TIPS AND ADVICE
Under normal conditions, the rate of oil con-
sumption depends on the quality of the oil
as well as its viscosity, the rpm's (revolu-
tions per minute) at which the engine is
operated, the outside temperature, the road
conditions, as well as the amount of oil dilu-
tion by condensation water or fuel residue
and by the oxidation level of the oil. As en-
gines wear, oil consumption may increase
over time until replacement of worn engine
parts may become necessary.
Because of all of these variables, it is not
possible to specify a standard or "normal"
rate of oil consumption. For this reason, we
urge you to check the oil level in your engine
at regular intervals, preferably every time
you refuel, and always before going on a
long trip.
The oil pressure light is not an indicator of
low engine oil level. If the warning light does
not go out or flashes while driving (above
1500 engine rpm) a buzzer will sound. It indi-
cates that the oil pressure is too low. Stop
the engine immediately, check the engine
oil level, and add oil if necessary. If the en-
gine oil level is normal, but the light contin-
ues to flash, do not continue to operate the
vehicle. Engine damage may occur.
If you believe your engine uses excessive
amounts of oil, we recommend that you
consult your authorized Volkswagen dealer
so that the cause of your concern can be
properly diagnosed. Keep in mind that the
accurate measurement of oil consumption
requires great care and may take some
time. Your Volkswagen dealer has instruc-
tions on how to measure oil consumption
accurately.

in the engine compartment,
always read and heed all WARN-
INGS on page 40.
Notes
• The engine in your vehicle de-
pends on oil to lubricate and cool all
of its moving parts. Therefore the
engine oil should be checked regu-
larly and kept at the required level. (
• Make it a habit to have the engine
oil level checked every time you re-
fuel.
• Lack of sufficient engine oil may
cause severe engine damage.
• The oil pressure warning light is
not an oil level indicator.
