When to Add Engine Oil (Z06 Only)
If the oil is below the cross-hatched area at the
tip of the dipstick, you need to add at least
one quart/liter of oil through the oil fill cap opening
in the oil tank. But you must use the right kind.
This section explains what kind of oil to use.
For engine oil crankcase capacity, see Capacities
and Specifications on page 426.
See Racing or Other Competitive Driving on
page 292 for additional information on engine oil.
Notice: Do not add too much oil. If 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.
Be sure to 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 you are through.
Changing Engine Oil and Filter
(Z06 Only)
Z06 models 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.

external engine oil
tank and fill cap.
