Additional Notes

  • Across all AP1 and AP2 configurations, the Honda S2000 AP rear differential holds 0.77 liter as a dry fill capacity, which represents the total volume needed when filling a completely drained or rebuilt unit from scratch.
  • The service fill capacity of 0.74 liter is consistently specified across all configurations, reflecting the slightly lesser volume required during a routine fluid change where residual fluid remains in the housing.
  • The 0.03-liter difference between dry fill and service fill values is a small but deliberate distinction, indicating that a fully disassembled differential requires marginally more fluid than a standard drain-and-refill procedure.
  • For the USA-market AP1 covering 1999-2003, two separate change intervals are specified depending on use condition: normal use calls for a change at 30,000 miles or 24 months, while severe use reduces that interval to 15,000 miles or 12 months.
  • The Canadian-market AP1 for 1999-2003 carries only a single change interval of 15,000 miles or 12 months under normal use, which matches the severe-use interval applied to the USA-market AP1 of the same generation.
  • On the AP2 covering 2003-2009, the severe-use interval is expressed as 15,000 km rather than miles, a unit distinction that sets the AP2 severe-use interval apart from the mile-based figures used across all AP1 entries.
  • The AP2 flexible-interval configuration, governed by an on-board maintenance system, carries capacity values of 0.77 liter dry fill and 0.74 liter service fill but lists no fixed mileage or time-based change interval, as the maintenance system determines service timing dynamically.
