Engine Oil
34611-6. Engine Oil■Engine Oil ConsumptionSome engine oil will be consumed while
driving. The rate of consumption can be
affected by such factors as transmission
type, driving style, terrain and tempera-
ture. Under the followi ng 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)
 When the engine is operated at high
engine speeds (for extended periods of
time)
 When the engine is operated under
heavy loads (for extended periods of time)
 When the engine idles for extended
periods of time
 When the vehicle is operated in stop
and go and/or heavy traffic situations
 When the vehicle is used under severe
thermal conditions
 When the vehicle accelerates and
decelerates frequently
Under these or similar conditions, you
should check your oil at least every 2nd
fuel fill-up and change your engine oil
more frequently. Different drivers in the
same car may experience different
results. If your oil consumption rate is
greater than expected, contact your
authorized SUBARU retailer who may
perform a test under controlled conditions.
■ Checking the Oil Level1. Park the vehicle on a level surface and
stop the engine. If you check the oil level
just after stopping the engine, wait for at least 5 minutes for the oil to drain back into

the oil pan before checking the level.
1) Oil level gauge
2) Oil filler cap
3) Oil filter2. Pull out the level gauge, wipe it clean,
and insert it again.
3. Be sure the level gauge is correctly
inserted until it stops.
CAUTION
 If the level gauge is not pulled out
easily, twist the level gauge right
and left, then pull it out. Other-
wise, you may be injured acciden-
tally straining yourself. Use only engine oil with the
recommended grade and
viscosity. Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.
CAUTION
If the level gauge cannot be pulled
out easily, twist the level gauge
right and left, then gently pull it out.
Otherwise, you may be injured acci-
dentally straining yourself.

Differential Gear Oil
353
Maintenance and Service11
– CONTINUED –
11-12. Differential Gear OilIt is not necessary to check the gear oil
level. Check that there are no cracks,
damage or leakage. However, the oil
inspection should be performed according
to the maintenance schedule in the
“Warranty and Maintenance Booklet”.
Consult your SUBARU dealer for details.■ Recommended Grade and
ViscosityEach oil manufacturer has its own base
oils and additives. Never use different
brands together. For details, refer to
"Manual Transmission and Differential
Gear Oil" P383.
11-13. Manual Transmission OilIt is not necessary to check the transmis-
sion oil level. Check that there are no
cracks, damage or leakage. However,
have the oil inspected by your SUBARU
dealer according to the maintenance
schedule in the “Warranty and Mainte-
nance Booklet”. Consult your SUBARU
dealer for details.■ Recommended Grade and
ViscosityEach oil manufacturer has its own base
oils and additives. Never use different
brands together. For details, refer to
"Manual Transmission and Differential
Gear Oil" P383.
11-14. Brake Fluid■ Checking the Fluid Level
CAUTION
Using a differential gear oil other
than the specified oil may cause a
decline in vehicle performance.
WARNING
 Never let brake fluid contact your
eyes because brake fluid can be
harmful to your eyes. If brake
fluid gets in your eyes, immedi-
ately flush them thoroughly with
clean water. Fo r safety, when
performing this work, wearing
eye protection is advisable. Brake fluid absorbs moisture
from the air. Any absorbed mois-
ture can cause a dangerous loss
of braking performance. If the vehicle requires frequent
refilling, there may be a leak. If
you suspect a problem, have the
vehicle checked at your SUBARU
dealer.
CAUTION
 When adding brake fluid, be
careful not to allow any dirt into
the reservoir. Never splash the brake fluid over
painted surfaces or rubber parts.
Alcohol contained in the brake
fluid may damage them.

■Manual Transmission and Differential Gear Oil*1: The indicated oil quantity is only a guideline. The necessary quantity for replacement may differ slightly depending on the temperature and other
factors. After refilling the gearbox wi th oil, the oil level should be checked.
*2: For more details about maintenance and service, refer to the indicated section.
*3: The vehicle is filled at the factory.
*4: This type of manual transmission oil can be used. However, using this type of oil will increase fuel consumption.
If oil other than “Manual Transmission Gear Oil LV 75W” is used, the following may be experienced:
 The overall performance and function of the transmission may be adversely affected.
 Rattling noises may occur during id ling and fuel consumption may increase.
Never use different brands together.
*5: Using a differential gear oil other than “D ifferential Gear Oil LX” may cause noise, vibrations and increased fuel consumpti on. Never use different
brands together.■ Fluids
