2008 AUDI S8 recommended oil

___ C_ h_e _c _ k_ i_ n ~g~ a_ n_ d_ f_ i_ll _in _g~--------------------------------------------
to help keep your vehicle's engine running smoothly and help
prevent the formation of harmfu l deposits, sometimes called
"sludge, " that over time can lead to expensive repairs .
At the time of printing, engine oils available in the U.S. and Canada
that meet the exacting specificat ions of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oi l standard VW 502 00. So
a lways b e sur e that you use an approved oil.
To help prevent the formation of harmful deposits use only oi l with
the following specifications printed on the oil container :
Audi oil sta nda rd VW 502 00
Oil container labels may carry the specification singly or in combi­
nation with other designations and oil quality standards.
V iscosi ty
Engine oi ls are graded according to their viscosity . The proper
viscosi ty grade oi l for your engin e depends on climactic or seasonal
conditions where you drive . You can use o il with a v iscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi­
tions.
However , if eng ine oil viscosity grade SAE 5W40 is not available, you
can a lso use viscosity grade SAE 5W -30 or SAE 0W -40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
B ecause engin e oil that meets the Audi oi l standard may not be
avai lable everywhere when you need it, we strongly recommend
that you a lways carry with you an extra quart !liter) of oil that
express ly conforms to t he VW 502 00 specification, in case you have
to top off the oil while on the road.
Only if th e level of the oil is at or be low the minimum mark on the
oi l dipstick -and no oil that express ly conforms to Audi oi l standard
VW 502 00 specifications is avai lable -may you top off with a high
quality engine oi l, preferably synthetic -based, that meets ACEA A3,
ACEA A5 or ACEA B5, API SL or ILSAC GF -3 specifications , but even
t hen, only in viscosity grades SAE 5W -40, SAE 5W -30, or SAE 0W -40.
However, during the entire time betwe en oil change int erva ls, nev er top off with more than a total of 0
.5 qt/ liter engine oil that does not
conform to Audi oil specifica tion VW 502 00.
For more information about engine oil that has been approved for
your vehic le, please contact either your authorized Audi dealer or
Aud i Customer Relat ions at 1 (800) 822-2834 or v isit our web s ite at
www.audiusa.com or www.audicanada.ca. Here you will also find a
current list of o ils (manufacturers, brand names
etc.I that conform
to Audi oi l standard VW 502 00.
Ch an g in g t he en gin e oil
The engine oil and o il filter must be changed according to the
mileage (ki lometers) and time intervals specified in your vehic le 's
Warranty & Maintenance booklet . Do not exceed these intervals -
harmful deposits from old engin e oil can reduce engin e perfor­
mance and can lead to expensive eng ine repa irs.
Changing the oil at the recommended intervals is so very impor tant
because the lubricating properties of oi l decrease gradua lly during
normal vehicle use. If you are not sure when you have your o il
changed, ask your authorized Audi Service Advisor.
Under some circumstances the eng ine oil should even be changed
mor e frequen tly . Change oil more oft en if you drive most ly short
distances, operate the vehicle in dusty areas or mostly under stop ­
and -go traffic conditions, or when you use your vehicle where
t emperatures stay be low freezing po int for long per iods .
Detergent add it ives in the oi l wi ll make fresh oil look dark after the
engine has be en running for a short time. This is normal and is not
a reason to change the oi l more often than recommended .
Dam age or malfun ction s du e to lack of m aint enan ce
It is essential that you change your oil 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 malfunctions due to fai lure to follow recommended
maintenance and use requirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet. Your dea ler wi ll have
to deny warranty coverage un less you pr esent to the dea ler proof in

Changing the engine oil
We recommend that have your oil changed by an auth o­
rized Audi dealer or a qualified service station.
Before you check anything in the engine compartment, always rea d
and heed all
WARNING S=> & in "Working in the engine co mpart­
ment" on
page 307.
The engine oi l must be changed according to the interva ls specified
in your Warranty
& Maintenance booklet . This is very important
because the lubricating properties of oi l diminish gradua lly during
normal vehicle use.
Under some circumstances the engine oil shou ld be changed more
frequently . Change oil mo re often if you drive most ly short
distances, operate the vehicle in dusty areas or under predomi­
nantly stop -and -go traffic conditions, or have your ve hicle where
temperatures remain below freezing for extended periods.
Detergent additives in the oil will make fresh oi l look dark after the
eng ine has been runn ing for a short t ime . Th is is normal and is not
a reason to change the oil more often than recommended .
Because of the problem of proper disposal, along with the spec ial
tools and necessary expertise required, we strong ly recommend
that you have your oi l ch anged by an authorized Audi dealer or a
qualified service station .

Vehicle care

Tires and wheels -
----------------
•
& 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 design to operate at higher loads and at higher infla ­
tion pressures than the corresponding standard tire. Extra load tires
may 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")
means the maximum total loaded weight of the vehicle.
