The correct grade of petrol is listed inside the fuel tank flap.
The vehicle is equipped with a catalytic converter and must only be run on unleaded petrol. The petrol must comply with the EN 228 or DIN 51626-1 standard and must be sulphur-free. You can fuel your vehicle with fuels containing a maximum of 10% ethanol (E10). The petrol grades have different octane ratings (RON).
The following headings relate to the sticker on the inside of your vehicle s tank flap:
Unleaded fuel only RON/ROZ 98 Super Plus or min. RON/ROZ 95 Super, Premium
The use of Super Plus petrol (98 RON) is recommended. If that type of fuel is not available, premium petrol (RON 95) can be used with a slight loss of power.
If premium petrol is not available, the engine can be run on regular petrol with 91 RON as an emergency measure. In this case only use moderate engine speeds and a light throttle. Fill up with premium or Super Plus petrol as soon as possible.
CAUTION
- Do NOT fuel your vehicle with high-ethanol fuel blends (e.g. E50 or E85). This will damage the fuel system.
- Just one tank of leaded fuel or fuel with metallic additives will permanently impair the efficiency of the catalytic converter.
- You should use only petrol additives which have been approved by Audi. Additives with so-called octane boosters or antiknock additives can contain metallic additives that cause significant damage to the engine and the catalytic converter. Do not use such additives.
- Metal-based fuels, which can be identified from the marking on the fuel dispenser, must not be used. LRP fuel (lead replacement petrol) also contains high concentrations of metallic additive. Risk of engine damage!
- High engine speed and full throttle can damage the engine when using petrol with an octane rating lower than the correct grade for the engine.
Note
- You can use higher octane fuel than your engine requires.
- In countries where sulphur-free fuel is not available, you may use low-sulphur fuel instead.
