Mercury Topaz
Automatic transmission fluid capacity & service interval
Mercury Topaz uses automatic transmission fluid with a capacity range of 8 to 9,6 liters. Service intervals require a change every 35000 km. The data covers 4 configurations.

Additional Notes
- The Mercury Topaz 4WD (1987-1992) carries a notably higher automatic transmission fluid capacity of 9.6 liters compared to the 8-liter figure listed for transaxle-equipped trims, a difference that reflects the mechanical distinction between a traditional rear-wheel-drive-style transmission and a front-wheel-drive transaxle layout.
- The 8-liter automatic transaxle capacity applies uniformly across the GS, LS, XR5, and LTS trims for 1988-1992, as well as the GS and LS through 1994, indicating a shared transaxle unit across those configurations.
- The XR5 and LTS trims from 1988-1992 are the only configurations in the specifications carrying a defined service interval, with a 35,000 km change interval listed exclusively under severe use conditions.
- The severe-use interval of 35,000 km for the XR5 and LTS transaxle applies to the same 8-liter fluid capacity as the normal-use entry for those trims, meaning the fluid volume at service remains constant regardless of use condition.
- No change interval appears under the normal-use entry for the XR5 and LTS trims, while the severe-use row carries the 35,000 km figure, placing the only interval specification in the more demanding operating condition category.
- The GS and LS trims extend through 1994 in the specifications, covering a longer production window than the XR5 and LTS entries, which conclude at 1992.
