Additional Notes

  • The Mercedes-Benz SLC-Class R172 (EU) manual transmission fluid capacity falls into two distinct values across the lineup: 1.2 liters for most variants and 1.8 liters for one specific configuration.
  • The SLC 180 (172.431), SLC 200 (172.434), and SLC 250 (172.435) all share an identical manual transmission fluid capacity of 1.2 liters under normal use conditions.
  • The SLC 250 d (172.404) carries a notably higher manual transmission fluid capacity of 1.8 liters under normal use conditions, which is 50% more than the 1.2-liter figure seen across the petrol variants.
  • A capacity of 1.2 liters is a relatively modest fill volume, consistent with compact manual gearboxes typically found in smaller-displacement passenger cars.
  • The 1.8-liter capacity of the SLC 250 d (172.404) reflects a physically larger or differently engineered gearbox, as diesel engines often pair with transmissions designed to handle higher torque loads.
  • All four configurations specify normal use conditions, meaning the stated capacities and service intervals apply to standard driving rather than severe or demanding operational cycles.
  • The SLC 180 (172.431) covers the 2016-2020 model years, making it the only variant in the lineup with a starting year of 2016 rather than 2015.
  • The SLC 250 d (172.404) has the narrowest production window among the listed variants, spanning only 2015-2017, compared to the 2015-2020 range of the other three configurations.
