4) Fill engine oil through level gauge up to the cen-
ter between upper level and lower level. Place the
vehicle on a level surface when checking oil level.
Use engine oil of proper quality and viscosity, se-
lected in accordance with following.
Recommended oil:
Refer to "RM" section. <Ref. to RM-3, LUBRI-
CANTS, RECOMMENDED MATERIALS, Rec-
ommended Materials.>
Engine oil capacity
Except for 3.0 L model
Upper level:
Approx. 4.0 2 (4.2 US qt, 3.5 Imp qt)
Lower level:
Approx. 3.0 2 (3.2 US qt, 2.6 Imp qt)
3.0 L model
Upper level:
Approx. 5.5 2 (5.8 US qt, 4.8 Imp qt)
Lower level:
Approx. 4.5 2 (4.8 US qt, 4.0 Imp qt)
The proper viscosity oil make the engine ideal tem-
perature, and cranking speed increased by reduc-
ing viscaus friction in hot condition.
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
classification: SL, SJ or SH
SAE Viscosity No.: 30, 40, 10W-50, 20W-40, 20W-
50.
5) Close the engine oil filler cap.
6) Start the engine and warm it up for a time.
7) After the engine stops, recheck the oil level.

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 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 engine oil.
7) To prevent overfilling the engine oil, do not add
oil above the "F" line when the engine is cold.
