Fuel tank capacity Approx. 17.7 US gal./67 liters, including the reserve capacity of approx. 2 US gal./8 liters. Never attempt to continue driving until the tank is completely empty; this can negatively affect engine function and can damage the vehicle.< Fuel specifications Never use leaded gasoline. Otherwise, you will damage the catalytic converter. Do not use flex fuel or E85, i.e. fuel that is comprised of 85% ethanol as these can damage the engine and fuel supply system.< The use of poor-quality fuels may result in stalling, starting and drivability problems especially under certain environmental conditions such as high ambient temperature and high altitude. Should you encounter drivability problems that you suspect could be related to the fuel you are using, we recommend that you respond by switching to a recognized high-quality brand such as gasoline that is advertised as Top Tier Detergent Gasoline. Failure to comply with these recommendations may also result in unscheduled maintenance.< Required fuel Super Premium Gasoline/AKI 91 This gasoline is highly recommended. However, you may also use gasoline with a lower AKI rating. The minimum AKI rating is 87. If you use gasoline with this minimum AKI rating, the engine may produce knocking sounds when starting at high outside temperatures. This has no effect on the engine life. Do not use any gasoline below the specified minimum fuel grade. Otherwise, the engine could be damaged.< Use high-quality brands Field experience has indicated significant differences in fuel quality: volatility, composition, additives, etc., among gasolines offered for sale in the United States and Canada. Fuels containing up to and including 10% ethanol or other oxygenates with up to 2.8% oxygen by weight, that is, 15% MTBE or 3% methanol plus an equivalent amount of co-solvent, will not void the applicable warranties with respect to defects in materials or workmanship. 93 Online Edition for Part no. 01 41 2 602 348 - © 02/09 BMW AG Reference Mobility Driving tips Controls At a glance
