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,
built-up carbon
deposits can
rob
your engine of peak performance.
