CHEVROLET KODIAK 2008 Owners Manual

Look for this information on the oil container, and use
only those oils that are identified as meeting GM
Standard GM6094M and have the starburst symbol on
the front of the oil container.
Notice:Use only engine oil identied as meeting
GM Standard GM6094M and showing the American
Petroleum Institute Certied For Gasoline Engines
starburst symbol. Failure to use the recommended
oil can result in engine damage not covered by
your warranty.If you are in an area of extreme cold, where the
temperature falls below−20°F (−29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both provide easier
cold starting and better protection for the engine at
extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended oils
with the API service symbol are all you need for
good performance and engine protection.

Engine Oil (DURAMAX®Diesel
Engine)
Checking Engine Oil
It is a good idea to check the engine oil level every time
you get fuel.
The engine oil dipstick is
located in the engine
compartment on the driver
side of the vehicle.
In order to get an accurate reading, the engine should
be at normal operating temperature, so that the oil
is warm, and the vehicle must be on level ground.
1. If the engine is at normal operating temperature and
the oil is warm, turn off the engine and allow at
least five minutes for the oil to drain back into the
oil pan. If you do not do this, the oil dipstick
might not show the actual level.If the engine has not been run long enough to bring
it up to normal operating temperature and the oil
is cool, turn off the engine and allow 30 minutes for
the oil to drain back into the oil pan. If you do not do
this, the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or a cloth, then push it back in all the way.
3. Remove the dipstick again, keeping the tip down,
and check the oil level.
5-28

When to Add Engine Oil
If the oil is below the cross-hatched area at the tip of
the dipstick, add at least two quarts/liters of the
recommended oil. This section explains what kind of oil
to use. For engine oil crankcase capacity, see
Capacities and Specifications on page 5-109.
Notice:Do not add too much oil. If the engine has
so much oil that the oil level gets above the
cross-hatched area that shows the proper operating
range, the engine could be damaged.Add oil at the engine oil fill
cap in the engine
compartment. Install and
fully tighten the fill cap
when you are through.
Be sure to add enough oil to put the level somewhere in
the proper operating range. Push the dipstick all the
way back in when you are through.
5-29

What Kind of Engine Oil to Use
Look for three things:
•CJ-4
Oils designated as API CJ-4 are required for your
vehicle. The CJ-4 designation can appear either
alone or in combination with other American
Petroleum Institute (API) designations, such as API
CJ-4/SL. These letters show API levels of quality.
Notice:Use only engine oils that have the
designation CJ-4 for the diesel engine. Failure to
use the recommended oil can result in engine
damage not covered by your warranty.
5-30

•SAE 15W-40
As shown in the viscosity chart, SAE 15W-40 is best
for your vehicle. When it is very cold, below 0°F
(−18°C), you should use SAE 5W-40 to improve cold
starting.
These numbers on the oil container show its
viscosity, or thickness. Do not use other viscosity
oils such as SAE 10W-30, SAE 10W-40, or
SAE 20W-50.
This doughnut-shaped
logo (symbol) is used on
most oil containers to help
you select the correct oil. It
means that the oil has been
certified by the American
Petroleum Institute.
Look for this on the oil container, and use only those
oils that display this logo.Engine Oil Additives
Do not add anything to the oil. The recommended oils
with the API service symbol are all you need for good

When to Change Engine Oil (Vehicles
Without the Engine Oil Life System)
Change the engine oil and filter every 15,000 miles
(24 000 km), or every 12 months, or every 750 hours of
engine operation, whichever occurs first. See
Scheduled Maintenance on page 6-5.

Engine Oil (Isuzu Diesel Engine)

located in the engine
compartment on the driver
side of the vehicle.
In order to get an accurate reading, the engine should
be at normal operating temperature, so that the oil
is warm, and the vehicle must be on level ground.
1. If the engine is at normal operating temperature and

2. Pull out the dipstick and clean it with a paper towel
or a cloth, then push it back in all the way.
3. Remove the dipstick again, keeping the tip down,
and check the oil level.
When to Add Engine Oil
Notice:Do not add too much oil. Keep the oil level
between the ADD and FULL marks on the dipstick.
Under normal engine operation, the engine oil
level can increase above the FULL mark as a result
of DPF regeneration. A small increase in the oil
level is normal. If the engine has so much oil that
the oil level reaches the wider portion (A) on the
dipstick, the engine oil must be changed as soon as
possible or the engine could be damaged.

If the oil is below the ADD
mark on the dipstick, add
at least one quart/liter
of the recommended oil.

oil crankcase capacity, seeCapacities and
Specifications on page 5-109.Add oil at the engine oil fill

is used primarily for long trip, highway service, change
the engine oil and filter every 18,000 miles (28 800 km),
or every 12 months, or every 750 hours of engine
operation, whichever occurs first. SeeScheduled
Maintenance on page 6-5.

Engine Oil Life System (Gasoline
Engine)
When to Change Engine Oil
Your vehicle has a computer system that lets you know
when to change the engine oil and filter. This is based
on engine revolutions and engine temperature, and not
on mileage. Based on driving conditions, the mileage at
which an oil change will be indicated can vary
considerably. For the oil life system to work properly, you
must reset the system every time the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A change engine oil light will come on. See
Change Engine Oil Light on page 3-38. Change the oil as
soon as possible within the next 600 miles (1 000 km).
It is possible that, if you are driving under the best
conditions, the oil life system might not indicate that an oil
change is necessary for over a year. However, the engine
oil and filter must be changed at least once a year and at
this time the system must be reset. Your dealer/retailer
has trained service people who will perform this work
using genuine parts and reset the system. It is also
important to check the oil regularly and keep it at the
proper level.If the system is ever reset accidentally, you must
change the oil at 3,000 miles (5 000 km) since your last
oil change. Remember to reset the oil life system
whenever the oil is changed.How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to change
the engine oil and filter based on vehicle use. Whenever
the oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation occurs
where you change the oil prior to a change engine oil light
being turned on, reset the system.
To reset the change engine oil light:
1. Turn the ignition key to ON/RUN with the
engine off.
2. Fully press and release the accelerator pedal slowly
three times within 10 seconds.
If the change engine oil light flashes for
five seconds, the system is resetting.
3. Turn the key to OFF.
If the change engine oil light comes back on when you
start your vehicle, the engine oil life system has not
reset. Repeat the procedure.
