Engine oil
Engine oil specifications
The engine oil used in your Audi needs the right kind of
oil.
The engine in your Audi is a sophisticated powerplant that was built
to exacting specifications . This engine needs the right kind of
engine oil that meets specifications regarding quality and viscosity
so that it can run smoothly and reliably. Choosing the right oil and
changing oil within the time and mileage intervals printed in your
vehicle's Warranty
& Maintenance booklet matters a lot more today
than it did years ago. Audi has developed a special quality standard
for engine oil that will help assure that your vehicle's engine will get
the lubrication it needs for proper operation .
Modern engine lubrication has taken a quantum leap in the last few
years. Many synthetic oils available today provide better engine
lubrication that can outlast traditional petroleum-based oils,
making them a smart choice for use throughout the life of your Audi .
Whether you use synthetic or petroleum-based engine oil, the oil
that you use must conform to Audi's oil quality standard VW 502 00
to help keep your vehicle's engine running smoothly and help

the form of Service or Repair Orders that all schedu led maintenance
was performed in a time ly manner .•
Engine 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 197) consume
more oil during the break-in period than they consume af ter 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 the 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.
W ith all these variables coming into play, no standard rate of oil
consu mption can be estab lished or specified. There is no a lternative
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
poss ible
with the oil dipstick~ page 229 . Top off the oil at your
earliest convenience~
page 230.
& WARNING
Before you che ck anything in the eng ine comp artment , alw ay s
read and heed all WARNINGS
~ & in "Working in the engine
c ompartment " on
page 22 5.
0 Note
Driving with an insufficie nt o il level is l ikely to cause severe damage
to the engine.
[ i ] Tip s
• The oil pressure warning displ ay ce,. is not an indi cat or of the oil
level . Do not rely on it. Instead , check the oil level in your engine at
regular interv als , prefe rably ea ch time you refuel , and always before
going on a long trip.
• If you have the impression your engine consumes excessive
amoun ts of oil, we recommend that you consu lt your authorized
Audi dealer to have the cause of your concern proper ly diagnosed .
Keep in mind that the accura te m easuremen t of oil consumption
requires great care and may take some time . Your authorized Audi
dea ler has instructions about how to measu re oil consumption
accurately .•

Changing the engine oil
We recommend that have your oil changed by an autho­
rized Audi dealer or a qualified service station.
Before you check anything in the engine co mpart ment, always re ad
an d heed all WARN INGS=>
& in "Working in the engine compart­
ment" on
page 225.
The engine oi l must be changed according to the interva ls specified
in your Warranty
& Maintenance booklet. This is very important
because the lubricat ing properties o f oi l d im inish g radua lly during
normal vehicle use.
Under some circumstances the engine oil shou ld 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 freezing for extended periods .
Detergent additives in the oil w ill make fresh oi l 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 .
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 changed by an authorized
Audi de aler or a
qualified service station .
If you choose to ch ang e yo ur oil your self , please note the following

Engine cooling system
Coolant
The engine coolan t perf orms two func tions: it keeps the
engine from overheating an d it protects the engine from
freezing in the winter.
The cooling system is sealed and general ly requires litt le attention.
The coo ling system has been fi lled at the factory with a permanent
coo lant which does not need to be changed. The coolant consists of
a mixture of water and the manufacturer's glycol -basedcoolant
additive G12+ + antifreeze with anti corrosion additives (50% for USA
models; 60% for Canadian mode ls) . 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 boil ing point o f the coolant.
D o not reduce the concentration of the coo lant in the summer by
adding pla in water.
Th e proporti on of coolant additive must b e at
l e as t 50 % but not more than 60 %
to maintain antifreeze protection
and cooling efficiency . If the coolant frost protect ion is too low, the
coo lant could freeze and damage the vehicle heating and engine
coo ling system.
For year-round driving, antifreeze is added at the factory for temper ­
atures down to :
• -31 °F ( -35 °C) USA
• - 40 °F ( - 40 °C) Canada .
You can mix the G12 ++ coolan t additive with other additives G12 + or
G12. Always check with your authorized Audi dealer.
& WARNING
Bef ore you che ck anything in the engine compartment , alwa ys
read and heed all WARNING S

Checking and filling -
---------------------=----"=---------
0 Note
• Before winter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especially important if you live in a region where
the winter is extremely cold. If necessary, increase the proportion of
coolant additive to 60%.
• When adding coolant additive to your cooling system,
remember:
-We recommend using only coolant additive G12+ + (check the
label) for your vehicle. This coolant additive is available at autho­
rized Audi dealers. Other types of antifreeze can significantly
reduce corrosion protection . The resulting corrosion can cause a
loss of coolant and serious engine damage .
• Do not add any type of radiator leak sealant to your vehicle's
engine coolant. Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and could result
in damage not covered by your New Vehicle Limited Warranty .•
Checking the engine coolant level
The engine coolant level can be checked with a quick
glance.
Fig . 175 Engine
compartment : coolant
expansion tank
Before you check anything in the engine compartment,
always read and heed all WARNINGS==> & in "Working in
the engine compartment" on
page 225.
Turn off the ignition.
Read the engine coolant level from the coolant expan­
sion tank==> fig. 175. With a cold engine, the coolant level
should be between the "min" and "max" markings. When
the engine is warm, the level may be slightly above the
" max" marking.
The location of the coolant expansion tank can be seen in the
engine compartment illustration=>
page 226.
To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehicle is equipped with an electric
coolant level sensor.
When the coolant level is too low, the warning light in the Auto­
Check System =>
page 30will blink until you add coolant and the
level has been restored to normal. Even though there is an electric
coolant level sensor, we still recommend you check the coolant level
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling system. In the event
of coolant loss, the cooling system should be inspected immedi­
ately by your authorized Audi dealer. It is not enough merely to add
coolant.
In a
sealed system, losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating.
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coolant. Adding radiator repair fluid may adversely affect the tune- _..
