Gasoline additives
A major 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 certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on v ita l engine
parts, such as fue l injectors and intake valves . Al
though most gasoline brands include addit ives 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
fue ls, built-up carbon deposits can rob your en
g ine of peak performance.
