Oil

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.

Octane ratings

The CLC orAKI octane ratingisusually lowerthan
the RON rating:
For example: 95RON equals 90CLC orAKI
Unleaded
fuelsmaynotbeavailable outsidethe
continental U.S.andCanada. Therefore, werec-
ommend youdonot take your cartoareas or
countries whereunleaded fuelmay notbeavail-
able.
Octane ratingindicates afuel's ability toresist det-
onation. Therefore, buyingthecorrect octanegas
is important toprevent engine"damage".
The RON octane ratingisbased onthe research
method. TheCLC (U.S. CostofLiving Council oc-
tane rating) orAKI (antiknock index)octane rating
usually displayed onU.S. fuelpumps iscalculated
as research octanenumber plusmotor octane
number, dividedby2,that iswritten as:
Fuels
containing MMT

Some NorthAmerican fuelscontain anoctane en-
hancing additive calledmethylcyclopentadienyl
manganese tricarbonyl(MMT).

If
such fuels areused, youremission controlsys-
tem performance maybenegatively affected.
The check engine warning lightonyour instrument
panel mayturnon.

If
this occurs, Porsche recommends youstop us-
ing fuels containing MMT.

ers inyour vehicle.

Fuels
containing alcoholandether

Some areasofthe U.S. require oxygenated fuels
during certain portions ofthe year. Oxygenated fu-
els are fuels which contain alcohols (suchasmeth-
anol orethanol) orether (such asMTBE).
Under normal conditions, theamount ofthese
compounds inthe fuel willnot affect driveability.
You may useoxygenated fuelsinyour Porsche,
provided theoctane requirements foryour vehicle
