Maintenance and Specifications Some stations offer fuels posted as ЉRegularЉ with an octane rating below 87, particularly in high altitude areas. Fuels with octane (R+M)/2 METHOD levels below 87 are not recommended for either engine. Do not be concerned if your engine sometimes knocks lightly. However, if it knocks heavily while you are using fuel with the recommended octane rating, see your authorized dealer to prevent any engine damage. 87 Fuel quality If you are experiencing starting, rough idle or hesitation driveability problems during a cold start, try a different brand of unleaded gasoline. If the problems persist, see your authorized dealer. Do not add aftermarket fuel additive products to your fuel tank. It should not be necessary to add any aftermarket products to your fuel tank if you continue to use high quality fuel of the recommended octane rating. These products have not been approved for your engine and could cause damage to the fuel system. Repairs to correct the effects of using an aftermarket product in your fuel may not be covered by your warranty. Many of the world's automakers approved the World-Wide Fuel Charter that recommends gasoline specifications to provide improved performance and emission control system protection for your vehicle. Gasolines that meet the World-Wide Fuel Charter should be used when available. Ask your fuel supplier about gasolines that meet the World-Wide Fuel Charter. Cleaner air Ford endorses the use of reformulated "cleaner-burning" gasolines to improve air quality. Running out of fuel Avoid running out of fuel because this situation may have an adverse effect on powertrain components. If you have run out of fuel: • You may need to cycle the ignition from off to on several times after refueling to allow the fuel system to pump the fuel from the tank to the engine. On restarting, cranking time will take a few seconds longer than normal. With keyless ignition, just start the engine. Crank time will be longer than usual. 318 2011 MKS (mks) Owners Guide, 2nd Printing USA (fus)

levels below 87 are not
recommended for either engine. Do not be concerned if your engine
sometimes knocks lightly. However, if it knocks heavily while you are
using fuel with the recommended octane rating, see your authorized
dealer to prevent any engine damage.
Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of unleaded gasoline.
If the problems persist, see your authorized dealer.
Do not add aftermarket fuel additive products to your fuel tank. It
should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating. These products have not been approved for your engine and
could cause damage to the fuel system. Repairs to correct the effects of
using an aftermarket product in your fuel may not be covered by your
warranty.
Many of the world’s automakers approved the World-Wide Fuel Charter
that recommends gasoline specifications to provide improved

Gasolines that meet the World-Wide Fuel Charter should be used when
available. Ask your fuel supplier about gasolines that meet the

Cleaner air
Ford endorses the use of reformulated “cleaner-burning” gasolines to
improve air quality.

effect on powertrain components.
