Oil
Additives
Don’t add anything to your oil. Your Aurora retailer is
ready to advise
if
you
think something should be added.
When
to
Change
Engine
Oil
If
any one of these is true for you, use the short trip/city
maintenance schedule:
0

Most trips are less than
5
to
10
miles
(8
to
16
km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such
as
frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner.
If
any one of these is true for your
vehicle, then you need
to
change your oil and filter
every
3,000
miles
(5
000
km) or
3
months
--
whichever
occurs first. (See “Change Oil Message’’ in the Index.)
If
the CHANGE
OIL
NOW
message appears in the Driver
Information Center, you should change your oil.
If none of them is
true,
use the long triphighway
maintenance schedule. Change the oil and filter every
7,500
miles
(
12
500
km)
or
12
months
--
whichever
occurs first. Driving a vehicle with a
fully
warmed
engine under highway conditions causes engine oil to
break down slower.
(See “Change Oil Message” in the Index.) Always reset
the
engine oil life
to
100%
after every oil change.
