Lubricants
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.
WARNING!
Handle lubricants carefully. Vehicle lubri-
cants (oil and grease) can be poisonous and
cause death, personal injury or sickness.
They can also damage the paint on the ve-
hicle.
CAUTION
Do not mix different types of lubricants. Mix-
ing lubricants (oil and grease) of different
brands or types could damage vehicle com-
ponents; 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.
WARNING!
Exhaust fumes from the engine contain car-
bon monoxide, a colorless and odorless
gas. Do not breathe the engine exhaust gas.
A poorly maintained, damaged or corroded
exhaust system can allow carbon monoxide
to enter the cab. Entry of carbon monoxide
into the cab is also possible from other vehi-
cles nearby. Failure to properly maintain
your vehicle could cause carbon monoxide
to enter the cab, resulting in death or per-
sonal injury.
WARNING!
Never idle your vehicle for prolonged peri-
ods of time if you sense that exhaust fumes
are entering the cab. Investigate the cause
of the fumes and correct it as soon as possi-
ble. If the vehicle must be driven under
these conditions, drive only with the win-
dows open. Failure to repair the source of
the exhaust fumes may result in death, per-
sonal injury, equipment or property damage.
NOTE
Keep the engine exhaust system and the
vehicles cab ventilation system properly
maintained. It is recommended that the ve-
hicles exhaust system and cab be inspected
(1) By a competent technician every 15,000
miles (24,140 km) (2) Whenever a change is
noticed in the sound of the exhaust system
(3) Whenever the exhaust system, under-
body, or cab is damaged.
