Additional Notes

  • The Mercedes-Benz SLK-Class R172 (EU) manual transmission fluid capacities vary across engine variants, with values of 1.2, 1.5, and 1.8 liters represented in the specifications.
  • The SLK 200 (172.448) carries the smallest manual transmission fluid capacity in the lineup at 1.2 liters, which is consistent with a compact gearbox unit paired to a lower-displacement petrol engine.
  • The SLK 250 (172.447) sits at an intermediate capacity of 1.5 liters for its manual transmission, placing it between the SLK 200 and the diesel-engined variants in terms of fluid volume.
  • The SLK 250 BlueTEC (172.404), SLK 250 CDI DPF (172.403), and SLK 250 CDI (172.403) all share a manual transmission fluid capacity of 1.8 liters, the highest figure across all listed configurations.
  • The 1.8-liter capacity associated with the diesel variants suggests a physically larger or differently specified gearbox compared to the petrol-engined SLK 200 and SLK 250 units.
  • All manual transmission fluid specifications across the listed variants are designated for normal use conditions, meaning no separate severe-duty or extended-interval figures are present in the data.
  • The SLK 250 CDI DPF (172.403) and SLK 250 CDI (172.403) share the same internal code and an identical 1.8-liter capacity, with the DPF designation indicating the presence of a diesel particulate filter rather than a difference in transmission specification.
  • The SLK 250 BlueTEC (172.404) entered the specification range from 2014, making it the latest-introduced variant among the listed configurations, while still sharing the 1.8-liter transmission capacity with the earlier CDI models.
