Audi Q3: Fuel

Types of gasoline

The correct gasoline grade is stated on the inside of the fuel filler door.

The vehicle is equipped with a catalytic converter and must only be driven with unleaded gasoline.

Audi recommends using TOP TIER Detergent Gasoline.

The individual gasoline grades are differentiated by octane ratings. This value is given with (R+M)/2 equating to AKI or in RON.

The headings below match the sticker in the fuel filler door (examples):

UNLEADED FUEL ONLY MIN. (R+M)/2 87 Regular / MIN. RON 91 Regular

Use regular gasoline with minimum 87 AKI / 91 RON.

Audi recommends using premium gasoline with minimum 91 AKI / 95 RON to achieve the rated horsepower and torque.

UNLEADED FUEL ONLY PREMIUM MIN.

(R+M)/2 91 / SUPER MIN. RON 95.

Using premium gasoline with minimum 91 AKI/ 95 RON is recommended.

If premium gasoline is not available, you can also use regular gasoline 87 AKI / 91 RON. However this does reduce the engine power slightly.

UNLEADED FUEL ONLY PREMIUM MIN.

(R+M)/2 93 / SUPER PLUS MIN. RON 98

Using premium plus gasoline with at least 93, AKI/ 98 RON is recommended.

If no premium plus gasoline is available, you can also use premium gasoline with 91 AKI / 95 RON.

However this does reduce the engine power slightly.

Note

• Filling the tank just one time with leaded fuel or other metallic additives will cause permanent deterioration to the catalytic converter function.
• When gasoline with an octane rating that is too low is used, high speeds or heavy engine load can lead to engine damage.

Tips

The vehicle may be filled with fuel that has a higher octane rating than what is required by the engine.

Gasoline mixture

Gasoline with alcohol (ethanol)

You can fuel your vehicle with unleaded gasoline that has an ethanol content of up to 15%, for example "E15".

Gasoline adapted to the season

Many gasoline fuels are adapted to the seasons.

When the season changes, refueling at high-traffic gas stations is recommended. It is more likely that the gasoline will be suitable for the season there.

Note

• Do not use gasoline that does not meet the specifications.
• Ethanol fuels with a high ethanol percentage, such as E30 - E100, must not be used.

  The fuel system will be damaged!

• Methanol fuels with a high methanol percentage, such as MS - M100, must not be used. The fuel system and the engine will be damaged!
• If you are unable to find out if a specific gasoline mixture meets the specifications, ask the gas station operator or their fuel supplier.
• Do not use any gasoline mixture whose composition cannot be identified.
• Audi does not assume any responsibility for damage to the fuel system or for performance problems caused by using gasoline mixtures different from those specified.

  This type of damage also does not fall under the New Vehicle Limited Warranty or under the emissions control system warranty.

• If you notice a higher fuel consumption or poor handling or performance problems due to such gasoline mixtures, Audi recommends fueling with unblended gasoline.

Gasoline additives

An important issue for many automobile manufacturers is combustion residue in the engine that results from the use of certain fuels.

Although types of gasoline differ depending on the manufacturer, there are similarities. Certain substances in the gasoline may cause deposits in the engine. Additives in the gasoline that should keep the engine and fuel system clean do not all function equally.

Audi recommends using TOP TIER Detergent Gasoline.

If you use incorrect fuels over a long period of time, the maximum engine performance may be impaired by combustion residue.

Note

• Damage or malfunctions caused by the use of incorrect types of gasoline are not covered by the New Vehicle Limited Warranty.
• Only gasoline additives that have been approved by Audi may be used.
