Engine Oil: Service and Repair

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 engine oil.

Tightening torque: 44 Nm (4.5 kgf-m, 33 ft. lbs.) 

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 accordance with the table in figure.
Recommended oil ILSAC OF-3, which can be identified with the new API certification mark (Star burst mark) API classification SL with the
words "ENERGY CONSERVING" (if you cannot obtain 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 engine oil): Approximately 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.

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. designated by SUBARU.

NOTE:  If vehicle is used in desert areas with very high temperatures or for other heavy duty applications, the following viscosity oils may be
used: ILSAC classification: GF-3 or API classification: SLSAE 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.
