Engine Oil Change Intervals
CAUTION
Changing the engine oil and
filter requires special skills, tools
and equipment.
It is recommended that you
have your dealer perform this
service.
Before attempting any service
procedure yourself, make sure
that you are very familiar with it
and that you are confident you
can complete it safely.
Otherwise, you could be
injured or your vehicle could be
damaged.
CAUTION
Make sure you dispose of mate-
rials in accordance with envi-
ronmental protection
regulations to help protect the
environment and your health.
Engine oil loses its ability to lubri-
cate when contaminated. Be sure
to change your engine oil accord-
ing to the maintenance schedule.
Be sure to replace the engine oil
filter each time you change engine
oil.
Under severe conditions, change
the oil and oil filter more frequent-
ly than is recommended in the
standard maintenance schedule.
