Engine Lubrication - Chevrolet Fleetmaster Series 1947 Owner's Manual

GENERAL LUBRICATJ;'ON
Your Chevrolet dealer is equipped to render complete Chev-
rolet Specialized Lubrication Service. We recommend that you
take advantage of his modern equipment and trained men.
Lubricants are less expensive than repair bills, and should be
applied regularly if you are to obtain a maximum of useful serv-
ice from your car.
It
is, consequently, important that the proper
grade of lubricants be used in accord with a definite schedule.
In your selection of the proper brand of oil, it is desirable to
consider the reputation of the refiner or marketer. He is respon-
sible for the quality of his product and his reputation is the car
owner's best indication of quality.
ENGINE LUBRICATION
Your use of the proper engine oil is one of great importance in
obtaining maximum performance and satisfaction from your car.
It
is imperative that the recommended light oils be used in
the engine during the "breaking-in" period.
Light oils assure a better "breaking-in" of the engine, as they
assure ease of starting the engine, prompt flow of a sufficient
quantity of oil to the bearings, less friction between moving parts,
less wear of moving parts, etc.
Types of Oils -
Crankcase oils in
service, unless
pro!~cted
against oxidation, may form sludge and
varnish and under some conditions corrosive acids.
To minimize the formation of these harmful decomposition
products and to supply the type of oil best suited for the different
operating conditions, the oil industry markets several types of
crankcase oils. These types are defined by the General Com-
mittee, Division of Marketing, of the American Petroleum Insti-
tute as follows:
"REGULAR MOTOR OIL, this term shall be used to
designate a straight mineral oil. Oils of this type are gen-
erally suitable for use in internal combustion engines under
moderate operating conditions."
