Changing Engine Oil And Filter - Porsche 944 Driver Manual

Changing Engine Oil
and Filter
High quality-multi-grade oils are suitable for all
year round driving. Seasonal oil changes are
therefore not necessary. Only if multi-grade
oils are not readily available, a single-grade oil
of the correct viscosity can be used.
Specifications of the various oils to be used
are detailed under "Filling Capacities and
Engine Oil". The use of oil additives is not
recommended by Porsche.
The oil filter should be changed at the inter-
vals listed in your Maintenance Schedule.
1. Unscrew the oil drain plug (arrow), remove
the oil filler cap and allow oil to drain
completely.
2. Loosen oil filter element with appropriate
wrench and remove.
3. Lightly coat new filter seal with engine oil.
4. Screw on filter by hand until gasket
contacts, tighten by one further turn and
finally recheck tightness of filter with the oil
filter wrench.
Specified tightening torque:
20 Nm (14 ftlb).
5. Clean oil drain plug. Always use a new
gasket when reinstalling the plug. Do not
overtighten the plug. Correct tightening
torque is 43 ft. Ib. or 60 Nm.
6. Fill the crankcase with the required amount
of engine oil labeled "API Service SE or SF"
(see "Filling Capacities"). Do not overfill.
7. Check oil level with dipstick. Top up if
necessary. Reinstall oil filler cap and tighten
securely.
8. Run the engine at various speeds for 3-5
minutes and check for leaks.

WARNING
When removing oil drain plug with your
fingers, keep your arms as high as
possible. This will prevent hot oil from
running down your arm. Wear eye
protection.
Always use a new gasket when
reinstalling the plug. Do not overtighten
the plug.
Before changing the engine oil yourself,
make sure that the disposal of the engine
oil and the oil filter, as special wastes, can
be carried out in the proper manner. Under
absolutely no circumstance should used
oil find its way into the sewage system,
soil, rivers, ponds, or other
environmentally damaging areas. If there is
no possibility of disposing of used oil in
the proper manner
(when in doubt, consult local authorities),
please have the oil changed by your dealer
or a service station.
Oil change intervals specified in the Warranty
& Maintenance booklet accompanying the
vehicle apply to normal operating conditions
and must be adhered to, including intervals for
oil filter change.
If you drive mostly short distances, or if you
operate the vehicle in dusty areas, or under
predominantly stop-and-go traffic conditions,
or when temperatures remain below freezing
for extended periods, the engine oil should be
changed more frequently.
When changing the engine oil and the oil filter,
the splash shield under the car has to be
removed first.
Drain the oil when the engine is still warm.
