FUEL QUALITY
SELECTING THE CORRECT FUEL
Your vehicle operates on regular unleadedgasoline with a minimum pump (R+M)/2octane rating of 87.
Some fuel stations, particularly those in highaltitude areas, offer fuels posted as regularunleaded gasoline with an octane ratingbelow 87. The use of these fuels could resultin engine damage that will not be coveredby the vehicle Warranty.
For best overall vehicle and engineperformance, premium fuel with an octanerating of 91 or higher is recommended. Theperformance gained by using premium fuelis most noticeable in hot weather as well asother conditions, for example when towinga trailer. See Towing a Trailer (page 304).
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.
We recommend Top Tier detergentgasolines, where available to help minimizeengine deposits and maintain optimal vehicleand engine performance.
For additional information, visitwww.toptiergas.com.
Note:Use of any fuel for which the vehiclewas not designed can impair the emissioncontrol system, cause loss of vehicleperformance, and cause damage to theengine which may not be covered by thevehicle Warranty.
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, which is a manganese-based fueladditive, will impair engine performance andaffect the emission control system.

ENGINE OIL CAPACITY AND
SPECIFICATION - 2.0L
Use oil that meets the defined specificationand viscosity grade.
If you do not use oil that meets the definedspecification and viscosity grade, it couldresult in:
•Component damage that your vehiclewarranty does not cover.
•Longer engine cranking periods.
•Increased emission levels.
•Reduced vehicle performance.
•Reduced fuel economy.
An oil that displays this symbol conforms tocurrent engine, emission system and fueleconomy performance standards of ILSAC.
We recommend Motorcraft motor oil for yourvehicle. If Motorcraft oil is not available, usemotor oils of the recommended viscositygrade that display the API Certification Markfor gasoline engines.
Do not use supplemental engine oil additivesbecause they are unnecessary and couldlead to engine damage that your vehiclewarranty does not cover.

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.
You can drive high performance vehicles insuch a way that may lead to higher oilconsumption including extended time at highengine speeds, high loads, engine braking,hard cornering maneuvers, track and off-roadusage. Under these conditions, oilconsumption of approximately 1 quart per500 miles (1 liter per 800 km) is possible.Check the engine oil level at every refuelingand adjust to maintain proper levels to avoidengine damage.
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.
Owner Checks and Services
Make sure you perform the following basicmaintenance checks and inspections.
