Engine Oil

PERIODIC MAINTENANCE SERVICES

3. Engine Oil

A: REPLACEMENT

1) Open the engine oil filter cap for quick draining of
the engine oil.
• 2.5 L model

• 3.0 L model

2) Drain the engine oil by removing the engine oil
drain plug.

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.

NOTE:
Prepare the container for draining of engine oil.
• 2.5 L model

• 3.0 L model

3) Replace the drain plug gasket with a new part.

4) Tighten the engine oil drain plug after draining
the engine oil.

Tightening torque:

44 N·m (4.5 kgf-m, 33 ft-lb)

• 2.5 L model

• 3.0 L model

5) Using engine oil of proper quality and viscosity,
fill engine oil to the F line on oil level gauge. Place
the vehicle on a level surface when checking oil
level.

Recommended oil:

Refer to RM section. <Ref. to RM-2, LUBRI-
CANTS, RECOMMENDED MATERIALS, Rec-
ommended Materials.>

NOTE:
The proper viscosity oil helps the engine maintain
its ideal temperature, and cranking speed in-
creased by reducing viscosity friction in hot condi-
tion.

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

NOTE:
• If the vehicle is used in regions of high tempera-
tures or in other severe environments, use oil with
the viscosities shown below.
• API standard: SM or SL
• SAE viscosity No.: 30, 40, 10W-50, 20W-40,
20W-50
6) Close the engine oil filler cap.
7) Start the engine, and spreads the oil in engine
room.
8) Stop the engine to inspect the oil level again. If
necessary, add engine oil up to the F line on the
level gauge. <Ref. to PM-11, INSPECTION, En-
gine Oil.>

B: INSPECTION

1) Park the vehicle on a level surface.
2) Remove the oil level gauge and wipe it clean.
3) Reinsert the level gauge all the way. Be sure that
the level gauge is correctly inserted and in the
proper orientation.
4) Remove the level gauge again and check the oil
level. If the engine oil level is below “L” line, make
sure that there is no oil leakage from the engine
section, then add oil to rise the level up to the “F”
line.
• 2.5 L model

• 3.0 L model

5) Start the engine and warm it up for a time.

6) After turning off the engine, wait a few minutes
for the oil to return to the oil pan before checking
the level.

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.

NOTE:
• Just after driving or while the engine is warm, en-
gine oil level may show in the range between the
“F” line and the notch mark. This is caused by ther-
mal expansion of engine oil. (2.5 L model)
• To prevent overfilling the engine oil, do not add
oil above the “F” line when the engine is cold.
• As the oil level gauge is used for daily inspection,
standard of F line and L line of the oil level gauge is
set for the condition that engine is cold.
