Refuelling 

Fuel tank capacity is listed under “Capacities”.

Porsche does not recommend the use of fuel ad-

ditives.
f Please observe the chapter “CAPACITIES” on 

Page 183.

1. Important: Stop the engine and switch off the 

ignition. 

2. Slowly unscrew the tank cap.

Place the tank cap on the filler flap (arrow).

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 op-

erated automatic fuel-hose nozzle has 

switched off.

Fuel could spray or could run over in warm 

temperatures. 

5. Replace the tank cap immediately after 

refuelling and turn it until you hear it and feel it 

engage. 

Fuel Recommendations 

Your Porsche is equipped with catalytic convert-

ers and must use UNLEADED FUEL ONLY. 
Your engine is designed to provide optimum per-

formance and fuel economy using unleaded premi-

um fuel with an octane rating of 98 RON 

(93 CLC or AKI). Porsche therefore recom-

mends 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 tim-

ing, if necessary. 

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.
