2012 AUDI A6 fuel additives

216 Fuel supply and filling your fuel tank
-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driv ing.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time.
(CT) Note
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system .
- Do not use fuels that fai l to meet the
specified criteria in this chapter.
- If yo u are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel sup plier.
- Do not use fuel for which the contents cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the respons ibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac ­
turers is carbon deposit build- up caused by
the type of gasoline you use.
A lthough gasoline grades differ from one
manufacturer to another, they have certain
things in common. All gasoline g rades contain
substances that can cause deposits to co llect
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 a re not equally effec­
tive .
A udi 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 uels, carbon deposit build-ups can rob yo ur
engine of peak performance.
