2011 AUDI TT ROADSTER fuel additives

-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time .
(D Note
-Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system .
- Do not use fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility 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 prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac ­
turers is carbon deposit build- up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and
Fuel supply and filling your fuel tank 175
fuel systems clean, they are not equally effec ­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadequate
fuels, built-up carbon deposits can rob yo ur
engine of peak performance.
Q) Note
Damage or malfunction due to poor fue l
quality is not covered by the Aud i New Ve­
hicle Limited Warranty.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel fille r flap.
If the unlocking system should fail, you can
still open the flap manually -for detailed in ­
structions see ¢
page 177.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢ page 239.
The label on the inside of the fuel fi ller flap
tells you the correct fue l for your vehicle. For
more information about fuel specifications,
see ¢
page 174.
Your vehicle fue l tank has an on -board refue l­
li ng vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle . In order to fill the tank
properly while protecting the environment,
please fo llow this refueling procedure careful­
ly.
_&. WARNING
Under normal operating conditions, never
carry additional fue l conta iners in yo ur car.
Gas canisters and other containers used to
transport f uel can be dangero us. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision. If you must

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.
