Always observe the following points:

-

Use only engine oils approved by Porsche.

This is a precondition for optimum and

problem-free operation of your vehicle.

-

The engine oil is changed regularly during

servicing.

It is important that the service intervals,

particularly the oil change intervals, are

observed in accordance with the specifications

in the Maintenance Schedule.

We recommend that you have the engine oil

changed at your authorized Porsche dealer.

-

Oils approved by Porsche can be mixed with

each other.
