Engine oil
Engine oil specifications
The engin e oil used in your Audi needs the right kind of oil.
Th e e ng ine in your Aud i is a sophis ticated powerplant that was bui lt
to exacting spec ificat ions. This engine needs the r ight kind of engine
oil t hat meets spec ifi cat ions regarding qu ality a nd viscosity so t hat it
can run smooth ly and re liably. Choosing the right o il and changing oil
with in the time and mileage intervals pr in ted in your veh icle 's
Warranty & Maintena nce book let matters a lot more today than it did
years ago . Audi has developed a specia l quality standard for engine oil
that w ill help assure that your veh icle's engine will get t he lubr ication
it needs fo r prope r operation.
M ode rn engine lubr ication has taken a quan tum leap in the last few
years. Many synthet ic oils available today provide better engine lubri­
c at ion th at c an outlast tradit ional petro le u m-based o ils, making
them a smart choice for use throughout the life of your Aud i.
Whethe r you use synthetic or petroleum -based engine oi l, the o il th at
yo u use must confo rm to A ud i's o il quality sta ndard VW 502 00 (vehi­
cles with gasoline engine) or VW 507 00 (vehicles with d iese l eng ine)
to he lp keep you r vehi cle's e ngine run ning smoothly and help p revent
the format ion of harmfu l deposits, somet imes called "sludge," that
over time can lea d to expens ive rep airs.
At the time of pr int ing, engine o ils avai lab le in the U .S . and Ca nada
t ha t meet the exacting spec ificat ions o f Audi o il standar d VW 502 00
(vehicles w it h gasoline eng ine) or VW 507 00 (vehicles w ith d iese l
eng ine) are synthetic engine oils . This does not mean, howeve r, that
Safety first
every synthetic engine oil w ill meet Audi o il standard VW 502 00
(vehicles wit h gasoline eng ine) or VW 507 00 (vehicles wi th di esel
engi ne). So a lways be sure that you use an approved oil.
T o help preve nt the format io n of harmfu l deposits use only oi l with
t he follow ing s peci fica tions p rin ted on the oil con tainer:
• Audi oil standard VW 502 00 (gasoline engine)
• Audi oil standard VW 507 00 (diesel engine )
Oil container labe ls may carry the specification s ingly or in comb ina ­
t ion wi th ot he r designa tions a nd o il quali ty stand ards.
Viscosity
Engine oils are g raded acco rding to the ir viscosity. The proper
vis cos ity gra de oi l for your engi ne depends o n clim actic or se ason al
conditions where you drive . You can use oil with a v iscosity grade of
SA E S W40 across a ll tempe rature ranges fo r norma l driv ing con di­
tions .
However, if en gine oi l v iscosity grade SAE SW 40 is not avai lab le, you
c an a lso use viscos ity grade SA E SW-30 or SA E OW -40 as long as it
meets Audi o il quality standa rd VW 502 00 (vehicles w ith gasoline
engi ne) or VW 5 07 00 (vehicles w it h diese l engine) speci fications .
Beca use engine o il that meets the Aud i oil standard may not be avail­
able everywhere when yo u nee d it, we strongly recommend t hat you
always carry w it h you an extra quart (liter) of o il that e xpress ly
conforms to the VW 502 00 (vehicles w ith gasoli ne engine) or VW
507 00 (vehicles w ith diesel engin e) specification, in case you have to
to p off t he oil while on the roa d.
Applies to vehicles with gasoline engine only: Only if th e leve l of the
oil is at or below the minimum mark on the o il dipstick -and no oil
t ha t expressly conforms to Aud i oil st anda rd VW 5 02 00 specifica ­

Aud i Customer Relations at 1 (800) 822 -2834 or vis it our web site at
www.aud iusa .com or www .aud icanada.ca . He re yo u w ill also find a
cu rrent list of oils (manufactu rers, brand names e tc.) that co nform to
Audi oil standard VW 502 00 (vehicles with gaso line e ngine) or VW
507 00 (vehicles w it h die sel eng ine).
Changing the engine oil
The eng ine oil and oil fi lter mus t be changed according to the mileage
(kilome ters) and t ime intervals specified i n your vehicle 's Warranty &
Ma intenance booklet . Do not exceed these interva ls - harmful
deposi ts from o ld engi ne oil can reduce engine pe rfo rmance and ca n
lead to expensive engine repa irs.
C hangi ng the oil at the recommende d interva ls is so very imp ortant
because the lubricating properties of o il decrease gradually during
normal ve hicl e use. If yo u ar e not sure w hen you have yo ur oil
changed, ask your author ized Audi Service Adv isor .
Under some circumstances the eng ine o il should even be changed
more fr eq uent ly. Chang e oil mor e of ten if you d rive mostly short
distances, operate the veh icle in d usty areas or mostly under stop­
and -go t raff ic condi tion s, or when you use yo ur vehicle where tempe r­
atures stay be low free zing po int for long periods.
De tergen t ad dit ives in the o il wi ll m ake fres h oil look dark a fter the
eng ine has bee n ru nning for a short t ime . This is normal and is not a
reason to ch ang e the oil mo re of ten t han re commended.
Damage or malfunctions due to lack of maintenance
It is essentia l that you change your o il at the recommended intervals
using only en gine oil th at com plies wi th A udi o il st and ard VW 502 0 0
(vehicles w ith gasoline eng ine) o r VW 507 00 (vehicles with d iesel
eng ine) . Your Limited New Vehicle Wa rranty does not cover damage
or ma lfunct ions due to fa ilure to follow recomm ended maintena nce
and use requirements as set forth in t he Au di Owner's Man ua l and
W arranty
& M aintenance boo klet. Y ou r deale r will have to deny
wa rranty coverage unless yo u present to the dealer proof i n th e form
of Se rvice o r Rep air O rders tha t al l sche dul ed main tena nce was
performed in a time ly ma nner. •
Engine oil consumption
To provide effective lubr ication a nd cooling for interna l eng ine parts,
a ll in ter na l c omb ustion e ngines use some oil. Oil cons umption v aries
from engine to engine and may change over the life of the eng ine .
E ngines te nd to use m ore oi l dur ing the b re a k-i n period t han t hey do
after ward, when oil consumption has stab ilized. Depending on t he
way the vehicle is driven and the operatin g cond itions, oi l cons ump ­
tion ca n be up to 1 qua rt pe r 1,200 m iles
(I liter per 2 ,000 km).
Consumption may be higher withi n th e first 3,0 00 miles (5,00 0 km).
Under nor mal co ndi tions, the rate o f oi l consu mptio n depe nds o n oil
quality as well as viscosity, engine speed ( rpm), o utside tempe rature,
roa d condi tion s, the amou nt of o il d ilution caused by co nde nsed
water or fu el residue, and oxidation of the oil. O il cons umption may
increase wi th en gine we ar ove r time, un til repl aceme nt of worn
eng ine pa rts may become necessa ry.
Because of all these var ia bles, there is no standa rd o r "norma l" rate
of oil consumption .
We urge you to check the engine oil level at
regular intervals, preferably every time you fill the fuel tank, and
always before a long trip .
The oil pressure warning light
~ is not an indicator of low eng ine
oil level. If the warning light does not go out after starting, or
flashes while driving (above 1500 rpm), a buzzer will sound . It
indicates that the oil pressure is too low. Stop the engine immedi- _.,,

_____________________________________________ C_h _ e_ c_ k_in --= g'-- a_n _d_ f_i _ll _i_n -=g ::;__ ____..
ately, check the engine oil level and add oil if necess ary. If the
engine oil level i s normal, but the light continues to flash , do not
keep driving or l et the engine idle , as damage may occur .
If you believe your engine uses too much oil, we recommend that you
cons ult your au thor ized Audi dealer so that the cause of yo ur conce rn
can be properly diagnosed. Keep in m ind that accurate measurement
of oil consump tion req uires gre at care a nd may ta ke some time. You r
Audi dealer has instructions for how to measure o il consumption
a ccu rately.
