Using the right fuel helps keep the environment clean and
prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is unleaded premium grade
g asoline . See also :::>
page 296, "D ata ". Aud i recommends using TO P
TIER Detergent Gasoline with a minimum octane ra ting of 91 AKI (95
R O N). For more information on TOP TIE R Detergen t Gasoline, please
go to the official website (www. toptiergas .com) .
Th e recommended gasoline octane rating for your engine can also be
found on a labe l located on the ins ide of t he fue l fille r flap. This rating
may be specified as AKI or RON .
Your vehicle may also be ope rated us ing unleaded reg ular gasoline
with a minim um octane rating of 87 AKI/91 RON. However, us ing 87
AKI/91 RON octane fuel will slig htly reduce engine performance.
Use un leaded ga soline only. U nleaded gaso line is available
throughout the USA, Canada, and in most E uropean co untries. We
recommen d that you do not ta ke your veh icle to areas or co unt ries
where unleaded gasoline may not be available.

Octane rating
Octane r ati ng indi cat es a gaso line's abi lity to resis t engi ne damag ing
"knock" caused by premature ignition and detonat ion. Therefore,
buying the correc t g rade o f gasol ine is very impo rtan t to help preve nt
possible engine damage and a loss of engine performance .
Gaso line most common ly used in the United States and Canada has
the following octa ne rat ings tha t ca n usually be fou nd on the filler
pump :
Safety first
• Premium Grade: 91 - 96 AKI
• Regular Grade: 87 - 90 AKI
Explanation of t he abb reviations :
AKI= Anti Knock Index= (R +M)/2 = (RON+ MON)/2
RO N= Research Octane Number
M ON= M otor Octane Num ber.
0 Note
• Do not use any fue l with octane rat ings lower than 87 AKI o r 91
RON otherwise expens ive engine damage will occ ur.
• Do
not use leade d gasoline! The use o f leaded gaso line will
severely damage your veh icle 's cata lytic converter and its abi lity to
cont rol exhaust emissions .•
