Additional Notes
- The Ford Mustang 4.0 (250 ci) rear limited slip differential holds 1.9 liters of fluid, a capacity typical of a service fill rather than a full overhaul quantity, reflecting the volume needed to bring a partially drained unit back to the correct operating level.
- The 1.9-liter capacity applies specifically to the rear limited slip differential configuration of the 250 ci engine variant, meaning standard open differential setups may carry different fill requirements not reflected here.
- The check interval for the rear limited slip differential on the 250 ci model is set at 10,000 km, 6,000 miles, or 6 months under normal use conditions, whichever comes first, indicating a time-based threshold alongside the distance markers.
- The 6-month time interval running alongside the mileage markers means that low-mileage vehicles driven infrequently still reach a service check point within half a year under normal use conditions.
