Renault Frégate (EU)
Differential fluid capacity & service interval
Renault Frégate (EU) differential fluid capacity ranges from 0,8 to 1,5 liters. Service intervals require a change every 5000 km. The data covers 4 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Renault Frégate 2.0 R1100, covering model years 1951-1956, carries a rear differential fluid capacity of 0.8 liter, a relatively modest fill volume consistent with the compact rear axle housings typical of early 1950s passenger cars.
- The Frégate 2.1 R1101/R1102 from 1955-1957 shares the same 0.8 liter rear differential capacity as the earlier R1100, despite representing a displacement increase over the original 2.0-liter engine variant.
- The Frégate/Domaine 2.1 R1103 from 1957-1960 specifies a rear differential capacity of 1.5 liters, nearly double the 0.8 liter figure of the R1101/R1102, indicating a physically larger or redesigned rear axle assembly was introduced with the R1103 generation.
- The Frégate Transfluide R1104, produced from 1958-1960, also carries a 1.5 liter rear differential capacity, placing the automatic-transmission-equipped variant on equal footing with the R1103 in terms of rear axle fluid volume.
- A 5000 km change interval applies uniformly across all four configurations under normal use conditions, meaning no variant within the Frégate range specifies a more or less frequent differential service schedule relative to the others.
- A 5000 km differential fluid change interval was a demanding standard by mid-20th century norms, reflecting the limited oxidation stability and load-carrying performance of gear oils available during the 1950s compared to modern formulations.
