Gasoline
additives
A major concern among many auto manufacturers is carbon
deposit build-up caused by the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another,
they have certain things in common. All gasoline grades contain
substances that can cause deposits to collect on vital engine parts,
such as fuel injectors and intake valves. Although most gasoline
brands include additives to keep engine and fuel systems clean,
they are not equally effective.
Audi recommends using TOP TIER Detergent Gasoline. For more
information
on TOP TIER Detergent Gasoline, please go to the offi-
cial website (www.toptiergas.com).
After an extended period of using inadequate fuels, carbon deposit
build -ups can rob your engine of peak performance.
