To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10‑19.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.

Checking Engine Oil (Except
Z06, ZR1, manual transmission
Grand Sport Coupe, and 427
Convertible)
If the CHECK OIL LEVEL message
displays on the Driver Information
Center (DIC), check the engine oil
level right away. For more
information, seeEngine Oil
Messages on page 5‑39. Check the
engine oil level regularly; this is an
added reminder.
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
See Engine Compartment Overview
on page 10‑8 for the location of the
engine oil dipstick. Obtaining an accurate oil level
reading is essential:
1. If the engine has been running
recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
{WARNING
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
2. Pull the dipstick and clean it with a paper towel or cloth, then push
it back in all the way. Remove it
again, keeping the tip down, and
check the level.
When to Add Engine Oil
(Except Z06, ZR1, manual
transmission Grand Sport
Coupe, and 427 Convertible)
If the oil is below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) of the recommended oil
and then recheck the level. See
“Selecting the Right Engine Oil” in
this section for an explanation of
what kind of oil to use. For engine
oil crankcase capacity, see
Capacities and Specifications on
page 12‑2.
See Racing or Other Competitive
Driving on page 9‑6 for additional
information on engine oil.

Black plate (15,1)Chevrolet Corvette Owner Manual - 2013 - crc2 - 11/8/12
Vehicle Care 10-15
Notice:Do not add too much oil.
Oil levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If you find that you
have an oil level above the
operating range, i.e., 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. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil.
See Engine Compartment Overview
on page 10‑8 for the location of the
engine oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range . Push the dipstick all the way
back in when through.Checking Engine Oil (Z06, ZR1,

A. Engine Oil Dipstick
B. Engine Oil Fill Cap
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground.
The engine oil dipstick handle is a
loop. The dipstick is located on the
dry sump engine oil tank. See
Engine Compartment Overview
on page 10‑8 for the location of the
dry sump engine oil tank.
These vehicles 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.
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
