gasoline BMW Z4 2015 E89 Owner's Manual

Fuel recommendationVehicle equipmentThis 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
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
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 with‐
out 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
system.◀The engine is knock controlled. Therefore, you
can refuel with different recommended fuel
grades.
Recommended fuel grade
BMW recommends AKI 91.
Minimum fuel grade
BMW recommends AKI 89.
Minimum fuel grade
Do not fill up with fuel below the speci‐
fied 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. 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 BP or Top Tier retail‐
ers.
Failure to comply with these recommendations
may result in the need for unscheduled main‐
tenance.◀Seite 226MobilityFuel recommendation226
