Subaru Mini Jumbo / Rex (EU)
Manual transmission fluid capacity & service interval
Subaru Mini Jumbo / Rex (EU) manual transmission fluid capacity ranges from 1,7 to 2,1 liters. Service intervals include checking at 20000 km or 25000 km/12 months and changing at 40000 km/24 months or 50000 km/24 months. The data covers 2 configurations.

Additional Notes
- The M70 engine variant, covering 1981-1989, carries a manual transaxle fluid capacity of 1.7 liters, while the M80 variant, covering 1989-1992, holds 2.1 liters, representing a difference of 0.4 liters between the two generations.
- A transaxle combines the transmission and drive axle into a single integrated unit, which is why a single fluid capacity figure applies to both gear and differential functions in the Subaru Mini Jumbo / Rex.
- The M70 transaxle fluid change interval is set at 40,000 km or 24 months under normal use conditions, whichever comes first.
- The M80 transaxle extends the fluid change interval to 50,000 km or 24 months under normal use conditions, 10,000 km longer than the M70 specification.
- The M70 specifies a fluid level check at every 20,000 km, meaning two checks fall within each 40,000 km change cycle.
- The M80 fluid level check interval is 25,000 km or 12 months, introducing a time-based threshold not present in the M70 check specification, and resulting in two checks per change cycle when measured by distance.
- Both variants share the same 24-month maximum time limit for fluid changes, indicating a consistent calendar-based boundary across the two engine generations regardless of the differing distance intervals.
