Fuel

Vehicle equipment

This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and sys‐
tems.

Fuel quality

Gasoline

For the best fuel economy, the gasoline should
be sulfur-free or very low in sulfur content.
Do not use fuels that are labeled at the fuel pump
as containing metals.

Only refuel with lead-free gasoline without
metal additives

Do not refuel with leaded gasoline or gasoline
with metal additives, e. g., manganese or iron;
otherwise, the catalytic converter and other
components will be permanently damaged.◀

Fuels with a maximum ethanol content of 10 %,
i.e., E10, may be used for refueling.
The ethanol should fulfill the following quality
standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: always adhere to the currently applicable
standard.

Do not refuel with ethanol E85
Do not refuel with E85, i.e., fuel with an

ethanol content of 85 %, or with Flex Fuel, as this
would damage the engine and fuel supply sys‐
tem.◀

The engine is knock controlled. Therefore, you
can refuel with different gasoline qualities.

Recommended fuel quality

BMW recommends AKI 91.

Minimum fuel grade

BMW recommends AKI 89.

Minimum fuel grade
Do not fill up with fuel below the specified

minimum quality; otherwise, the engine may not
run properly.◀

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.

Minimum fuel grade
The use of poor-quality fuels may result in

harmful engine deposits or damage. Addition‐
ally, problems relating to drivability, starting and
stalling, especially under certain environmental
conditions such as high ambient temperature
and high altitude, may occur.
If drivability problems are encountered, we rec‐
ommend switching to a high quality gasoline
brand and a higher octane grade — AKI number
— for a few tank fills. To avoid harmful engine
deposits, it is highly recommended to purchase
gasoline from BP or Top Tier retailers.
Failure to comply with these recommendations
may result in the need for unscheduled mainte‐
nance.◀

Diesel

Ultra-Low Sulfur Diesel

The engine of your BMW is designed for diesel
with a low sulfur content:
Ultra-low sulfur diesel ASTM D 975-xx.
