Changing Engine Oil And Filter - Chevrolet 2009 Corvette Owner's Manual

When to Add Engine Oil (ZO6 and ZR1)
If the oil is below the cross-hatched area at the tip of the
dipstick, add at least one quart/liter of the recommended
oil through the oil fill cap opening in the oil tank. This
section explains what kind of oil to use. For engine oil
crankcase capacity, see Capacities and Specifications
on page 5-110.
See Racing or Other Competitive Driving on page 4-15
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.
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

(ZO6 and ZR1)
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.
See Engine Compartment
Overview on page 5-14 for
the location of the external
engine oil tank and fill cap.
