11-10 Maintenance and service/Cooling system
NOTE & Synthetic oil
. Changing the engine oil and oil filter
should be performed by a well-trained
expert. Contact your SUBARU dealer
for changing the engine oil and oil filter.
Fully trained mechanics are on standby
at a SUBARU dealer to utilize the
special tools, spare parts and recom-
mended oil for this work, and also, used
oils are properly disposed of.
. If performing oil replacement your-
self, observe the local regulations and
dispose of waste oil properly. You should use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using syn-
thetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner’s Manual. Refer to “Engine
oil” F12-4. Also, you must follow the oil
and filter changing intervals shown in the
Warranty and Maintenance booklet.
& Recommended grade and
viscosity
S11AE03
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
Refer to “Engine oil” F12-4.
NOTE
Engine oil viscosity (thickness) affects
fuel economy. Oils of lower viscosity
provide better fuel economy. However,
in hot weather, oil of higher viscosity is
required to properly lubricate the en-
gine.
S11AE05
NOTE
Synthetic oil of the grade and viscosity
noted in chapter 12 is the recom-
mended engine oil for optimum engine
performance. Conventional oil may be
used if synthetic oil is unavailable.

& Safety precautions

WARNING
Never attempt to remove the radiator
cap until the engine has been shut
off and has cooled down completely.
Since the coolant is under pressure,
you may suffer serious burns from a
spray of boiling hot coolant when
the cap is removed.
CAUTION
. Vehicles are filled at the factory
with SUBARU Super Coolant that
does not require the first change
for 11 years/137,500 miles (11
years/220,000 km). This coolant
should not be mixed with any
other brand or type of coolant
during this period. Mixing with a
different coolant will reduce the
life of the coolant. Should it be
necessary to top up the coolant
for any reason, use only SUBARU
Super Coolant.
If the SUBARU Super Coolant is
diluted with another brand or
