2014 BMW 6 SERIES COUPE engine

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.
Fuel recommendation
Note General fuel quality
Even fuels that conform to the specifica‐
tions can be of low quality. This may cause en‐
gine problems, for instance poor engine start-
up behavior, poor handling and/or poor
performance. Switch gas stations or use a
brand name fuel with a higher octane rating.◀
Gasoline
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.
Refuel only with unleaded gasoline with‐
out metallic additives.
Do not refuel with any leaded gasoline or gaso‐
line with metallic additives, e. g. manganese or
iron, as this can cause permanent damage to
the catalytic converter and other compo‐
nents.◀
Fuels with a maximum ethanol content of
10 %, i. e., E10, may be used for refueling.
Ethanol should satisfy the following quality
standards:
US: ASTM 4806–xxCAN: CGSB-3.511–xx
xx: comply with the current standard in each
case.
Do not use a fuel with a higher percent‐
age of ethanol
Do not use a fuel with a higher ethanol per‐
centage than recommended or one with other
types of alcohol, e.g. M5 to M100; otherwise
this could damage the engine and fuel supply
system.◀
Recommended fuel grade BMW recommends AKI 91.
Minimum fuel grade
BMW recommends AKI 89.
Minimum fuel grade
Do not use any gasoline below the mini‐
mum fuel grade as this may impair engine per‐
formance.◀
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.
Fuel quality
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.Seite 188MobilityFuel188

Opening the hood Working in the engine compartment
Never attempt to perform any service or
repair operations on your vehicle without the necessary professional technical training.If you are unfamiliar with the statutory guide‐
lines, have any work on the vehicle performed
only by a service center.
If work is not carried out properly, there is a
danger of subsequent damage and related
safety hazards.◀Seite 202MobilityEngine compartment202

ment
Never reach into spaces or gaps in the engine
compartment; otherwise, there is a risk of in‐
jury, e.g., from rotating or hot parts.◀

Engine oilVehicle features and options
This 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.
General information
The engine oil consumption is dependent on
the driving style and driving conditions.
The engine oil consumption can increase in
case of, for example:▷Sporty driving.▷Break-in the engine.▷Idling of the engine.▷Usage of non-approved engine oil grades.
Therefore, regularly check the engine oil level
after refueling.
The vehicle is equipped with electronic oil
measurement.
The electronic oil measurement has two meas‐
uring principles:
▷Status display▷Detailed measurement
Electronic oil measurement
Status display
The concept
The engine oil level is monitored electronically
while driving and shown on the Control Dis‐
play.
If the engine oil level reaches the minimum
level, a check control message is displayed.
Requirements
A current measured value is available after ap‐
prox. 30 minutes of driving. During a shorter
trip, the status of the last, sufficiently long trip
is displayed.
With frequent short-distance trips, regularly
perform a detailed measurement.
Displaying the engine oil level
On the Control Display:1."Vehicle info"2."Vehicle status"3. "Engine oil level"
Engine oil level display messages
Different messages appear on the display de‐
pending on the engine oil level. Pay attention
to these messages.
If the engine oil level is too low, within the next
125 miles/200 km Add engine oil, refer to
page 205.
Engine oil level too low
Add engine oil immediately; otherwise,
an insufficient amount of engine oil could re‐
sult in engine damage.◀
Take care not to add too much engine oil. Too much engine oil
Have the vehicle checked immediately;
otherwise, surplus engine oil can lead to en‐
gine damage.◀

Detailed measurement
The concept In the detailed measurement the engine oil
level is checked and displayed via a scale.
During the measurement, the idle speed is in‐
creased somewhat.
General information
A detailed measurement is only possible with
certain engines.
Requirements▷Vehicle is on level road.▷Steptronic transmission: selector lever in
selector lever position N or P and accelera‐
tor pedal not depressed.▷Engine is running and is at operating tem‐
perature.
Performing a detailed measurement
In order to perform a detailed measurement of
the engine oil level:
1."Vehicle info"2."Vehicle status"3. "Measure engine oil level"4."Start measurement"
The engine oil level is checked and displayed
via a scale.
Time: approx. 1 minute.
Adding engine oil General information
Switch off the ignition and safely park the vehi‐
cle before engine oil is added.
Oil filler neck
Only add engine oil when the message is dis‐
played in the instrument cluster.
Add 1 US quart/liter.
With 8 cylinder engine:
Add 2 US quarts/liters.
Adding engine oil
Add oil within the next 125 miles/200 km;
otherwise, this may cause engine damage.◀
Do not add too much engine oil
When too much engine oil is added, im‐
mediately have the vehicle checked, otherwise,
this may cause engine damage.◀
Protect children
Keep oil, grease, etc., out of reach of chil‐
dren and observe the warnings on the contain‐
ers to prevent health risks.◀
Engine oil types to add Hints No oil additives
Oil additives may lead to engine dam‐
age.◀
Viscosity grades for engine oils
When selecting an engine oil, ensure that
the engine oil belongs to one of the viscosity
grades SAE 0W-40, SAE 0W-30, SAE 5W-40,
Seite 205Engine oilMobility205
Online Edition for Part no. 01 40 2 956 387 - X/14

and SAE 5W-30 or malfunctions or engine
damage may occur.◀
The engine oil quality is critical for the life of
the engine.
Approved engine oil types
You can add engine oils with the following
specifications:Gasoline engineBMW Longlife-01.BMW Longlife-01 FE.
Additional information about the approved
types of engine oils can be obtained from the
service center.
Alternative engine oil types If the approved engine oils are not available, up
to 1 US quart/liter of an engine oil with the fol‐
lowing specification can be added:
Gasoline engineAPI SM or superior grade specification.
Engine oil change:
The vehicle manufacturer recommends that
you let the service center change the motor oil.

CoolantVehicle 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.
Hints Danger of burns from hot engine
Do not open the cooling system while
the engine is hot; otherwise, esliding coolant
may cause burns.◀
Suitable additives
Only use suitable additives; otherwise,
engine damage may occur. The additives are
harmful to your health.◀
Coolant consists of water and additives.
Not all commercially available additives are
suitable for the vehicle. Information about the
suitable additives are available from the service
center.
Coolant level
General information If there is no Min. and Max. mark in the filler
neck of the coolant reservoir, have the coolant
level checked if needed by your service center
and add coolant as needed.
Depending on the engine installation, the cool‐
ant reservoir is located on the right side or the
left side of the engine compartment.Checking1.Let the engine cool.2.Turn the lid of the coolant reservoir slightly
counterclockwise to allow any excess
pressure to dissipate, then open it.3.Open the coolant reservoir lid.4.The coolant level is correct if it lies be‐
tween the minimum and maximum marks
in the filler neck.Seite 207CoolantMobility207
