Diesel Fuel - Audi A7 Sportback 2014 Owner's Manual

- Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
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.

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
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.

problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not

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 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 219
fuel systems clean, they are not equally effec-
tive.
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.

Diesel fuel
Applies to veh icles: with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) sul-
fur content 15 ppm or less.
The ULSD (Ultra Low Sulfur Diesel) meets the
ASTM-D-975 (grade 2).
Diesel fuel with a higher concentration than
ULSD-Diesel No. 2 ASTM 0975 and Bio-die-
sel with a higher concentration than 5 % like
B11, B20 or B100 are strictly prohibited.
Service station fuel pumps are labeled with
the correct fuel information for easy recogni-
tion by the user. If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
Service stations offering Diesel fuel are gener-
ally located on truck routes or major high-
ways. Directories of Diesel fuel stations are
usually available at Diesel fuel stations.
Some states in the USA require permits to
purchase Diesel fuel. Check with your State
Motor Vehicle Department.
Diesel fuel may not be available outside the
USA and Canada. Be sure to check before trav-
eling to other countries.
