2011 AUDI TT ROADSTER oil additives

182 Checking and filling
Deterge nt additives in the o il wi ll make fresh
oil look dark after the engine has been run­
n ing for a short time . This is norma l and is not
a reason to change the oil more often than recommended.
D am ag e o r m alfun ction s due to lack of
m ainten ance
It is essent ial that yo u change your oil at the
recommended intervals using only engine oil
that complies with Audi oi l standard
VW 502 00. Yo ur Limited New Veh icle War­
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty& Maintenance book let . Your dea ler will have to
deny warranty coverage un less you p resen t to
the dea ler proof in the form of Servi ce or Re­
pa ir Orde rs that all schedu led maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving ports.
I n o rder to prov ide effective lubr ication and
cooling of internal engine components, a ll in­
ternal comb ustion engines consume a certain
amount of oil. Oi l consumption varies from
engine to engine and may change significantly
over the life of the eng ine . Typically, eng ines
with a specif ied break-in period (see
c::;, page 157) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under normal conditions, the rate of oil con­
sumpt io n depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) at
which the engine is operated, the ambient
temperature and road cond it io ns. Furthe r fac­
tors are the amo unt of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is s ubject to
wear as mileage bui lds up, the oil consump­
tion may increase over t ime until replacement
of worn components may become necessary. Wi
th a ll these variab les coming into p lay, no
standard rate of oil consumption can be es­
tab lished or spec ified. There is no alte rnative
to regular and frequent check ing of the o il lev­
el, see
Note .
If the yellow engine oil leve l warning symbo l
in the instr ument cluster
m lights up, yo u
sho uld check the oil leve l as soon as possib le
with the oil dipstick c::;, page 183. Top off the
o il at your earliest conve nience
c::;, page 183 .
A WARNING
-Before you chec k anything in the engine
compartment, a lways read and heed a ll
WAR NIN GS
c::;, .& in Working in the engine
comportment on page 178.
CI) Note
D riving with an insufficient o il level is like­
l y to cause sever e damage to the engine.
(D Tips
- The oil pressure warn ing display. is
not an indicator of the oil level. Do not
re ly on it . Instead, check the oil level in
your engine at r egular interval s, pr ef­
erably e ach time you refu el, and always
before going on a long trip.
- If you have the impressio n yo ur engine
cons umes ex cessive amoun ts of oil, we
recommend that you consult your Aud i
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate meas urement of o il con­
sumption requ ires great care and may
take some t ime . Your Audi dea ler has in­
struct ions about how to measure oil con­
sumption acc urately.

184 Checking and filling
- If your skin has come in contact with the
engine oil, you must subsequent ly
cleanse it thoroughly.
- The oil level must not be above range
G)
-danger of converter or engine damage!
Contact an a uthorized dea lership to draw
off o il, if necessary.
- Audi does not recommend the use of o il
addit ives. They may damage the engine
and adve rsely affect you r New Vehicle
War ranty .
@i For the sake of the environment
-Under no circumstances can the oil come
i n contact with the sewage network or
the soil.
- Observe and follow lega l regu lations
when disposing of empty oil containers.
Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv­
ice station .
Before you check anything in the engine com­
partment,
always read and heed all WARN·
INGS
¢ .&. in Working in the engine comport·
menton page 178 .
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance book let . T his is very important
because the l ubricating prope rties of oil di­
minish gradua lly dur ing no rmal veh icle use .
Under some circumstances the engine o il
should be changed more frequently . Change
oil more often if you drive most ly short dis­
tances , ope rate the vehicle in dusty areas or
u nder predominantly stop -and-go t raffi c con­
d itions, or have your veh icle w here tempe ra ­
tures rema in below free zin g fo r ex tended pe­
riods .
D ete rge nt add it ives in the o il w ill ma ke fresh
oil look dark after the eng ine has been run­
n ing fo r a shor t time. This is no rm al and is not a
reason to change t he oil more often than
recommended.
B ecau se of the p rob lem of p roper dispos al,
along wi th the specia l tools and necessa ry ex ­
pert ise req uired, we st rongly recommend tha t
yo u have your oil changed by an a uthorized
Audi dealer or a qualified service station.
If you choo se to change your oil your self ,
please note the fo llowing important info rma ­
tion:
A WARNING
-To reduce the risk of pe rsonal in jury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot en-
g ine oil, let the engine cool down to the
touch.
- When removing the o il dra in p lug with
your fingers, stay as far away as possib le.
Always keep your forearm parallel to the
ground to help prevent hot oil from run·
n ing down your arm.
- Dra in the oil into a container designed
for this purpose, one la rge enough to
hold a t least the tota l amount of oi l in
your e ng in e.
- Engine oil is poisonous . Keep it we ll out
of the reach of childre n.
- Continu ous contact wit h used eng ine o il
is harmful to yo ur s kin. Always protec t
your skin by washing oil off tho ro ughly
wit h soap an d wate r.
(D Note
Never mix oil additives with your engine
o il. These additives can damage your e n·
gin e and adversely affect your Audi Limit­
ed New Veh icle Warranty.
@ For the sake of the environment
-Befo re changi ng your oil, first make s ure
you know where you can prope rly dispose
of t he used oil.
- Always dispose of used eng ine oi l proper -
ly. Do not dump it on garden soil,
IJJ,-

wooded areas, into open streams or
down sewage drains.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station.
Engine cooling system
Coolant
T he engine coolan t performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention .
T he cooling system has been filled at the fac­
tory with a permanent coolant which does not
need to be changed . The coolan t consis ts of a
mixture of water and the manufacturer 's gly ­
col-basedcoolant additive G12 ++ antifreeze
with anticorrosion additives (50% for USA
models; 60% for Canad ian models). This mix­
ture both assures the necessary frost protec­
tion and protects metal components in the
engine 's cooling system from corrosion and
scaling. It also raises th e boiling point of the
c oolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifree ze protection and cooling efficien­
cy . If the coolant frost protection is too low,
the coolant could freeze and damage the veh i­
cle heating and eng ine cooling system .
For year-round driving, an tifree ze is added at
the factory for temperatures down to:
- -31 ° F ( - 3 5 °C) USA
- -40 °F ( -40 °C) Canada.
You can mix the G12 ++ coolant addit ive with
other additives (G12+ or G12) . Always check
with your authorized Audi dealer.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
-
Checkin g and fillin g 185
WARNINGS c:::> .& in Working in the engine
compartment on page 178.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extreme ly cold . If necessary, in­
crease the proportion of coo lant add itive
to 60% .
- Whe n adding coolant additive to your
cooling system, remember :
- We recommend using only coo lant ad­
ditive G12++ (check the labe l) for your
vehicle . This coolant additive is avai la­
ble at authorized Audi dealers. Other
types of ant ifreeze can significantly re­
duce corrosion protection . The result­
ing corrosion can cause a loss of cool ­
ant and ser ious eng ine damage.
- Do not add any type of rad iator leak seal ­
ant to yo ur vehicle's engine coolant .
Add ing radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could resu lt 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.
