Additional Notes
- The rear differential capacity for both the Saturn Sky 2.0 16V Turbo and the 2.4 16V is listed at 1–1.2 liters under normal use conditions, indicating a relatively compact rear differential unit consistent with a two-seat roadster platform.
- When the limited slip differential is fitted, the rear differential capacity rises to 1–1.3 liters across both engine variants, reflecting the additional internal components that a limited slip unit requires compared to an open differential.
- The capacity range notation, such as 1–1.2 liters, represents a service fill tolerance rather than a fixed single value, accounting for minor variation in fluid retained after draining during a routine service.
- All four specification rows carry a normal use condition designation, meaning the listed capacities apply to standard operating environments rather than severe-duty or first-fill scenarios.
- The 0.1-liter difference in upper capacity between the standard rear differential (1.2 liters maximum) and the limited slip rear differential (1.3 liters maximum) is consistent across both the 2.0-liter turbocharged and 2.4-liter naturally aspirated configurations.
