Maintenance and service/Engine oil

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.
