General information This information is for Flexible Fuel vehicles (FFV) only. FFV vehicles can be identified by the fuel filler door label that states Ethanol (E-85) or Unleaded Gasoline Only. This section only covers those subjects that are unique to Flexible Fuel vehicles. Fuel requirements Your vehicle will operate on both unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research octane number 91), or E-85 fuel, or any mixture of these two. For the best starting and vehicle driveability results, do not continually switch between E-85 and unleaded regular gasoline. If you must switch fuels, NISSAN recommends the following: ● do not switch when the fuel gauge indicates less than 1/4 full ● add more than 5 gallons of fuel ● operate the vehicle immediately after refueling for a period of at least 5 minutes NOTE: When the ambient temperature is above 90°F (32°C), you may experience hard starting and rough idle following start up even if the above recommendations are followed. Starting The characteristics of E-85 fuel make it unsuitable for use when ambient temperatures fall below 0°F (-18°C). In the range of 0°F (-18°C) to 32°F (0°C), you may experience an increase in the time it takes for you engine to start, and a deterioration in drivability (sags and/or hesitations) until the engine is fully warmed up. Fuel consumption Because E-85 fuel contains less energy per gallon than gasoline, you will experience an increase in fuel consumption. You can expect your fuel mileage to decrease by about 30% compared to gasoline operation. Replacement parts Many components in your Flexible Fuel Vehicle (FFV) are designed to be compatible with ethanol. Always be sure that your vehicle is serviced with correct ethanol compatible parts. CAUTION Only vehicles with the E-85 filler door label can operate on E-85. Fuel system or other damage can occur if E-85 is used in vehicles that are not designed to run on E-85. CAUTION Replacing fuel system components with non-ethanol compatible components can damage your vehicle and may also affect the warranty coverage. Maintenance If you operate your vehicle using E-85 fuel, follow the correct maintenance log shown in the "NISSAN Service and Maintenance Guide". Ethanol Fuel (E-85) E-85 is a mixture of approximately 85% fuel ethanol and 15% unleaded gasoline. WARNING ● Ethanol vapors are extremely flammable and could cause serious personal injury. ● Never have any smoking materials lit in or near the vehicle when removing the fuel filler cap or filling the tank. ● Do not use E-85 as a cleaning agent and never use it near an open flame. CAUTION Do not use ethanol mixture greater than 85% in your vehicle. It will cause difficulty in cold starting and may affect drivability. Technical and consumer information 9-5
