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 AKI or RON.
Your vehicle 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 to areas or countries
where unleaded gasol ine may not be availab le.

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 AKI
Explanation of the abb reviations:
AKI=
Anti Knock Index = (R+M)/2 = (RON+MON)/
2
RON = Research Octane Number
MON= Moto r Octane Number .
(D 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 .
