Gasolines containing alcohol
Gasoline containing alcohol is available at gas
stations in some areas. The gas pump may
not be labeled to identify that alcohol is present
i n the gasoline. If it is labeled, it may not identi-
fy what amount and type(s) of alcohol are used.
We recommend you do not use fuels where
the alcohol content cannot be identified.
Gasolines containing methanol
Do not u s e fuels containing methanol (methyl
alcohol, wood alcohol). The use of fuel con-
taining this type of alcohol can result in ve-
hicle driveability and performance problems
and may damage critical parts of your vehic-
le's fuel and emission control systems.
Gasolines containing ethanol
A mixture of unleaded gasoline and ethanol
(ethyl alcohol, grain alcohol) is sold in some
areas. This mixture is sometimes called "Gas-
ohol". You may use gasohol in your Porsche,
provided it contains no more than 10 % ethanol,
and the octane requirements for your vehicle
are met. However, we strongly recommend
switching back to gasoline without ethanol, if
you experience any of the following problems
with your vehicle:
60
• Deterioration of driveability and perfor-
mance.
• Substantially reduced fuel economy.
• Vapor lock and non-start problems, espe-
cially at high altitude or at high temperatures.
• Engine malfunction or stalling.
Continued use of gasohol under these con-
ditions may cause costly damage to the fuel
system and the emission control system of
your vehicle.
