All 2005 BMW X3s are factory-filled with
BMW High Performance Synthetic oils. At the
time of the printing of this booklet, the
following oils are strongly recommended
and approved by BMW:
• BMW High Performance 5W-30 Synthetic
Oil (BMW part number 07 51 0 017 866)
• Mobil 1 5W-30
• Mobil 1 5W-40
BMW is evaluating various synthetic oils for
inclusion in our list of recommended motor
oils. For the most current list of synthetic oils,
please contact your authorized BMW SAV
center, or call BMW of North America at 1-
800-831-1117. You can also obtain this
information from our website,
www.bmwusa.com.
It is recommended to check engine oil level
whenever fuel is added to the vehicle.
If you need to add oil between oil changes
and are unable to obtain BMW High
Performance Synthetic Oil, Mobil 1 or
another special oil on the list, use a syn-
thetic oil with an API rating of SJ or higher.
– Inspection I: Major vehicle maintenance
as specified in the following pages under
Inspection I.
– Inspection II: Additional major vehicle
maintenance as specified in the following
pages under Inspection II.The following maintenance elements must
be performed at the mileage/time stated
(time intervals begin from the vehicle’s
production date):
– Brake Fluid Service: Change brake fluid
every two years.
– Oxygen Sensor Service: The oxygen sensor
deteriorates strictly on a mileage basis and
must therefore be replaced every 100,000
miles to maximize vehicle fuel economy
and minimize exhaust pollution. The
replacement of the oxygen sensor is
required under the terms of the applicable
BMW emission system warranties.
– Spark Plug Service: The X3 is equipped
with platinum-tipped spark plugs. These
allow a longer service life than conven-
tional plugs. Replace spark plugs every
100,000 miles.
– Automatic Transmission Service: Change
ATF every 100,000 miles.
The engine coolant has a lifetime rating and
does not need to be changed.
Please see your authorized BMW SAV center
for the most current information.
For your convenience, you may also wish to
have your authorized BMW SAV center
perform any necessary operations to fulfill any
state inspection requirements in your area
concurrent with the maintenance elements
specified above during other repairs.
Make sure that confirmation of maintenance
work is always entered in this SAV Service and
Warranty Information Booklet. You may need
this for any warranty claims that become
necessary, and later on as evidence that your
SAV has been given the correct and regular
maintenance that justifies its resale or trade-in
value.
BMW has applied the most modern techno-
logical advances not only to the design and
production of your SAV, but also to computing
of the optimum maintenance interval for your
type of operations and driving style. Your
authorized BMW SAV center has made a
