2008 AUDI S6 recommended oil

-~_C_ h_e _c _ k_ i_n ...:::g::;...._ a_n_ d_ f_ i_ll _in -'g:::;.._ ___________________________________________ _
current list of oils (manufacturers, brand names etc.) that conform
t o Audi oi l standard VW 502 00 .
Changin g the engine oil
The engine oil and oil filter must be changed according to the
mi leage (ki lometers) and time intervals specified in your vehicle's
Maintenance
& Warranty booklet. Do not exceed these interva ls -
harmful deposits from old engine oil can reduce engine perfor­
mance and can lead to expensive engine repairs.
Changing the oi l at the recommended intervals is so very important
because the lubricating prope rties of oi l decrease gradual ly during
normal vehicle use . If you are not sure when you have your oil
changed, ask your author ized Audi Serv ice Advisor.
Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you dr ive mostly short
distances, operate the vehicle in dusty areas or mostly under stop ­
and -go t raffic conditions, or when you use your vehicle where
temperatures stay be low freezing point for long per iods.
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time . This is normal and is not
a reason to change the oil more often than recommended.
Damag e or malfunctions due to lack o f mainten anc e
It is essentia l that you change your oi l at the recommended interva ls
using on ly engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle Warranty does not cover damage or ma lfunctions due to failure to follow recommended
main tenance and use requirements as set forth in the Aud i Owner's
Manual and Maintenance
& Warranty booklet. Your dealer wi ll have
t o deny warranty cove rage unless you present to the dealer p ro o f in
the form of Service or Repair Orders that all schedu led maintenance
was pe rformed in a timely manner. •
Engine oil consumption
The engine in your vehicle depends on an adeq uate
amount of oil t o lubric ate and c ool all of its m oving parts.
In order to provide effective lubrication and coo ling of interna l
engine components, al l interna l combustio n eng ines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significant ly over the life of the engine . Typ ically,
engines with a specified break-in period (see=> page 267) consume
more oil du ring the break-in period than they consume after oil
consumption has stabi lized .
Unde r normal conditions, the rate of oil consumption depends on
the quality and v iscosity of the oil, the RPM (revolutions per minute)
at which the engine is operated, the ambient temperature and road
cond itions. Fur ther factors are the amount of oil di lu tion from wate r
condensation or fue l residue and the oxidation leve l of the oi l. As
any engine is subject to wear as mileage bu ilds up, t he oil consump ­
tion may increase over time until replacement of worn components
may become necessa ry .
With all these variables coming into play, no standard rate o f oi l
consumption can be established or specified . There is no alternative
t o regula r and frequent checking of the oil level, see
Note .
If the yel low engine oil level warning symbo l in the instrument
clus ter lights up, yo u should check the oil level as soon as
possible with the oil dipstick=> page 301. Top off the oil at your
ea rliest convenience => page 302 .
& WARNING
Before you check anything in the engine compartment , always
read and heed all WARNING S
=> & in "Working in the engine
compartment " on
page 297.

because the lubricating properties of oil diminish gradually during
normal vehicle use .
Under some circumstances the engine oil should be changed more
frequently . Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or under predomi ­
nantly stop -and -go traffic conditions, or have your vehicle where
temperatures remain below freez ing for extended periods.
Detergent additives in the oi l will make fresh oil look dark after the
engine has been running for a short time. This is normal and is not
a reason to change the oi l more often than recommended .
Because of the problem of proper disposal, along with the specia l
tools and necessary expertise required, we strongly recommend
that you have your oi l changed by an authori zed
Audi dea ler or a
qual ified service stat ion.
If you choo se to cha nge yo ur oi l y ou rse lf, please no te the following
important information:
& WARNING
To reduce the risk of per sonal injury if you m ust change the engine
o il in you r veh ic le y our self :
• Wear eye protection.
• To reduce the ri sk of burn s from hot engine oil , let the engine
c ool down to the tou ch.
• When removing the oil drain plug with your fing ers , sta y as far
away as po ssi ble . Alw ay s k eep your f orearm par allel to the gr ound
to help pre vent hot oil from running down your arm .
• Drain t he oil int o a contain er de signed for thi s purpo se , one
large enough to hold at l ea st th e total amount of oil in your eng ine .
• Engine oil i s poi sono us. K eep it well out of the rea ch of ch ildr en .
• Continuou s contact with u sed engine oil i s harmful to your
sk in. Al wa ys prote ct you r ski n by washing oil off thoroughl y with
s oap and w ater.
0 Note
Never mix oil addi tives with your engine oil. These add itives can
damage your engine and adversely affect your Audi Limited New
Vehicle Warranty .
c£> For the sake of the environment
• Before changing your oi l, first make sure you know where you
can properly dispose of the us ed oil.
• Always dispose of used engine oil properly. Do not dump it on
garden soil , wooded areas, into open streams or down sewage
drains .
• Recycle used engine oil by taking it to a used engine oil collec ­
tion fac ility in your area , or contact a service station. •
Engine cooling system
Coolant
The engine coolant performs two functions: it keeps the
engine from overheating and it protects the engine from
freezing i n the winter.
The cooling system is sea led and generally requires little attention.
The coo ling system has been fi lled at the factory with a permanent
coolant which does not need to be changed . The coolant consists of
a mixture of water and the manufac turer's glycol-basedcoolant
additive G 12+ an tifreeze with anticorrosion additives (50% for USA
models; 60% for Canadian models). This mixture both assures the
necessary frost protection and protects metal components in the
engine 's cooling system from corrosion and scaling . It also raises
the boiling point of the coolant.
Do not reduce the concentration of the coo lant in the summer by
adding plain water.

Vehicle care
I t •

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
& WARNING (continued)
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­
ment (whether installed or not).
Aspect ratio means the ratio of the height to the width of the tire in percent.
Numb ers of 55 or lower indicate a low sidewall for improved
steering response and better overall handling on dry pavement.
Bead
means the part of the tire that is made of steel wires, wrapped or reinforced by ply cords and that is shaped to fit the rim.
Bead separation means a breakdown of the bond between components in the bead.
Cord
means the strands forming the plies in the tire.
& WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period
before the tire pressure is measured or adjusted .
Curb weight means the weight of a motor vehicle with standard equipment
including the maximum capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
Extra load tire
means a tire designed to operate at higher loads and at higher infla ­
tion pressures than the corresponding standard tire . Extra load tires
my be identified as "XL",
"xi", "EXTRA LOAD", or "RF" on the side ­
wall.
Gross Axle Weight Rating ("GAWR")
means the load-carrying capacity of a single axle system, measured
at the tire -ground interfaces .
Gross Vehicle Weight Rating ("GVWR"l
means the maximum total loaded weight of the vehicle.

& WARNING (continu ed )
• Only when all tires on the veh icle are filled to the correct pres­
s ure , the tire pre ssure monitoring sy stem can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage. Therefore it i s es sential that the driver observe
the specified tire pre ssure values for the tires and the correct pres­
s ures for the function of the tire pressure monitoring system.
• Alway s inflate tires to the recommended and correct tire pres ­
sure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot re sulting in tread separation , sudden ti re failure and loss
of control.
• Ex cessive speed and /overloading can cause heat build -up ,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well .
• If the tire is not flat and you do not have to change a wheel
immediately , drive at reduced speed to the nearest service stat ion
to che ck the tire pressure and add air as required .
0 Note
Driving without valve stem caps can cause damage to the tire
valves. To preven t this, a lways make su re t hat facto ry instal led
va lve
stem caps on a ll whee ls are securely mounted on the va lve .
'£> For the sake of the environment
Underinflated t ires will a lso increase the fuel consumption. •
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehicle and
any t ire can car ry. A vehicle that i s ove rlo aded wil l n ot hand le well and
is more difficu lt to stop . Overloading can not only lead to loss
o f ve h ic le control, but ca n also damage impor ta nt parts o f the
vehic le and can lead to sudden tire fa ilure, inc luding a blowout and
sudden defla tion that ca n cause the vehic le to cra sh .
Your sa fety and that o f your passe ngers also depe nds on mak ing
sure that load limits are not exceeded . Vehicle load includes every ­
b ody and everyth ing in and on t he veh ic le . T hese load lim its a re
technica lly referred to as the vehicle's
Gross Vehi cle We ight Rating
(" GVWR"l .
The "GVWR" includes the weight of the basic veh ic le, all factory
insta lled accesso rie s, a ful l tank of fuel , oil, coolant an d other fluids
p lus max imum load. T he ma xim um load inc ludes the number o f
passe ngers that the veh icle is intended to carry ("seat ing capacity")
w ith a n assu med we ight of 150 l bs (68 kg) fo r each passen ger at a
designated seating position and the total weight of any luggage in
the v ehicle. I f you tow a trailer, the we ig ht o f the tra ile r hi tch and t he
tongue weight of the loaded trailer must be includ ed as part of the
ve hicle l oad.
The
Gross Axle Weight Rating ("GAWR"l is t he maximum load that
can be applied at each of the vehicle's two ax le s.
The Gross Ve hicle We ig ht Rat ing and t he G ross A xle Weig ht Rat ing
are listed on the safety comp liance stic ker label located either on
t he d rive r's side 8 -p illar or on th e inside of the fuel fil ler fla p. You r
