Holder P series

Differential fluid capacity & service interval

Holder P series differential fluid capacity is 14 liters. Service intervals include checking at 150 hours and changing at 1500 hours. The data covers 5 configurations.

Additional Notes

  • Across all five configurations of the Holder P series covered here, the rear differential capacity is 14 liters, a figure consistent with a service fill rather than a full overhaul or dry-fill volume.
  • The check interval for rear differential fluid across every listed P series configuration is 150 hours, applying under normal use conditions.
  • The change interval is 1500 hours under normal use conditions for all listed configurations, meaning a fluid change is due after ten check cycles have elapsed.
  • The P 30 appears in two overlapping year ranges, 1984-1990 and 1990-1991, both sharing identical capacity and interval specifications of 14 liters, 150-hour checks, and 1500-hour changes.
  • The P 70 similarly spans two configurations by year range, 1984-1990 and from 1990 onward, with no variation in rear differential capacity or service intervals between the two.
  • The P 70 A 4WD variant introduced from 1990 onward carries the same 14-liter rear differential capacity and the same 150-hour check and 1500-hour change intervals as the two-wheel-drive P 70 configurations, despite the addition of four-wheel drive.
