Typical octane rating label
Do not be concerned if your vehicle sometimes knocks lightly.
However, if it knocks heavily under most driving conditions on
the recommended octane fuel, see your dealer or a qualified
service techncian to prevent any engine damage.
Fuel Quality
If you are experiencing starting, rough idle or hesitation
problems, try a different brand of fuel. If the condition persists,
see your dealer or a qualifies service technician.
The American Automobile Manufacturers Association (AAMA)
issued a gasoline specification to provide information on high
quality fuels that optimize the performance of your vehicle. We
recommend the use of gasolines that meet the AAMA
specification if they are available.
It should not be necessary to add any aftermarket products to
your fuel tank if you continue to use a high-quality fuel.
Gasolines for clean air
Ford approves the use of gasolines to improve air quality,
including reformulated gasolines that contain oxygenates such as
a maximum of 10% ethanol or 15% MTBE. There should be no
more than 5% methanol with cosolvents and additives to protect
the fuel system.
