PERIODIC MAINTENANCE SERVICES
NOTE:
1.This inspection is not required to maintain emission warranty eligibility and it dose not affect the manufacturer’s obligations under
EPA’s in-use compliance program.
2.When the vehicle is used in extremely dusty conditions, the air cleaner element should be replaced more often.
3.A tire should be replaced when the tread wear indicator appears as a solid band across the tread. The indicators appear when the
remaining tread has been worn to 1.6 mm (0.063 in) or less.
4.When the vehicle is used under extremely dusty conditions, the A/C filter should be replaced more often.
5. Replace the first time after 11 years or every 220,000 km (137,500 miles), and thereafter every six years or every 120,000 km
(75,000 miles).
6.When the vehicle is used under severe condition such as towing trailer or driving on sand, ATF, differential gear oil (both front and
rear) and transmission gear oil should be replaced more often.

Engine Oil
PERIODIC MAINTENANCE SERVICES
3. Engine Oil
A: REPLACEMENT
1) Set the vehicle on a lift.
2) Open the engine oil filter cap for quick draining of
engine oil.
CAUTION:
If any engine oil is spilled on the exhaust pipe,
under cover, wipe off completely to prevent
fires or emission of smoke.
3) Lift up the vehicle.
4) Drain engine oil by loosening the engine oil drain
plug.
NOTE:
Prepare the container for draining of engine oil.
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, LUBRICANT, RECOM-
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: SN, SM, or SL
ILSAC standard: GF-4 or GF-5
SAE viscosity No.: 30, 40, 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.
<Ref. to PM-5, INSPECTION, Engine Oil.>
B: INSPECTION
CAUTION:
If any engine oil is spilled on the exhaust pipe,
under cover, wipe off completely to prevent
fires or emission of smoke.
1) Park the vehicle on a level surface.
2) Remove the oil level gauge and wipe it clean.
3) Reinsert the oil level gauge all the way. Be sure
that the oil level gauge is correctly inserted and
properly orientated.
4) Remove the level gauge again and record the oil
level. If the engine oil level is below the “L” line, add
oil to bring the level up to but not over the “F” line.
5) Start the engine and warm it up for a time.
