Gasoline
Fuel supply
Using the right fuel helps keep the environ­
ment clean and prevents engine damage.
Fuel recommendation
The fuel recommended for your vehicle is un­
leaded premium
grade gasoline. Audi recom­
mends using TOP TIER Detergent Gasoline
with a minimum octane rating of 91 AKI (95
RON) . For more information on TOP TIER De­
tergent Gasoline, please go to the official
website (www.toptiergas.com).
The recommended gasoline octane rating for
your engine can also be found on a label locat­
ed on the inside of the fuel filler flap. This rat­
ing may be specified as AKI or RON.
Your vehicle may also be operated using un­ leaded regular gasoline with a minimum oc­
tane rating of 87 AKI/91 RON. However, using
87 AKI/91 RON octane fuel will slightly re­
duce engine performance.
Use unleaded gasoline only. Unleaded gaso­
line is available throughout the USA, Canada,
and in most European countries. We recom­
mend that you do not take your vehicle to
areas or countries where unleaded gasoline
may not be available.
For more information on refueling your vehi­
cle, see~
page 176.
Octane rating
Octane rating indicates a gasoline's ability to
resist engine damaging "knock" caused by
premature ignition and detonation. Therefore,
buying the correct grade of gasoline is very
important to help prevent possible engine
damage and a loss of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane ratings that can usually be found on the filler
pump:
Fuel supply and filling your fuel tank 175
- Premium Grade: 91 -96 AKI
- Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Knock Index= (R+M)/2 = (RON
+MON)/2
RON= Research Octane Number
MON= Motor Octane Number.
@ 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% meth-
anol.
- Blend must contain more than 2% co-sol-
vents.
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
- Anti-knock index must be 87 AKI or higher.
- Blend must not contain more than 15%
ethanol.
Blend of gasoline and MTBE
- Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline

Operating your vehicle
outside the U.S.A. or

If you p lan to take your vehicle outside the
continental limits of the United States or Can­
ada, there is the possibility that:
- unleaded fuels for vehicles with cata lytic
converter may not be available;
- fuel may have a considerably lower octane
rating . Improper 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 availa­
