2015 AUDI S3 SEDAN oil additives

fill up at busy gas stations where the seasonal
adjustment is more likely to be made in time.
(D Note
- Methanol f uels which do not meet these re­
quirements may cause corrosion and dam ­
age to plastic and rubber components in the
fuel system.
- Do not use fue ls that fail to meet the speci­
fied criteria in this chapter.
- If you are unable to determine whethe r o r
not a particular fue l blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Vehicle or the Emission Control
System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel b lends, we
recommend that you sw itch to unb lended
fuel.
Gasoline additives
A ma jor concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasol ine grades differ from one manu­
facture r to another, they have certa in things in
common . All gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. A l­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas ­
oline. For more information on TOP TIER Deter-
"' gent Gasoline, please go to the off icial webs ite

After an extended period o f using inadeq uate
fuels, carbon deposit build-ups can rob your en­ gine of peak performance .
(D Note
Damage or malf u nction due to poor fuel qual ­
ity is not cove red by the Audi New Vehicle
Limited Wa rranty.
Diesel fuel
Applies to vehicles: with diesel engine
Always use ULSD (Ultra Low Su lfur Diesel) No. 2 .
The ULSD No. 2 meets the ASTM 0975.
Diesel fuel w ith concen tra tions of biodiese l hig h­
er than 5
% such as Bl 1, B20 or 8100 are strictly
prohibited .
Se rv ice stat io n fue l pumps a re labe led with the
correct fue l information for easy recognit ion by
the user .
If the diese l fue l pump is not labe led
ask the station operator w hat fue l is being dis­
pensed before fi lling up your vehicle.
UL SD No. 2 may not be available outside the USA
and Canada . Be sure to check before traveling to
other countr ies .
UL SD No. 2 can become thicke r in very cold tem­
pera tures, and th is can impa ir t he engine's start­
ing and running. Depending on the season, gas
stations provide ULSD No . 2 that flows better in
cold temperatures so that you can continue oper­
at ing your vehicle as usual.
@ Note
- Yo ur vehicle's diesel engine was designed
soley for use with ULSD No. 2. Therefore,
never use gasoline, heating oil, other fuels
or flow improvers. These conta in substances
that will severe ly damage the fuel system
and the engine . Such damage will not be
covered by you r New Veh icle Limited War­
ranty.
- If you put any amount of incorrect fuel i n
the fuel tank, do not start the eng ine under
any circumstances. Immediate ly co ntact t he

Checking and Filling
"' Check the oil level again after two minutes
¢ page 203 , Checking the engine oil level.
"'Add oil, if necessary.
"'Close the engine oil filler cap and push the dip­
stick all the way in.
A WARNING
- When adding oil, do not let oil drip onto hot
engine components. There could be risk of a
fire.
- You must secure the cap on the oil filler
opening correctly so that oil does not leak
out onto the hot engine and exhaust system
when the engine is running, because this is
a fire hazard.
- Always clean skin thoroughly if it comes into
contact with engine oil.
(D Note
- Applies to vehicles with gasoline engines:
the oil level cannot be above the
0 range
¢ page 203, fig. 159, because this can
cause damage to the catalytic converter or
the engine. Contact an authorized Audi
dealer or authorized Audi Service Facility to
have excess oil extracted if necessary.
- Applies to vehicles with diesel engines: the
oil level must not be in the
(v range
¢ page 203, fig. 160 -The oil must not be
extracted, because this can damage the en­
gine. Drive to an authorized Audi dealer or
authorized Audi Service Facility immediate­ ly .
- Do not mix any additional lubricants into
the engine oil. Damage cause by such addi­
tives is not covered by the warranty.
@ For the sake of the environment
- Oil should never enter the sewer system or
come into contact with the ground.
- Pay attention to legal requirements 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 service sta­ tion.
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
¢ page 198.
The engine oil must be changed according to the
intervals specified in your Warranty & Mainte­
nance booklet . This is very important because the
lubricating properties of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oil should
be changed more frequently. Change oil more of ­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
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 special tools and necessary expertise re­
quired, we strongly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station.
If you choose to change your oil yourself , please
note the following important information:
A WARNING
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
-
- To reduce the risk of burns from hot engine
oil, let the engine cool down to the touch.
- When removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.

These additives can damage your eng ine and
adversely affect your Audi Limited New Veh i­
cle Warranty .
@) For the sake of the environment
-Before changing your oi l, f irst make sure
you know where you can properly dispose of
the used oil.
- Always d ispose of used engine oil proper ly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
d rains .
- Recycle used e ngine oi l by taking it to a used
engine oil collection facility in your area, or
contact a service station .
Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter.
The cooling system is sea led and generally re ­
q ui res lit tle atten tion.
The cooling system has been filled at the factory
w ith a pe rma nen t coolan t which does no t need to
be ch anged . T he coolant consists o f a mixture o f
specia lly condit ioned wa ter and the man ufactu r­
er's glycol -based coolant additive Gl3 antifreeze
with anticor rosion add itives (SO% for USA mod­
e ls · 60% for Canadian models) . Th is m ixture bot h

system from corrosion and scaling . It also raises
t h e boiling point of the coo lant .
D o no t redu ce the con cen tra tion of the coolan t in
the summer by ad ding plain water.
The prop or­
tion of coolant additive mu st be at least 50%
but not more than 60%
to maintai n antifr eeze
protection and cooling efficiency . If the coo lant
frost pro tec tion is too low, the coo lant co uld
freeze and damage the vehicle heating and en­
gine cooling system .
For year- ro und driving, antifreeze is added at the
factory for temperatures down to :
-- 31°F(-3S° C)USA
- -40 °F ( - 40 ° C) C anada.
If you must add coolant, use a mixture of water
and coolant additiv e. Mix ing the coo lant add it ive
with dis tilled wa te r is recommended .
A WARNING
Befo re you c hec k anythi ng i n the engi ne com ­
partment, always re ad and heed a ll WA RN­
IN GS
~page 198.
(D Note
- Befor e wi nter sets in , have the coo la nt
c hecke d to see if the cool an t additive in you r
vehicle is sufficient to meet the climate con ­
ditions . This is espec ia lly impo rtant if you
live in a region where the winter is extreme ­
ly cold . If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to yo ur cool ­
ing system, remember:
- We recommend us ing o nly coo la nt addi­
tive G12 ++ o r G13 ( che ck the label) fo r
your ve hicl e. This coolant addi tive is av ail­
a ble at autho rized Aud i dea le rs . Othe r
types of ant ifreeze can significant ly re­
d uce corrosion protection. The resulting
corrosion can ca use a loss o f coolant and
serious engine damage.
- Do not add any type of rad iator leak sealant
to y our vehicle's engine coolant. Adding ra­
diator repa ir fluid may adversely affect the
function and perfo rmance of your cooling .,,.
