Observe the following when refueling When handling fuels, follow the safety instructions provided at filling stations, otherwise there is a risk of personal injury or property damage.< When refueling, insert the filler nozzle completely into the filler pipe. Avoid lifting the filler nozzle while filling the tank, as that would lead to > premature pump shutoff > reduced efficiency of the fuel-vapor recovery system. The fuel tank is full when the filler nozzle clicks off the first time. > 335i/xDrive: 89. 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 Ξ ethanol or other oxygenates with up to 2.8Ξ oxygen by weight, that is, 15Ξ MTBE or 3Ξ methanol plus an equivalent amount of co-solvent, will not void the applicable warranties with respect to defects in materials or workmanship. The use of poor-quality fuels may result in driveability, starting and stalling problems especially under certain environmental conditions such as high ambient temperature and high altitude. Should you encounter driveability problems which 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.< Fuel tank capacity Refuel as soon as possible once your cruising range falls below 30 miles/ 50 km, otherwise engine functions are not ensured and damage can occur.< Gasoline engine Approx. 16.1 US gallons/61 liters, including the reserve capacity of 2.1 US gallons/8 liters.

Otherwise the engine and fuel supply system will be damaged.< BMW Advanced Diesel: required fuel Ultra-low sulfur diesel The engine of your BMW is designed for diesel with low sulfur content: Ultra-low sulfur diesel ASTM D 975-07a. Refuel with ultra-low sulfur diesel only. The percentage of biodiesel in the fuel may not exceed 5%; this type of fuel is referred to as B5. Do not refuel with gasoline. After refueling with the wrong fuel, e.g. with gasoline, do not start the engine; otherwise, engine damage may occur.< 191 Super Premium Gasoline/AKI 91 This gasoline is highly recommended.
