MG Montego
Manual transmission fluid capacity & service interval
MG Montego manual transmission fluid capacity is 2 liters. Service intervals occur every 20000 km or 12 months. The data covers 3 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- All three configurations of the MG Montego covered in these specifications share an identical manual transaxle fluid capacity of 2 liters, indicating a consistent gearbox unit across the 2.0 EFi, 2.0 Turbo, and 2.0i variants.
- A 2-liter transaxle capacity is a relatively modest fill volume, consistent with a compact front-wheel-drive transaxle where the gearbox and differential share a common fluid sump.
- The check interval for all three configurations is set at 20,000 km or 12 months under normal use conditions, whichever comes first, meaning time elapsed is as much a trigger as distance traveled.
- The Montego 2.0i covers model years 1984-1986, while both the 2.0 EFi and 2.0 Turbo span 1986-1989, placing the 2.0i as the earlier variant within the overall 1984-1989 production window reflected in these specifications.
- Despite the performance difference between the naturally aspirated 2.0 EFi and the forced-induction 2.0 Turbo, both share the same 2-liter transaxle capacity and 20,000 km check interval under normal use, suggesting no differentiated service requirement between the two in these specifications.
- The service entries are classified as check intervals rather than drain-and-fill intervals, meaning the specified 20,000 km or 12-month schedule is tied to a fluid level inspection rather than a full fluid replacement for normal use conditions.
