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.
Although gasoline grades d iffer from one manu-
facturer to another, they have cer t ain t hings 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 TIER Detergent Gas-
oline. For more information

gent Gasoline, please go to the official website

After an extended period of using inadequate
fuels, carbon deposit bui ld-ups can rob your en-
gine of peak performance.
