MG MG HS / MG EHS

Automatic transmission fluid capacity & service interval

MG HS / MG EHS requires automatic transmission fluid with a capacity range of 2,15 to 4,4 liters. Service intervals occur every 45000 miles or 36 months. The data covers 6 configurations.

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

Additional Notes

  • The MG EHS 1.5T GDI PHEV (190 kW) carries the largest single transaxle fluid capacity in the lineup at 4.4 liters, which is notably higher than the non-hybrid variants and reflects the added mechanical complexity of a PHEV semi-automatic transaxle.
  • Both PHEV configurations of the MG HS 1.5 GDI rated at 226 kW and 249 kW share an identical 3-liter transaxle capacity, despite the difference in power output between the two variants introduced from 2024.
  • The MG HS 1.5T GDI (124 kW) covering model years 2018-2024 holds 2.45 liters in its semi-automatic transaxle, a figure that reappears in the transmission part of the later 125 kW variant, suggesting a shared transmission housing dimension between the two generations.
  • The 125 kW variant of the MG HS 1.5T GDI introduced from 2024 splits its transaxle fluid into two separate service points: 2.15 liters for the clutch part and 2.45 liters for the transmission part, giving a combined fill requirement that exceeds the single-fill figure of the earlier 124 kW version.
  • A service interval of 45,000 miles or 36 months under normal use conditions applies to the MG EHS 1.5T GDI PHEV (190 kW) and the MG HS 1.5T GDI (124 kW), making the time-based threshold the more likely limiting factor in lower-mileage usage patterns.
  • The split-fill design of the 125 kW transaxle, separating clutch and transmission fluid volumes, indicates a dual-wet-clutch or similar architecture where each fluid circuit serves a mechanically distinct function within the same housing assembly.
