MG MG-ZR

Manual transmission fluid capacity & service interval

MG MG-ZR manual transmission fluid capacity ranges from 1,8 to 2 liters. Service intervals include checks at 20000 to 25000 km or 12 months and changes at 175000 to 180000 km or 84 months. The data covers 6 configurations.

Additional Notes

  • Across the MG ZR 2001-2005 range, manual transaxle fluid capacity splits into two values depending on engine displacement. The 1.4 and 1.6 16V variants share a 1.8-liter fill capacity, while the 1.8 16V, 1.8 16V VVC, and TD variants each require 2 liters. The 0.2-liter difference reflects the larger transaxle housings paired with higher-displacement and higher-torque drivetrains.
  • The 1.4 16V, 1.4 Plus, and 1.6 16V all carry identical specifications: a 1.8-liter capacity, a check interval of 25,000 km or 12 months, and a fluid change interval of 175,000 km or 84 months under normal use conditions. The alignment across these three variants indicates a shared transaxle unit.
  • The MG ZR 1.8 16V and 1.8 16V VVC share the same 2-liter capacity and a check interval of 25,000 km or 12 months under normal use. Neither variant carries a listed change interval in the specifications, distinguishing them from the other configurations in the lineup.
  • The VVC designation on the 1.8 16V refers to Variable Valve Control, a technology that varies intake valve timing to improve power output across the rev range. Despite the mechanical distinction from the standard 1.8 16V, both share identical transaxle fluid specifications.
  • The MG ZR TD is the only diesel variant in the specifications and carries a 2-liter transaxle capacity. Under normal use, fluid checks are scheduled at 20,000 km or 12 months, a shorter distance interval than the 25,000 km interval applied to all petrol variants.
  • The TD variant also carries a fluid change interval of 180,000 km with no month-based limit stated alongside it, unlike the 1.4 and 1.6 petrol variants whose 175,000 km change interval is paired with an 84-month ceiling. The TD change interval is therefore expressed as a distance-only threshold.
  • The 84-month change interval on the 1.4 and 1.6 petrol variants equals seven years. At the paired 175,000 km distance threshold, whichever limit is reached first under normal use conditions would typically govern the service action in standard maintenance practice.
