Engine Oil
7) Fill engine oil through the filler pipe up to center
between upper lever and lower level. Make sure
that the vehicle is placed level when checking oil
level. Use engine oil of proper quality and viscosity,
selected in accordance with the table in figure.
Recommended oil
API classification SL, SJ with the “Energy
Conserving” logo is printed, or SH (if you
cannot obtain the oil with SL, SJ or SH
grades, you may use SG, SF grades “ENER-
GY CONSERVING” oil.)
ACEA specification, A1, A2 or A3
CCMC specification, G4 or G5
New API certification mark (Star burst mark)
label is on the container.
Engine oil capacity
Upper level
Approx. 4.02 (4.2 US qt, 3.5 Imp qt)
Lower level
Approx. 3.02 (3.2 US qt, 2.6 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 API
classification and SAE viscosity No. designat-
ed by SUBARU.
NOTE:
If the vehicle is used in areas with very high temper-
atures or for other heavy duty applications, the fol-
lowing viscosity oils may be used: API
classification: SL, SJ or SH
SAE Viscosity No. : 30, 40, 10W-50, 20W-40, 20W-
50.
8) Close the engine oil filler cap.
9) Start the engine and warm it up for a time.
10) After the engine stops, recheck the oil level.
B: INSPECTION
1) Park the vehicle on a level surface.
2) Remove the 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 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.

4) Wipe clean the oil filter matching surface on cyl-
inder block or oil cooler.
5) Get a new engine oil filter and apply a thin coat of
engine oil to the seal rubber.
CAUTION:
Be careful not to use the oil filter 80 mm (3.15 in)
in diameter to turbo model.6) Install the oil filter by turning it by hand, being
careful not to damage the seal rubber.
Tighten the oil filter 80 mm (3.15 in) or 65 mm
(2.56 in) in diameter by approx. 2/3 — 3/4 rotation
more after the seal rubber of oil filter comes in con-
tact with cylinder block or oil cooler.
Tighten the oil filter 68 mm (2.68 in) in diameter
by approx. 1 rotation more after the seal rubber of
oil filter comes in contact with cylinder block or oil
cooler.
CAUTION:
Do not tighten excessively, or oil may leak.
7) After installing the oil filter, run the engine and
make sure that no oil is leaking around seal rubber.
NOTE:
The filter element and filter case are permanently
joined; therefore, interior cleaning is not necessary.
8) Check the engine oil level.
