When to Change
Engine
Oil
If any one
of
these is true for you, use the short tripkity
maintenance schedule:
a
a
a
a
a
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).
You
operate your vehicle
in
dusty areas or
off-road frequently.
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.
If
none
of
them is true, use the long trip/highway
maintenance schedule. Change the oil and filter every
7,500
miles
(1
2
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.
