2002 BMW Z8 engine oil

112n
Engine oil Specified engine oilThe quality of the engine oil is
extremely important for the function
and life of an engine. Based on exten-
sive testing, BMW has approved only
certain types of engine oils.
Use only approved "BMW High Perfor-
mance Synthetic Oil."
If you are unable to obtain "BMW High
Performance Synthetic Oil," you can
add small amounts of synthetic oil in
between oil changes. Use only oils with
API SH specification or higher.
Ask your BMW center for details
concerning the specific "BMW
High Performance Synthetic Oil" or
"synthetic oils" that have been
approved.<
You can also call BMW of North
America at 1-800-831-1117 or visit this
website: www.bmwusa.com for more
detailed information.
Viscosity ratings Viscosity is the oilflow rating as estab-
lished in SAE classes.
Select the correct SAE class based on
the climatic conditions in the area
where you typically drive your BMW Z8
roadster.
Approved oils are SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.

Engine oil Coolant
Comply with the applicable envi-
ronmental laws regulating the
disposal of used oil.<
Recommendation: have the oil changed
by your BMW center only.
Continuous exposure to used oil
has caused cancer in laboratory
testing.
For this reason, thoroughly wash any
areas of skin that come into contact
with oil using soap and water.
Always store oils, grease, etc. so that
they are inaccessible to children, and
follow warning lables on containers.<
Do not add coolant to the coolant
system when the engine is hot,
since escaping coolant can cause
burns.
To avoid the possibility of damage later
on, never use anything other than
factory-approved, nitrite- and amino-
free, extended-duty antifreeze with
corrosion inhibitor. Your BMW center is
familiar with the official specifications.
Antifreeze and corrosion inhibitor is
hazardous to health. Always store in
tightly closed original containers kept
well out of the reach of children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethyleneÐglycol: never allow
the antifreeze to spill onto hot engine
components, as fire and serious
personal injury in the form of burns
could result.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<
Checking coolant levelThe correct coolant level when the
engine is cold (approx. 687/206):
Up to the "MAX" mark on the translu-
cent expansion tank.520de156

The BMW Maintenance System has
been designed as a reliable means of
ensuring that our customers enjoy
optimal vehicle safety and reliability
with only minimum effort and expense.
Please keep in mind that regular service
not only plays a vital role in ensuring
continued vehicle safety, but also plays
a significant role in maintaining your
vehicle's resale value.

Service Interval DisplayOptimal maintenance intervals are
calculated by using advanced tech-
nology; these then are indicated in the
Service Interval Display. While conven-
tional systems rely on distance traveled
alone to determine when service is due,
the BMW Maintenance System has for
years considered the actual conditions
under which the vehicle operates,
because miles can be traveled in many
different ways:
From the maintenance point of view,
62,000 miles (100,000 km) accumulated
in short-distance urban driving are not
equivalent to the same distance
covered at moderate speeds in long-
distance highway travel.
The BMW Maintenance System, which
is based on operating conditions,
includes the Engine Oil Service and
Inspections I and II.
Determining the maintenance intervals
according to the actual loads on the
vehicle covers every kind of operating
situation. However, even those drivers
who put significantly less than
6,000 miles (10,000 km) on their vehicle
anually should have the engine oil
changed at least every two years since
oil deteriorates over time, regardless of
use.
Service Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet
(Canadian models)For additional information on mainte-
nance intervals and procedures, please
refer to the Service and Warranty Infor-
mation Booklet (US models) or the
Warranty and Service Guide Booklet
(Canadian models).
Have your BMW center perform
maintenance and repair work.
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 the
Warranty and Service Guide Booklet
(Canadian models).
These entries are your proof of regular
vehicle maintenance and the basis for
warranty claims.<

Vehicle storage
If the vehicle is to be stored for
more than three months, ensure
that the following service operations
are carried out first.<
Preparations for storageHave your BMW center perform the
following procedures:
1. Clean and apply a rust proofing
agent or other treatment to the
engine, engine compartment, under-
carriage, axles and major compo-
nents in accordance with approved
repair procedures. Wash the vehicle,
clean the interior and treat painted
and chromed parts. Clean the
weather-stripping around the hood,
luggage compartment and doors
2. Change engine oil and oil filter at
operating temperature. As an addi-
tional corrosion protection measure,
an anticorrosive agent can be added
to the engine in accordance with the
manufacturer's instructions
3. Check the coolant level and concen-
tration and top off if necessary
4. Check the fluid level of the wind-
shield washer fluid reservoir; top off
if necessary
5. Fill the fuel tank completely to
prevent the formation of condensa-
tion
6. Increase the tire inflation pressure to
51 psi (350 kPa).Before parking the vehicle1. Dry the parking brake and footbrake
by brake applications to prevent the
brake discs and drums from
corroding
2. Park the vehicle in a covered, dry,
and well-ventilated area. Place the
transmission in first gear or, if neces-
sary, chock the wheels to prevent the
vehicle from rolling. Do not engage
the parking brake
3. Remove the battery, charge it
completely and store it in a cool (but
frost-free) room
4. Remove the hardtop and store it
separately, refer to page 96
5. Close the convertible top.
During storageRecharge a battery that has been taken
out of the vehicle every six months. If it
is not recharged, it will not be service-
able. Every time the battery is
discharged, especially over extended
periods, its service life is reduced.Removing the vehicle from
storageRecharge the battery if the "Magic Eye"
turns black, refer to page 138.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement, if necessary. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).
