2015 AUDI A3 fuel additives

Many gasoline grades are blended to perform
especially well for winter or summer driving. During seasonal change-over , we suggest that
you fill up at busy gas stations where the sea­ sonal adjustment is more likely to be made in
time.
Q;) 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 fuels that fail to meet the
specified criteria in this chapter .
- If you are unable to determine whether
or not a particular fuel blend meets the
specificat ions, ask your service station or
i ts 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
lems 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 cer tain
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 systems clean, they are not equally effec­
tive.
Checking and Filling 207
Audi 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, carbon deposit build-ups can rob your engine of peak performance.
CJ) Note
Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system should fail, you
can still open the flap manually -for detailed
instructions see
c::> page 209.
You can find the fuel tank capacity of your ve ­
hicle in
c::> page 266.
The label on the inside of the fuel filler flap
tells you the correct fuel for your vehicle. For
more information about fuel specifications,
see
c::> page 206 .
Your vehicle fuel tank has an on board refuel­
ling 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 follow this refueling procedure careful­
ly .
A WARNING ~
Under normal operating conditions, never
carry additional fuel containers in your car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision . If you must
transport fuel to use for your lawn mower, ..,.

214 Checking and Filling
you have your oil changed, ask your author­
ized Audi Service Advisor.
Under some circumstances the engine oil
should even be changed more frequently .
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
ditions, or when you use your vehicle where
temperatures stay below freezing point for
long periods .
Detergent additives in the o il wi ll make fresh
oil look dark after the engine has been run­
ning for a short time. This is normal and is not
a reason to change the oil more often than recommended .
Damage or malfunctions due to lack of
maintenance
It is essential that you change your oil at the
recommended interva ls using only engine oil
that complies with Audi oil standard
VW 502 00. Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to fa ilure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet . Your dea ler will have to
deny warranty coverage un less yo u present to
the dea ler proof in the form of Service or Re­
pair Orders that all schedu led maintenance
was performed in a timely manner.
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
cooling of internal engine components , a ll in­
ternal combustion eng ines consume a certain
amount of o il. Oil consumption var ies from
engine to engine and may change significantly
over the life of the eng ine . Typically, engines
with a specif ied break-in period (see
¢
page 193) consume more oil during the
b reak-in period than they consume after oil
consumption has stabilized. Under
normal conditions, the rate o f oil con ­
s u mption depends on the quality and viscosity
of the oil, the RPM (revolut ions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac­
tors are the amount of oil dilut ion from water
co nd ensat ion or fuel residue and the oxida­
t ion level of the oil. As any engine is subject to
wea r as mileage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into play, no
standard ra te of oil consumpt io n can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the oil lev­
el , see
Note.
If the yellow engine oil leve l warning symbo l
Ill in the instr ument cl uster light s up, you
shou ld check the oil leve l as soon as possible
¢
page 215. Top off the oil at your earliest
convenience
~ page 215.
A WARNING
-~
Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
page 210.
(D Note
Driving wit h an insufficient oil level is like­
l y to cause severe damage to the engine.
(D Tips
-The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead, check the oil level in
your engine at regular intervals, pref­
erably each time you refuel, and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amounts of oil, we
recommend that you consult an author­
ized Aud i dea ler to have the cause of
your concern properly diagnosed. Keep in
mind that the accurate measurement of
oil consumption requ ires great care and
may take some time. An authorized Audi ..,.
