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
Octane™ knock control" will adapt the ignition timing, if necessary.
