Cautions; Engine Oil - Porsche 928 ST1991 Owner's Manual

Engine oil

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 di-
lution and oxidation of the lubricant.
Because of these variables, no standard rate
of oil consumption can be established, but
drivers should expect an increased oil con-
sumption at high speeds and when the en-
gine is new.
• The engine in your vehicle depends on
oil to lubricate and cool all of its mov-
ing 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.
• Lack of sufficient engine oil may lead
to severe engine damage.
• The oil pressure warning light is not an
oil level indicator.
The oil level should be between the "max"
and "min" marks on the dipstick. If the oil
level drops below the "min" mark, a fault
message appears in the information sys-
tem display when the ignition is switched
on. Top up the engine oil.
Checking oil level
To get a true reading, the car should be on
level ground. After turning off the engine,
wait a few minutes for the oil to return to the
oil sump.
1. Pull out dipstick and wipe it dry with a
clean cloth or paper towel.
2. Reinsert dipstick; push it in all the way
down for an accurate reading.
3. Pull dipstick out again. The oil level is cor-
rect if it is between the "max" und "min"
marks on the dipstick.
4. If oil level is below "min" mark, or not
showing on dipstick, add oil immediately.
The difference between the two marks is
about 1.6 U.S. qt. or 1.5 Liter.
Should the engine oil level be too low, the
central warning light and the engine oil
level warning light will flash as soon as
the ignition is turned on (see "central
warning light system"). Do not start the
engine but add oil immediately or contact
your Porsche dealer.
See "Cautions"
Adding engine oil
Only add the amount of oil that is needed.
The correct oil grade and viscosity recom-
mendation is given under "Engine Oils".
1. Remove oil filler cap (arrow).
2. Top up with quality oil labeled "API Ser-
vice SF or SE".
3. Check oil level with the dipstick - upper
mark should not be exceeded.
4. Replace cap and tighten.
WARNING
The oil filler cap and dipstick must be sec-
ure to avoid oil spills and resulting fire
hazard. |
