Gasoline additives
A ma jo r concern among many auto manufactur
ers is carbon deposit build- up ca used by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu
facturer to another, they have cer tain things in
common . All gaso line grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l 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 TIE R 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 o f using inadequate
fuels, carbon deposit bui ld-ups can rob your en
gine of peak performance.
