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.
The engine oil dipstick handle is a yellow loop.
The dipstick is located on the dry sump engine
oil tank. See Engine Compartment Overview
on page 330 for the location of the dry sump
engine oil tank.
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 checking the engine oil level.
Follow this procedure closely when checking the
engine oil level.
