Additional Notes
- The Maserati Quattroporte M139 rear differential carries 1.1 liters of fluid in the base Quattroporte and Quattroporte CENTO configurations, while the GT S, GT S AWARDS, and S variants each hold 1.0 liter.
- A 0.1-liter difference between the base and CENTO trims versus the GT S, GT S AWARDS, and S trims points to a physical distinction in the rear differential units fitted across the M139 lineup.
- The 1.1-liter capacity shared by the base Quattroporte (2008-2013) and the Quattroporte CENTO (2008-2009) indicates a common rear differential assembly between those two variants.
- The Quattroporte GT S (2009-2013), GT S AWARDS (2011-2013), and S (2008-2013) all share the same 1.0-liter rear differential capacity, reflecting a consistent unit across those performance-oriented trims.
- All five configurations across the M139 range share an identical service interval: a fluid check every 20,000 km or 24 months under normal use conditions, whichever comes first.
- The 24-month time-based threshold in the check interval means that even low-mileage vehicles are subject to a fluid inspection within two years, regardless of distance traveled.
- The service specification is expressed as a check rather than a change, meaning the interval defines when the fluid level and condition are to be inspected, not necessarily when a full drain-and-fill is performed.
- All listed intervals are designated for normal use conditions, meaning the 20,000 km / 24-month check schedule applies to standard operating environments rather than severe or track-use scenarios.
