is drained when the engine is cold as the oil will be
thick and w

not drain thoroughly.
The crankcase refill capacity is 5 quarts except when the oil filter
element is changed. The refill capacity with a filter element change
is 6 quarts.
'
FIRST 1,000 MILES-The oil placed in the crankcase at the factory
is a high quality
"MS"
type, lOW oil with special break-in additives
and should be left in the engine for the first 1,000 miles. At the end
of the first 1,000 miles, the crankcase should be drained and refilled
to the proper level with an oil suitable for your individual climatic
and driving conditions as recommended in the above
.
chart. Should
it be necessary to add or change engine oil during the first 1,000
miles, an oil not heavier than lOW should be used.
Average Driving-For average driving conditions, an oil change is
recommended every 3,000 to 4,000
miles.
This applies to all owners
with the exception of those driving under the conditions described
in the following
paragraphs.
Driving in Dust-When the car is generally operated in dusty
territory, consideration should be given to more frequent oil changes.
Short Drives in Cold Weather-Short drives in cold weather
(freezing temperatures or lower) sucp as city driving do not permit
the engine to warm up thoroughly, and water may accumulate in the
crankcase from condensation of
moisture.
Under these conditions it
may be advisable to change oil at monthly intervals.
High Mileage Driving - For the exceptional
person who
is
operating his car 500 to 1,000 miles
per week consideration may be given to greater
mileage between oil changes. Oils have a tendency
i
to 'thicken on continuous high-speed
driving.
This
~
should be kept in mind when preparing cars for cold
g
weather driving.

o
ADDING OIL BETWEEN CHANGES - Since
Pontiac employs a full pressure lubrication
system,
it is not necessary to keep oil level up to the
"
FULL"
mark on the dipstick. It is only necessary to keep oil
level above the "ADD
OIL"
ma
rk. It takes two
quarts to bring the oil level from
"
ADD
OIL"
to
"FULL"
mark. E ach time the gas tank is filled, the
oil level should be checked. However, it is good
economy to let the oil level approach the "ADD
OIL"
mark before having your oil changed.
CAUTION: Do not overfill.
