Peugeot 504

Differential fluid capacity & service interval

Peugeot 504 differential fluid capacity ranges from 1,2 to 1,6 liters. Service intervals include checking at 5000 km and changing at 15000 km. The data covers 4 configurations.

Additional Notes

  • The Peugeot 504 rear differential holds 1.2 liters of fluid across both the standard petrol and Diesel variants, a figure consistent with a service fill for a compact rear axle unit.
  • The 504GL and 504Ti trims carry a notably larger rear differential capacity of 1.6 liters, indicating a physically different axle assembly compared to the base and Diesel configurations.
  • All four configurations share an identical check interval of every 5,000 km under normal use conditions, applied uniformly regardless of engine type or trim level.
  • The fluid change interval is set at 15,000 km across all listed configurations, meaning the check-to-change ratio is 3:1 in each case.
  • The 504 Diesel, introduced from 1971, carries the same 1.2-liter rear differential capacity as the original 1968 petrol 504, suggesting no axle modification was made to accommodate the diesel drivetrain.
  • Both the 504GL and 504Ti, also introduced from 1971, share the 1.6-liter capacity, pointing to a common rear axle specification between those two higher-specification trim variants.
