CTS-V 6.2 V8 carries a normal-use differential fluid change interval of 72,000 km, which is notably shorter than the interval assigned to the overlapping 2017-2019 configuration under the same normal-use condition.
  • For the 2017-2019 CTS-V 6.2 V8, the normal-use change interval extends to 80,000 km, representing a longer drain period compared to the earlier 2016-2017 specification for the same engine and differential type.
  • The 2017-2019 CTS-V 6.2 V8 under severe use carries a change interval of 30,000 km or 24 months, whichever comes first, meaning both a distance threshold and a fixed time limit govern fluid replacement under demanding operating conditions.
  • The gap between the severe-use interval of 30,000 km and the normal-use interval of 80,000 km for the 2017-2019 configuration reflects a significant difference in how operating conditions affect the recommended service frequency for the rear limited slip differential fluid.
