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.

Checking Engine Oil (Z06 Only)
A. Engine Oil Dipstick
B. Engine Oil Fill CapIt 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.
The dipstick is located on the dry sump engine
oil tank. SeeEngine Compartment Overview
on page 330for the location of the dry sump
engine oil tank.
Z06 models have 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 checking the engine oil level.
Follow this procedure closely when checking the
engine oil level.
334

The engine oil level must be checked when the
engine is warm. Cold oil level in the dry sump tank
may not indicate the actual amount of oil in the
system. With this system, engine oil is contained
in an external tank, separate from the engine.
Under normal operating conditions, the oil
pan under the engine does not store any oil.
If the vehicle has been parked for an extended
period without the engine being started, some
oil will seep back into the oil pan, reducing
the amount of oil held in the dry sump tank
and there could be no engine oil at all showing
on the dipstick. This is normal since the
dipstick is designed to read engine oil level
only after the engine has run long enough
to reach normal operating temperature.Do not add engine oil based on cold engine
dipstick readings. The engine oil level on the
dipstick will also be inaccurate if checked while
the engine is running.
1. To obtain an accurate engine oil level reading,
warm up the engine to at least 175°F (80°C).
Cold oil will not give a correct oil level reading.
2. Once the engine is warm, turn off the engine.
Checking the oil while the engine is running
will result in an incorrect oil level reading.
3. Wait at least ve minutes (but not more
than 20 minutes) to allow oil to drain and
settle in the engine.
4. Remove the dipstick from the external engine
oil tank and clean it with a lint-free paper
towel or a cloth. Re-insert the dipstick into
the external oil tank, pushing it all the way
in until it stops.
5. Remove the dipstick from the oil tank and
read the level on the cross-hatched area.
Oil levels that fall in the cross-hatched
area are normal.
335

When to Add Engine Oil (Except Z06)
If the oil is below the cross-hatched area at the
tip of the dipstick, you need to add at least
one quart/liter of oil. But you must use the right
kind. This section explains what kind of oil to use.
For engine oil crankcase capacity, seeCapacities
and Specications on page 426.
SeeRacing or Other Competitive Driving on
page 292for additional information on engine oil.
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.SeeEngine
Compartment Overview
on page 330for
the location of the
engine oil ll cap.
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.
