-If you are unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified are not the respon­
sibility of Audi and are not covered under
the New Vehicle or the Emission Control
System Warranties .
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel blends, we
recommend that you switch to unblended
fuel.
Gasoline additives
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, carbon deposit build-ups can rob your
en­
gine of peak performance.
(D Note
Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle
Limited Warranty.
