A: REPLACEMENT
1) Set the vehicle on a lift.
2) Open the engine oil filter cap for quick draining of
engine oil.
3) Lift up the vehicle.
4) Drain engine oil by loosening the engine oil drain
plug.
• Non-turbo model
• Turbo model
NOTE:
Prepare the container for draining of engine oil.
CAUTION:
If the engine oil is spilt over exhaust pipe or the
under cover, wipe it off with cloth to avoid emit-
ting smoke or causing a fire.
5) Replace the drain plug gasket.
NOTE:
Use a new drain plug gasket.
6) Tighten the engine oil drain plug after draining
engine oil.
Tightening torque:
44 N·m (4.5 kgf-m, 32.5 ft-lb)
7) 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 sur-
face when checking oil level.
Recommended oil:
Refer to “RM” section for the engine oil vis-
cosity. <Ref. to RM-2, LUBRICANTS, RECOM-
MENDED MATERIALS, Recommended
Materials.>
Engine oil capacity
Refer to “SPC” section for the engine oil ca-
pacity. <Ref. to SPC-4, CAPACITY, Impreza.>
NOTE:
• The proper viscosity helps vehicle get good cold
and hot starting by reducing viscous friction and
thus increasing cranking speed.
• When replenishing oil, it does not matter if the oil
to be added is a different brand from that in the en-
gine; 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: SM or SL
ILSAC standard: GF-4
SAE viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50
8) Close the engine oil filler cap.
9) Start the engine and warm it up for a time.
10) Stop the engine to inspect the oil level again.
