fuel additives LINCOLN MKZ 2018 Owners Manual

We recommend regular unleaded gasolinewith a minimum pump (R+M)/2 octane ratingof 87. Some stations offer fuels posted asregular with an octane rating below 87,particularly in high altitude areas. We do notrecommend fuels with an octane ratingbelow 87. To provide improved performance,we recommend premium fuel for severe dutyusage such as trailer tow.
Do not use any fuel other than thoserecommended because they could lead toengine damage that may not be covered bythe vehicle Warranty.
Note:Use of any fuel other than thoserecommended can impair the emissioncontrol system and cause a loss of vehicleperformance.
Do not use:
•Diesel fuel.
•Fuels containing kerosene or paraffin.
•Fuel containing more than 15% ethanolor E85 fuel.
•Fuels containing methanol.
•Fuels containing metallic-based additives,including manganese-based compounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel (using leaded fuel isprohibited by law).
The use of fuels with metallic compoundssuch as methylcyclopentadienyl manganesetricarbonyl (commonly known as MMT), whichis a manganese-based fuel additive, willimpair engine performance and affect theemission control system.
Do not be concerned if the enginesometimes knocks lightly. However, if theengine knocks heavily while using fuel withthe recommended octane rating, contact anauthorized dealer to prevent any enginedamage.
FUEL FILLER FUNNEL LOCATION
The fuel filler funnel is under the luggagecompartment floor covering.RUNNING OUT OF FUEL
Running out of fuel can cause damage notcovered by the vehicle Warranty.

Note:Do not remove the dipstick when theengine is running.
Note: If the oil level is between themaximum and minimum marks, the oil levelis acceptable. Do not add oil.
Note:The oil consumption of new enginesreaches its normal level after approximately3,000 mi (5,000 km).
Adding Engine Oil
WARNING
Do not remove the filler cap when theengine is running.
Do not use supplemental engine oil additivesbecause they are unnecessary and couldlead to engine damage that may not becovered by the vehicle Warranty.
Only use oils certified for gasoline enginesby the American Petroleum Institute (API). An oil with this trademark symbol conformsto the current engine and emission systemprotection standards and fuel economyrequirements of the International LubricantsSpecification Advisory Committee (ILSAC).
To top up the engine oil level do thefollowing:
1. Clean the area surrounding the engineoil filler cap before you remove it.
2. Remove the engine oil filler cap. SeeUnder Hood Overview (page 304). Turnit counterclockwise and remove it.
3. Add engine oil that meets Fordspecifications. See Capacities andSpecifications (page 380). You may haveto use a funnel to pour the engine oil intothe opening.
4. Recheck the oil level.
5. If the oil level is correct, replace thedipstick and make sure it is fully seated.
6. Replace the engine oil filler cap. Turn itclockwise until you feel a strongresistance.
Note: Do not add oil further than themaximum mark. Oil levels above themaximum mark may cause engine damage.
Note:Make sure you install the oil filler capcorrectly.
Note:Soak up any spillage with anabsorbent cloth immediately.
OIL CHANGE INDICATOR RESET

If you use oil and fluids that do not meet thedefined specification and viscosity grade,this may lead to:
•Component damage, which the vehiclewarranty does not cover.
•Longer engine cranking periods.
•Increased emission levels.
•Reduced engine performance.
•Reduced fuel economy.
•Degraded brake performance.
We recommend Motorcraft motor oil for yourvehicle. If Motorcraft oil is not available, usemotor oils of the recommended viscositygrade that meet API SN requirements anddisplay the API Certification Mark for gasolineengines. Do not use oil labeled with API SNservice category unless the label alsodisplays the API 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 ExtremelyCold 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.
