Peugeot 402

Differential fluid capacity & service interval

Peugeot 402 differential fluid capacity is 2,2 liters. Service intervals include checking at 2000 km and changing at 5000 km. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Peugeot 402 rear differential holds 2.2 liters of fluid, a figure that applies uniformly across both the 402 (1935-1938) and the 402 B (1939-1942) variants.
  • A check interval of 2,000 km is specified for normal use conditions on the 402 rear differential, indicating a relatively frequent monitoring schedule consistent with the mechanical standards of pre-war automotive engineering.
  • The change interval is set at 5,000 km under normal use, meaning a full fluid replacement is due roughly every two and a half check cycles.
  • The 2.2-liter capacity figure represents a service fill level, as no separate overhaul or dry-fill value is listed, suggesting the same volume applies whether topping off or performing a complete drain and refill.
  • The specifications for the 402 B (1939-1942) are identical to those of the earlier 402 in all three measured parameters: capacity, check interval, and change interval, indicating no revision to the rear differential service requirements between the two variants.
