CAUTION: Be careful not to spill the engine oil on exhaust pipe to prevent it from emitting smoke or fire. When the oil is spilled on exhaust pipe, wipe it away with a shop cloth.
Replace drain plug gasket with a new one.
Tighten engine oil drain plug after draining engine oil.
Tightening torque:

44 N.m (4.5 kgf-m, 33 ft-lb)
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 accordance with the table in figure.
Engine oil amount for preparation:

Approx. 4.0 l (4.2 US qt, 3.5 Imp qt)

The proper viscosity helps vehicle get good cold and hot starting by reducing viscous friction and thus increasing cranking speed.
NOTE:
- 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. designated by SUBARU.
- If vehicle is used in desert areas with very high temperatures or for other heavy duty applications, the following viscosity oils may be used:
API classification: SM or SL

ILSAC classification: GF-4

SAE Viscosity No.: 30, 40,10W-50, 20W-40, 20W-50
Close engine oil filler cap.
Start engine and warm it up for a time.
After engine stops, recheck the oil level.
If necessary, add engine oil up to upper level on level gauge.
