Checking and Filling

Checking and Filling
Fuel
Types of gasoline
The correct gasoline grade is stated on the inside
of the fuel filler door.
The vehicle is equipped with a catalytic converter
and must only be driven with unleaded gasoline.
Audi recommends using TOP TIER Detergent Gas-
oline. For additional information on TOP TIER De-
tergent Gasoline, visit www.toptiergas.com.
The individual gasoline grades are differentiated
by octane ratings. This value is given with (R
+M)/2 equating to AKI or in RON.
The headings below match the sticker in the fuel
filler door (examples):
UNLEADED FUEL ONLY MIN. (R+M)/2 87
Regular / MIN. RON 91 Regular
Use regular gasoline with minimum 87 AKI /
91 RON > ©.
Audi recommends using premium gasoline with
minimum 91 AKI / 95 RON to achieve the rated
horsepower and torque.
UNLEADED FUEL ONLY PREMIUM MIN. (R
+M)/2 91 / SUPER MIN. RON 95
Using premium gasoline with minimum 91 AKI /
95 RON is recommended.
If premium gasoline is not available, you can also
use regular gasoline 87 AKI / 91 RON. However
this does reduce the engine power slightly.
UNLEADED FUEL ONLY PREMIUM MIN. (R
+M)/2 93 / SUPER PLUS MIN. RON 98
Using premium plus gasoline with at least 93
AKI / 98 RON is recommended.
If no premium plus gasoline is available, you can
also use premium gasoline with 91 AKI /95 RON.
However this does reduce the engine power
slightly.
CG) Note
— Filling the tank just one time with leaded
fuel or other metallic additives will cause
permanent deterioration to the catalytic
converter function.
— When gasoline with an octane rating that is
too low is used, high speeds or heavy engine
load can lead to engine damage.
@ Tips
The vehicle may be filled with fuel that has a
higher octane rating than what is required by
the engine.
Gasoline mixture
Gasoline with alcohol or MTBE (Methyl-Tert-
Butyl-Ether)
You can use unleaded gasoline mixed with alco-
hol or MTBE (generally labeled as oxygenated
compounds) as long as the fuel meets the follow-
ing conditions:
Gasoline with methanol content (methyl alco-
hol or methanol)
— Anti-Knock Index is at least 87 AKI
—No more than 3% methanol
— More than 2% solvent
Gasoline with ethanol content (ethyl alcohol or
ethanol)
— Anti-Knock Index is at least 87 AKI
—No more than 15% ethanol
Gasoline with MTBE content
— Anti-Knock Index is at least 87 AKI
—No more than 15% MTBE
Gasoline adapted to the season
Many gasoline fuels are adapted to the seasons.
When the season changes, refueling at high-traf-
fic gas stations is recommended. It is more likely
that the gasoline will be suitable for the season
there.
@) Note
— Gasoline with methanol content that does
not meet the specified conditions may cause >

Checking and Filling

Engine oil
If the engine oil level is too low
If you need to add engine oil, use an oil that is
listed on the sticker. The sticker is located at the
front of the engine compartment > page 223,
fig. 159. When using the engine oil listed on the
sticker, you can adjust the oil level as often as
needed.
If engine oil that meets the recommended speci-
fication is not available, in an emergency you
may add a maximum of 1 quart (1 liter) of
ACEA C3 or API SN engine oil one time until the
next oil change.
For more information on the correct engine oil
for your vehicle, contact an authorized Audi deal-
er or authorized Audi Service Facility. Have the oil
changed by an authorized Audi dealer or author-
ized Service Facility.
G) Tips
Audi recommends using engine oils provided
by Audi Genuine Parts.

ZA\ WARNING
— When adding oil, do not let oil drip onto hot
engine components. This increases the risk
of a fire.
— You must close the cap on the oil filler open-
ing correctly so that oil does not leak out on-
to 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.
—
Engine oil is poisonous and must be kept out
of reach of children.
— Store the engine oil securely in the original
container.

@) Note
— The New Vehicle Limited Warranty does not
cover damage or malfunctions if the recom-
mended intended use of the vehicle and
maintenance measures listed in the Audi
Owner's Manual and the Warranty & Main-
tenance Booklet were not followed.
— Only use high-grade engine oil that explicit-
ly meets the Audi oil quality standard for
your vehicle. Using another oil may cause
severe vehicle damage.
— Do not mix any additives with the engine oil.
Additives may cause engine damage that is
not covered by your New Vehicle Limited
Warranty.
226
@) For the sake of the environment
— Oil should never enter the sewer system or
come into contact with the ground.
— Follow the legal regulations in the country
where you are located when disposing of
empty oil containers.
Changing engine oil
Audi recommends having the oil changed at an
authorized Audi dealer or authorized Audi Serv-
ice Facility.
Observe the safety precautions > page 221, Gen-
eral information.
The engine oil must be changed at the intervals
specified in the Warranty & Maintenance Book-
let. This is very important because the lubrication
function of the oil gradually declines during regu-
lar vehicle operation.
The engine oil should be changed more frequent-
ly under certain circumstances. Have the oil
changed more frequently if you often drive short
distances, your vehicle is predominantly in stop-
and-go traffic situations, is in very dusty environ-
ments, or is operated for long periods of time in
temperatures below zero.
Cleansing additives in the oil make fresh oil ap-
pear darker after the engine has run briefly. This
is normal and no reason to change the engine oil
more frequently than recommended.
Because correctly disposing of engine oil is diffi-
cult and special tools and technical knowledge
are needed for an oil change, Audi recommends
having your engine oil changed by an authorized
Audi dealer or authorized Audi Service Facility.
If you change the engine oil yourself, please note
the following important information:

Z\ WARNING
If you change the engine oil on the vehicle
yourself, the following precautions must be
followed:
— Wear protective eyewear.
— Due to the risk of scalding, allow the engine

to cool down sufficiently. >
