Additional Notes

  • All three configurations listed for the Mercedes-Benz SL-Class R129 share an identical power steering fluid capacity of 1 liter, indicating a uniform reservoir size across the six-cylinder, eight-cylinder, and twelve-cylinder variants covered in the specifications.
  • A 1-liter capacity is characteristic of a service fill figure, representing the amount of fluid held within the power steering reservoir and lines during normal operation rather than a full system overhaul volume.
  • The SL 320 carries a 30,000 km inspection interval under normal use conditions, which is the only scheduled check interval present across all three configurations in the specifications.
  • The SL 500 and SL 600 have no inspection interval listed alongside their 1-liter capacity figures, whereas the SL 320 pairs the same capacity with a 30,000 km check interval under normal use.
  • All three configurations are designated under normal use conditions, meaning the capacity and interval figures apply to standard operating environments rather than severe or demanding service cycles.
