Refueling Fuel tank capacity is listed under “Capacities”.
Porsche does not recommend the use of fuel ad-
ditives.
Fuel is highly flammable and harmful to 
health.
fPlease see the chapter “CAPACITIES” on 
Page 290.1.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 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 
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.
 Caution!
Risk of damage. Decorative film may fade if 
it comes into contact with fuel.
fWipe off any emerging fuel immediately.
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. 
It is important to observe the regular service inter-
vals, 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.
