2011 AUDI A5 COUPE technical specifications

Fuel supply and filling your fuel tank
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 fo r
winter or summer driving. During seasonal change-over, we suggest
that you fill up at busy gas stat ions where the seasonal adjustment is
more likely to be made in time.
0 Note
• Methano l fuels which do not meet these requirements may cause
corrosion 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 spec ifications, ask your serv ice station or its fuel
supplier.
• 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 responsi­
bility of Aud i and are not covered under the New Vehicle or the Em is­
sion Control System Warranties.
• If you experience a loss of fuel economy or driveab ility and perfor­
mance 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 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 gaso line g rades contain
substances that can cause deposits to collect on v ital engine parts,
such as fuel injectors and intake valves. A lthough most gasoline
brands include additives to keep eng ine 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 period 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 tank
Fuel filler neck
The fuel filler neck is located on the right rear side panel behind the
fuel filler flap .
If the power locking system should fail, you can still open the flap
manually- for detailed instructions see~
page 273.
You can find the fue l tank capacity of your vehicle in Technical Data
~page 339.
The label on the inside of the fuel filler flap tells you the correct fuel
for your ve hicle. For more information about fuel specifications, see
~page 269.
Your vehicle fuel tank has an on-board refue lling vapor recovery
system. This feature helps to prevent fuel vapors from escaping from
the tank and polluting the environment wh ile you refuel your veh icle . ..,_

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the right kind of oil.
The engine in your Audi is a sophisticated power plant that was built
to exacting specifications. This engine needs the right kind of engine
oil that meets specifications regarding quality and viscosity so that it
can run smoothly and reliably. Choosing the right oil and changing oil
within the time and mileage intervals printed in your vehicle's
Warranty
& Maintenance booklet matters a lot more today than it did
years ago. Audi has developed a special quality standard for engine oil
that will help assure that your vehicle's engine will get the lubrication
it needs for proper operation.
Modern engine lubrication has taken a quantum leap in the last few
years. Many synthetic oils available today provide better engine lubri­
cation that can outlast traditional petroleum-based oils, making
them a smart choice for use throughout the life of your Audi.
Whether you use synthetic or petroleum-based engine oil, the oil that
you use must conform to Audi's oil quality standard VW 502 00 to help keep your vehicle's engine running smoothly and help prevent
the formation of harmful deposits, sometimes called "sludge", that
over time can lead to expensive repairs.
Safety first
At the time of printing, engine oils available in the U.S. and Canada
that meet the exacting specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the formation of harmful deposits use only oil with
the following specifications printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specification singly or in combina­
tion with other designations and oil quality standards.
Viscosity
Engine oils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasonal conditions where you drive. You can use oil with a viscosity grade of
SAE SW40 across all temperature ranges for normal driving condi­
tions.
However, if engine oil viscosity grade SAE SW40 is not available, you
can also use viscosity grade SAE SW-30 or SAE OW-40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
Because engine oil that meets the Audi oil standard may not be avail­
able everywhere when you need it, we strongly recommend that you
always carry with you an extra quart (liter) of oil that expressly
conforms to the VW 502 00 specification, in case you have to top off
the oil while on the road.
Only if the level of the oil is at or below the minimum mark - and no
oil that expressly conforms to Audi oil standard VW 502 00 specifica­
tions is available -may you top off with a high quality engine oil, pref­
erably synthetic-based, that meets ACEA A3, ACEA AS or ACEA BS or
API SL specifications, but even then, only in viscosity grades SAE SW-
40, SAE SW-30, or SAE OW-40. However, during the entire time
between oil change intervals, never top off with more than a total of
0.5 qt/liter engine oil that does not conform to Audi oil specification
vw 502 00. ..
