Model(s): 2006 Chevrolet Corvette Z06 with 7.0L V8 engine (VIN E - RPO LS7)

The 2006 Chevrolet Corvette Z06 is equipped with a dry sump oiling system. When adding oil to the LS7 dry sump oiling system, care must be taken to avoid overfilling the system.

Notice: Overfilling may cause over-pressurization to the system which may result in damage to the engine and emissions system components.

The capacity for the LS7 oil fill (with filter) is 7.6L (8 qts). When checking the oil level, follow the instructions found in the Owners Manual. However, if the amount of oil in the system is unknown due to repairs or other causes, the entire system should be drained and refilled with the correct amount of oil.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
