2016 AUDI RS7 SPORTBACK engine

Driving and the environment
The engine and catalytic converter have to reach
their optimal
operating temperature to reduce
fuel consumption and noxious emissions effec­
tively.
Just after starting, a cold engine in a mid-size car
only achieves a fuel economy of 6-8 miles per
gallon (30-40 l/100 km). After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km). After about
2.5 miles (4 km), the engine is
at its proper operating temperature and fuel
economy has reached a normal level. So you can
see that you should avoid short trips whenever
possible.
The
outside temperature is also critical in this re­
gard. Your car consumes more fuel in the winter
than in the summer .

Using the right fuel helps keep the environment
clean and prevents engine damage.
Fuel recommendation
The fuel recommended for your vehicle is unlead­
ed premium
grade gasoline . Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
p lea se go to the offic ial website
(www.toptiergas .com).
The recommended gasoline octane rating for
your engine can also be found on a label located
on the ins ide of the fuel filler flap . This rating
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regular gasoline with a minimum octane rat­
ing of 87 AKl/91 RON . However, using 87 AKI/91
RON octane fuel wil l slightly reduce engine per­
formance.
Use unleaded gasoline only. Unleaded gasoline
is availab le throughout the USA, Canada, and in
most European countries . We recommend that
you do not take your vehicle to areas or countries
where un leaded gaso line may not be available.
For more information on refueling your vehicle,
see
¢page 199.
Octane rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore, buying
the correct grade of gasoline is very important to
he lp prevent possible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat­
i n gs that can usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
198
- Regular Grade: 87 - 90 AKI
Explanation of the abbreviations:
AKI = Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON= Motor Octane Number.
{[) Note
-Do not use any fuel with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage wi ll occur .
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions .
Blended gasoline
Applies to: vehicles with gasoline engine
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al­
cohol or MTBE (commonly referred to as oxygen ­
ates) if the blended mixture meets the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti -knock index must be 87 AKI or h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
- Anti-knock index must be 87 AKI or h igher .
- Blend must not contain more than 15% etha-
nol.
Blend of gasoline and MTBE
-Anti-knock index must be 87 AK I or higher .
- Blend must contain not mo re than 1S% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you .,..

fill up at busy gas st ations where the season al
adjustm ent is mor e likely to be made in time .
(D Note
-Me thanol f uels which do not mee t these re­
quirements may ca use corros ion and dam­
age to plastic and rubber components in the
fuel system .
- Do not use fuels that fai l to meet the speci­
fied criter ia in this chapter.
- If you are unable to determine whether or not a particular fuel blend meets the speci­
ficat ions, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identif ied.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Wa rrant ies.
- If you experience a loss of fue l economy or
driveability and performance prob lems due
to the use of one of these fuel b lends , we
recommend that you switch to unblended
fuel.
Gasoline additives
A ma jo r concern among many au to manufactur ­
e rs is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline gr ades d iffer from one manu ­
facturer to ano ther, they have cer tain things in
common . All gasoline grades contain substances
that can cause deposits to coll ect on v ita l eng ine
parts, such as f uel injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Aud i recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter -

Putting the fuel cap back on
.. After filling your tank, twist the fuel filler cap
clockwise as far as it will go.
.. Close the fuel filler flap.
To avoid fuel spilling or evaporating from the fuel
tank always close fuel filler cap properly and
completely. An improperly closed fuel filler cap
may also cause the MIL lamp ¢
page 28 to come
on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns. -
- Fuel is highly flammable and can cause se­
vere burns and other injuries .
- Failure to shut the engine off while refuel­
ing and/or to insert the pump nozzle fully
into the fuel filler neck could cause fuel to
spray out of filler neck or to overflow. Fuel
spray and overflowing fuel can cause a fire.
- Never use a cellular telephone while refuel­
ing. The electromagnetic radiation can
cause sparks that can ignite fuel vapors and
cause a fire.
- Never get back into your vehicle while refu­
eling.
If in exceptional circumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch metal to discharge static electric­
ity before touching the filler nozzle again.
Static electricity can cause sparks that can
ignite fuel vapors released during refueling.
- Never smoke or have an open flame any­
where in or near your vehicle when refueling
or filling a portable fuel container .
- For your safety, we strongly recommend
that you do not travel with a portable fuel
container in your vehicle. The container, full
or empty may leak and could cause a fire,
especially in a crash .
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container while it
is anywhere in or on the vehicle (for exam­
ple, in the luggage compartment, or on
the trunk). Static electricity can build up
Ii>-

while filling and can ignite fuel vapors causing a fire.
- Always place a portable fuel conta iner on
the ground before filling.
- Always keep the filler nozz le completely
inside the portab le container before and
during filling.
- If fill ing a portable container made of
metal, the filler nozzle must always be in
contact with the container . This will help
prevent static electricity from discharging
and cause a fire.
- Never spi ll fuel inside the vehicle or lug­
gage compartment. Fuel vapors are h ighly
flammable.
- Always observe local and state/provincia l
laws regarding the use, storage and trans ­
portation of fuel containers.
- Make certa in the fuel conta iner meets in­
dustry standards (ANSI/ ASTM F852-86).
CD Note
If any fuel has spilled onto the car, it should
be removed immediately to prevent damage
to the paint .
@ For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first t ime,
the tank is full. Do not try to add more fuel
because fuel may spill out. In addition, the
expansion space in the fuel tank will be filled -
causing the fuel to overflow when it becomes
warm and pollu te the environment.
@ Tips
- Running your engine while refuelling may
cause vapors to escape or even cause fuel to
spill out of the tank. This would then shut
off the fuel nozzle before the tank is full.
- Do not refuel your vehicle with the ignition
switched on. The fuel ga uge may otherwise
not indicate the correct fue l level after refu­
elling.
- The fuel filler flap of your vehicle is not
l ocked when you lock the vehicle from the
i nside.
