-Methanol f uels which do not mee t these re­
quirements may ca use corrosion and dam­
age to plastic and rubber components in the

fied criteria in this chapter.

the New Veh icle or the Emiss ion Control
System Wa rrant ies.
- If you experience a loss of fue l economy or
driveability and performance problems due

Gasoline additives
A ma jo r concern among many auto manufactur ­
e rs is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu ­
facturer to ano ther, they have certain things in
common . All gasoline grades contain substances
that can cause deposits to collect on v ita l eng ine
parts, such as fuel 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 informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www .toptiergas .com) .
Check ing and Filling
After an extended period of using inadeq uate
fuels, carbon deposit bui ld-ups can rob your en­
gine of peak performance.
(D Note
Damage or ma lf u nction due to poor fuel qual ­
ity is not covered by the A udi New Vehicle
