Using the right fuel helps keep the environ­
ment clean and prevents engine damage .
Fuel recomm endation
The fuel recommended for your vehicle is un ­
lead ed pr emium
grade gasoline . See also
¢ page 239, Data . Audi recommends using
TOP TIER Detergent Gasol ine with a minimum
octane rating of 91 AK I (95 RON). For more
information on TOP TI ER Detergent Gasoline,
p lease go to the officia l website (www.toptier­
gas.com).
The recommended gasoline octane rating for
your engine can a lso 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 veh icle 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 fue l wi ll slightly re ­
duce engine performance.
U se unl ead ed gasolin e onl y. 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.
F or more informat ion on refue ling your vehi­
cle, see
¢ page 175.
Octane rat ing
Octane rating ind icates a gasoline's ability to
resist engine damaging "knock" caused by
premature ign ition 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 us
ually be found on the fi ller
pump:
- 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 .
(D Note
-Do not use any fuel w ith octane rat ings
lower than 87 AKI or 91 RON otherwise
expensive engine damage w ill occur.
- Do
not use leaded gasoline! The use of
leaded gasoline w ill severely damage
your vehicle's catalytic converter and its
ability to control exhaust emissions .
Blended gasoline
Use of gaso line co ntainin g alc ohol or
MTBE (m ethyl tertia ry butyl eth er)
You may use unleaded gasoline blended with
alcohol or MTBE (commonly referred to as
oxygenates) if the blended mixture meets the
fo llowing criteria:
Blend of gaso line m ethanol (wood alc ohol or
methyl alcohol )
-Anti -knoc k index must be 87 A KI or h igher.
- Blend must contain no more than 3% meth-
anol.
- Blend must contain more than 2% co-sol-
vents .
Blend of g asoline and etha nol (gra in alcohol
or eth yl alcohol )
