11 - 1 0 Maintenance and service
If you check the oil level just after stopping
the engine, wait a few minutes for the oil to
drain back into the oil pan before checking
the level.
To prevent overfilling the engine oil, do not
add any additional oil above the upper lev-
el when the engine is cold.
In 2.5-liter-engine models, the dipstick has
a notch above the upper level.
Just after driving or while the engine is
warm, the engine oil level reading may be
in a range between the upper level and
the notch mark. This is caused by thermal
expansion of the engine oil. „Changing the oil and oil filter
Change the oil and oil filter according to
the maintenance schedule in the “Warran-
ty and Maintenance Booklet”.
The engine oil and oil filter must be
changed more frequently than listed in the
maintenance schedule when driving on
dusty roads, when short trips are frequent-
ly made, or when driving in extremely cold
whether.
1. Warm up the engine by letting the en-
gine idle for approximately 10 minutes to
ease draining the engine oil.
2. Park the vehicle on a level surface and
stop the engine. 3. Remove the oil filler cap.
2.5-liter models
3.0-liter models
4. Drain out the engine oil by removing the drain plug while the engine is still
warm. The used oil should be drained into
an appropriate container and disposed of
properly.
5. Wipe the seating surface of the drain
plug with a clean cloth and tighten it se-
curely with a new sealing washer after the
oil has completely drained out.

6. Open the access cover by removing
the clips and turning the access cover
counterclockwise. The oil filter will be ex-
posed. 2.5-liter models
3.0-liter models
7. Remove the oil filt er with an oil filter
wrench. 8. Before installing a new oil filter, apply a
thin coat of engine oil to the seal.
9. Clean the rubber seal seating area of
the bottom of engine an
d install the oil fil-
ter by hand turning. Be careful not to twist
or damage the seal.
10.Tighten the oil filter by the amount indi-
cated in the following table after the seal
makes contact with the bottom of engine.
11.Reinstall the cover under the oil filter.
12.Pour engine oil through the filler neck.

y Never over tighten the oil filter be-
cause that can result in an oil leak.
y Thoroughly wipe off any engine
oil that has spilled over the ex-
haust pipe and/or under-cover. If
left unremoved, the oil could
catch fire.

11 - 1 2 Maintenance and service
Oil capacity (Guideline):
2.5-liter models: 4.2 US qt (4.0 liters, 3.5 Imp qt)
3.0-liter models: 5.8 US qt (5.5 liters, 4.8
Imp qt)
The oil quantity indicated above is only a
guideline. The necessary quantity of oil
depends on the quantity of oil that has
been drained. The quantity of drained oil
differs slightly depen ding on the tempera-
ture of the oil and the time the oil is left
flowing out. After refilling the engine with
oil, therefore, you must use the dipstick to
confirm that the level is correct.
13.Start the engine and make sure that no
oil leaks appear around the filter’s rubber
seal and drain plug.
14.Run the engine until it reaches the nor-
mal operating temperature. Then stop the
engine and wait a few minutes to allow the
oil drain back. Check the oil level again
and if necessary, add more engine oil. „ Recommended grade and
viscosity
Oil grade:
ILSAC GF-4, which can be identified
with the ILSAC certification mark
(Starburst mark)
or API classification SM with the
words “ENERGY CONSERVING”
These recommended oil grades can be
identified by looking for either or both of
the following marks displayed on the oil
container.
ILSAC Certification Mark (Starburst Mark) API Service label
1) Indicates the oil quality by API designa-
tions
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving ca- pabilities
In choosing an oil, you want the proper
quality and viscosity, as well as one that
will add to fuel economy. The following ta-
ble lists the recommended viscosities and
applicable temperatures.
When adding oil, different brands may be
used together as long as they are the same API classifica tion and SAE viscosity
as those recommended by SUBARU.
Use only engine oil with the recom-
mended grade and viscosity.
