Engine oil
Engine oil specificat ions
The engine oil used must conform to exact speci
fications .
The service interval display in the instrument
cluster of your vehicle will inform you when it is
time for an oil change . We recommend that you
have your oil changed by an authorized Audi Serv
ice Advisor.
If you have to top off the oil between oil changes,
use the Audi oil quality standard specified in the
table.

Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled with a high-quality oil
which can usually be used throughout the entire
year.
(D Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet.
- Use only a high quality engine oil that ex-
pressly complies with the Audi oil quality
standard specified for your vehicle's engine .
Using any other oil can cause serious engine
damage.
- Do not mix any lubricants or other additives
into the engine oil. Doing so can cause en
gine damage.

(D Tips
If you need to add oil and there is none availa
ble that meets the Audi oil quality standard
your engine requires, you may add a total of
no more than 0.5 quart/liter of a high-quality
"synthetic"oil that meets the following speci
fications.
- ACEA A3 or API SM with a viscosity grade of
SAE OW-30, SAE 5W-30 or SAE 5W-40.
- For more information about engine oil that
has been approved for your vehicle, please
contact either your authorized Audi dealer
or Audi Customer Relations at

Engine oil consumption
The engine in your vehicle depends on on ade
quate amount of oil to lubricate and cool all of
its moving ports.
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 en
gine and may change significantly over the life of
the engine. Typically, engines with a specified break-in period (see
¢ page 142) consume more
oil during the break-in period than they consume
after oil consumption has stabili zed.
Under normal conditions , the rate of oil con
sumption depends on the quality and viscosity of
the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient tem perature and road conditions . Further factors are
the amount of oil dilution from water condensa
tion or fuel residue and the oxidation level of the
oil. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time until replacement of worn components may
become necessary.
With all these variables coming into play, no
standard rate of oil consumption can be estab
lished or specified. There is no alternative to reg
ular and frequent checking of the oil level, see
Note.
