Fuel recommendation
General information
Depending on the region, many gas stations sell
fuel that has been customized to winter or
summer conditions. Fuel that is available in win‐
ter, for instance helps make a cold start easier.
NOTE
Incorrect fuels can damage the fuel system and
the engine. There is a risk of damage to prop‐
erty. Do not use fuels with a higher percentage
of ethanol than recommended. Do not refuel
with fuels containing methanol, e.g. M5 to
M100.
Gasoline
General information
For the best fuel efficiency, the gasoline should
be sulfur-free or very low in sulfur content.
Fuels that are marked on the gas pump as con‐
taining metal must not be used.
NOTE
Fuels with a maximum ethanol content of 10 %,
i. e., E10, may be used for refueling.
Fuel that does not comply with the minimum
quality can compromise engine function or
cause engine damage. There is a risk of dam‐
age to property. Do not fill with fuel that does
not comply with the minimum quality.
Ethanol should meet the following quality stan‐
dards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current standard in each
case.

CAUTION
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 num‐
ber — for a few tank fills. To avoid harmful en‐
gine deposits, it is highly recommended to pur‐
chase gasoline from Top Tier retailers.
Failure to comply with these recommendations
may result in the need for unscheduled mainte‐
nance.
Recommended fuel grade
BMW recommends AKI 91.
Minimum fuel grade
BMW recommends AKI 89.
If you use gasoline with this minimum AKI Rating,
the engine may produce knocking sounds when
starting at high external temperatures. This has
no effect on the engine life.
