verter will result. Do not use E85, i.e., fuel that consists of 85% ethanol, or Flex Fuel. Otherwise permanent damage to the engine and the fuel supply system will result.< Required fuel Super Premium Gasoline/AKI 91 Place the fuel filler cap in the bracket attached to the fuel filler flap. When refueling, insert the filler nozzle completely into the filler pipe. Avoid raising the filler nozzle during refueling; otherwise this leads to > premature pump shutoff > a reduced efficiency of the fuel-vapor recovery system. The fuel tank is full when the filler nozzle clicks off the first time. This gasoline is highly recommended. However, you may also use gasoline with less AKI. 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 affect on the engine life. Do not use gasoline below the specified minimum quality, otherwise engine damage can result.< Controls Reference Mobility Communications Entertainment Navigation Driving tips Fuel tank capacity Approx. 18.5 US gal/70 liters, including the reserve capacity of approx. 2.1 US gal/8 liters. 550i: approx. 2.6 US gal/10 liters reserve capacity.

The use of poor-quality fuels may result in drivability, starting and stalling problems especially under certain environmental conditions such as high ambient temperature and high altitude.

Failure to comply with these recommendations may also result in unscheduled maintenance.< Fuel filler cap Closing Fit the cap and turn it clockwise until you clearly hear a click.
