Fuel quality Your engine is designed to provide optimum performance and fuel economy using
unleaded premium fuel with an octane rating of 98 RON (93 CLC or AKI).
Porsche therefore recommends the use of these fuels in your vehicle.
Porsche also recognizes that these fuels may not always be available. Be assured that your vehicle
will operate properly on unleaded premium fuels with octane numbers of at least 95 RON (90 CLC or AKI),
since the engine’s “Electronic Oktane™ knock control” will adapt the ignition timing, if necessary.
