>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
Do not fill the tank with leaded fuel, as this 
would cause permanent damage to the 
catalytic converter.
Do not fill the tank with E85, i.e. fuel containing 
85 % ethanol, nor with FlexFuel. Otherwise the 
engine and fuel supply system will be dam-
aged.<
Required fuel
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/xi: 87
>335i/xi: 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 % 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.
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 maintenance.<
