2023 LINCOLN NAVIGATOR fuel

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
