Lincoln MKS

Differential fluid capacity & service interval

Lincoln MKS uses differential fluid with a capacity of 1,15 liters. Service intervals include changes at 100000 miles and 150000 miles. The data covers 8 configurations.

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

Additional Notes

  • The rear differential capacity of 1.15 liters applies uniformly across all listed Lincoln MKS configurations, covering both the 3.5 V6 EcoBoost and the 3.7 V6 AWD variants throughout the 2008-2016 span.
  • A 1.15-liter figure for a rear differential is a relatively modest fill volume, consistent with a compact integrated rear differential unit rather than a larger separate axle housing, and reflects a service-level refill rather than a full overhaul quantity.
  • For the 3.5 V6 EcoBoost in the 2008-2011 and 2012-2013 model years, the rear differential fluid change interval under normal use conditions is set at 150,000 miles.
  • The 3.7 V6 AWD in the 2009-2011 and 2012-2013 model years carries the same 150,000-mile change interval under normal use, matching the EcoBoost specification for those periods.
  • Starting with the 2013-2016 model years, the specifications introduce a severe use condition for both the 3.5 V6 EcoBoost and the 3.7 V6 AWD, with a rear differential fluid change interval of 100,000 miles under those conditions.
  • Severe use conditions typically involve factors such as trailer towing, frequent off-road operation, or repeated stop-and-go driving in extreme temperatures, all of which accelerate fluid degradation and justify the shorter 100,000-mile interval.
  • The 2013-2016 normal use rows for both the 3.5 V6 EcoBoost and the 3.7 V6 AWD list only a capacity value of 1.15 liters without a corresponding change interval, while the severe use rows for the same years and engines do carry the 100,000-mile interval.
  • The capacity value of 1.15 liters remains unchanged across all use conditions and model year groups, indicating the physical fill volume of the rear differential is not affected by whether the vehicle operates under normal or severe conditions.
