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.
f Please 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.
f Wipe 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.
