The engine oil used must conform to exact speci­
fications.
The service interval d isplay 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,

Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled with a h igh-quality oil
which can usually be used throughout the entire
yea r.
(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 qual ity eng ine 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.
@ 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 h igh-quality
"synthet ic"oil that meets the following speci­
fications.
- Vehicles w ith gasoline eng ine: 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 o il that
has been approved for your vehicle, please
contact either your authorized Audi dea ler
or Aud i Custome r Relat ions at
1 (800) 822- 2834 or visit ou r web site at
www.audiusa.com or www .aud icanada.ca.

· Eng ine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts.
In order to provide effect ive lubricat ion and cool­
i ng of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption var ies from engine to en­
gine and may change sign ificantly over the life of
the engine . T ypically, engines w ith a specified
break -in period (see¢
page 65) consume more
oi l during the break-in period than they consume
after oil consumption has stabilized.
U nder normal cond itions, the rate of oil con­
sumption depends on the quality and viscosity o f
the oil , the RPM (revo lutions per minute) at
which the engine is operated, the ambient tem­ perature and road conditions. Further factors are
the amount of o il dilution from water condensa­
tion or fuel residue and the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the o il consumption may increase over
ti me unt il replacement of wo rn compo nents may
become necessary.
With all these variables coming into play, no standard rate of o il consumption can be estab­
li shed or spec ified . T he re is no alte rnative to reg­
u la r and freq uent checki ng of the oi l level, see
Note.
If the yellow engine oil level warning symbo l II
in the instrument cluster lights up, you sho uld
chec k the o il level as soon as possible
¢
page 193. Top off the o il at your earlies t con­
venience
¢ page 193.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
¢page 188.
(D Note
Driving with an insufficient oil level is likely to
cause severe damage to the engine.
IJII,

Check ing and F illing
- After adding engine oil, the o il level must
not be above the marking@~
fig. 162, be­
cause this increases the risk of cata lytic con­
verter and/or eng ine damage. Do not start
the engine. Contact an authorized Audi
dealer or authorized Audi Service Fac ility to
have excess engine oil extracted if necessa­
r y .
- Do not mix any additional lubricants into
the engine o il. Damage cause by such addi­
tives is not cove red by the war ranty .
@ For the sake of the environment
-Engine o il should never enter the sewe r sys­
tem or come into contact with the ground
under any circumsta nces.
- Pay attention to legal requirements when
d ispos ing of empty oil containe rs .
(D Tips
The engine oil consumption may be up to 0.5
quart/600 m iles (0.5 liter/1,000 km), de­
pending on d rivi ng s tyle and operating condi­
tions. Consumption may be higher du ring the
fi rst 3,00 0 miles (5, 000 km). Be cause of this,
t he engine oil leve l m ust be chec ke d r egular ­
ly. It wo uld be best to check each time you re ­
fue l your vehicle and before long drives .
Changing the engine oil
We recommend that hove your oil changed by an
authorized Audi dealer or a qualified service sta ­
tion .
Before you check a nyth ing in the eng ine compart­
men t,
alway s read and heed all WARNINGS
~ page 188.
The engine oil must be changed accord ing to the
i n tervals specified in your Warran ty
& Mai nte­
nance booklet . This is very importan t because the
lubricating p roperties of o il diminish gradually
during normal vehicle use.
Under some c irc ums tances the eng ine o il sho uld
be changed more frequently. Change oil more o f­
ten if yo u drive most ly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic cond it ions, or have your vehi-
194
de where temperatures remain be low free zin g
for extended periods.
Dete rge nt additives in the oi l will make fres h oil
l ook dark a fter the engine has been r unning for a
short time . This is normal and is no t a reason to
change the oi l more often than recommende d.
Bec ause of t he pr oblem of prope r dispos al, along
with t he speci al tools and ne ce ssary expertise re­
quired, we strongly recommend that yo u have
your oi l changed by an authorized
Audi dealer or
a q ua lified serv ice station .
If you choo se to change your oil your self , please
note the fo llowing important information:
_& WARNING
To reduce the risk of persona l injury if you
must change the eng ine oil in you r vehicle
yourself:
- Wear eye protect ion .
- To reduce the r isk o f bu rns from hot engine
oil, let t he engine cool down to the touch.
-
- When removin g the oil dr ain plug with yo ur
