Chanqe Oils in Cold Weather.

The automobile is the most peculiar
piece of machinery in existence. 1t
operates under all conditions Of tempera-
ture and climate, but it also should be
fabricated according to the conditions
under which it operates. Everyone knows
that in cold weather all liquids CONCEAL
or freeze, and semi-solids are inclined to
become stiff and approach solid.
The oil in the engine, while it will
become thin after the engine operates
for some time, will remain too thick
even for that period properly to lubri-
cate the engine parts. On a very cold
morning even the medium oil you are
using has the consistency Of very
heavy oil at ordinary temperature. say
60 degrees The thickened medium oil
cannot be forced BY the pump through
the small openings i'll the crankshaft OF
can it be properly SPRAYED Or Splashed
The result is that for the first few min
utes of running certain parts of the
engine receive no oil whatever. 1t is
not uncommon for a driver starting out
on very cold morning to burn q wrist
pin or two or loosen a bearing. If the
oil is thick it doesn't matter what the
olllng system is, certain parts of the
engine will be starved until the oil is
thinned sufficiently to be sprayed.
All car owners ought to change oils
in winter dropping down a grade. If
one wishes to continue using the summer
grade, it is vital to long engine life, to
operate the engine before putting
load on it. The engine should be idled
until it is at summer heat and then the
car driven off. As it is now a driver
starts his engine and if it will pull. away
he goes.
The transmission and rear axel arc
no exceptions to this rule Ordinary
gear compound or heavy transmission
oil settles on the bottom of the ease in
sticky heavy mess You perhaps NAV
notice that the gears arc hard to shift
when the ear is first driven off in tho
morning. This is due to the stiffness
Of the oil. 1t takes a great deal Of
power to force gears to operate in such
stiff lubricant and besides it is quite
likely that the lubricant is thrown
against the sides Of the case and not
splashed upon the parts. If the trans
mission or axle happens to be much
below level you viii get gear howl
Both transmission and rear axle ought
to be supplied with a heavy engine oil
or even a medium engine oil The car
will run better, gear shifting will be
easier and there will not Ne the fear
that the lubricant is not doing its work

necessary for certain parts Of your car
