3 Your BMW is factory-equipped with a
newly-developed synthetic engine oil. At
the time of the printing of this booklet BMW
High-Performance Synthetic 5W-30 Oil
(Part Number 07 51 0 017 866) and Mobil 1
5W-30 and 5W-40 oils are strongly
recommended and approved by BMW for
the BMW Z4 models. BMW is evaluating
various synthetic oils for inclusion in our list
of recommended motor oils.
It is recommended to check engine oil level
whenever fuel is added to the vehicle.
– 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 appli-
cable BMW emission system warranties.
– Spark Plug Service: 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.For your convenience, you may also wish to
have your BMW 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 Service and
Warranty Information Statement. You may need
this for any warranty claims that become
necessary, and later on as evidence that your
car has been given the correct and regular
maintenance that justifies its resale or trade-in
value.
BMW has applied the most modern
technological advances not only to the design
and production of your vehicle, but also to
computing of the optimum maintenance
interval for your type of operations and driving
style. Your BMW center has made a substantial
investment in unique BMW special service
tools to enable his BMW factory trained service
technicians to perform quality repairs on your
BMW in minimal time. He/she looks forward to
serving your every service need and to help
maximize your satisfaction with your BMW, its
longevity, and resale value.
