When to Add Engine Oil
(Except Z06, ZR1, and Grand
Sport)
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. 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
(Z06, 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.

4. Remove the dipstick from theexternal 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.When to Add Engine Oil
(Z06, ZR1, and Grand Sport)
If the oil is below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) of the recommended oil
through the oil fill cap opening in the
oil tank and then recheck the level.

Changing Engine Oil and Filter
(Z06, ZR1, and Grand Sport)
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 changing the engine oil and
filter. Follow this procedure closely
when changing the engine oil
and filter.
Z06 Shown, ZR1 andGrand Sport Similar
A. Engine Oil Drain Plugs
B. Seals
1. Remove the two engine oil drain plugs from the bottom of the
engine oil pan. One drain plug
drains the external oil tank via
the oil transfer supply line.
The other drain plug drains
residual oil from the crankcase
sump. Allow the oil to drain. 2. Once the oil has been drained
from the engine, remove the
engine oil filter and allow the
oil to drain.
3. Re‐install both drain plugs and tighten them to 25 Y(18 lb ft).
4. Replace the oil filter and tighten it to 30 Y(22 lb ft).
See Maintenance Replacement
Parts on page 11‑14 for the
correct filter.
5. Oil is filled through the opening in the top of the external engine
oil tank. Remove the oil fill cap.
6. Add 9.9 L (10.5 quarts) of oil to the oil tank. See Capacities and
Specifications on page 12‑2.
7. Install the oil fill cap and insert the dipstick, if removed.
