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.

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 10 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:

  1. Deterioration of driveability and performance.
  2. Substantially reduced fuel economy.
  3. Vapor lock and non-start problems, especially at high altitude or at high temperature.
  4. Engine malfunction or stalling.

Fuel recommendations diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) sulfur content 15 ppm or less.

The ULSD (Ultra Low Sulfur Diesel) meets the ASTM-D-975 (grade 2).

Risk of engine damage and/or damage to the fuel system and a costly repair not covered by the New Vehicle Limited Warranties if diesel fuel with a higher concentration of sulfur than ULSD (Ultra Low Sulfur Diesel) is used.

  • Only use ULSD (Ultra Low Sulfur Diesel) ASTM-D-975 (grade 2).
  • Always exercise great care to avoid misfueling.

Risk of engine damage and/or damage to the fuel system if diesel fuel with a higher concentration of biodiesel than 5 % is used like B11, B20 or B100.

  • Only use diesel fuel with a blend of 5 % biodiesel (B5) or below.

Risk of engine damage and/or damage to the fuel system if home heating oil or gasoline is used.

The diesel vehicle is not designed to use home heating oil or gasoline and must never be filled or driven with home heating oil or gasoline.

  • If you have filled the vehicle with home heating oil or gasoline, do not switch on the ignition under any circumstances and do not start the engine.
  • Contact your authorized Porsche dealer.
