2013 AUDI A5 COUPE fuel additives

212 Fuel supply and filling your fuel tank
- 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 stat ions 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 flex ible fuel en­
gines. Using high ethano l fuel in vehicles
not equipped with flexib le fue l eng ines
can cause severe engine damage.
- Methanol fuels which do not mee t 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 identif ied.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the respons ibility 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 driveab ility and performance prob­
le ms 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: wit h flexible fue l e ngi ne
Vehicles with f lexible fuel engines may be op­
erated with bio-ethanol fuels such as E85 (85% ethano
l 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 wi ll increase when us­
ing bio-ethano l fue ls 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 . Th is fuel evaporates again
when the engine is warmed up.
II Please warm up engine.
If the driver message appears in the instru­
ment cluster disp lay, 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
eng ine or to the fuel system .
- Read and follow the information and t ips
about gasoline¢
page 211.
Gasoline additives
A major concern among many auto manufac­
turers is carbon depos it build-up caused by
the type of gaso line you use .
Although gasoline grades differ from one manufacturer to another, they have certain
th ings in common . All gasol ine grades conta in
substances that can cause deposits to collect
on vital engine parts, such as fue l injectors
and intake valves. A lthough most gasoline
brands include add itives to keep engine and
f uel systems clean, they are not equally effec­
tive .
Audi recommends using TOP TIER Detergent
Gasoline . For mo re information on TOP TIER .,.
