Introduction
WARNING!
Handle lubricants carefully. Vehi-
cle lubricants (oil and grease) can
be poisonous and cause death, per-
sonal injury or sickness. They can
also damage the paint on the vehi-
cle.
In this section you will find the basic
information you need to do the routine
lubrication your vehicle requires. Of
course you will want to schedule
service more frequently if you are
operating under severe conditions
such as extreme heat or cold, with
very heavy loads, off-road, etc. For
any special service requirements,
consult your service manuals and your
lubricant supplier. Please remember:
one key to keeping your truck running
at top economy and in prolonging
its life is proper lubrication servicing.
Neglecting this essential aspect of
vehicle care can cost time and money
in the long run.
CAUTION
Do not mix different types of lubri-
cants.
Mixing lubricants (oil and
grease) of different brands or types
could damage vehicle components;
therefore, drain (or remove) old lu-
bricants from the unit before refilling
it.
Engine
Proper engine lubrication depends
on the outside temperatures where
you will be driving. Use the oil
recommended for the conditions you
are most likely to be operating in. You
will find a complete engine lubrication
service guide in the Engine Operation
Manual that came with your vehicle.
The engine operator manual contains
specific maintenance tasks that you or
a qualified service technician need to
perform to maintain the engine.
