Fuel supply and filling your fuel tank
Gasoline
Fuel supply
Using the right fuel helps keep the environment clean and
prevents engine damage.
Fuel r ecomm end ati on
The fuel recommended for your vehic le is unl eade d prem ium grade
gaso line . See also ~
page 296, "Data". Audi recommends using TOP
T IER Detergent Gasoline with a minimum octane rating of 91 AKI (95
RON). For more information on TOP TIER Detergent Gaso line, please
go to the official website (www.toptiergas .com).
The recommended gasoline octane rating for your engine can also be found on a label located on the inside of the fuel fille r flap. This
rating may be specified as AK I or RON .
Your vehic le may also be operated us ing unleaded regular gasoline
with a minimum octane rating of 87 AKl/91 RON . However, using 87
AKl/9 1 RON octane fuel will slightly reduce engine performance.
Use unle ad ed ga so line only . Unleaded gaso line is avai lable
throughout the USA, Canada, and in most European countries. We
recommend that you do not take your vehicle to areas or countr ies
where un leaded gasoline may not be available .
For more information on refueling your vehicle, see~
page 219 .
Octane ra tin g
Octane rating indicates a gaso line's ability to resist engine
damaging "knock" caused by premature ignition and detonation.
Therefore, buying the correct grade of gaso line is very important to
help prevent possible engine damage and a loss of engine perfor ­
mance. Gasoline most common
ly used in the United States and Canada has
the following octane ratings that can usua lly be found on the filler
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 = M otor Octane Number .
0 Note
• Do not use any fue l 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
severe ly damage your vehicle's catalytic converter and its abi lity to
control exhaust emissions. •
Blended gasoline
Use of g aso line containing alco hol or M TB E ( meth yl
t er tiary butyl e ther )
You may use unleaded gasoline blended with alcohol or MTBE
(commonly referred to as oxygenates) if the blended mixture meets
the follow ing criteria:
Bl end of g asoline m eth anol (wood al coho l or methyl alc oh ol)
• 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.
