2014/2015 Z51 and Z06 Corvettes – Additional Required Maintenance
The following message only applies to dry sump Corvettes that have not had their first oil change performed.
Some 2014/2015 Z51 and Z06 Corvettes may experience a condition that leads to oil leaking out from the air cleaner assembly. This
