Peugeot 404

Differential fluid capacity & service interval

Peugeot 404 differential fluid capacity is 1,4 liters. Service intervals include checking at 3000 km or 5000 km and changing at 6000 km or 10000 km. The data covers 3 configurations.

Additional Notes

  • The Peugeot 404's rear differential holds 1.4 liters of fluid across all three variants listed — the standard petrol, the Diesel, and the Injection.
  • The standard 404 (1961-1975) and the 404 Diesel (1966-1975) share identical service intervals under normal use conditions, with a fluid level check every 3,000 km and a full fluid change every 6,000 km.
  • The 404 Injection (1962-1975) carries the same 1.4-liter rear differential capacity as the other variants, yet I note a notably longer service interval — a check at 5,000 km and a change at 10,000 km under normal use conditions.
  • The 6,000 km change interval on the standard and Diesel variants is relatively short by general automotive standards, reflecting the maintenance philosophy common to vehicles of that era.
  • All three variants specify normal use conditions, meaning the intervals listed apply to typical driving rather than severe or demanding operating environments.
