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.

Fuel tank capacity

Approx. 16.1 US gallons/61 liters, including the
reserve capacity of 2.1 US gallons/8 liters.

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.

Fuel specifications

Gasoline engine: required fuel

Do not refuel with leaded fuel; otherwise,
the catalytic converter will be damaged.

Do not fill the tank with E85, i.e. fuel containing
85

Ξ ethanol, nor with FlexFuel. Otherwise, the

engine and fuel supply system will be dam-
aged.

Super Premium Gasoline/AKI 91

This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:

328i/xDrive: 87

335i, 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 2.8

Ξ oxygen by weight,

that is, 15

Ξ MTBE or 3Ξ methanol plus an

equivalent amount of cosolvent, will not void the
applicable warranties with respect to defects in
materials or workmanship.

The use of poor-quality fuels may result in
drivability, starting and stalling problems

especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability 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.
