oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication
and cool ing of internal
engine
components, all internal combustion
engines consume
a
certain amount of oil. Oil consumption
varies from engine to engine
and may
change
significantly
over
the life of
the engine. Typically,
engines with a specified break -in period (see
~
page 192) consume
more oil during
the
break-in period
than they
consume after oi
l
consumption
has stabi
lized
.
Unde
r
normal conditions, the rate of oil consumption
depends on
the quality and viscosity of the oil, the RPM (revolutions per minute)
at which the engine is operated, the ambient temperature and road
conditions
.
Further factors
are
the amount of oil dilution from water
condensation
or fuel residue and
th
e oxidation level of the o il. As
any engine is subject
to
wear as mileage builds up, the oil consump
-
tio
n
may increase over time unt il rep lacement of worn components
may become necessary.
With
all these
variables coming
into
play, no standard rate of oil
consu
m
ption can be estab lished or specified. There is no alternative
to regular and
frequent
checking of the oil
level,
see
Note
.
If
the yellow engi ne oil level warning symbol in the instrume nt
cluster
lights
up, you should check
the
oil level as soon as

•
The oil pressure
wa
rning displ
ay
ce,.
is
not an indicat or of the oil
level.
Do not rely on it. Instead
,
check the oil level in your engine at
regular interv
als,
preferably each time you
refuel,
and always before
going on a long trip.

If you have the impression your engine consumes excessive
amoun
t
s of oi l, we recommend tha
t
you consult your Audi dealer to
have the cause of your concern properly diagnosed
.
Keep in mind
that the accurate measureme nt of
o
il consumption
requires great
care
and may
take
some
time.
Your Audi dealer has instructions
about how to measure oil consumption
accurately.
