2017 BMW X3 octane

FuelVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
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 helps make a cold start easier, for exam‐
ple.
Information ATTENTION
Even fuels that conform to the specifica‐
tions can be of low quality. This may cause en‐
gine problems, e.g., poor engine start-up be‐
havior, poor handling and/or poor performance.
There is a risk of damage to property. In case
of engine problems, switch gas stations or use
a brand name fuel with a higher octane rat‐
ing.◀
Gasoline
General information For the best fuel efficiency, the gasoline
should be sulfur-free or very low in sulfur con‐
tent.
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.
Ethanol should meet the following quality
standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current standard in each
case.
Information ATTENTION
Do not press the Start/Stop button after
refueling with the wrong fuel. Furthermore, the
catalytic converter is permanently damaged.
There is a risk of damage to property. Do not
refuel or add the following in the case of gaso‐
line engines:▷Leaded gasoline.▷Metallic additives, e.g., manganese or iron.
Do not press the Start/Stop button after refuel‐
ing with the wrong fuel. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.◀
ATTENTION
Incorrect fuels can damage the fuel sys‐
tem and the engine. There is a risk of damage
to property. Do not use a fuel with a higher
ethanol percentage than recommended or one
with other types of alcohol, e.g., M5 to M100.◀
ATTENTION
Fuel that does not comply with the mini‐
mum quality can compromise engine function
or cause engine damage. There is a risk of
damage to property. Do not fill with fuel that
does not comply with the minimum quality.◀

CAUTION
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.
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.
Diesel
Information ATTENTION
Do not press the Start/Stop button after
refueling with the wrong fuel. There is a risk of
damage to property.
Observe the following for diesel engines:▷Use only Ultra-Low Sulfur Diesel. Maxi‐
mum content of biodiesel: 5 %, B5.▷Do not use rapeseed methyl ester RME.▷Do not use biodiesel above 5 %, B5.▷Do not use gasoline.▷No diesel additives.Do not press the Start/Stop button after refuel‐
ing with the wrong fuel. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.◀
Low-Sulfur Diesel
The engine of your BMW is designed for diesel
with low sulfur content:
Ultra-Low Sulfur Diesel ASTM D 975-xx.
xx: comply with the current standard in each
case.
Use only Ultra-Low Sulfur Diesel.
The fraction of biodiesel in the fuel must not
exceed 5 %, referred to as B5. Do not use gas‐
oline. If you do fill the tank with the wrong fuel,
e.g., gasoline, do not start the engine as this
may damage the engine.
In the case of incorrect refueling, contact a
dealer’s service center or another qualified
service center or repair shop or Roadside As‐
sistance.
If the fuel pump nozzle does not fit in the filler
pipe of your BMW, please check to ensure that
you are refueling at a diesel fuel pump that is
equipped with a diesel fuel pump nozzle.
In the event the Ultra-Low Sulfur Diesel fuel
cannot be fully inserted into the fuel filler neck,
please contact BMW Roadside Assistance for
instructions on how to add fuel.

gation, Entertainment and Communication.Seite 201FuelMobility201
