See “Selecting the Right Engine Oil”
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 10‑8 for the location of the
external engine oil tank and fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back into the oil tank when through.
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.

Grand 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.
