A new mileage interval has been established for the first engine oil change on 2014-2015 Corvette Stingray models with the Z51 Performance Package and Z06 models.
These vehicles are equipped with an engine featuring a dry sump oil system. The first oil change should take place at 500 miles (800 km) on these vehicles.

If the vehicle is driven continuously at a high engine speed with the first factory oil fill, silicone sealants in the engine’s gaskets may degrade the anti-foaming properties of the oil.
This may lead to oil leaking out from the air cleaner assembly due to the oil foaming condition.
The oil foam does not affect the engine’s durability, but changing the oil at 500 miles will help prevent oil foaming in the future because the silicone sealants are removed with the original oil.

A. Dry sump engine oil tank fill cap

B. Engine oil dipstick

C. Engine air cleaner/filter

Once the break-in oil change is performed and the Oil Life Monitor is reset, owners should follow the Oil Life Monitoring system for all future oil change needs.

TIP:
Only use Mobil 1 when performing an oil change on any Corvette under the Chevrolet Complete Care program.

An additional oil change has been added to the required maintenance schedule.

Up to five oil changes are now covered as part of the Chevrolet Complete Care program, which covers 2 years/24,000 miles (38,600 km) of select required maintenance.

A second printing of the 2015 Owner Manual is being updated with this change.
