2013 AUDI S8 mileage

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
11-Try and keep well below your car's maxi-
mum speed.
Accelerating gently reduces fuel consump­ tion, engine wear, and does not disturb the
environment.
F ue l consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
d itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
11-Shut the engine off when you are not driv­
ing the vehicle.
"" Do not warm up the veh icle by letting the
engine run at idle .
The idling phase is automat ically reduced for
vehicles w ith the Start/Stop system . It is effi­
cient to switch
off the engine in vehicles with­
out the Start-Stop-System when stopped at ra il road crossings and long red lights. Turning
the eng ine
off for just 30 -40 seconds saves
mo re fuel than is burned by s tarting the en­
gine again.
It takes a long time fo r the engine to wa rm up
fu lly when it is running at idle. Howeve r, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at h igh rpms while the engine is
still warming up.
CD Note
Do not leave engine idling unattended af­
ter starting. If warning lights shou ld come
on to indicate improper operation, they

would go unheeded. Extended idling a lso
produces heat, which could result in over­
heating or other damage to the veh icle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
11-Have your vehicle serviced at reg ular inter-
vals .
By having your ve hicle reg ularly se rviced by an
Audi dealer he lps to ensure that it runs prop­
erly and economically . The condition of your
vehicle not only affects its safety and ability to
ho ld its va lue, it also affects
fuel co nsump ­
tion .
Chec k your oil e ach t ime you fill y our t ank.
T he amou nt of o il used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reac h its lowest value after a certa in
mileage has bee n driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also applies to fuel consumption and en­ gine output .
CD Note
-Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Ma in­
tenance book let . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impai r the function of the
em ission cont ro l system and cou ld lead
t o damage.
- Do not alter or remove any component of
t he Emission Control System unless ap­
proved by the manufacture r.
- Do not alter or remove any devi ce, such
as heat shie lds, switches, ign ition w ires,
valves, which are designed to protect
your vehicle's Emission Control System

Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
-
The engine in your Audi is a sophisticated
powerp lant that was bu ilt to exacting specifi­
cations. This engine needs the r ight kind of
engine o il that meets specificat ions rega rding
qua lity and viscos ity so that it can run
smoothly and reliably . Choos ing the righ t oi l

inte rva ls printed in your veh icle's Warranty
&
M aintenance book let matters a lot more to­
day than it d id years ago. A udi has developed
a special quality standard for engine oil that
will he lp assure that your veh icle's eng ine will
get the lubrication it needs for prope r opera­
tion .
M odern eng ine lubrication has taken a quan­
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu­
brication that can outlast traditional pet role -

um -based oils, ma king them a smart cho ice
for use throughout the life of your Audi.
Whether you use sy nthetic o r pe trole um­
based eng ine oil, the oil tha t you use m ust
confo rm to Aud i's oi l quality standard
VW 502 00 to help keep your vehicle's engine runn ing smooth ly and he lp prevent the for­
mation of harmful deposits, sometimes called
"sludge," that over time can lead to expensive
repairs .
At the time of printing, engine oils ava ilab le in
the U.S. and Canada that meet the exact ing
specifications of Audi oi l standard VW 502 00
are synthet ic eng ine o ils . Th is does not mean,
howeve r, that every sy nthetic engi ne oil will
meet A udi o il standard VW 502 00 . So always
be s ure that yo u use an approved oil.
To he lp prevent the formation of harmfu l de­
pos its use on ly o il wi th the following specifi­
cat ions pr inted on th e oil conta iner:

Oil container labe ls may car ry the specifica­
tion sing ly or in combination with othe r desig ­
nations and oil quality standards.
Viscosity
E ngine o ils are graded a ccord ing to the ir vis­
cosi ty . T he p roper viscos ity grade oil fo r yo ur
engine depends on climactic o r seasona l con­
ditions where yo u drive. You can use oi l wit h a
viscosity grade of SAE 5W40 across all tem­
perature ranges for norma l driv ing cond itions.
However, if engine oil viscosity g rade SA E
5W40 is not available, you can also use viscos ­
ity grade SAE 5W -30 or SAE OW -40 as long as
it meets Audi oil q ua lity standard VW 502 00
specifications.
Because eng ine o il tha t meets the Audi oi l
standard may not be availab le everywhere
when you need it, we strong ly recommend
that you a lways carry wit h you an extra quart
( li ter) of oil that express ly conforms to the
VW 502 00 spec if icat ion, in case you have to
top off the o il while o n the road . .,..
