Minimum Octane Rating corresponds to the
Anti Knock Index AKI and is determined by the
so-called (R+M)/2 method.
Do not use leaded gasoline, as otherwise
the lambda probe and catalytic converter
will be permanently damaged.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10 % ethanol or other
oxygenates with up to 2.8 % oxygen by weight,
that is, 15 % MTBE or 3 % methanol plus an
equivalent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality
brand.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<

6.Return the dipstick to the guide tube,
inserting it as far as it will go.
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. 1.1 quarts/
1 liter.
Do not fill beyond the upper mark on the
dipstick. Excess oil will damage the
engine.<
Adding engine oil
Do not add oil until the oil level has dropped
almost to the lower mark on the dipstick, refer to
page86.
Add oil within the next 30 miles/50 km,
otherwise the engine could be dam-
aged.<
Continuous exposure to used oil has
caused cancer in laboratory tests. For this
reason, thoroughly wash any areas of skin that
come into contact with oil using soap and water.
Always store oils, grease and similar materials
so that they are inaccessible to children. Com-
ply with warning labels and the information on
the containers.<
Comply with the applicable environmen-
tal laws regulating the disposal of used
oil.<
Oil change
Have your oil changed only by a BMW center or
a workshop that works according to BMW
requirements with the appropriately trained
personnel.
Approved engine oils
The quality of the engine oil is extremely impor-
tant for the function and life of an engine. Based
on extensive testing, BMW has approved cer-
tain grades of engine oil.
Use approved High Performance Synthetic Oil.
If you are unable to obtain an approved High
Performance Synthetic Oil, you may use small
volumes of other synthetic oils for topping up
between oil changes. Use only oils with the
specification API SH or higher.
Ask your BMW center for details concern-
ing the specific High Performance Syn-
thetic Oil or synthetic oils that have been
approved.<
You can also call BMW of North America toll-
free at 1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this information.
BMW engines are designed to operate
without oil additives; the use of additives
could even lead to damage in some cases.<
Coolant
Warning lamp
The warning lamp lights up:
The coolant level is too low. Top up the
coolant as soon as possible.
Do not open the cooling system when the
engine is hot. If you do, escaping coolant
can cause burns.<
Coolant consists of water and coolant additives.
Not all commercially available additives are suit-
able for your BMW. Your BMW center knows
which additives are appropriate.
Use only approved additives, as the
engine could otherwise be damaged. The
additives are hazardous to health.<
Comply with the applicable environmen-
tal laws regulating the disposal of coolant
additives.<
