Lubricant Specifications
WARNING! Handle lubricants carefully. Vehicle
lubricants (oil and grease) can be poisonous and
cause death, injury or sickness. They can also
damage 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 service more frequently if you are oper-
ating 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 lubri-
cant supplier. And 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 differ-
ent brands or types could damage vehicle
components; therefore, drain (or remove) old
lubricants from the unit before refilling it.
Engine
NOTE: The engine in this vehicle may comply with
EPA emission standards. Consult the engine manu-
facturer’s manual for changed lubrication and main-
tenance requirements.
Proper engine lubrication depends on the outside tempera-
tures where you will be driving. Use the oil recommended for
the conditions you are most likely to be facing. You will find a
complete engine lubrication service guide in the Engine
Operation Manual that came with your vehicle. There, the
engine manufacturer explains more fully all the maintenance
operations that you and a qualified service mechanic need to
perform on your engine.
WARNING! Exhaust fumes from the engine con-
tain carbon 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 or sleeper. Entry of carbon monoxide into the
cab is also possible from other vehicles nearby.
Failure to properly maintain your vehicle could
cause carbon monoxide to enter the cab/sleeper
and cause death or serious illness
