INFINITI G20, P10 / P11 (USA)

Manual transmission fluid capacity & service interval

INFINITI G20, P10 / P11 (USA) models utilize manual transmission fluid with a capacity of 3,6 liters. Service intervals include checking every 24000 km or 12 months, 15000 miles or 12 months, and changing every 30000 miles or 24 months. The data covers 9 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The INFINITI G20 P10 (1991-1996) manual transaxle carries a stated fluid capacity of 3.6 liters, which represents a specific fill volume rather than a level-based check, distinguishing it from the approach used in later P11 configurations.
  • P11 generations covering 1999-2002 do not specify a fixed fill volume for the manual transaxle. Instead, fluid level is expressed as "between min and max," meaning the correct level is determined by reference marks rather than a measured quantity.
  • On the P10 (1991-1996), the service interval under normal use is a check every 24,000 km or 12 months, with distance expressed in metric units rather than the miles-based intervals found on P11 models.
  • For P11 models across 1999-2002, the normal-use interval calls for a fluid level check every 15,000 miles or 12 months. The time component of 12 months remains consistent with the P10 specification, though the distance threshold differs.
  • Under severe use conditions, P11 models from 1999-2002 require a full fluid change every 30,000 miles or 24 months. The distinction between a check under normal use and a change under severe use reflects meaningfully different service actions for the same transaxle.
  • The severe-use change interval of 30,000 miles on P11 models is exactly double the 15,000-mile normal-use check interval, and the 24-month time limit under severe use is likewise double the 12-month normal-use figure.
  • The P11 severe-use specification applies identically across all four model years covered (1999-2002), with no variation in either the mileage threshold or the time-based interval across that span.
