230 Maintenance and Car Care
Fuel Recommendations
Your Porsche is equipped with catalytic converters and must use UNLEADED FUEL WITHOUT METALLIC ADDITIVES ONLY .
Your engine is designed to provide optimum performance and fuel economy using unleaded premium fuel with an octane rating of 98 RON/ 88 MON (93 CLC or AKI) . Porsche therefore recommends 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/ 85MON (90 CLC or AKI) , since the engine’s “Electronic Octane™ knock control” will adapt the ignition timing, if necessary.
If fuels of less than 95 RON/85 MON (90 CLC or AKI) are used however, this could reduce performance and increase fuel consumption.fAvoid driving at full throttle.
It is important to observe the regular service intervals, and particularly the oil change intervals, specified in the “Maintenance” booklet.
The use of UNLEADED FUEL WITHOUT METALLIC ADDITIVES ONLY is critically important to the life of the catalytic converters. Deposits from leaded fuels or metallic additives will ruin the converters and make them ineffective as an emission control device. Metallic additives can cause serious engine damage.
Cars with catalytic converters have a smaller fuel tank opening, and gas station pumps that dispense unleaded fuel have smaller nozzles. This will prevent accidental pumping of leaded fuel into cars with catalytic converters.
Unleaded fuels may not be available outside the continental U.S. and Canada. Therefore, we recommend you do not take your car to areas or countries where unleaded fuel may not be available.
Information
In some countries the available fuel quality may not meet the requirements of your Porsche vehicle and can result in coking inside or around the injector bores or other serious damage to the engine, fuel system or exhaust system.
In this case, the fuel may be mixed only with the additive sold and recommended by Porsche after consulting your authorized Porsche dealer.
Porsche part number 000 043 206 89.fObserve the instructions and mixture ratios stated on the container.
It is important that the service intervals, particularly the oil change intervals, are observed in accordance with the specifications in the “Maintenance” booklet.
Risk of destruction of the engine, fuel system or exhaust system if non-approved additives are used.fUse only additives approved by Porsche. The use of other additives can result in destruction of the engine, fuel system or exhaust system of your vehicle.
Octane ratings
Octane rating indicates a fuel’s ability to resist detonation. Therefore, buying the correct octane gas is important to prevent engine “damage”.
The RON octane rating is based on the research method. The CLC (U.S. Cost of Living Council octane rating) or AKI ( antiknock index) octane rating usually displayed on U.S. fuel pumps is calculated as research octane number plus motor octane number, divided by 2, that is written as:
The CLC or AKI octane rating is usually lower than the RON rating:
For example: 95 RON equals 90 CLC or AKI.
Fuels containing ethanol
Do not use any fuels containing more than 15 percent ethanol by volume.
We recommend, however, to change to a different fuel or station if any of the following problems occur with your vehicle: – Deterioration of drivability and performance. – Substantially reduced fuel economy. – Vapor lock and non-start problems, especially at high altitude or at high temperature. – Engine malfunction or stalling.

250 Minor Repairs
Wheel alignment, wheel balancing
As a precaution, have wheels with summer tires balanced in the spring, and those with mud and snow tires before winter. Unbalanced wheels may affect car handling and tire life.Only the specified weights may be used for wheel balancing.
Self-adhesive weights must not come into contact with cleaning agents, since they could drop off.Uneven tread wear indicates wheel imbalance. In this event, the vehicle should be checked at an authorized Porsche dealer.
If, during a trip, uneven running or vibrations occur that could be caused by damage to tires or the car, the speed must be reduced immediately, but without braking sharply. If you continue your trip without having the cause of the fault remedied, you might lose control of your vehicle.fStop the vehicle and check the tires.fIf no cause for the fault can be found, drive carefully to the nearest authorized Porsche dealer.
The summer tires of your Sports Car have been specially developed and adapted for high performance. At low outside temperatures (<15°C (60°F)), the tire characteristics change. This can result in noises occurring when parking or maneuvering at low outside temperatures.
Wheels with Tire Pressure Monitoring System (TPMS) sensors
Before changing wheels, make sure that the wheels are compatible with your vehicle’s TPMS.fCheck this with your authorized Porsche dealer.
Removing and storing tires
fAfter changing, adjust tire pressure and torque wheel bolts diagonally. Please see the chapter “CHANGING WHEELS” on page 254.fStore tires in a cool and dry place. Rotate periodically to avoid flat spots.fDo not store summer tires or park vehicles fitted with summer tires at ambient temperatures below 5 °F (-15 °C).fAvoid contact with fuel, oil and grease.
Tires must always remain on the same side of the vehicle.When wheels are removed, the direction of rotation and position of each wheel should be marked.
Example
FR (front right), FL, RR and RL.
Wheels must always be fitted in accordance with their marking.
The perception that tire durability and performance are not affected by storage and age is unfounded. Chemical additives, which make the rubber elastic, lose their effectiveness over the course of time and the rubber becomes brittle and cracks.
Therefore, the tires should be inspected from time to time.
Information
Under no circumstances should tires older than 6 years be used on your Porsche.
The age of the tire can be obtained from the “DOT” code number. If, for example, the last four numbers read 1213, then the tire was produced in the 12th week of 2013.
Snow tires
The installation of Porsche approved snow tires is recommended.
Use Porsche approved snow tires for grip on snow and ice. Summer performance tires are not suitable for usage in cold, snowy, or icy conditions.Check with your local Motor Vehicle Bureau for possible restrictions.
