2010 PORSCHE CAYMAN oil temperature

Maintenance, Car Care
191
If your vehicle is used frequently in stop-and-go
traffic in cold weather, the engine will not always
be properly warmed up.
Condensation from products of combustion may
accumulate in the oil. In this case, it is advisable
to change the oil more frequently so that your en-
gine once again has 100% efficient engine oil. Engine oil performance class Engine oil is not only a lubricant, but also serves
to keep the engine clean, to neutralize the dirt
which penetrates into the engine through combus-
tion and to protect the engine against corrosion.
To perform these functions, the oil is provided with
additives which have been specially developed for
these functions.
The efficiency of an oil is expressed, for example,
by the API, ILSAC or ACEA classifications.
Viscosity Like all liquids, engine oil is viscous when cold,
and thin-bodied when warm. The viscosity of an oil
is expressed by its SAE class. For cold viscosity
(measured at temperatures below 32 °
F/0 °
C) the
SAE class is given as a number and the letter “W”
(as in winter), for hot viscosity (measured at
212 °
F/100 °
C) the SAE class is given only as a
number.
The viscosity of an oil is, therefore, always the
same if it has the same number of an SAE class.
Oils with two viscosities are called multigrade oils;
oils with only one viscosity are termed single-
grade oils.
Single-grade oils can not be used in your engine.
The viscosity of the engine oil for your Porsche
has to be chosen according to the ambient tem-
perature given in the engine oil recommendation
table.

Maintenance, Car Care
Refueling Fuel tank capacity is listed under “Capacities”.
Porsche does not recommend the use of fuel ad-
ditives.
Fuel is highly flammable and harmful to
health.
fPlease see the chapter “CAPACITIES” on
Page 271. 1.
Important: Stop the engine and switch off the
ignition.
2. Slowly unscrew the tank cap. Hang the tank cap's plastic strap on the hook
on the inside wall of the filler flap.
3. Insert fuel-hose nozzle fully into the filler neck
with the handle of the fuel-hose nozzle facing
down.
4. Do not add further fuel once the correctly op- erated automatic fuel-hose nozzle has
switched off.
Fuel could spray or could run over in warm
temperatures.
5. Replace the tank ca p immediately after
refueling and turn it until you hear it and feel it
engage.
If you lose the tank cap, you must replace it
only with an original part to reduce the
possibility of a fire in the event of a collision.
Caution!
Risk of damage. Decorative film may fade
if it comes into contact with fuel.
f Wipe off any emerging fuel immediately.
Fuel Recommendations Your Porsche is equipped with catalytic convert-
ers and must use UNLEADED FUEL ONLY .
Your engine is designed to provide optimum per-
formance and fuel economy using unleaded premi-
um fuel with an octane rating of 98 RON
(93 CLC or AKI) . Porsche therefore recom-
mends the use of these fuels in your vehicle.
Porsche also recognizes that these fuels may not
always be available. Be assured that your vehicle
will operate properly on unleaded premium fuels
with octane numbers of at least 95 RON
(90 CLC or AKI) , since the engine’s “Electronic
Oktane™ knock control” will adapt the ignition tim-
ing, if necessary.
It is important to observe the regular service inter-
vals, and particularly the oil change intervals,
specified in the “Maintenance” booklet.
The use of UNLEADED FUEL ONLY is critically
important to the life of the catalytic
converters. Deposits from leaded fuels will
ruin the converters and make it ineffective
as an emission control device.
Cars with catalytic converters have a smaller fuel
tank opening, and gas station pumps have smaller
nozzles. This will prevent accidental pumping of
leaded fuel into cars with catalytic converters.

Practical Tips, Emergency Service
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
f The engine compartment of any motor vehicle
is a potentially hazardou s area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution also applies to the entire vehicle.
f O n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
f Ensure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially cau-
tious of such devices such as hot water heat-
ers which ignite a flame intermittently.
f Before working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
f Be alert and cautious around engine at all
times while the engine is running.
If work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral position
or the PDK selector lever in position P or N. f
In particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, long hair, hand or fingers cannot get
caught in the engine-compartment blower, fan,
belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The engine-compartment blower is mounted in
the engine-compartment.
The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the en-
gine off, the ignition switched off, and exercise
extreme caution.
f Your Porsche is equipped with an electronic ig-
nition system. When the ig nition is on, high volt-
age is present in all wires connected with the
ignition system; therefore, exercise extreme
caution when working on any part of the engine
while the ignition is on or the engine is running.
f Always support your car with safety stands if it
is necessary to work under the car.
Jacks are not suitable for this kind of work.
f When working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine
cannot be started.
Remove the ignition key. f
Do not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
f Incomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your au-
thorized Porsche dealer.
Improper maintenance during the warranty pe-
riod may affect your Porsche warranty cover-
age.
f Supplies of fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to your health.
Keep these fluids out of children’s reach and
dispose of them in accordance with the appro-
priate regulations.
f Some countries require additional tools and
special spare parts to be carried.
Please make enquiries before driving abroad.
