Additional Notes

  • The Mercury Milan rear differential fluid capacity across the 2.3 16V AWD and 3.0 V6 24V AWD configurations for 2005-2009 is 1.15 liters, reflecting a service fill volume typical of a compact rear differential unit.
  • The 2010-2011 2.5 16V AWD and 3.0 V6 24V AWD variants share the same 1.15-liter rear differential capacity as the earlier 2005-2009 engines, indicating no change in differential hardware between those generation shifts.
  • A rear differential fluid change interval of 150,000 miles under normal use conditions is specified for both the 2.5 16V AWD and the 3.0 V6 24V AWD in 2010-2011, while no change interval appears for the 2005-2009 equivalents.
  • The Mercury Milan 2.5 Hybrid AWD for 2010-2011 carries a rear differential fluid capacity of 1.4 liters, which is notably higher than the 1.15-liter figure shared by all non-hybrid AWD configurations across the full 2005-2011 span.
  • The larger 1.4-liter capacity in the 2.5 Hybrid AWD rear differential suggests a physically distinct unit compared to the conventional AWD differential, as a higher fill volume generally corresponds to a larger or differently designed housing.
  • No fluid change interval is listed for the 2.5 Hybrid AWD rear differential, in contrast to the 150,000-mile interval assigned to the non-hybrid 2010-2011 AWD variants under normal use conditions.
