Additional Notes

  • Across all listed Saab 900 Cabriolet configurations spanning 1985-1994, the differential fluid capacity is uniformly specified at 1.25 liters. This figure applies to the differential unit sourced from an automatic transmission, as noted across every row in the data.
  • The 1.25-liter capacity is consistent with a compact integrated differential housing, typical of front-wheel-drive transaxle designs where the differential shares a casing with the transmission rather than occupying a separate rear axle unit.
  • The "from automatic" note attached to each configuration indicates the differential unit in question is the variant paired with an automatic gearbox. This distinction is relevant because differential housings derived from different transmission types can carry different fluid volumes.
  • The service interval for all listed configurations is a fluid level check at every 20,000 km or 12 months, whichever comes first, under normal use conditions. A check interval rather than a change interval means the specification calls for verifying fluid level and condition rather than a scheduled full drain and refill.
  • The 900 Turbo 16 Cabriolet appears across two separate year ranges, 1985-1987 and 1987-1993, both sharing the same 1.25-liter capacity and 20,000 km check interval. The split into two entries likely reflects a mid-production specification or variant revision rather than a change in fluid capacity.
  • The 900i 16V 2.1 Cabriolet covers model years 1990-1991, while the 900i 16V Cabriolet spans 1990-1993. Despite the difference in engine displacement designation, both carry identical differential fluid specifications of 1.25 liters with a 20,000 km or 12-month check interval under normal use.
  • The 900i Cabriolet covering 1986-1990 and the 900 S Cabriolet covering 1991-1994 represent the non-turbocharged and higher-trim naturally aspirated variants respectively, yet both share the same differential fluid capacity and service interval as the turbocharged models in the dataset.
