Your
Porsche isequipped withcatalytic convert-
ers and must use
UNLEADED FUELONLY.

Your engine isdesigned toprovide optimum per-
formance andfuel economy usingunleaded premi-
um fuel with anoctane ratingof
98 RON
(93 CLC orAKI).
Porsche therefore recom-
mends theuse ofthese fuelsinyour vehicle.
Porsche alsorecognizes thatthese fuelsmaynot
always beavailable. Beassured thatyour vehicle
will operate properly onunleaded premiumfuels
with octane numbers ofatleast
95RON
(90 CLC orAKI),
sincetheengine's "Electronic

knock control" willadapt theignition tim-
ing, ifnecessary.

The useofUNLEADED FUELONLY is
critically important tothe lifeofthe catalytic
converters. Depositsfromleaded fuelswill
ruin theconverters andmake itineffective as
an emission controldevice.

Cars withcatalytic converters haveasmaller fuel
tank opening, andgas station pumps havesmaller
nozzles. Thiswillprevent accidental pumpingof
leaded fuelintocars withcatalytic converters.
