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 gaso line grades contain substances
that can cause deposits to collect on vita l eng ine
parts, such as fuel injectors and intake valves. Al-
though most gasoline brands include additives to
keep eng ine and fuel systems clean, they are not
equa lly 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 depos its can rob your en-
gine of peak performance .
