is
stated
on
the

The
vehicle
is
equipped
with
a
catalytic

and
must
only
be
driven
with
unleaded

Audi
recommends
using

are
differentiated
by
octane
ratings.
This
value
is
given
with
(R

equating
to
AKI
or
in
RON.

Note
—
Filling
the
tank
just
one
time
with
leaded
fuel
or
other
metallic
additives
will
cause
permanent
deterioration
to
the
catalytic
converter
function.
—
When
gasoline
with
an
octane
rating
that
is
too
low
is
used,
high
speeds
or
heavy
engine
load
can
lead
to
engine
damage.
@
Tips
The
vehicle
may
be
filled
with
fuel
that
has
a
higher
octane
rating
than
what
is
required
by
the
engine.
Gasoline
mixture
Gasoline
with
alcohol
or

(Methyl-Tert-
Butyl-Ether)
You
can use
unleaded
gasoline
mixed
with
alco-
hol
or

(generally
labeled
as
oxygenated
compounds)
as
long
as
the
fuel
meets
the
follow-
ing
conditions:
Gasoline
with
methanol
content
(methyl
alco-
hol
or
methanol)
—
Anti-Knock
Index
is
at
least
87
AKI
—No
more
than
3%
methanol
—
More
than

Gasoline
adapted
to
the
season
Many
gasoline
fuels
are
adapted
to
the
seasons.
When
the
season
changes,
refueling
at
high-traf-
fic
gas
stations
is
recommended.
It
is
more
likely
that
the
gasoline
will
be
suitable
for
the
season
there.
