ubrication
In order that your LaSalle car may deliver throughout its
life, the performance built into it, we urge you to protect your
investment by conscientious observance of all of the items
recommended in this chapter.
NOTE: These lubrication items are given for
your guidance only, and not to encourage you or
your chauffeur to perform the work. Lubrication
is best performed with the efficient, specialized
equipment used in up-to-date service stations,
and there should be no occasion for resorting to
the slow, untidy, ineffective methods of former
years.
Authorized Lubrication
Lubrication operations can be performed most satisfactorily
by Authorized Cadillac-LaSalle service stations.
In addition to having the specialized equipment previously
referred to, they also have the correct lubricants, complete
instructions, and experience on LaSalle cars.
When a lubrication
operation is performed at
an Authorized Service
Station, the number of
the next lubrication and
the mileage at which it
is due will be posted on
the crest shaped plate on
the left front door pillar.
When this mileage appears
on the speedometer,

the car can be taken to any Authorized Service Station
and, by asking for "schedule lubrication," the car will
receive the exact lubrication required.
Authorized lubrication service can be purchased at a special
rate by means of the Lubrication Agreement. Ask your dealer
about this money-saving plan.
Engine Oil Recommendations
The proper selection of a crankcase oil will add much to the
performance, reliability, economy and long life of your engine.
During the first 1000 miles use the oil that was in the
crankcase when the car was delivered. When it is necessary
to add oil during this period, use nothing heavier than 10-W
oil in winter or 20-W in summer. Change the oil at the end
of 1000 miles.
NOTE: "Break-in" oils or compounds are
entirely unnecessary. They should not be used
under any circumstances unless the supplier can
furnish satisfactory proof that the compound
contains no harmful ingredients.
After the first 1000 miles the crankcase oil should be
selected to give the best performance under your individual
climatic and driving conditions.
During cold weather an oil should be used that will
permit easy starting at the lowest atmospheric temperature
that is likely to be encountered.
The same considerations that guide the car owner in
determining the strength of the anti-freeze solution for protection
throughout the winter must guide him in selecting
engine oil for winter use. At the approach of freezing weather
