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
winter, e.g., helps make a cold start easier.
NOTE
Incorrect fuels can damage the fuel sys‐
tem and the engine. There is a risk of damage
to property. Do not use fuels with a higher per‐
centage of ethanol than recommended. Do not
refuel with fuels containing methanol, e.g. M5
to M100.◀
Gasoline
General information
NOTE
For the best fuel efficiency, the gasoline
should be sulfur-free or very low in sulfur con‐
tent.
Fuel that does not comply with the mini‐
mum quality can compromise engine function
or cause engine damage. There is a risk of
property damage. Do not fill with fuel that does
not comply with the minimum quality.◀
Fuels that are marked on the gas pump as con‐
taining metal must not be used.
Fuels with a maximum ethanol content of
10 %, i. e., E10, may be used for refueling.
CAUTION
Ethanol should meet the following quality
standards:
The use of poor-quality fuels may result
in harmful engine deposits or damage. Addi‐
tionally, problems relating to drivability, start‐
ing and stalling, especially under certain envi‐
ronmental conditions such as high ambient
temperature and high altitude, may occur.
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current standard in each
case.
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
purchase gasoline from Top Tier retailers.
Failure to comply with these recommendations
may result in the need for unscheduled main‐
tenance.◀
Recommended fuel grade
BMW recommends AKI 91.
Minimum fuel grade
BMW recommends AKI 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.
