2018 LINCOLN MKX oil viscosity

•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.
Noise Emissions Warranty, ProhibitedTampering Acts and Maintenance
On January 1, 1978, Federal regulationbecame effective governing the noiseemission on trucks over 10,000 lb (4,536 kg)Gross Vehicle Weight Rating (GVWR). Thepreceding statements concerning prohibitedtampering acts and maintenance, and thenoise warranty found in the Warranty Guide,are applicable to complete chassis cabs over10,000 lb (4,536 kg) GVWR.
CATALYTIC CONVERTER
WARNINGS
Do not park, idle or drive your vehicleon dry grass or other dry ground cover.The emission system heats up the enginecompartment and exhaust system, creatingthe risk of fire.
The normal operating temperature ofthe exhaust system is very high. Neverwork around or attempt to repair any part ofthe exhaust system until it has cooled. Usespecial care when working around thecatalytic converter. The catalytic converterheats up to a very high temperature afteronly a short period of engine operation andstays hot after the engine is switched off.
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. If you smellexhaust fumes inside your vehicle, have yourvehicle inspected immediately. Do not driveif you smell exhaust fumes.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicable exhaustemission standards.
To make sure that the catalytic converter andother emission control components continueto work properly:
•Do not crank the engine for more than10 seconds at a time.
•Do not run the engine with a spark pluglead disconnected.
•Do not push-start or tow-start yourvehicle. Use booster cables. See JumpStarting the Vehicle (page 276).
•Use only the specified fuel listed.
•Do not switch the ignition off when yourvehicle is moving.
•Avoid running out of fuel.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
Note:Resulting component damage maynot be covered by the vehicle Warranty.

Capacities and Specifications

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.
