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 8 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.

(Z06, ZR1, manual

Coupe, and 427 Convertible)
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.
