Maintenance and care fuel, see your dealer or a qualified service technician to prevent any engine damage. SHO engines Your vehicle is designed to use premium gasoline for optimum performance with an (R + M)/2 octane rating of 91 or higher. Gasolines with lower octane ratings can be used but performance may decrease. We do not recommend gasolines labeled as "premium" in high altitude areas that are sold with octane ratings less than 91. 91 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 qualified 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. Cleaner 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. Calculating fuel economy To accurately calculate your vehicle's fuel economy: 141
