Maserati Ghibli, AM 115

Differential fluid capacity & service interval

Maserati Ghibli, AM 115 uses differential fluid with a capacity of 1,4 liters. Service intervals include checking at 10000 km and changing at 20000 km. The data covers 2 configurations.

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

Additional Notes

  • The Maserati Ghibli AM 115 rear differential holds 1.4 liters of fluid, a figure that reflects a service fill capacity rather than a full overhaul or dry fill, as the housing retains residual fluid during routine changes.
  • Both the standard rear differential and the limited-slip rear differential share an identical 1.4-liter capacity across the 1967-1973 production span, meaning the limited-slip clutch pack assembly does not alter the total fluid volume required.
  • The check interval for both differential configurations is set at 10,000 km under normal use conditions, a relatively short inspection cycle consistent with the maintenance expectations of high-performance European vehicles of the era.
  • The fluid change interval is specified at 20,000 km under normal use conditions, placing the drain-and-refill cycle at exactly double the check interval for both the standard and limited-slip rear differentials.
  • The limited-slip differential carries the same 20,000 km change interval as the open differential despite the additional mechanical demands of a limited-slip unit, where friction modifiers in the fluid are subject to degradation from clutch pack engagement.
