Engine oilChecking oil level 1 Park the vehicle on a level surface
2 Shut the engine off after it has
reached normal operating tempera-
ture
3 After approx. one minute, pull the
dipstick out and wipe it off with a
clean lint-free cloth, paper towel, or
similar material
4 Carefully push the dipstick all the way
into the guide tube and pull it out
again
5 The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.
The oil volume between the two marks
on the dipstick corresponds to approx.
1.4 US quarts (1.3 liters).
Adding engine oil Wait until the level has dropped to just
above the lower mark before adding oil.
However, never let the oil drop below
the lower mark.
Do not fill beyond the upper mark on
the dipstick. Excess oil will damage the
engine.
To obtain a correct reading when
rechecking the oil level after adding
lubricant, start the engine and allow it
to run, then switch it off and proceed as
described in the section on "Checking
oil level".
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This is also true for the

The BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and oper-
ating safety – and as cost-effectively as
possible for you.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining the resale
value of the vehicle. Service Interval DisplayAdvanced technology is employed to
calculate the optimal maintenance
intervals. These are then indicated in
the Service Interval Display. While
conventional systems rely solely on
distance traveled to determine when
service is due, the BMW Maintenance
System considers the actual conditions
under which the vehicle operates,
because miles can be traveled in many
different ways:
From the point of view of maintenance,
for example, 62,000 miles (100,000 km)
short-distance driving are not equal to
the same 62,000 miles (100,000 km) of
long-distance travel.
The BMW Maintenance System
includes the Engine Oil Service and
Inspections I and II.
Determining the maintenance intervals
according to the actual use of the
vehicle covers every kind of operating
situation. Those who are outright
"Sunday drivers," driving fewer than
6,000 miles (10,000 km) per year –
should, nevertheless have their oil
changed every 2 years at the most, no
matter what the Service Interval Display
indicates, since engine oil breaks down
over time, regardless of use. Service and Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet (Cana-
dian models)For additional information on required
maintenance intervals and procedures,
please refer to the Service and Warranty Information Booklet
(US models), or the Warranty and
Service Guide Booklet (Canadian
models).
As a precaution against rust, it is advis-
able to have the body checked for
damage from rocks or gravel at the
same time, depending upon operating
conditions.
Have your BMW center perform
maintenance and repair.
Your BMW center is always informed on
the latest maintenance work and repair
techniques and equipped with the
required special tools. In addition,
checking parts known from experience
to be subject to wear is a permanent
part of the maintenance specifications.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet (US models), or in
the Warranty and Service Guide
Booklet (Canadian models). These
entries are your verification for the
regular maintenance of your vehicle
and are required for the performance of
warranty repairs.<
