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 built to exacting specifi­
cations . This engine needs the r ight kind of
engine o il that meets spec ificat ions regarding
qua lity and viscos ity so that it can run
smoothly and reliably . Choos ing the righ t oi l
and changing oil within the time and mileage
interva ls printed in your vehicle 's Warranty
&
Maintenance book let matters a lot more to­
day than it did years ago. Audi has developed
a special quality standard for engine oil that
will help assure that your veh icle's eng ine will
get the lubrication it needs for proper opera­
tion.
Modern engine 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 trad itional petrole -u
m -based oils, making them a smart choice
for use throughout the life of your Audi.
Whether you use synthet ic o r petro le um­
based eng ine oil, the oi l that you use m ust
conform to Audi's oi l quality standard
VW 502 00 to help keep your vehicle's engine runn ing smooth ly and help prevent the for­
mation of harmfu l deposits, sometimes called
"sludge," that over time can lead to expensive
repairs.
At the time of printing, engine oils ava ilable in
the U.S. and Canada that meet the exacting
specifications of Audi oil standard VW 502 00
are synthet ic eng ine oils . Th is does not mean,
howeve r, that every synthetic engine oil will
meet Audi o il standard VW 502 00 . So always
be su re that you use an approved oil.
To help prevent the formation of harmfu l de ­
pos its use only o il w ith the following specifi­
cations pr inted on the o il conta iner:
Audi oil standard VW 502 00
Oil container labels may carry the specifica­
tion sing ly or in combination with other desig ­
nations and oil quality standards.
V is cos ity
Engine o ils are graded a ccord ing to their vis­
cosity . The proper vis cos ity grade oil fo r yo ur
engine depends on climactic or seasona l con­
ditions where you drive. You can use oil with a
viscosity grade of SAE 5W40 across a ll tem­
perature ranges for norma l driving conditions.
However, if engine oil v iscosity g rade SA E
SW40 is not available , you can also use viscos ­
ity grade SAE SW-30 or SAE OW-40 as long as
it meets Audi oil qua lity standard VW 502 00
specifications.
Beca use engine oi l that meets the Audi oil
standard may not be availab le everywhere
when you need it, we strong ly recommend
that you a lways carry with you an extra quart
( li ter) of oil that express ly conforms to the
VW 502 00 spec ificat ion, in case you have to
top off the o il while o n the road . ..,_
