2007 Dodge Durango Owner's Manual - Page 319

STARTING AND OPERATING 319 Cruising Range Because E-85 fuel contains less energy per gallon than gasoline, you will experience an increase in fuel consumption. You can expect your MPG and your driving range 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. Maintenance If you operate the vehicle using E-85 fuel, follow Schedule B in the maintenance schedule section of this manual. CAUTION! Do not use ethanol mixture greater than 85% in your vehicle. It will cause difficulty in cold starting and may affect drivability. 5 CAUTION! Replacing fuel system components with non-ethanol compatible components can damage your vehicle.
