@ Tips
I t may take longer to start the engine
when the outside temperature is very cold.
If possible, use winterized fuel if tempera­
tures are below freezing.
Gasoline additives
A major concern among many auto manufac­
turers 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 depos its to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
b rands include additives to keep eng ine and
fuel systems clean, they are not equally effec­
tive.
Aud i recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas .com).
After an extended period of using inadequate
f u els, b uilt-up carbon deposits can rob your
engine of peak performance.
CJ) Note
-Damage or malfunct ion due to poor fuel
quality is not covered by the Audi New
Vehicle Limited Wa rranty.
- Do not add aftermarket fuel addit ive
products to your fuel tank .
