Additional Notes

  • The rear differential service fill capacity across all AWD configurations — both the 3.0T and the 3.5 V6, in both USA and CAN markets — is 1.7 liters, indicating the amount of fluid used during a routine drain-and-fill service rather than a complete unit rebuild.
  • The Acura MDX 3.5 V6 AWD carries an additional overhaul capacity figure of 1.95 liters, which represents the total fluid volume the rear differential housing holds when completely drained and refilled from empty, such as during a full unit removal or rebuild.
  • The 3.0T AWD configurations do not list an overhaul capacity, meaning only the 1.7-liter service fill figure applies to rear differential fluid work on that engine variant.
  • Under severe use conditions, the Canadian-market MDX 3.5 V6 AWD and 3.0T AWD share an identical rear differential fluid change interval of 24,000 km, with a shortened first-change interval of 12,000 km applied specifically under the combined severe and first-change-only condition.
  • The first-change-only interval under severe conditions for the USA-market MDX 3.0T AWD is 7,500 miles, which is exactly half the standard severe-use interval of 15,000 miles, reflecting a break-in service recommendation for new differential fluid.
  • The same halved relationship between first-change and ongoing severe-use intervals applies to the USA-market MDX 3.5 V6 AWD, where the first change under severe conditions falls at 7,500 miles against a recurring severe interval of 15,000 miles.
  • For all listed AWD configurations in both markets, a flexible interval option governed by the on-board maintenance system is available, and under that condition no fixed mileage or kilometer change interval is specified — only the 1.7-liter service fill capacity (and 1.95-liter overhaul capacity where applicable) is listed.
  • The Canadian and USA market specifications differ in unit of measure but align structurally: the 24,000 km severe interval in Canada corresponds to the 15,000-mile severe interval in the USA, and the 12,000 km first-change interval corresponds to the 7,500-mile first-change interval.
