2000 AUDI ALLROAD fuel

Fuel supply
..:lib Use only unleaded fuel in your
�v ehicle.
Fuel Recommendation
The fuel recommended for your ve­
hicle is unleaded premium grade
gasoline with a minimum octane rat­
ing of 91 AK PI/9 5 RON or higher.
The recommended gasoline octane rating
for your engine can also be found on a label
lo �ated on the inside of the fuel filler flap.
Th1s rat1ng may be specified as AKI or RON.
Yo ur vehicle may also be operated using un­
leaded regular gasoline with a minimum oc­
tane rating of 87 AKI /91 RON. However,
using 87 AKI I 91 RON octane fuel will lead
to a cert ain loss of engine power.
1l =(R+ Ml/2 Notes
• Do not usa any fuel with octane
ratings lower than 87 AKI or 91 RON
otherwise expansive engine damage
will occur.
• Do not use leaded gasoline!
The use of leaded gasoline will se­
verely damage your vehicle's cata­
lytic converter and its ability to con­
trol exhaust emissions.
Unleaded gasoline is available throughout
the USA, Canada, and in most European
countries. We recommend that you do not
take your vehicle to areas or countries
where unleaded gasoline may not be avail­
able. VE

Octane rating
Octane rating indicates a gasoline's ability
to resist engine damaging "knock" caused
by pre-ignition and detonation. Therefore
�uying the correct grade of gasol ine is ve r-{
Important to help prevent possible engine
damage and a loss of engine performance.
Gasolines most commonly used in the
Uni ted States and Canada have the follow­
ing octane ratings that can usually be found
on the filler pump:
Premium Grade: 91 - 96 AKI
Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Knock Index =
(R+M) I 2 = (RON+MON) I 2
RON = Research Octane Number
MON = Motor Octane Number.

CARE-------------------------
Use of gasoline containing alcohol
or MTBE (methyl tertiary butyl
ether)
You may use unleaded gasoline blended
with alcohol or MTBE (commonly referred
to as oxygenates) if the blended mixture
meets the following criteria:
Blend of gasoline methanol (wood
alcohol or methyl alcohol)
Anti-knock index must be 87 AKI or
hig her.
Blend must contain no more than 3%
methanol.
- Blend must contain more than 2% CO­
solvents.
226 Note
Methanol
fuels which do not meet
these requirements may cause cor­
rosion and damage to plastic and
rubber components in the fuel sys-
tem. ·
Blend of gasoline and ethanol (grain
alcohol or ethyl alcohol)
Ant i-knock , index must be 87 AKI or
high er.
Blend must not contain more than 1 0%
ethanol.
Blend of gasoline and MTBE
- Anti-knock index must be 87 AKI or
hig her.
Blend must contain not more than 15%
MTBE. Notes
• Do not use fuels that fail to meet
the specified criteria in this chapter.
• If you are unable to dete rmine
whether or not a particular fuel
blend meets the specifications, ask
your service station or its fuel sup­
plier.
• Do not use fuel for which the con­
tents cannot be identified.
• Fuel system damage and perfor­
mance 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 drivea bility and perfor­
mance problems due to the use of
one of these fuel blends, we recom­
mend that you switch to unblended
fuel.

CARE
Seasonally adjusted gasoline
Many gasolines are blended to perform es­
pecially well for winter or summer driving.
During seasonal change-over , we suggest
that you fill up at busy gas stations where
the seasonal adjustment is more likely to be
made in time. Gasoline
additives
A major concern among many auto
manufacturers is carbon deposit build-up
caused by the type of gasoline you use.
Although gasolines differ from one
man ufacturer to another, they have certain
things in common. All gasolines contain
properties that can cause deposits to col­
lect on vital engine components, such as
fuel injectors and intake valves. Although
most gasoline brands include additives to
keep engine and fuel systems clean, they
are not equally effective.
After an extended period of using inade­
quate fuels, built-up carbon deposits can
rob your engine of peak performance. Note
Damage or malfunction due to poor
fuel quality is not covered by the
Audi New Vehicle Limited Warranty.

Maintenance
Yo ur vehicle has been designed to help
keep maintenance requirements to a mini­
mum.
However. a certa in amount of regular main­
tenance is still necessary to assure your ve­
hic le's safety, economy and reliabili ty.
c£> By regularly maintaining your
vehicle, you help make sure that
emission standards are maintai ned,
thus minimizing adverse effects on
the envir onment.
For detailed vehicle maintenance consult
your Maintenance booklet.
Under difficult operating condi­
tions, for example at extremely low out­
side temperatures, in very dusty regions,
when towing a trailer very frequently, etc.,
some service work should be performed
between the intervals specified.
This applies particularly to:
• oil changes, and
• cleaning or replacing the air filter.
228 Important
considerations for
you and your vehicle:
The increasing use of electr onics, sophisti­
cated fuel injection and emission control
systems, and the generally increasing tech­
nical complexity of today's automobiles,
have steadily reduced the scope of mainte­
nance and repairs which can be carried out
by vehicle owners. Also, safety and en­
vironmental concerns place very strict
limi ts on the nature of repairs and adjust­
ments to engine and transmission parts
which an owner can perform . Main
tenance, adjustments and repairs usu­
ally require special tools, testing devices
and other equipment available to specially
trained workshop personnel in order to as­
sure proper performance, reliability and
safety of the vehicle and its many systems.
Impr oper maintenan ce, adjustments and
repairs can impair the operation and reliabil­
ity of your vehicle and even void your ve­
hicle warranty. Therefore, proof of servicing
in accordance with the maintenance
schedule may be a condition for upholding
a possible warranty claim made within the
warranty period.
Above all, operational safety can be ad­
versely affected, creating unnecessary
risks for you and your passengers.

HICLE CARE---------------------------------------------------
Engine oil
Specification and viscosity
Yo ur engine was factory filled with an all
season high quality engine oil. If you need to
add oil between oil changes, use any high
quality petroleum- or synthetic-based oil
with correct specifications.
The following terms must appear on the oil
conta iner singly or in combination with oth­
er designations:
- API Service SJ
- ACEA A2 or ACEA A3
Engine oils are graded according to their vis­
cosity. The proper grade to be used in your
engine depends on existing climatic or sea­
sonal conditions.
The engine oil which was first put into your
engine has a viscosity grade of SAE OW--30.
You can use this oil over all temperature
ranges for normal driving. If engine oil vis­
costy grade SAE OW--30 is not available, you
can also use SAE 5W-30 or SAE 5W-40.
See your authorized Audi Dealer tor more in­
formation regarding oil for your vehicle.
234 I
B31-113C I
Engine oil identification symbol
Oils of the proper qualityforyour vehicle will
be identified with a new "starburst" sym­
bol A. The starburst symbol indicates that
the oil has been certified by the American
Petr oleum Institute (API). Another
oil identi fication symbol B could be
added to the oil container to help you select
the correct oil.
1 - The top portion indicates the oil quality
by API designations.
2 - The center portion shows the SAE oil
viscosity grade.
3- The lower portion indicates that the oil
has fuel saving capabilities.
Note
Look for one of these symbols on the
front of the oil container. and use
only oils that display these symbols.
Engine oil additives
Audi does not recommend the use of
oil additives. They may adversely af­
fect your New Vehicle Warranty.

Engine
oil consumption
The rate of the oil consumption depends on
the quality and viscosity of oil, the speed at
which the engine is operated, the climate,
and road conditions as well as amount of
dilution and oxidation of the lubricant.
Because of these variables, no standard
rate of oil consumption can be established,
but drivers should expect higher oil con­
sumption at high speeds and when the en­
gine is new.
Therefore, we recommend that you check
the oil level at regular intervals (for example,
each time you are refuelling, or before going
on a long trip).
If the oil level should go below the minimal
level, the check engine oil level warn­
ing light* in the instrument cluster will
come on. See page 144. You should check
the oil level using the oil dip stick as soon as
possible, and then top off the oil as neces­
sary. Notes
• The engine in your vehicle de­
pends on oil to lubricate and cool all
of its moving parts. Therefore the
engine oil should be checked regu­
larly and kept at the required level.
• Lack of sufficient engine oil may
lead to severe engine damage.
• The oil pressure warning light is
not an oil level indicator.
A Always
heed all WAR NINGS
� on page 232.
Checking the engine oil level
The best time to check the engine oil level
is when the oil is warm.
To get a true reading, the vehicle must be on
level ground.
A Always heed all WAR NINGS
� on page 232.
• After turning off the engine, wait a few
minu tes for the oil to return to the oil pan. VE
HICLE CARE
• Pull out dipstick (arrow) and wipe it clean
with a rag.
• Reinsert dipstick; push it all the way in.
• Pull dipstick out again and read the level:
a - Yo u must not add oil.
b- You can add oil. The oil level may go
into the a range, but riot above the a
range
c - You must add oil.
After filling in oil, make sure that the oil
level is somewhere within the b range.
• After checking the oil level, please make
sure that the dipstick is pushed back in all
the way.
