open gas tank AUDI A6 2018 Owners Manual

Checking and Filling
-If you a re unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified a re not the respon­
sibility 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 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 manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades differ from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engin e
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TI ER Dete rgent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline , please go to the official website
(www .toptiergas .com) .
After an extended per iod of us ing inadequate
fuels, carbon deposit build-ups can rob your
en­
gine of peak performance.
(D Note
Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle Limited Warranty.

Emissions control
system
Cat alytic converter
The vehicle may only be driven w ith unleaded
gaso line , otherwise the catalytic converte r will be
dest royed .
Never dr ive until the tank is completely empty.
The irregular supply of fuel that results from that can cause engine misfires. Uncombusted fuel will
enter the exhaust system, which can cause over­
heating and damage to the catalytic converter .
&_ WARNING
The temperature of the exhaust system is
h igh, both when driving and a fter stopp ing
the engine.
-
- Never tou ch the exhaust tail pipes once they
have become hot. This cou ld resu lt in burns.
- Do not park your vehicle over flammable
materials s uch as grass or leaves because
the high temperature of the emissions con­
trol system could start a fire .
- Do not apply unde rbody protectant in the
exhaust system area, beca use this increases
the risk of fire.
