Opel Karl, C16

Manual transmission fluid capacity & service interval

Opel Karl and C16 manual transmission fluid capacity is 1,8 liters. Service intervals include checks every 30000 km or 12 months and changes every 150000 km or 120 months. The data covers 3 configurations.

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

Additional Notes

  • The Opel Karl C16 manual transaxle holds 1.8 liters of fluid across all listed configurations, which is a service fill figure representing the amount needed to bring the unit to the correct operating level during a fluid change or top-up procedure.
  • The 1.0 petrol variant covering 2015-2018 and the revised 1.0 petrol variant covering 2018-2020 share identical fluid capacity and interval specifications, with no differentiation between the two production periods in the provided data.
  • The 1.0 LPG variant from 2016-2018 also carries the same 1.8-liter transaxle capacity and the same check and change intervals as the petrol variants, indicating a uniform transmission specification regardless of fuel system type.
  • Under normal use conditions, the fluid check interval is set at 30,000 km or 12 months, whichever comes first, meaning the transaxle level is inspected on a relatively frequent basis relative to the full change interval.
  • The fluid change interval under normal use is 150,000 km or 120 months (10 years), a long-life schedule that reflects the sealed or semi-sealed nature of modern manual transaxle designs where fluid degradation is considered gradual under standard driving conditions.
  • The gap between the check interval (30,000 km / 12 months) and the change interval (150,000 km / 120 months) is a factor of five in both distance and time, meaning the fluid is inspected multiple times before a full drain and refill is due.
