Introduction

WARNING!
Handle lubricants carefully. Vehicle lu-
bricants (oil and grease) can be poi-
sonous and cause death, personal in-
jury or sickness. They can also dam-
age the paint on the vehicle.
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
5
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
5-34
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 lubricants.
Mixing lubricants (oil and grease) of
different brands or types could dam-
age vehicle components; therefore,
drain (or remove) old lubricants 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.
