Maintenance and Specifications Unleaded Gasoline engines If you are experiencing starting, rough idle or hesitation driveability problems during a cold start, try a different brand of "Regular" unleaded gasoline. "Premium" unleaded gasoline is not recommended (particularly in the United States) because it may cause these problems to become more pronounced. If the problems persist, see your authorized Mazda dealership. FFV engine (if equipped) Your FFV will operate well on ordinary "Regular" unleaded gasoline, but only the highest quality fuel ethanol will provide the same level of protection and performance. To identify if your vehicle is an FFV, check your VIN or the label on the inside of your fuel filler door. When checking the VIN, look for the engine type identifier (8th character). If your vehicle is an FFV, then the character will be labeled as a "K." If you operate your vehicle 50% or more of the time on ethanol, you should follow a different maintenance schedule. See the Service Maintenance Section for more information. If you are experiencing a rough or rolling idle after start-up with the outside temperature above 27° C (80° F), the idle should improve within 10 to 30 seconds. If the problems persist below this temperature, see your authorized Mazda dealership. Cleaner air Mazda 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 affect 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. • Your "Check Engine" indicator may come on. For more information on the "Check Engine" indicator, refer to the Instrument Cluster chapter. Fuel Filter For fuel filter replacement, see your authorized Mazda dealership. Refer to the service maintenance section for the appropriate intervals for changing the fuel filter. 255
