Gasoline additives
Applies to: vehicles with gasoline engine
A majo r concern among many auto manufactur ­
ers is carbon deposit build-up caused 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 . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves . A l­
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 informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www .toptiergas .com) .
Check ing and F illing
A fter an extended period of using inadequate
fuels, carbon deposit bui ld-ups can rob your en ­
gine of peak performance.

Damage or ma lf u nction due to poor fue l qual ­
ity is not covered by the A udi New Vehicle
