•

• Anti -knock index must be 87 AKI or higher.
• Blend must not contain more than
10% ethanol.
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 seasona l change -over, we suggest
that you fil l 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 corrosion and damage to p lastic and rubber components in
the fue l system.
• Do not use fue ls that fail to meet the specified criteria in this
chapter .
• If you are unable to determine whether or not a particu lar fuel
blend meets the specifications, ask your service station or its fuel
suppl ier.
• Do not use fue l for which the contents cannot be identified.
• Fuel system damage and performance problems resu lting 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
Emission Control System Warranties.
• If you experience a loss of fuel economy or driveability and
performance problems 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 manufacturers is carbon
depos it 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 gaso line grades contain
substances that can cause deposits to collect on vita l engine parts,
such as fue l injectors and intake valves. Although most gasoline
brands include additives to keep engine and fue l systems clean,
they are not equally effective.
Audi recommends using TOP TIER Detergen t Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the offi­
cial website (www.toptiergas .coml.
A ft er an extended period of using inadequate fuels, built-up carbon
deposits can rob you r engine of peak performance.
(D Note
Damage or malfunction due to poor fuel qua lity is not covered by
the Audi New Vehicle Limited Warranty .•
