Ford V8 (USA)

Differential fluid capacity & service interval

Ford V8 (USA) requires 1,2 liters of differential fluid. Service intervals include normal use. The data covers 3 configurations.

Additional Notes

  • The Ford V8 (USA) rear differential capacity of 1.2 liters applies uniformly across all three configurations covered in the 1933-1940 period, spanning the Model 18, Model 48, and the general V8 variant.
  • A 1.2-liter rear differential fill is a relatively modest service volume, consistent with the compact axle housings typical of passenger cars from the 1930s rather than the larger capacities associated with truck or heavy-duty axle assemblies.
  • The Ford V8 (model 18) covers the 1933-1935 model years, while the Ford V8 (model 48) covers 1935-1936, meaning 1935 is a year in which both model designations are represented in the specifications.
  • All three configurations carry a normal use condition tied to the 1.2-liter capacity figure, indicating the specification applies to standard operating circumstances rather than severe-duty or first-change-only scenarios.
  • The general V8 variant, covering 1937-1940, represents the latest model years in the dataset and shares the same 1.2-liter rear differential capacity as the earlier model-designated variants.
