2015 AUDI Q3 warning

176 Fuel suppl y and fillin g your fu el tank
Many gaso line grades are blended to perform
especially we ll 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
spec ified criter ia in this chapter .
- If you are unable to determine whether
or not a particular fuel blend meets the
spec ificat ions, ask your service station o r
i ts fuel supplier .
- Do not use fuel for wh ich the contents
cannot be identified .
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the respons ibility of Audi and are not
covered under the New Ve hicle or the
Emission Control System Warranties.
- If you experience a loss of fue l economy
or driveabil ity and performance prob­
l ems due to the use o f 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 .
A lthough gasoline grades diffe r from one
manufac turer to another, they have certa in
things in common. All gasoline grades contain
substances that can cause depos its to collect
on vital engine parts, such as fuel injectors
and intake valves . Although most gasoline
b rands include additives to keep eng ine and
fuel systems clean , they are not eq ua lly 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 o f using inadeq uate
fuels, built-up carbon deposits can rob your engine of peak performance.
(D Note
- Damage or malfunction due to poor fuel
quality is not covered by the Audi New
Vehicle Limited Warranty .
- Do not add afte rmarket fuel additive
produc ts to your f uel tank .

Engine oil
Engine oil specifications
The engine in your Audi needs the right kind
of oil.
The eng ine in your Audi is a sophisticated
power p lant that was bu ilt to exacting specifi­
cations. This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can run
smooth ly and reliab ly. Choosing the rig ht o il
and changi ng oil within the t ime and mileage
in tervals printed in you r vehicle's Warranty
&
Maintenance booklet matters a lot more to ­
day than it did years ago . Audi has developed
a specia l quality standard for engine oil that
will help assure that your vehicle's engine w ill

temperatures stay below freezing point for l ong periods.
Detergent add itives in the o il w il l make fresh
oil look dark after the eng ine has been run ­
ning fo r a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am ag e or m alfun ction s due to lack of
ma intenanc e
It is essential that you change your oil at the

Engine oil consumption
The engine in your vehicle dep ends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to provide effective lubrication and
cool ing of i nternal engine components, a ll in­
ternal comb ustion eng ines consume a cert ain
amo unt of o il. Oil cons umption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in per iod (see
c::;, page 161) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized.
Under norma l conditions, the rate of oil con ­
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the amb ient
temperature and road condit ions. Furthe r fac­
tors ar e the amount of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is s ubje ct to
Checkin g and fillin g 183
wear as m ileage builds up, the oil consump ­
tion may increase over time until replacement
of worn components may become necessary.
Wi th a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es ­
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
E\I in the instrument cl uster lights up, you
sho uld check the oil leve l as soon as possib le
c::;, page 184. Top off the oil at your earliest
convenience

WARNINGS
c::;, .&. in Working in th e engine

(D Note
D riving w ith an insufficient o il level is like­
ly to cause sever e damage to the engine .
(D Tips
- The oil pressure warning display. is
not an indicator of the oil le vel. Do not
re ly on it. In stead, check the oil level in
your engine at regular intervals, pref­ erably ea ch time you refuel, and alway s
before going on a long trip .
-If you have the impression you r engi ne

recommend that you consu lt an author ­
ized Aud i dea ler to have the cause of
your concern properly d iagnosed. Keep in

Before you check anything in the engine com­
par tment,
a lways rea d and he ed all WARN ­
INGS ~&. in Working in the engine compart­
ment on page 179.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance book let. This is very important
because the lubricating properties of oil di­
minish gradua lly during normal vehicle use.
Under some circumstances the engine oi l
should be changed more frequently. Change
oil more often if you drive most ly short dis­
tances, operate the vehicle in dusty areas or under predominantly stop-and-go traff ic con­
d itions, or have your veh icle where tempera­
tures remain below freezing for extended pe ­
riods.
Detergent additives in the o il w ill make fresh
oil look dark after the engine has been run­ n ing for a short time. This is normal and is not
a reason to change the oil more often than recommended.
Because of the problem of proper disposa l,
along w ith the special tools and necessary ex ­
pertise required, we strongly recommend that
you have you r oi l changed by an authorized
