Engine Oil Service

With the introduction of synthetic oil
and extended oil change intervals, a
new oil filter with improved filter paper
design was introduced. The new filter
paper resists deterioration caused by
high oil temperatures over an extended
time.

Note:

Early style oil filter numbers with BMW
part numbers 11 42 1 427 908 or 11 42
1 745 390 should not be used in the
1999 and later BMW models.

Use any synthetic low viscosity oil to
top off the engine oil level between oil
changes, as long as it meets the API
classification SH. Castrol is now the
supplier of both the mineral based oil
used in earlier models and the
synthetic based oil used from model
year 1999.

BMW is constantly upgrading
recommended maintenance
procedures and requirements. The
information contained here is as
accurate as possible at the time of

publication. If there is any doubt
about what procedures apply to a
specific model or model year, or
what intervals should be followed,
remember that an authorized BMW
dealer has the latest information
on factory-recommended
maintenance.

Engine oil, checking level

Engine oil level is checked with a
dipstick (arrow) in engine block.

Check oil level with car on a level
surface, after engine has been
stopped for at least a few minutes.

Check level by pulling out dipstick
and wiping it clean. Reinsert it all
way and withdraw it again.

Oil level is correct if it is between
two marks near end of stick.

Add oil through filler cap (arrow) on
top of cylinder head. Add only amount
needed to bring oil level to MAX mark
on dipstick, using an oil of correct
viscosity and grade. Too much oil can
be just as harmful as too little.

Engine oil and filter, changing

A complete oil change requires new oil,
a new oil filter insert kit, and a new
drain plug sealing washer. The tools
needed, a 17 mm drain plug socket or
box wrench and a drain pan (8 - 10 US

qt. capacity), are described in

010

General

.

Note:

If using a "fast-lube" service facility for
oil changes, make sure the technician
hand-starts and torques the engine oil
drain plug using hand-tools. Power
tools can strip the threads of the plug
and the oil pan.

-

Run engine for a few minutes to
warm engine oil. Shut engine off.

-

With car on level ground, place
drain pan under oil drain plug.

Using a 36 mm wrench, loosen and
remove oil filter housing cover (arrow).
Remove filter cartridge and discard any
O-rings.

On Coupe or Convertible model:
Remove oil drain plug access panel in
center of front end reinforcement plate
below engine.

Using a socket or box wrench, loosen
drain plug at oil drain pan. Remove
plug by hand and let oil drain into pan.

CAUTION!

Pull the loose plug away from the
hole quickly to avoid being scalded
by hot oil. It will run out quickly
when the plug is removed. If
possible, use gloves to protect your
hands.

-

When oil flow has diminished to
an occasional drip, reinstall drain
plug with a new metal sealing
washer and torque plug.
