best for your
vehicle. However, you can use SAE 1OW-30 if it's going
to be 0°F (-1
8'C)
or above. These numbers on
an
oil
container
show
its viscosity, or thickness.
Do
not use
other viscosity oils, such as SAE 2OW-50,

maintenance schedule:
0
Mos't trips
are
less
than
5 to 10 miles (8 to 14
k r n ) .
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

every 3,000 miles
(5
000
k r r a )
or 3 months
