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.
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.
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.
Vehicle Care
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
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.
