Engine Oil Level - Porsche 928 GTS 1994 Owner's Manual

Engine oil level

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 en-
gine is operated, the climate, road conditions as
well as the amount of dilution 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 consumption at
high speeds and when the engine is new.
* 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 re-
quired 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 or if the
oil level sending unit is not working, a fault
message appears in the information system
display when the ignition is switched on.
Top up the engine oil or replace oil level
sending unit. See "Cautions".
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 correct
if it is between the "max" und "min" marks on
the dipstick.
4. If oil level is below "min" mark, or not show-
ing on dipstick, add oil immediately.
The difference between the two marks is
about 1.6 U.S. qt. or 1.5 Liter.
Adding engine oil
Only add the amount of oil that is needed. The
correct oil grade and viscosity recommendation
is given under "Engine Oils".
1. Remove oil filler cap (arrow).
2. Top up with engine oil.
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 secure
to avoid oil spills and resulting fire hazard.
