Additional Notes

  • Across all three variants of the Honda CRX II (ED8, ED9) covered in the 1988-1991 specifications, the manual transaxle initial fill capacity is listed at 1.9 liters, while the service fill capacity is 1.8 liters.
  • The 0.1-liter difference between the initial fill and service fill figures reflects a common pattern in transaxle servicing, where a small residual volume of fluid remains in the unit after a drain, meaning a full refill to factory-new levels is not achieved during routine maintenance.
  • The 1.5, 1.5 HF, and 1.6 Si variants all share identical capacity figures of 1.9 liters initial and 1.8 liters service fill, indicating no capacity variation across engine displacements or trim levels for the manual transaxle in the 1988-1991 range.
  • Under normal use conditions, the 1.5, 1.5 HF, and 1.6 Si trims all carry the same fluid change interval of 30,000 miles or 24 months, whichever comes first.
  • The 1.6 Si specifications include a separate severe use condition interval, set at 12,000 miles or 12 months. Under severe conditions, the change interval is reduced to less than half the normal mileage threshold and half the time threshold.
  • The severe use interval for the 1.6 Si transaxle applies to the same 1.8-liter service fill capacity as the normal use interval, meaning the fluid volume per service remains unchanged regardless of operating condition classification.
