■Adding engine oil
If the oil level is below or near
the low level mark, add engine
oil of the same type as already in
the engine.
Make sure to check the oil type and prepare the items needed before
adding oil.
Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise.

■Engine oil consumption
Some engine oil will be consumed while driving. The rate of consumption
can be affected by such factors as transmission type, driving style, terrain
and temperature. Under the following conditions, oil consumption can be
increased and thus require refilling between maintenance intervals:
●When the engine is new and within the break-in period
●When the engine oil is of lower quality
●When the incorrect oil viscosity is used
●When engine braking is employed (repeatedly)

Lubrication system
*: The engine oil capacity is a reference quantity to be used when changing
the engine oil. Warm up and turn off the engine, wait more than 5 minutes,
and check the oil level on the dipstick.
■Engine oil selection
Always use SUBARU approved engine oil. For details, we recom-
mend that you contact your SUBARU dealer.
If approved engine oil is unavailable, another motor oil of matching
quality can also be used.
Oil grade:
ILSAC GF5 multigrade engine oil
API classification SN with the words “RESOURCE CONSERVING”
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.

Vehicle specifications
Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allows
cold startability. Oils with a lower value before the W allow for easier
starting of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil when
the oil is at high temperature. An oil with a higher viscosity (one with a
higher value) may be better suited if the vehicle is operated at high
speeds, or under extreme load conditions.
How to read oil container labels:
Either or both API registered marks are added to some oil containers
to help you select the oil you should use.
API Service Symbol
Top portion: The oil quality desig-
nation by API (American Petro-
leum Institute) (SN)
Center portion: The SAE viscosity
grade (SAE 0W-20)
Lower portion: “RESOURCE
CONSERVING” means that the
oil has fuel saving and environ-
mental protection capabilities.
ILSAC Certification Mark
The ILSAC (International Lubri-
cant Specification Advisory Com-
mittee) Certification Mark is
displayed on the front of the con-
tainer.

CAUTION
■Differential gear oil
Using a differential gear oil other than Differential Gear Oil LX may cause
occurrences of rattling noises while idling and poor fuel consumption.
Never use different brands together.

■Manual transmission gear oil
If oil other than “MG Gear Oil special II” is used, the following may be experi-
enced:
●The overall performance and function of the transmission may be
adversely affected.
●Rattling noises may occur during idling and fuel consumption may
increase.
