Checking Engine Oil (Except Z06)
If the CHECK OIL LEVEL message on the Driver
Information Center (DIC) comes on, check the
engine oil level right away. For more information,
seeDriver Information Center (DIC) on page 207.
You should check the engine oil level regularly;
this is an added reminder.
It is a good idea to check the engine oil level
every time you get fuel. In order to get an accurate
reading, the oil must be warm and the vehicle
must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 330
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil a few
minutes 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
lint-free paper towel or a cloth, then push
it back in all the way. Remove it again,
keeping the tip down.

Your vehicle’s engine is lled at the factory
with a Mobil 1®synthetic oil, which meets all
requirements for your vehicle.
Substitute Engine Oil: When adding oil to
maintain engine oil level, oil meeting GM
Standard GM4718M may not be available.
You can add substitute oil designated SAE 5W-30
with the starburst symbol at all temperatures.
Substitute oil not meeting GM Standard GM4718M
should not be used for an oil change.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
Standard GM4718M are all you need for good
performance and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer that lets you know
when to change your engine oil and lter.
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.
Z06 models are equipped with a racetrack-ready
dry sump engine lubrication system. This
high-performance system operates differently
than a standard engine lubrication system
and requires a special procedure when changing
the engine oil and lter. SeeEngine Oil
on page 333.

What to Use
Use a mixture of one-half clean, drinkable water
and one-half DEX-COOL®coolant which will
not damage aluminum parts. If you use this coolant
mixture, you do not need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water,
or some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system
is set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.Notice:If you use an improper coolant
mixture, your engine could overheat and be
badly damaged. The repair cost would not be
covered by your warranty. Too much water
in the mixture can freeze and crack the engine,
radiator, heater core, and other parts.
If you have to add coolant more than four times
a year, have your dealer check your cooling
system.
Notice:If you use extra inhibitors and/or
additives in your vehicle’s cooling system,
you could damage your vehicle. Use only
the proper mixture of the engine coolant
listed in this manual for the cooling system.
SeeRecommended Fluids and Lubricants
on page 443for more information.

the coolant surge tank, but be sure the cooling
system, including the coolant surge tank pressure
cap, is cool before you do it. SeeEngine
Coolant on page 347for more information.
If no coolant is visible in the surge tank, add
coolant as follows:
{CAUTION:
Steam and scalding liquids from a hot
cooling system can blow out and burn
you badly. They are under pressure, and if
you turn the coolant surge tank pressure
cap — even a little — they can come out
at high speed. Never turn the cap when
the cooling system, including the coolant
surge tank pressure cap, is hot. Wait
for the cooling system and coolant
surge tank pressure cap to cool if you
ever have to turn the pressure cap.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system is
set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.
Notice:In cold weather, water can freeze and
crack the engine, radiator, heater core and
other parts. Use the recommended coolant
and the proper coolant mixture.
