Checking and Filling

Fuel

Note

– Filling the tank just one time with leaded

fuel or other metallic additives will cause

permanent deterioration to the catalytic

converter function.

Types of gasoline

The correct gasoline grade is stated on the inside

of the fuel filler door.

– When gasoline with an octane rating that is

too low is used, high speeds or heavy engine

load can lead to engine damage.

The vehicle is equipped with a catalytic converter

and must only be driven with unleaded gasoline.

Tips

Audi recommends using TOP TIER Detergent Gas-

oline. For additional information on TOP TIER De-

The vehicle may be filled with fuel that has a

higher octane rating than what is required by

the engine.

The individual gasoline grades are differentiated

by octane ratings. This value is given with

(R+M)/2 equating to AKI or in RON.

Gasoline mixture

Gasoline with alcohol (ethanol)

The headings below match the sticker in the fuel

filler door (examples):

You can fuel your vehicle with unleaded gasoline

that has an ethanol content of up to 15%, for ex-

ample “E15”.

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

Regular / MIN. RON 91 Regular

Gasoline adapted to the season

Use regular gasoline with minimum 87 AKI /

91 RON ð

Many gasoline fuels are adapted to the seasons.

When the season changes, refueling at high-traf-

fic gas stations is recommended. It is more likely

that the gasoline will be suitable for the season

there.

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

Note

Using premium gasoline with minimum 91 AKI /

95 RON is recommended.

– Do not use gasoline that does not meet the

specifications.

– Ethanol fuels with a high ethanol percent-

age, such as E30 – E100, must not be used.

The fuel system will be damaged!

– Methanol fuels with a high methanol per-

centage, such as M5 – M100, must not be

used. The fuel system and the engine will be

damaged!

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 you are unable to find out if a specific gas-

oline mixture meets the specifications, ask

the gas station operator or their fuel suppli-

er.

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.

– 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 perform-

ance 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 recom-

mends fueling with unblended gasoline.

There is a malfunction in the fuel tank system.

Drive to an authorized Audi dealer or authorized

Audi Service Facility immediately to have the

malfunction corrected.

There is a malfunction. The manual release must

be used to unlock the fuel filler door ðpage 249.

An important issue for many automobile manu-

facturers is combustion residue in the engine

that results from the use of certain fuels.

The fuel tank is almost empty. You must antici-

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.
