Gasoline additives
Applies to: vehicles with gasoline engine
A major concern among many auto manufactur
ers is carbon deposit build-up caused by the type
of gasoline you use .
Although gasoline grades differ from one manu
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engine parts, such as fuel injectors and intake valves.
Al
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas
oline. For more information on TOP TIER Deter
gent Gasoline, please go to the official website (www.toptiergas .com) .

After an extended period of using inadequate
fuels, built-up carbon deposits can rob your
en
gine of peak performance.

- Damage or malfunction due to poor fuel
quality is not covered by the Audi New Vehi
cle Limited Warranty.
- Do not add aftermarket fuel additive prod
ucts to your fuel tank.
Diesel fuel
Applies to: vehicles with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) No. 2.
The ULSD No. 2 meets the ASTM 0975.
Diesel fuel with concentrations of biodiesel high
er than 5
% such as 811,820 or 8100 are strictly
prohibited.
Service station fuel pumps are labeled with the
correct fuel information for easy recognition by
the user. If the diesel fuel pump is not labeled
ask the station operator what fuel is being dis
pensed before filling up your vehicle.
ULSD No. 2 may not be available outside the USA
and Canada. Be sure to check before traveling to
other countries.
ULSD No. 2 can become thicker in very cold tem
peratures, and this can impair the engine's start
ing and running . Depending on the season , gas
stations provide ULSD No. 2 that flows better in
cold temperatures so that you can continue oper
ating your vehicle as usual.
(D Note
- Your vehicle's diesel engine was designed
soley for use with ULSD No. 2. Therefore,
never use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system
and the engine. Such damage will not be
covered by your New Vehicle Limited War
ranty.
- If you put any amount of incorrect fuel in
the fuel tank, do not start the engine under
.,..
