2015 BMW M6 CONVERTIBLE fuel consumption

Saving 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.
General information Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
Carrying out certain measures, such as a mod‐
erate driving style and regular maintenance,
can influence fuel consumption and the envi‐
ronmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.
Closing the windows Open windows increase air resistance and
therefore lead to greater fuel consumption.Tires
General information
Tires can affect fuel consumption in various
ways, e.g., tire size may influence fuel con‐
sumption.
Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflation
pressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away immediately
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the quickest way of warming the cold
engine up to operating temperature.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and proactively reduces fuel
consumption.
Avoid high engine speeds
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Use 1st gear to get the vehicle moving. Start‐
ing with the 2nd gear, accelerate rapidly. WhenSeite 170Driving tipsSaving fuel170

accelerating, shift up before reaching high en‐
gine speeds.
When you reach the desired speed, shift into
the highest applicable gear and drive with the
engine speed as low as possible and at a con‐
stant speed.
If necessary, observe the gear shift indicator of
the vehicle, refer to page 92.
Use coasting When approaching a red light, take your foot
off the accelerator and let the vehicle coast to
a halt.
For going downhill take your foot off the accel‐
erator and let the vehicle roll.
The flow of fuel is interrupted while coasting.
Switch off the engine during
longer stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Auto Start/Stop function The Auto Start/Stop function of your vehicle
automatically switches off the engine during a
stop.
If the engine is switched off and then restarted
rather than leaving the engine running con‐
stantly, fuel consumption and emissions are
reduced. Savings can begin within a few sec‐
onds of switching off the engine.
In addition, fuel consumption is also deter‐
mined by other factors, such as driving style,
road conditions, maintenance or environmental
factors.Switch off any functions that
are not currently needed
Functions such as seat heating and the rear
window defroster require a lot of energy and
reduce the range, especially in city and stop-
and-go traffic.
Reel off these functions if they are not needed.
Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle efficiency and operating life.
The maintenance should be carried out by
your service center.
Also note the BMW Maintenance System, refer
to page 193.Seite 171Saving fuelDriving tips171

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. The respectively applicable country
provisions must be observed when using the
respective features 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.
When a dynamic driving style is used, such as
when cornering fast, the system is unable to
measure the engine oil level. With this driving
style, measure the engine oil level using a de‐
tailed measurement, refer to page 190.
The vehicle is equipped with electronic oil
measurement.
The electronic oil measurement has two meas‐
uring principles:
▷Status display▷Detailed measurementElectronic 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 190.
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.
