Engine oil specifications (8-cyl.-engine )
The engine in your Audi needs the right kind

The engine in your Audi is a soph istica ted

engine oi l that meets specifications regarding
qua lity and viscosity so that it can run
smoothly and reliably. Choos ing the right oi l
and changing oil within the time and mileage intervals printed in your veh icle's Warranty

Ma intenance book let matters a lot more to
day than it d id yea rs ago. A udi has developed
a special quality standa rd for engine oil that
will he lp assure tha t your veh icle's eng ine will

M odern eng ine lub rication has taken a quan

oils availa ble today provide be tter eng ine lu

for use throughout the life of your A udi.
Whether yo u use syn thetic or petroleum

specifications of Audi oi l standard VW 502 00
are synt het ic eng ine oi ls . Th is does not mean,
however, that every synthetic engine oil will

be sure that you use an approved oil.

Changing the engine oil
The engine oil and o il filter must be changed
according to the mi leage (ki lometers) and
time interva ls specified in your vehicle's War
ranty
& Maintenance booklet . Do not exceed
these intervals -harmful depos its from old
engine o il can reduce engine performance and
can lead to expensive engine repairs .
C hanging the o il at the recommended inter
va ls is so very important because the lubricat
ing properties of oi l decrease gradually during
normal vehicle use. If you are not sure when
you have your o il changed, ask your author
ized A udi Service Advisor .
Under some circumstances the engine o il
should even be changed more frequently .
C hange o il mo re often if you dr ive mostly
short d istances , operate the vehicle in dusty
a reas or mostly under s top-and -go traffic con
d itions , or when yo u use your veh icle whe re
temperatures stay below free zing point fo r

a reason to change the oi l more often than
recommended.

Engine oil consumption
T he engine in your vehicle depends on an ade
quate amoun t of oil to lubricate and cool all
of its moving par ts.
In order to provide effective l ubrication and
cooling of internal engine components, a ll in
ternal comb ustion eng ines consume a certa in
amount of o il. O il consumption var ies from
engine to eng ine and may c hange significa ntly
over the life of the eng ine . T ypically, eng ines
with a specifie d break-in per iod (see
c::> p oge 153) consume more oil during the
b reak-in per io d t han they co nsume after oil
consumption has sta bilized.
Unde r no rma l conditions, the rate of oil con
sum ption depends on the qu ality and vi scosity
of the oi l, the R PM ( revo lutions per m inute) at
which t he engine is ope rated, the ambient
temperature and road cond itio ns. Furthe r fac
tors are the amount of o il d ilution from water
condensation or fuel residue and the ox ida
ti on level of the oi l. As any engine is subject to
wear as mileage bu ilds up , the oil consump
tion may increase over t ime until replacement
of worn componen ts may become necessary.
W ith all these variables com ing into play, no
standa rd rate of o il consumption can be es
tablished or specif ied . T he re is no alternative
to regular and frequent checking of the oil lev
e l, see
Note .
If the ye llow eng ine o il level warning symbol

Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro tects the engine from freezing in the winter.
The cooling system is sea led and generally re
q ui res lit tle at ten tion.
The cooling system has been filled at the fac
tory with a pe rma nent coolant which does not
need to be changed. The coolant consists of a
mix ture o f wa ter and the m anu fa ctu rer 's g ly
col -based coolant addit ive Gl3 antifreeze
with anticorrosion additives (50% for USA mod els; 60% for Canadian models) . This mix
ture both assures the necessary frost protec
tion and protects metal components i n the
engine's cooling system from corrosion and
scaling .
It also raises the bo iling po int of the
coolant.
Do not reduce the concentration of the coo l
ant in the summer by adding plain water.
The
proportion of coolant addit ive must b e at
lea st 50% but not more than 60 %
to main
tain antifree ze protection and cooling efficie n
cy.
If t he cool ant frost pro tect io n is too low,
the coo lant cou ld freeze and damage the veh i
cle heating and engine cooling system.
Checkin g and fillin g 181
For year -round driving, antifreeze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- -40 °F ( -40 °C) Canada.
