Using the right fuel helps keep the environment clean and
prevents engine damage.
Fuel recommendation
Th e fuel recommended for your vehicle is unleaded premium grade
gasoline. See also=>
page 314, "Data". Audi recommends using TOP
TIER Detergent Gasoline with a minimum octane rating of 91 AKI (95
RON). For more information on TOP TIER Detergent Gasoline, please
go to the official website (www .toptiergas.coml.
The recommended gasoline octane rating for your engine can also be found on a label located either on the driver's side B-pillar (visible
when the door is open) or inside the fuel filler flap. This rating may
be specified as AKI or RON.
Your vehicle may also be operated using unleaded regular gasoline
with a minimum octane rating of 87 AKl/91 RON. However, using 87
AKl/91 RON octane fuel will slightly reduce engine performance.
Use unleaded gasoline only. Unleaded gasoline is available
throughout the USA, Canada, and in most European countries. We
recommend that you do not take your vehicle to areas or countries
where unleaded gasoline may not be available.
For more information on refueling your vehicle, see=>
page 245.
Octane rating
Octane rating indicates a gasoline's ability to resist engine
damaging "knock" caused by premature ignition and detonation.
The refore, buying the correct grade of gasoline is very important to
help prevent possible engine damage and a loss of engine perfor ­
mance. Gasoline most commonly used
in the United States and Canada has
the following octane ratings that can usually be found on the filler
pump:
• Pr emium Grade: 91 -96 AKI
• Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Kno ck Ind ex= (R+Ml/2 = (RON+MON)/2
RON= Research Octane Number
MON = Motor Octane Number .
0 Note
• Do not use any fuel with octane ratings lower than 87 AKI or 91
RON otherwise expensive engine damage will occur .
• Do
not use leaded gasoline. The use of leaded gasoline will
severely damage your vehicle's catalytic converter and its ability to
control exhaust emissions. •
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl
tertiary butyl ether)
You may use unleaded gasoline blended with alcohol or MTBE (commonly referred to as oxygenates) if the blended mixture meets
the following criteria:
Blend of gasoline methanol (wood alcohol or methyl alcohol)
• Anti-knock index must be 87 AKI or higher.
• Blend must contain no more than 3% methanol.
• Blend must contain more than 2% co-solvents.

If you plan to take your vehic le outside the continental limits of the
United States or Canada, there is the possibility that
• unleaded fue ls for vehicles with cata lyt ic converter may not be
available;
• f uel may have a considerably lower octane rat ing . Imprope r fuel
may cause engine damage;
• service may be inadequate due to lack of proper service facilities,
tools or testing equipment;
• replacement parts may not be readily avai lable . •
Navigation systems for vehicles built for the U.S.A . and Canada
wil l not necessarily work in Europe, and may not work in other coun ­
