Lower the vehicle.
Select engine oil of adequate quality and viscosity and fill it through the oil filler duct to the "F" line on the oil level gauge. Make sure that the vehicle is parked on a level surface when checking oil level.
Recommended oil:

Refer to the "Recommended Material" information for the recommended oil. < Ref. to LUBRICANTS , RECOMMENDED MATERIALS, Recommended Materials. >

Engine oil capacity:

CAUTION: It is acceptable to fill an engine with oil of another brand when replacing the oil, but make sure to use an oil with an API standard and SAE viscosity number specified by Subaru.

NOTE: The proper viscosity oil helps the engine maintain its ideal temperature, and cranking speed increased by reducing viscosity friction in hot condition.
Close the oil filler cap.
Start the engine to circulate the oil in engine room.
After stopping the engine, recheck the oil level.
