Engine Oil: Replacement

WARNING: This page is about a different variant/trim than selected.
  1. Drain engine oil by loosening engine oil drain plug.

  2. Open engine oil filler cap for quick draining of the engine oil.

  3. Replace drain plug gasket.
  4. Tighten engine oil drain plug after draining engine oil.
    1. Tightening torque:  44 N.m (4.5 kgf-m, 33 ft-lb)

  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 

    1. API classification 
    2. SJ or SH with the words "Energy Conserving or Energy conserving II", CCMC specification G4 or G5, ACEA specification A1, A2 or A3, or New API mark displayed on the container (If it is impossible to get SJ or SH grade, you may use SG grade). 

    Engine oil capacity (excludes oil filter): 

    1. Upper level:  5.5 l (5.8 US qt, 4.8 Imp qt)
    2. Lower level:  4.5 l (4.8 US qt, 4.0 Imp qt)

    G02113473

    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. 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: API classification: SJ or SH
    1. 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.
  8. After engine stops, recheck the oil level. If necessary, add engine oil up to upper level on level gauge.
