Basic Factors Affected by

| The correct fabrication of nm auto.
mobile, truck or tractor motor de.
pends on the following three condi-
tions, all within the control OF the
operator: The use Of lubrlcnting oil
or the highest quality; the use Of the
correct grade OF this high-quality oil
TO meet the engine operating condl-
lions exactly; proper precautions to
maintain the quality of the lubricant
while In service and to make adjust
ments to insure its delivery in exactly
the correct quantities to the friction
surfaces.
Failure OF the operator to give the
necessary attention to any one of
these conditions may result in I'M
paired performance. The lubricant
plays vital part in insuring smooth,
regular operation and the malnte-
nance Of power output at it's maxi
mum; or increased operating costs
Repairs due TO incorrect fabrication
are frequent and costly. Also, the use
OF the wrong oil or the improper use
OF the correct oil tends to increase
fuel consumption. the number of
forced stops and the rate Of dcprecl-
alton.
Few Simple Precautions.
With SO much dependent on the cor
rect fabrication OF your engine, il
would be unwise to neglect the few
simple precautions necessary to in
sure the very best Of results.
n oh Ne
any particular engine is a matter for
competent engineer. 1t involves the
following four basic lubricating fac.
tors affected by engine design:
First-Enginc operating tempcra-
turc depends primarily on the service
or loading Of the engine. The steady.
uninterrupted, almost full-lond work
OF the tractor engine determines high
temperatures as contrastcd with the
intermittent variablc-load work en-
countercd by the truck or passenger
car engine. The engine size, the
capacity of the cooling system and the
fuel used are some Of the other fca-
lures Of design which have IL bear
Ing on operating temperatures. AS
all oil tends to lose body or thin out
under heat we are naturally inilu-
cnccd toward the use of heavier
bodied oils where operating tcmpcra
lures are high.
Distribution of Oil.
Sccond--Oil distribution. The ability
Of the lubricatng system to distribute
the oil to all friction surfaces where
the lubricant is chilled and thickcned
determines how fluid the correct oil
must be. In other words this feature
Of engine design is the limiting factor
with respect TO oil body.
Some lubricating systems are
adapted for perfect circulation OF nll
oils from the heaviest bodied to the
lightcst others function best on oils
Of light or medium body.
The correct oil is Of such body as
to perfectly distribute through tho
atmospheric temperatures likely to be
encountered in service.
Not All Burn Equally Well.
Third-Carhon formation. Not NIL
oils are equally clcan-burning, nor are
all engines equally sensitive" to the
baneful effects Of carbon formation.
The correct oil will he OF such char.
acter rs to minimize carbon formation
and the troubles which result from
such deposit.
Fourtll-Scal for piston rings. The
correct oil will be Of ample body and !
correct character TO seal the piston
rings against passage OF the highly
compressed gases on the compression |
and power strokes. Such sealing is
essential to conserve power, increase
fuel economy ana forestall excessive |
dilution OF the oil supply with fuel |
and contamination by water and other
foreign substances. Plainly, the sub
5ect is an intricate one, the subject
with which the average operator is at
disadvantage.
