Fuel supply and filling your fuel tank
Gasoline
Fuel supply
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 341, "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.
F or more in formation on re fueling yo ur vehicle, see:::>
page 272.
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
RO N otherwise expens ive engine damage will occ ur.
• Do
not use leaded gasoline. The use of lea ded gasoline w ill
severely damage your veh icle 's cata lytic converter and its abi lity to
cont rol exhaust emissions .•
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl
tertiary butyl ether)
Yo u may use unleaded gasoline blended w ith alcoho l or MTBE
( c ommon ly referred to as oxygenates) if the blended mix ture meets
the following criteria:
Blend of ga soline methanol (wood alcohol or methyl alcohol)
• Anti -k nock index m ust be 87 AKI or h igher .
• Bl end must con tain no mo re t han 3% methanol.
• Blend must contain more than 2% co-solvents.
Blend of ga soline and ethanol (grain alcohol or ethyl alcohol)
• Anti-knock index must be 87 AKI o r higher.
• Bl end must no t contain more th an 10% ethanol.
Vehicle care Technical data
