Fuel supply and filling your fuel tank
Blend of gasoline and MTBE
• Anti-knock index must be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform especially well fo r
winter or summer driving. During seasonal change-over, we suggest
that you fill up at busy gas stat ions where the seasonal adjustment is
more likely to be made in time.
0 Note
• Methano l fuels which do not meet these requirements may cause
corrosion and damage to plastic and rubber components in the fue l
system .
• Do not use fuels that fail to meet the specified criteria in this
chapter .
• If you are unab le to determine whether or not a particu lar fuel
blend meets the spec ifications, ask your serv ice station or its fuel
supplier.
• 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 responsi­
bility of Aud i and are not covered under the New Vehicle or the Em is­
sion Control System Warranties.
• If you experience a loss of fuel economy or driveab ility and perfor­
mance problems 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 manufacturers 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 gaso line g rades contain
substances that can cause deposits to collect on v ital engine parts,
such as fuel injectors and intake valves. A lthough most gasoline
brands include additives to keep eng ine and fuel systems clean, they
are not equally effective.
Audi recommends using TOP TIER Detergent Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the officia l
webs ite (www.toptiergas.com).
After an extended period of using inadequate fuels, carbon deposit
build-ups can rob your engine of peak performance.
0 Note
Damage or malfunction due to poor fuel quality is not covered by the
Audi New Vehicle Limited Warranty. •
Fuel tank
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~
page 277.
You can find the fue l tank capacity of your vehicle in
Technical Data
~page 343.
The label on the inside of the fuel filler flap tells you the correct fuel
for your ve hicle. For more information about fuel specifications, see
~page 273.
Your vehicle fuel tank has an on-board refue lling vapor recovery
system. This feature helps to prevent fuel vapors from escaping from
the tank and polluting the environment wh ile you refuel your veh icle . ..,_

Engine oil
Engine oil specifications
The engin e oil used in your Audi needs the right kind of oil.
Th e e ng ine in your Aud i is a sophis ticated powerplant that was bui lt
to exacting spec ificat ions. This engine needs the r ight kind of engine
oil t hat meets spec ifi cat ions regarding qu ality a nd viscosity so t hat it
can run smooth ly and re liably. Choosing the right o il and changing oil
with in the time and mileage intervals pr in ted in your veh icle 's
Warranty
& Maintena nce book let matters a lot more today than it did
years ago . Audi has developed a specia l quality standard for engine oil
that w ill help assure that your veh icle's engine will get t he lubr ication
it needs fo r prope r operation.
M ode rn engine lubr ication has taken a quan tum leap in the last few
years. Many synthet ic oils available today provide better engine lubri­
c at ion th at c an outlast tradit ional petro le u m-based o ils, making
them a smart choice for use throughout the life of your Aud i.
Whethe r you use synthetic or petroleum -based engine oi l, the o il th at
yo u use mus t confo rm to Aud i's oi l quality standa rd VW 502 00 to
help keep your ve hicle's engine runn ing smooth ly and help prevent
the format ion of ha rmfu l deposits, somet imes called "sludge," t hat
over time can lead to expens ive repairs.
A t the time o f pr int ing , engine o ils avai lab le in the U.S . and Can ad a
that meet the exact ing spec ificat io ns of A udi o il standard VW 502 00
are syn the tic engine o ils . Thi s does not mean, however, that every
syn the tic engine o il will meet Aud i o il sta ndard VW 502 00. So a lways
be s ure that you use an app roved o il.
Safety first
To help prevent the format io n of harmfu l deposits use only oi l with
t he follow ing s peci ficati ons p rin ted on the oil con tainer:
Audi oil standard VW 502 00
Oil container labe ls may carry the specification s ingly or in comb ina­
t ion wi th o ther d esigna tions and o il quali ty stand ards.
Viscosity
Engine oils are g raded acco rdi ng to the ir viscosity . The proper
viscos ity grade oi l for your eng ine depends o n climac tic or seasona l
conditions where you drive. Yo u can use oi l with a v iscosity grade o f
SA E SW 40 acros s all t empe rature range s fo r no rma l dr iving con di­
tions.
However, if engine oil v iscosity grade SAE SW 40 is not ava ilab le, yo u
can a lso use viscos ity grade SAE SW -30 or SAE OW -40 as long as it
meets Audi oi l quality stan dard VW 502 00 specifications .
Be ca use e ngine o il th at mee ts the Aud i oil st andar d m ay not be avail ­
able everywhere when you need it, we strongly recommend that you
alw ays car ry w it h you an ex tra quart (lite r) o f oil that expressly
conforms to the VW 502 00 specification, in case you have to top off
t he o il w hil e on the road.
Only if t he level of the oil is at o r below t he min imum mark on the o il
dipstic k -and no oil that exp ress ly conforms to A udi oi l standar d
VW 50 2 00 sp ec ificat ions i s available -may you top off w it h a high

Changing the engine oil
The engine oil and oil fi lter must be changed according to the mileage
(kilometers) and t ime intervals specified in your vehicle 's Warranty
&
Maintenance booklet . Do not exceed these interva ls -harmful
deposits from o ld engine oil can reduce engine performance and can
lead to expensive engine repairs .
Changing the oil at the recommended intervals is so very impo rtant
because the lubricating properties of o il decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your author ized Audi Service Adv isor .
Under some circumstances the engine oil should even be changed
mo re frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where temper­
atures stay be low freezing point for long periods.
Detergent addit ives in the oi l wi ll make fresh oil look dark after the
engine has been running for a short t ime. 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 intervals
using only engine oi l that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle War ranty does not cover
damage or malfunctions due to fai lure to follow recommended main­
tenance and use requirements as set forth in the Audi Owner 's
Manual and Warranty
& Maintenance booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in
the form of Serv ice or Repair Orders that all scheduled maintenance
was performed in a time ly manner. •
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
eng ine components, all inte rnal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change sign ifican tly over the lif e of the engine. Typically,
engines with a specified break- in period (see~
page 251) consume
more oil during the break-in period than they consume after oil
consumption has stab ilized .
Under normal conditions, the rate of oil consumption depends on the
quality and viscosity of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water
condensation or fuel residue and the ox idation level of the oil. As any
eng ine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variab les coming into play, no standard rate of oil
consumption can be established or specified . There is no alternative
to regular and frequent checking of the oil level , see
Note .
If the yellow engine oil leve l warning symbol in the instrument
cl uster lights up, you should chec k the oil level as soon as possible
with the oil dipstick~ page 283. Top off the oil at your earliest
convenience ~
page 284.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Working in the engine
compartment" on
page 279.

Oil level within range
©
- You must add oil. Afterwards, the oil level should be
within range@.
The oil level needs to be checked at regular intervals . The best times
to do this are whenever you refuel and prior to long trips.
Depending on the way the vehicle is driven and the operating condi­
tions, oil consumption can be up to 1 quart per 1.200 miles
(l liter
per 2,000 km). Consumption may be higher within the first 3 ,000
miles (5,000 km) .•
