Fill engine oil through the filler pipe up to center between upper level 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 standard SL with the "Energy Conserving" logo is printed (if you cannot obtain the oil with SL grade, you may use SJ grade "ENERGY CONSERVING" oil.)

ILSAC standard, GF3 or new API certification mark (Star burst mark) label is on the container.

Engine oil capacity:

Upper level

Approx. 4.0 ohm (4.2 US qt, 3.5 lmp qt)

Lower level

Approx. 3.0 ohm (3.2 US qt, 2.6 lmp 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 API standard 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 standard: SL or SJ.
  
  ILSAC standard: GF-3.
  
  SAE Viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50
Close the engine oil filler cap.
Start the engine and warm it up for a time.
After the engine stops, recheck the oil level. < Ref. to INSPECTION , Engine Oil. >
