Chevrolet 2011 Corvette Owner's Manual page 307

See Racing or Other Competitive
Driving on page 9 7 for additional
information on engine oil.
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 10 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 (ZO6,
ZR1, and Grand Sport)
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
yellow loop. The dipstick is located
on the dry sump engine oil tank.
See Engine Compartment Overview
on page 10 10 for the location of the
dry sump engine oil tank.
Vehicle Care
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
tank and there could be no engine
oil at all showing on the dipstick.
