Additional Notes

  • The Lexus GS 300 (USA) rear differential holds 1.35 liters across all model years from 1993-1997, a figure consistent with a service fill rather than a full overhaul capacity.
  • For the 1993-1994 model years, the normal use condition calls for a fluid check at 15,000 miles or 24 months, while severe use at the same interval requires a full fluid change rather than a check.
  • The 1995 model year introduces a notable shift in the normal use time interval, reducing the check interval from 24 months to 12 months while keeping the mileage threshold at 15,000 miles.
  • Under severe use conditions, the 1995 GS 300 retains the 15,000-mile and 24-month change interval seen in 1993-1994, meaning the severe schedule remained unchanged even as the normal schedule was tightened on the time side.
  • The 1993-1995 normal use rows specify a check action rather than a change, indicating the fluid is inspected for condition and level at the stated interval rather than automatically replaced.
  • The 1996-1997 normal use specification lists only the 1.35-liter capacity without an associated interval, distinguishing those model years from the 1993-1995 entries where both capacity and interval data are present.
