Gasoline additives
Applies to vehicles : wit h gasoli ne engine
A majo r concern among many auto manufac-
ture rs is carbon deposit build-up caused by
the type of gasoline you use.
Although gasoline grades differ from one
manufacturer 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. Although most gasoline

brands include additives to keep engine and
fuel systems clean, they are not equally effec-
tive .
Audi recommends using TOP TIER Detergent
Gasoline . For more information on TOP TIER
Detergent Gasoline, please go to the official
webs ite (www.toptiergas.com).
After an extended per iod of using inadeq uate
fuels, carbon deposit build-ups can rob your
engine of peak performance.

Diesel
fuel
Applies to veh icles: with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel)
No. 2. The ULSD No. 2 meets the ASTM D97S.
Diesel fuel with concentrations of biodiesel
highe r than S % such as Bll, B2O or BlOO are
strictly prohib ited .
Service stat ion fuel pumps are labeled with
the cor rect fuel informat ion for easy recogn i-
tion by the user. If the diesel fue l pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
ULSD No. 2 may not be available outside the
USA and Canada. Be sure to check before trav-
eling to other countries .
ULSD No. 2 can become thicker in very cold
temperatu res, and this can impair the en-
gine'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 operating your vehicle as usua l.
CD
Note
- Your vehicle's diesel engine was de-
signed soley for use with ULSD No. 2.
Therefore, never use gasoline, heating
oil, other fuels or flow improvers. These
conta in substances that will severely
damage the fuel system and the engine .
