ENGINE OIL

3. Engine Oil

A: INSPECTION

1) Park vehicle on a level surface.
2) Remove oil level gauge and wipe it clean.
3) Reinsert the level gauge all the way. Be sure that
the level gauge is correctly inserted and in the
proper orientation.
4) Remove it again and note the reading. If the en-
gine oil level is below the “L” line, add oil to bring
the level up to the “F” line.
5) After turning off the engine, wait a few minutes
for the oil to drain back into the oil pan before
checking the level.
6) Just after driving or while the engine is warm, en-
gine oil level may show in the range between the
“F” line and the notch mark. This is caused by ther-
mal expansion of the engine oil.
7) To prevent overfilling the engine oil, do not add
oil above the “F” line when the engine is cold.

B: REPLACEMENT

1) Open engine oil filler cap for quick draining of the
engine oil.
2) Drain engine oil by loosening engine oil drain
plug.

3) Replace drain plug gasket.
4) Tighten engine oil drain plug after draining en-
gine oil.

ENGINE OIL

5) Fill engine oil through filler pipe up to upper point
on level gauge. Make sure that vehicle is placed
level when checking oil level. Use engine oil of
proper quality and viscosity, selected in accor-
dance with the table in figure.

Recommended oil

ILSAC GF-3, which can be identified with
the new API certification mark (Star burst
mark)
API classification SL with the words “EN-
ERGY CONSERVING” (if you cannot ob-
tain the oil with SL grade, you may use SJ
grade “ENERGY CONSERVING” oil)
ACEA specification A1, A2 or A3

Oil amount for preparation (when replacing en-
gine oil):

Approx. 4.5

(4.8 US qt, 4.0 Imp qt)

The proper viscosity helps vehicle get good cold
and hot starting by reducing viscous friction and
thus increasing cranking speed.

CAUTION:
When replenishing oil, it does not matter if the
oil to be added is a different brand from that in
the engine; however, use oil having the ILSAC
or API classification and SAE viscosity No. des-
ignated by SUBARU.

NOTE:
If vehicle is used in desert areas with very high tem-
peratures or for other heavy duty applications, the
following viscosity oils may be used: ILSAC classi-
fication: GF-3 or API classification: SL
SAE Viscosity No.: 30, 40, 10W-50, 20W-40, 20W-
50.
6) Close engine oil filler cap.
7) Start engine and warm it up for a time.

8) After engine stops, recheck the oil level. If nec-
essary, add engine oil up to upper level on level
gauge.

16) Remove oil pump by using flat bladed screw-
driver.

CAUTION:
Be careful not to scratch mating surfaces of
cylinder block and oil pump.

B: INSTALLATION

Install in the reverse order of removal.
Do the following:
1) Apply fluid gasket to matching surfaces of oil
pump.
