Fig. 1, is located on the left side of the
engine. It is divided off at the lower end
into two divisions — Oil Level Range and
Low.
For normal operation the oil level is
satisfactory when it is within the Oil Level
Range. For high speed operation the level
should be maintained at the full mark, that
is the top line on the Oil Level Range.
To make an accurate check of the oil
level it is best to wait a minute or two after
the engine has been shut off to permit the
oil on the engine parts to drain back into the
reservoir.
Two and one-half quarts of oil are required
to restore the level from low to full in both six and eight cylinder engines. If the level
is low, and the speedometer reading indicates that the oil change period is near at
hand, it is more economical to have the oil changed.
WHEN TO CHANGE ENGINE OIL
During the first 500 miles of driving it is satisfactory to use the oil which was
placed in the engine at the factory.
Thereafter at intervals of 2,000 miles the oil reservoir should be drained and
refilled with the proper grade of oil. If the car is operated constantly in dusty areas or
for short distances at slow speeds in the winter, which permits foreign matter to
accumulate in the oil and contaminate it, the oil should be changed more frequently.
The actual change period, however, depends largely on the individual circumstances.
To drain the oil remove the plug at the rear of the oil reservoir. Always drain the
oil when it is warm as it will then flow more freely.
It is good practice to remove the oil reservoir at least twice a year, preferably in
the fall and spring, to permit cleaning the screens and removing all traces of sludge
which may have accumulated in the lower pan.
Caution: When flushing oils or compounds are used in the engine, it is important
to remove the oil reservoir and thoroughly clean it out before installing the new oil.
THE PROPER ENGINE OIL TO USE
There are two important factors to consider when buying engine oil. The first is
the selection of a well-known, dependable brand. There are many good, well-bodied,
long-lived oils on the market and your selection should be based on the reputation of
the refiner or marketer. He is responsible for the quality of his product and his
reputation is the car owner's best indication of quality.
