Fuel and Refueling
Fuel
Gasoline
Applies to: vehicles with gasoline engine
Using the right fuel helps keep the environment
clean and prevents engine damage .
Fuel recomm endati on
The fuel recommended for your vehicle is
unlead-
ed premium
grade gasoline. Audi recommends
using TOP TIER Detergent Gasoline with a mini-
mum octane rat ing of 91 AKI (95 RON). For more
information on TOP TIER Detergent 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 located
on the inside of the fuel filler flap . This rating
may be spec ified as AK I or RON.
Your veh icle may also be operated using unlead-
ed regular gasoline with a minimum octane rat -
ing of
87 AKl/9 1 RON .
However, using
87 AKl/91
RON octane fuel will slightly reduce engine per-
formance.
Use unleaded gasoline only.
Unleaded gasoline
is available throughout t he USA, Canada, and in
most European count ries . We recommend that
you do not ta ke your vehicle t o areas or countries
where unleaded gasol ine may not be availab le.
For more information on refueling your vehicle,
see ~ page 211 .
Octane rating
Octane rating indicates a gasoline's ability to re-
sist engine damaging "knock" caused by prema-
ture ignit ion and detonation . Therefore , buying
the correct grade of gasoline is very important to
help prevent poss ible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat-
ings that can usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
Fuel and Re fueling
- Regular Grade: 87 - 90 AK I
Explanation of the abb reviations:
AK I=
Anti
Knock I ndex = (R+M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON= Moto r Oct ane Number .

Note
- Do not use any fue l wit h octane ratings low-
er than 87 AKI or 91 RON ot herwise expen-
sive engine damage will occur .
- Do
not
use leaded gasoli ne. The use of lead-
ed gasoline will severe ly damage your vehi-
cle's catalyt ic converter and its ability to
cont rol exhaust emissions .
Blended gasoline
Applies to: vehicles with gasoline engine
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether )
You may use unleaded gasoline blended with al-
cohol or MTB E (commonly referred to as oxygen-
ates) if the blended mixture meets t he follow ing
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% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
- Anti-knock index must be 87 AKI or higher .
- Blend must not conta in more than 15% etha-
nol.
- Vehicles with flex ible fue l* engine: blend must
not contain more tha n 85% ethanol.
Blend of gasoline and MTBE

- Blend must contain not more than 15% MTBE.
