Additional Notes

  • The rear differential capacity across most Fiat 1300/1500/1600S configurations falls into one of two groups: 0.9 liter for the standard and coupe/cabriolet variants, and a noticeably smaller fill for the performance-oriented S models.
  • The Fiat 1500S Cabriolet, 118S (1959-1963) carries the smallest rear differential capacity in the lineup at 0.61 liter, paired with the shortest change interval of 20000 km under normal use conditions.
  • The 1600S Coupe/Cabriolet, 118SA/SB (1963-1966) holds 0.65 liter in the rear differential, a figure slightly above the 1500S Cabriolet but still well below the 0.9 liter seen in the 1300 and 1500 configurations.
  • The 1300, 116 (1961-1967) and the 1500, 115 (1961-1967) share identical rear differential specifications: 0.9 liter capacity, a check interval of 10000 km, and a fluid change interval of 30000 km under normal use.
  • The 1500 Coupe/Cabriolet, 118H/K (1963-1966) also holds 0.9 liter in the rear differential, yet unlike the standard 1300 and 1500 variants, a fluid level check is specified at every 5000 km rather than 10000 km, while the 30000 km change interval remains the same.
  • The more frequent 5000 km check interval assigned to the 1500 Coupe/Cabriolet and both S-model variants, compared to the 10000 km interval on the standard 1300 and 1500, reflects a tighter monitoring schedule tied to those specific configurations under normal use conditions.
  • The 1500S Cabriolet, 118S stands apart from all other configurations by combining the smallest capacity with the only 20000 km change interval, while every other variant in the group is specified at 30000 km for a fluid change under normal use.
