  NOTE: Prepare the container for draining of engine oil.
  
  CAUTION: If any engine oil is spilled on the exhaust pipe, wipe off completely to prevent fires or emission of smoke.
Replace the drain plug gasket.
NOTE: Use a new drain plug gasket.
Tighten the engine oil drain plug after draining engine oil.

Using engine oil of proper quality and viscosity, fill engine oil through the oil filler duct to the "F" line on oil level gauge. Place the vehicle on a level surface when checking oil level.
Recommended oil

For engine oil viscosity, refer to LUBRICANTS , RECOMMENDED MATERIALS, Recommended Materials.

Engine oil capacity

Refer the engine oil capacity . Refer to CAPACITY , Forester.
NOTE:
- The vehicle will start well even when temperatures are low or high by increasing the cranking speed by reducing viscous friction for the appropriate viscosity.
- When replacing the oil, it is acceptable to use oil from a different manufacturer than the oil previously used. However, you must use an oil that matches the API standards and SAE viscosity specified by Subaru.
- It is acceptable to use oil having the viscosities described below if the vehicle is being used in desert locations or in excessive environments where temperatures are extremely high.
  API standard: SM or SL
  
  ILSAC standard: GF-4
  
  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.
Stop the engine to inspect the oil level again. Refer to INSPECTION , Engine Oil.
