Lincoln MKZ

Additional Notes

• The Lincoln MKZ 3.5 V6 configurations from 2007-2009 carry a transaxle automatic fluid capacity of 7 liters, the lowest figure across all engine variants in these specifications. A capacity at this level is typical of a service fill rather than a full overhaul quantity, meaning the figure reflects the amount needed when fluid is drained and refilled without a complete disassembly of the unit.
• Starting with the 2010-2011 model years, the 3.5 V6 transaxle capacity is labeled as a dry fill at 7 liters. A dry fill value represents the total fluid volume required when the transmission is completely empty, such as after a rebuild or replacement, and generally exceeds what a standard drain-and-fill service would require.
• The 2007-2009 3.5 V6 specifications include a fluid check interval of every 15,000 miles under normal use conditions, alongside separate change intervals of either 60,000 or 150,000 miles. The presence of a dedicated check interval in these earlier entries is not carried forward into later model year specifications for any configuration.
• For the 2007-2009 3.5 V6 AWD under normal use, the change interval is 150,000 miles, while the severe use interval drops to 30,000 miles. A five-fold reduction of this magnitude reflects how demanding operating conditions, such as frequent towing, stop-and-go traffic, or extreme temperatures, accelerate fluid degradation.
• The 2.0 GTDI and 3.7 V6 Ti-VCT configurations from 2013-2016 each list two distinct capacity values, 8.5 liters and 11 liters, both under the same normal and severe use conditions. The presence of two capacities for the same engine and year range indicates that two different automatic transaxle units were used across the production run of those configurations.
• Across the 2016-2018 period, the 2.0 GTDI, 2.0 GTDI AWD, 3.0 V6 Ti-VCT, and 3.0 V6 Ti-VCT AWD configurations all carry both 8.5-liter and 11-liter dry fill capacities. The 3.0 V6 Ti-VCT entries, however, retain the 11-liter dry fill capacity exclusively from 2018 onward, while the 2.0 GTDI entries consolidate to 8.5 liters from 2018 onward.
• The severe use change interval of 30,000 miles applies uniformly across all configurations that list a severe use condition, regardless of engine type, drivetrain, or model year. Under severe use classifications, fluid is subjected to greater thermal and mechanical stress, which shortens the interval at which the fluid retains adequate lubricating and protective properties.
• The normal use change interval of 150,000 miles is consistent across all configurations in these specifications. At 150,000 miles, the interval falls within the range that manufacturers associate with lifetime or extended-life fluid designations, though the actual fluid longevity depends on operating conditions remaining within normal parameters.
• The 3.0 V6 Ti-VCT and 3.0 V6 Ti-VCT AWD configurations, covering 2016-2020, carry only the 11-liter dry fill capacity from 2018 onward, while the 2016-2018 entries list both 8.5 and 11 liters. The 3.0 V6 Ti-VCT is the only engine variant in these specifications where the larger 11-liter capacity persists as the sole listed value across all subsequent year ranges.
