FUEL QUALITY
SELECTING THE CORRECT FUEL -FLEX FUEL – ETHANOL
Flex fuel vehicles have one of the followingidentifiers:
•Yellow fuel filler cap.
•Yellow bezel around the fuel filler inlet.
•Yellow fuel filler housing.
•Yellow E85 label on the fuel tank fillerdoor.
Your vehicle operates on regular unleadedgasoline with a minimum pump (R+M)/2octane rating of 87 or regular unleadedgasoline blended with a maximum of 85%ethanol (E85).
Some fuel stations, particularly those inhigh altitude areas, offer fuels posted asregular unleaded gasoline with an octanerating below 87. The use of these fuelscould result in engine damage that will notbe covered by 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 wellas other conditions, for example whentowing a trailer. See Towing a Trailer(page 418).
Do not be concerned if the enginesometimes knocks lightly. However, if theengine knocks heavily while using fuel withthe recommended octane rating, contactan authorized dealer to prevent any enginedamage.
We recommend Top Tier detergentgasolines, where available to help minimizeengine deposits and maintain optimalvehicle and engine performance.

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.
•Fuels containing more than 85%ethanol or E100 fuel.
•Fuels containing methanol.
•Fuels containing metallic-basedadditives, including manganese-basedcompounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel, using leaded fuel isprohibited by law.
The use of fuels with metallic compoundssuch as methylcyclopentadienylmanganese tricarbonyl, which is amanganese-based fuel additive, will impairengine performance and affect theemission control system.

SWITCHING BETWEEN E85 ANDGASOLINE
We do not recommend repeatedlyalternating between E85 and gasoline. Ifyou switch from using E85 to gasoline, orfrom gasoline to E85, add as much fuel aspossible, at least half a tank. Drive yourvehicle immediately for a minimum of 5 mi(8 km) to allow it to adapt to the changein ethanol concentration. If you use E85exclusively, we recommend that you fillthe fuel tank with regular unleadedgasoline at each scheduled oil change.

ENGINE OIL CAPACITY AND
SPECIFICATION - 3.3L
Use oil that meets the definedspecification and 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 conformsto current engine, emission system andfuel economy performance standards ofILSAC.
We recommend Motorcraft® motor oil foryour vehicle. If Motorcraft® oil is notavailable, use motor oils of therecommended viscosity grade that displaythe API Certification Mark for gasolineengines.
Do not use supplemental engine oiladditives because they are unnecessaryand could lead to engine damage that yourvehicle warranty does not cover.
