Engine Oil - Porsche CARRERA GT-2004 Manual

If in an emergency pure water has been added, the
mix ratio must be corrected at an authorized
Porsche dealer.
Significant loss of coolant indicates leakage in the
cooling system.
The cause should immediately be remedied at an
authorized Porsche dealer.
Engine-compartment blowers,
radiator fans
The radiator and radiator fans are in the front of
the car and in the engine compartment.
The engine-compartment blowers are mounted in
the engine compartment.
Warning!
Risk of injury.
After the engine is switched off, the engine-
compartment and coolant temperatures are
monitored for approx. 20 minutes.
During this period, and depending on tem-
perature, the engine-compartment blowers
and radiator fans may continue to run or
start to run.
f Carry out work in these areas only with the en-
gine off, the ignition switched off, and exercise
extreme caution.

Engine Oil

Engine oil consumption
It is normal for your engine to consume oil.
The rate of oil consumption depends on the quality
and viscosity of oil, the speed at which the engine
is operated, the climate, road conditions as well
as the amount of dilution and oxidation of the
lubricant.
If the vehicle is used for repeated short trips, and
consumes a normal amount of oil, the engine oil
measurement may not show any drop in the oil
level at all, even after 600 miles (1,000 km) or
more. This is because the oil is gradually becom-
ing diluted with fuel or moisture, making it appear
that the oil level has not changed.
The diluting ingredients evaporate out when the
vehicle is driven at high speeds, as on an express-
way, making it then appear that oil is excessively
consumed after driving at high speeds.
If the conditions you drive your vehicle in are
dusty, humid, or hot, the frequency of the oil
change intervals should be increased.
If the vehicle is driven at a high rate of speed,
climatic conditions are warm, and the load is high,
the oil should be checked more frequently, as
driving conditions will determine the rate of oil
consumption.
– The engine in your vehicle depends on oil to
lubricate and cool all of its moving parts.
Therefore, the engine oil should be checked
regularly and kept at the required level.
– Make it a habit to have the engine oil level
checked with every fuel filling.
– The oil pressure warning light is not an oil level
indicator.
The oil pressure warning light indicates serious
engine damage may be occuring when lit, if en-
gine rpm is above idle speed.
