Chevrolet 2009 Corvette Owner's Manual page 293

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 in
when you are through.

It is a good idea to check the engine oil level every time
you get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
