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 Octane™ knock control“ will adapt the ignition timing, if necessary.
f Do not use fuel additives without Porsche approval.
Fuels containing ethanol
f
Do not use any fuels containing more than 10 percent ethanol by volume.
We recommend, however, to change to a different fuel or station if any of the following problems occur with your vehicle:
– Deterioration of driveability and performance.
– Substantially reduced fuel economy.
– Vapor lock and non-start problems, especially at high altitude or at high temperature.
– Engine malfunction or stalling.
