oil LINCOLN NAVIGATOR 2023 Owner's Manual

If your instrument cluster display resetsprematurely or becomes inoperative, youshould perform the oil change interval at sixmonths or 5,000 mi (8,000 km) from yourlast oil change. Never exceed one year or10,000 mi (16,000 km) between oil changeintervals.
You can drive your vehicle in such a way thatmay lead to higher oil consumption includingextended time at high engine speeds, highloads, engine braking, hard corneringmaneuvers, track and off-road usage. Underthese conditions, oil consumption ofapproximately 1 quart per 500 miles (1 literper 800 km) is possible. Check the engineoil level at every refueling and adjust tomaintain proper levels to avoid enginedamage.
You can also drive your vehicle in such a waythat dilutes and increases the level of oil byfrequent short trips that do not allow theengine to get to operating temperature,extended idling and low speed driving forlong periods of time.
It is important to rely upon your dealershipto properly diagnose and repair your vehicle.
We strongly recommend only using ourgenuine or our authorized re-manufacturedreplacement parts engineered for yourvehicle.
Additives and Chemicals
We do not recommend using chemicals oradditives not approved by us as part of yourvehicle’s normal maintenance. Please consultyour warranty 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. Have discoloredfluids that also show signs of overheating orforeign material contamination checkedimmediately.
Make sure to change the 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 ourapproved flushing chemical.

Tampering With a Noise ControlSystem
Federal laws prohibit the following acts:
•Removal or rendering inoperative by anyperson other than for purposes ofmaintenance.
•Repair or replacement of any device orelement of the design incorporated intoa new vehicle for the purpose of noisecontrol prior to its sale or delivery to theultimate purchaser or while it is in use.
•The use of the vehicle after any personremoves or renders inoperative anydevice or element of the design.
The U.S. Environmental Protection Agencymay presume to constitute tampering asfollows:
•Removal of hood blanket, fender apronabsorbers, fender apron barriers,underbody noise shields or acousticallyabsorptive material.
•Tampering or rendering inoperative theengine speed governor, to allow enginespeed to exceed manufacturerspecifications.
If the engine does not start, runs rough,experiences a decrease in engineperformance, experiences excess fuelconsumption or produces excessive exhaustsmoke, check for the following:
•A plugged or disconnected air inletsystem hose.
•A plugged engine air filter element.
•Water in the fuel filter and waterseparator.
•A clogged fuel filter.
•Contaminated fuel.
•Air in the fuel system, due to looseconnections.
•An open or pinched sensor hose.
•Incorrect engine oil level.
•Incorrect fuel for climatic conditions.
•Incorrect engine oil viscosity for climacticconditions.
Note:Some vehicles have a lifetime fuel filterthat is integrated with the fuel tank. Regularmaintenance or replacement is not needed.
Note:If these checks do not help you correctthe concern, have your vehicle checked assoon as possible.
