A
Warning!
Risk ofinjury.
After theengine isswitched off,theengine-
compartment andcoolant temperatures are
monitored forapprox. 20minutes.
During thisperiod, anddepending ontem-
perature, theengine-compartment blower
and radiator fansmaycontinue torun or

Engine oilconsumption

It is normal foryour engine toconsume oil.
The rate ofoil consumption dependsonthe quality
and viscosity ofoil, the speed atwhich theengine
is operated, theclimate, roadconditions aswell
as the amount ofdilution andoxidation ofthe
lubricant.
If the vehicle isused forrepeated shorttrips, and
consumes anormal amount ofoil, the engine oil
measurement maynotshow anydrop inthe oil
level atall, even after600miles (1000 km)or
more. Thisisbecause theoilisgradually becom-
ing diluted withfuelormoisture, makingitappear
that theoillevel hasnotchanged.
The diluting ingredients evaporateoutwhen the
vehicle isdriven athigh speeds, ason anexpress-
way, making itthen appear thatoilisexcessively
consumed afterdriving athigh speeds.
If the conditions youdrive yourvehicle inare
dusty, humid, orhot, thefrequency ofthe oil
change intervals shouldbegreater. If
the vehicle isdriven atahigh rateofspeed,
climatic conditions arewarm, andtheload ishigh,
the oilshould bechecked morefrequently, as
driving conditions willdetermine therate ofoil
consumption.
- The engine inyour vehicle depends onoilto
lubricate andcool allofits moving parts.
Therefore, theengine oilshould bechecked
regularly andkept atthe required level.
- Make ita habit tohave theengine oillevel
checked withevery fuelfilling.
- The oilpressure warninglightisnot anoillevel
indicator.
The oilpressure warninglightindicates serious
engine damage maybeoccuring whenlit,ifen-
gine rpmisabove idlespeed.

Preconditions forcorrect
oillevel

measurement withtheoildipstick

Vehicle mustbelevel.
- Engine mustberunning andatoperating
temperature (engine coolant temperature ofatleast
176T /

80°C).
- The engine mustidleforatleast 20seconds
(under 1,000rpm).
- The airconditioning mustbeoff.

Checking
the
oillevel
andtopping off
engine oil

1. Apply handbrake andputthe gearshift leverin
neutral.
2. Unscrew capAof the oilfiller opening.
Withdraw dipstickBand wipe itwith aclean,
lint-free cloth.
3. Push dipstick fullyhome, withdraw againand
read offthe oillevel.
Push dipstick inas far asthe stop.
The

oillevel
must inno case fallbelow the
minimum orexceed themaximum
oillevel

on the dipstick.

The difference betvv'eenthetwo marks isapproxi-
mately 1.0liter/l.l quarts.
4. Add engine oilquarter-liter atatime, ifneces-
sary.
5. Check oillevel withthedipstick again.
6. Carefully closecapofthe oilfiller opening.

Oilchange

The engine oilhas tobe changed atthe intervals
listed inyour
Maintenance Schedule.

'" Please observe thechapter "CAPACITIES" on
Page 185.
We recommend thatyouhave theengine oil
changed atyour Porsche dealer,whohasthere-
quired oilsand thenecessary fillingequipment.
If you suspect anoilleak inthe engine haveyour
dealer checkitout immediately.
All current engineoilsarecompatible witheach
other, i.e. when making anoilchange itis not nec-
essary toflush theengine ifyou wish touse adif-
ferent brandorgrade ofoil.
Since, however, eachbrand ofoil has aspecial
composition, youshould, ifpossible, usethe
same oilbrand ifit becomes necessary totop up
between oilchanges.
Porsche engineshavelongintervals betweenoil
changes. Youcanmake bestuseofthese longoil
change intervals byusing multigrade oilssince
these arelargely independent ofseasonal fluctua-
tions intemperature.

Maintenance, CarCare If
your vehicle isused frequently instop-and-go
traffic incold weather, theengine willnot always
be properly warmedup.
Condensation fromproducts ofcombustion may
accumulate inthe oil.Inthis case, itis advisable
to change theoilmore frequently sothat your en-
gine once again has100% efficient engineoil.

Engine oilperformance class

Engine oilisnot only alubricant, butalso serves
to keep theengine clean,toneutralize thedirt
which penetrates intotheengine through combus-
tion andtoprotect theengine against corrosion.
To perform thesefunctions, theoilisprovided
with additives whichhavebeen specially devel-
oped forthese functions.
The efficiency ofan oilisexpressed, forexample,
by the API, ILSAC orACEA classifications.
Viscosity

Like allliquids, engineoilisviscous whencold,
and thin-bodied whenwarm. Theviscosity ofan oil
is expressed byitsSAE class. Forcold viscosity
(measured attemperatures below32°F
jO°C)
the
SAE class isgiven asanumber andtheletter "W"
(as inwinter), forhot viscosity (measured at
212°FjlOO°C) theSAE class isgiven onlyasa
number.
The viscosity ofan oilis,therefore, alwaysthe
same ifithas thesame number ofan SAE class.
Oils with twoviscosities arecalled multigrade oils;
oils with onlyoneviscosity aretermed single-
grade oils.
Single-grade oilscan notbeused inyour engine.
The viscosity ofthe engine oilfor your Porsche
has tobe chosen according tothe ambient tem-
perature giveninthe engine oilrecommendation
table.

Exercise ExtremeCautionwhen
Working onyour Vehicle

A
Warning!
Ignoring thefollowing instructions may
cause serious personal injury.

I>
The engine compartment ofany motor vehicle
is apotentially hazardous area.Ifyou arenot

ventilated area.

I>
Ensure thatthere arenoopen flames inthe
area ofyour vehicle atany time when fuel
fumes mightbepresent. Beespecially cau-
tious ofsuch devices suchashot water heat-
ers which igniteaflame intermittently.

I>
Before working onany part inthe engine com-
partment, turntheengine offand letitcool
down sufficiently. Hotengine compartment
components canburn skinoncontact.

I>
Bealert andcautious aroundengineatall
times whiletheengine isrunning.

PracticalTips,Emergency Service
I>

Inparticular, bevery careful toensure that
items ofclothing (ties,shirt, sleeves etc.),jew-
elry, long hair,hand orfingers cannotget
caught inthe engine-compartment blower,fan,
belts orother moving parts.
The radiator andradiator fansareinthe front
of the car.
The fans canstart orcontinue runningasa
function oftemperature, evenwiththeengine
switched off.
Carry outwork inthese areasonlywith theen-
gine off,theignition switched off,and exercise
extreme caution.

I>
Your Porsche isequipped withanelectronic ig-
nition system. Whentheignition ison, high volt-
age ispresent inall wires connected withthe
ignition system; therefore, exerciseextreme
caution whenworking onany part ofthe engine
while theignition ison orthe engine isrunning.

I>
Always support yourcarwith safety stands ifit
is necessary towork under thecar.

I>
When working underthecarwithout safety
stands butwith thewheels onthe ground,
make surethecar ison level ground, the
wheels areblocked, andthat theengine
cannot bestarted.
Remove theignition key.
I>

Donot smoke orallow anopen flame around
the battery orfuel.
Keep afire extinguisher inclose reach.

I>
Incomplete orimproper servicingmaycause
problems inthe operation ofthe car. Ifin doubt
about anyservicing, haveitdone byyour au-
thorized Porschedealer.
Improper maintenance duringthewarranty pe-
riod may affect yourPorsche warranty cover·
age.
