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 com-
pletely 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 recov-
ery system.
The fuel tank is full when the filler nozzle clicks
off the first time.

cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can

Fuel specifications

Gasoline engine: required fuel
Do not refuel with leaded fuel; otherwise,
the catalytic converter will be damaged.
Do not refuel with E85, i.e. fuel containing 85%
ethanol, nor with FlexFuel; otherwise, the
engine and fuel supply system will be dam-

Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:

occur.<
>
335i/xDrive: 89.
If you use gasoline with this minimum AKI Rat-
ing, 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 speci-
fied minimum fuel grade. Otherwise the
engine could be damaged.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing 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 condi-
tions 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
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 refu-
eling with the wrong fuel, e. g. with gasoline, do
not start the engine; otherwise, engine damage
may occur.<
