Refueling

Fuel tank capacity is listed under "Capacities". Porsche does not recommend the use of fuel additives.

Fuel is highly flammable and harmful to health.

  • Please see the chapter "CAPACITIES" on page 271.
  1. Important: Stop the engine and switch off the ignition.
  2. Slowly unscrew the tank cap.
    Hang the tank cap's plastic strap on the hook on the inside wall of the filler flap.
  3. Insert fuel-hose nozzle fully into the filler neck with the handle of the fuel-hose nozzle facing down.
  4. Do not add further fuel once the correctly operated automatic fuel-hose nozzle has switched off.
    Fuel could spray or could run over in warm temperatures.
  5. Replace the tank cap immediately after refueling and turn it until you hear it and feel it engage.

If you lose the tank cap, you must replace it only with an original part to reduce the possibility of a fire in the event of a collision.


Risk of damage. Decorative film may fade if it comes into contact with fuel.

  • Wipe off any emerging fuel immediately.

Fuel Recommendations
Your Porsche is equipped with catalytic converters and must use UNLEADED FUEL ONLY.

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 Oktaneā„¢ knock control" will adapt the ignition timing, if necessary.

It is important to observe the regular service intervals, and particularly the oil change intervals, specified in the "Maintenance" booklet.

The use of UNLEADED FUEL ONLY is critically important to the life of the catalytic converters. Deposits from leaded fuels will ruin the converters and make it ineffective as an emission control device.

Cars with catalytic converters have a smaller fuel tank opening, and gas station pumps have smaller nozzles. This will prevent accidental pumping of leaded fuel into cars with catalytic converters.
