engine oil LINCOLN MKX 2018 Owner's Manual

We recommend Motorcraft® motor oil foryour vehicle. If Motorcraft® oil is notavailable, use motor oils of therecommended viscosity grade that meet APISN requirements and display the APICertification Mark for gasoline engines. Donot use oil labeled with API SN servicecategory unless the label also displays theAPI certification mark.
An oil that displays this symbol conforms tocurrent engine, emission system and fueleconomy performance standards of ILSAC.
Do not use supplemental engine oil additivesbecause they are unnecessary and couldlead to engine damage that may not becovered by your vehicle warranty.
Note:Ford recommends using DOT 4 LowViscosity (LV) High Performance Brake Fluidor equivalent meeting WSS-M6C65-A2. Useof any fluid other than the recommendedfluid may cause degraded brakeperformance and not meet the Fordperformance standards. Keep brake fluidclean and dry. Contamination with dirt,water, petroleum products or other materialsmay result in brake system damage andpossible failure.
Note: Automatic transmissions that requireMERCON® LV transmission fluid should onlyuse MERCON® LV transmission fluid. Theuse of any other fluid may causetransmission damage.
Alternative Engine Oil for Extremely
Cold Climates
To improve engine cold start performance,we recommend that you use the followingalternative engine oil in extremely coldclimates, where the ambient temperaturereaches -22.0°F (-30°C) or below.

Your vehicle is equipped with the IntelligentOil-Life Monitor system, which displays amessage in the information display at theproper oil change interval. This interval maybe up to one year or 10,000 mi (16,000 km).
When the oil change message appears inthe information display, it is time for an oilchange. Make sure you perform the oilchange within two weeks or 500 mi (800 km)of the message appearing. Make sure youreset the Intelligent Oil-Life Monitor aftereach oil change. See Oil Change IndicatorReset (page 315).
If your information display resets prematurelyor becomes inoperative, you should performthe oil change interval at six months or5,000 mi (8,000 km) from your last oilchange. Never exceed one year or 10,000 mi(16,000 km) between oil change intervals.
Your vehicle is very sophisticated and builtwith multiple, complex, performance systems.Every manufacturer develops these systemsusing different specifications andperformance features. That is why it isimportant to rely upon your dealership toproperly diagnose and repair your vehicle.
Ford Motor Company has recommendedmaintenance intervals for various parts andcomponent systems based upon engineeringtesting. Ford Motor Company relies upon thistesting to determine the most appropriatemileage for replacement of oils and fluids toprotect your vehicle at the lowest overall costto you and recommends againstmaintenance schedules that deviate fromthe scheduled maintenance information.
We strongly recommend the use of onlygenuine Ford, Motorcraft or Ford-authorizedre-manufactured replacement partsengineered for your vehicle.
Additives and Chemicals
This owner's manual and the Ford WorkshopManual list the recommended additives andchemicals for your vehicle. We do notrecommend using chemicals or additives notapproved by us as part of your vehicle’snormal maintenance. Please consult yourwarranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normaloperating characteristic and, by itself, doesnot necessarily indicate a concern or that thefluid needs to be changed. However, aqualified expert, such as the factory-trainedtechnicians at your dealership, shouldinspect discolored fluids that also show signsof overheating or foreign materialcontamination immediately.
Make sure to change your vehicle’s oils andfluids at the specified intervals or inconjunction with a repair. Flushing is a viableway to change fluid for many vehiclesub-systems during scheduled maintenance.It is critical that systems are flushed only withnew fluid that is the same as that requiredto fill and operate the system or using aFord-approved flushing chemical.
