Checking the oil level

Adding engine oil

The oil volume between the two marks

on the dipstick corresponds to approx.

1.1 US quarts (1 liter). Do not fill beyond

the upper mark on the dipstick. Excess

oil will damage the engine.

1 Park the vehicle on a level surface

2 Shut the engine off after it has

reached normal operating tempera-

ture

Wait until the level has dropped to just

above the lower mark before adding oil.

However, do not wait until the oil drops

below the lower mark.

3 After approx. 5 minutes, pull the dip-

stick out and wipe it off with a clean

lint-free cloth, paper towel, or similar

material

BMW engines are designed to op-

erate without oil additives. The

use of additives could lead to damage

in some cases. This is also true for the

automatic transmission, the differential

and the power steering system.<

4 Push the dipstick carefully all the way

into the guide tube and pull it out

again

5 The oil level should be in between the

two graduations on the dipstick.

As with fuel economy, oil consumption

is directly influenced by your driving

style and vehicle operating conditions.

Engine oil specifications

Viscosity ratings

The quality of the engine oil selected

has critical significance for the opera-

tion and service life of an engine. Based

on extensive testing, BMW has ap-

proved only certain engine oils.

Viscosity is the oil flow rating as estab-

lished in SAE classes.

The selection of the correct SAE class

depends on the climatic conditions in

the area where you drive your BMW.

Use only approved "BMW High-Perfor-

mance Synthetic Oil."

Approved oils are in SAE classes

5W-40 and 5W-30.<

If you are unable to obtain "BMW High-

Performance Synthetic Oil," you can

add small amounts of synthetic oil in

between oil changes. Only use oils with

the API SH specification or higher.

These oils may be used for driving in all

ambient temperatures.

Ask your authorized BMW center

for details concerning the specific

"BMW High-Performance Synthetic Oil"

or other synthetic oils that have been

approved.

You can also call BMW of North

America at 1-800-831-1117, or visit this
