Gasolines containing ethanol
A mixture of unleaded gasoline and ethanol (ethyl alcohol, grain alcohol) is sold in some areas. This mixture is sometimes called "Gasohol". 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 to switch back to gasoline without ethanol, if you experience any of the following problems with your vehicle:
• Deterioration of driveability and performance.
• Substantially reduced fuel economy.
• Vapor lock and non-start problems, especially 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.
