Blend of gasoline and MTBE
• Anti-knock index must be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform especially well for
winter or summer driving. During seasonal change-over, we suggest
that you fill up at busy gas stations where the seasonal adjustment is
more likely to be made in time.
0 Note
• Methanol fuels which do not meet these requirements may cause
corros ion and damage to plastic and rubber components in the fue l
system .
• Do not use fuels that fail to meet the specified criteria in this
chapter.
• If you are unab le to determine whether or not a particu lar fuel
blend meets the specifications, ask your service station or its fuel
s u pplier.
• Do not use fue l 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 responsi ­
bility of Audi and are not covered under the New Vehicle or the Emis­
sion Control System Warranties.
• If you experience a loss of fuel economy or driveability and perfor­
mance problems due to the use of one of these fuel blends, we
recommend that you switch to unblended f uel. •
Gasoline additives
A major concern among many auto manufacturers is carbon depos it
build -up caused by the type of gasoline you use.
Safety first
Although gasoline grades differ from one manufacturer to another,
t hey have certain things in common. All gasoline grades contain
substances that can cause depos its to collect on v ital engi ne 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 officia l
webs ite (www.toptiergas.com).
After an extended per iod of using inadequate fuels, built-up carbon
deposits can rob your engine of peak performance .
0 Note
Damage or malfunction due to poor fuel quality is not covered by the
Audi New Vehicle Limited Warranty. •

Fuel supply and filling your fuel tank
In order to fill the tank properly while protecting the environment,
please follow this refueling procedure carefully.
& WARNING
Under normal operating conditions, never carry additional fuel
containers in your car. Gas canisters and other containers used to
transport fuel can be dangerous. Such containers, full or empty,
may leak and could cause a fire in a collision. If you must transport
fuel to use for your lawn mower, snow blower, etc., be very careful
and always observe local and state laws regarding the use, trans­
portation and storage of such fuel containers. Make certain the
container meets industry standards (ANSI/ASTM F852 -86).
0 Note
Never drive your vehicle until the fuel tank is completely empty . The
irregular supply of fuel can cause misfiring. Gasoline could enter the
exhaust system and damage the catalytic converter. •
