fuel additives AUDI S4 SEDAN 2013 Owners Manual

-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 sea­ sonal adjustment is more likely to be made in
time.
CD Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only
be used in vehicles with flexible fuel en­
gines. Using high ethanol fuel in vehicles
not equipped with flexible fuel engines
can cause severe engine damage.
- 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 fail to meet the
specified criteria in this chapter.
- If you are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service 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 responsibility 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
lems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Ethanol fuel (Bio-ethanol)
Applies to vehicles: with flexible fuel engine
Vehicles with flexible fuel engines may be op­
erated with bio-ethanol fuels such as E85
Fuel supply and filling your fuel tank 211
(85% ethanol and 15% gasoline) or with un­
leaded gasoline (91 AKI/ROZ 95). The vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption will increase when us­
ing bio-ethanol fuels due to the lower amount
of energy contained per unit volume in etha­
nol.
Warming up the Flexible fuel engine in low temperatures
Due to the chemical composition of bio-etha­
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in very
low temperatures . This fuel evaporates again
when the engine is warmed up .
II Please warm up engine.
If the driver message appears in the instru­
ment cluster display, drive with a warm en­
gine to reduce the oil level.
CD Note
- Never fill with methanol or with a higher
percentage of bio-ethanol than 85%
(E85). A higher percentage of bio-etha­
nol in the fuel can cause damage to the
engine or to the fuel system.
- Read and follow the information and tips
about gasoline¢
page 210.
Gasoline additives
A major concern among many auto manufac­
turers 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 gasoline grades contain
substances that can cause deposits to collect
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 are not equally effec­
tive.
Audi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER ..,.
