Ford Taunus 20M (EU)

Differential fluid capacity & service interval

Ford Taunus 20M (EU) differential fluid capacity is 1,1 liter. Service intervals include checking at 5000 km and changing at 20000 km. The data covers 6 configurations.

Additional Notes

  • All six configurations of the Ford Taunus 20M (EU) share an identical rear differential fluid capacity of 1.1 liters, spanning both the P5 and P7b body generations across the full 1964-1971 production range.
  • A 1.1-liter capacity is characteristic of a compact rear differential unit, typical of European family saloons from this era, where the drivetrain was sized for modest engine outputs rather than heavy-duty use.
  • The P5 generation (1964-1967) carries explicit service interval data: a fluid level check every 5,000 km and a full fluid change every 20,000 km, both under normal use conditions.
  • A 5,000 km check interval on the P5 differential reflects the shorter service schedules common to 1960s vehicles, where lubricant quality and sealing technology required more frequent inspection than later designs.
  • The 20,000 km change interval on the P5 applies to normal use conditions, meaning the interval was defined for standard road driving rather than severe or demanding operating environments.
  • The P7b generation (1968-1971) lists only the 1.1-liter capacity figure for all four of its configurations, with no check or change interval data present in the specifications for those rows.
  • The Ford Taunus 20M (EU) P7b generation covers three distinct engine variants in the differential specifications: the 2.0-liter HC, the 2.0-liter LC, and the 2.6-liter, yet all three share the same 1.1-liter differential capacity.
  • The HC and LC designations on the 2.0-liter engine refer to high compression and low compression tuning respectively, representing different power outputs within the same displacement, yet neither variant alters the rear differential fluid requirement.
  • The Taunus 20M RS (2.6 ltr.) P7b is a sportier trim level distinguished from the standard 2.6-liter P7b in name, but the rear differential capacity of 1.1 liters is identical between the two configurations.
