Additional Notes

  • The Maserati Mexico AM 112 rear differential holds 1.4 liters of fluid across all listed configurations, covering both the 4200 and 4700 engine variants as well as both standard and limited slip differential types.
  • The 1.4-liter fill capacity applies equally to the standard rear differential and the limited slip rear differential, meaning the limited slip unit does not require a different fluid volume at service time.
  • Under normal use conditions, a fluid level check is specified at every 10,000 km interval, while a full fluid change is called for at every 20,000 km across all six configurations.
  • The Mexico 4700, AM 112/1 appears in two separate production spans, 1964-1967 and 1968-1972, both sharing identical differential fluid capacity and service interval specifications of 1.4 liters, 10,000 km checks, and 20,000 km changes.
  • The Mexico 4200, AM 112 covers the 1969-1972 period and carries the same 1.4-liter differential capacity and 20,000 km change interval as the 4700 variant, despite the difference in engine displacement between the two models.
  • The 20,000 km drain interval means the differential fluid is renewed roughly twice for every 40,000 km of normal operation, reflecting a moderately frequent service cadence for a rear-wheel-drive grand touring vehicle of the era.
