Additional Notes

  • The Innocenti 950 Spider (1961-1962), C Coupé (1966-1968), and S Spider (1963-1969) all share a rear differential fluid capacity of 1 liter, which is consistent with the compact final drive units found in small-displacement Italian sports cars of the era.
  • A 1-liter differential capacity falls on the smaller end of the spectrum for rear-axle housings, reflecting the lightweight construction priorities of the 950 / C / S platform.
  • The 950 Spider carries a change interval of 12500 km under normal use conditions, the longest interval among the three variants listed.
  • The S Spider specifies a change interval of 12000 km under normal use conditions, placing it 500 km shorter than the 950 Spider interval despite sharing the same 1-liter capacity.
  • The C Coupé carries the shortest change interval of the three at 10000 km under normal use conditions, a figure roughly 20 percent more frequent than the 950 Spider interval.
  • All three intervals are expressed in kilometers rather than time-based periods, meaning service is triggered by distance accumulated rather than elapsed calendar time.
