PERIODIC MAINTENANCE SERVICES
The proper viscosity helps vehicle get good cold
and hot starting by reducing viscous friction and
thus increasing cranking speed.
NOTE:
• 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 classification,
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 classification: SL
SAE Viscosity No.: 30, 40, 10W-50, 20W-40, 20W-
50
6) Close engine oil filler cap.
7) Start engine and warm it up for a time.
8) After engine stops, recheck the oil level.
If necessary, add engine oil up to upper level on
level gauge.

1) Park vehicle on a level surface.
2) Remove 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 it again and note the reading. If the en-
( E )
gine oil level is below the "L" line, add oil to bring
the level up to the "F" line.
( D )
5) After turning off the engine, wait a few minutes
for the oil to drain back into the oil pan before
checking the level.

6) 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 the engine oil.
7) To prevent overfilling the engine oil, do not add
oil above the "F" line when the engine is cold.
