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 2 (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.

essary, add engine oil up to upper level on level
gauge.
