Engine oil

NOTE
For models except STI, when the
engine low oil level warning indicator
appears, have your vehicle inspected
by your SUBARU dealer as soon as
possible.

Engine oil consumption

Some engine oil will be consumed while
driving. 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
. When the engine is operated at high
engine speeds
. When the engine is operated under
heavy loads
. When the engine idles for long 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. If your oil consumption
rate is greater than 1 quart every 1,200
miles or 1 liter every 2,000 kilometers,
contact your SUBARU dealer who may
perform a test under controlled conditions.

Checking the oil level

Check the engine oil level at each fuel
stop.
1. Park the vehicle on a level surface and
stop the engine. If you check the oil level
just after stopping the engine, wait a few
minutes for the oil to drain back into the oil
pan before checking the level.
