IMPORTANT CARE
OF LUBRICAT|0N
One Part of Car That Must Be
Right and Needs Special Care
in Cold Weather.
KEROSENE IS GOOD CLEANSER
When Freezing Weather Arrives Test
Oil to See II II 10 Adapted to New
Conditions - Do Not Permit
Water to Accumulate.

Do not neglect to overhaul your
lubricating system until winter is far
advanced. 1t is a job which the ordi-
nary man avoids because 1t gets his
hands dirty. But serious trouble may
follow II the work is not done In time
writes Albert N. Atkinson In the New
York World. Winter. with Its low
temperature. brings unusual conditions,
and the various lubricants used on a
car must be adapted to the change.
Doubtless the oil In the crank case
has been changed every 1000 to 1900
miles during the summer, a rule which
should be followed all winter. But
frequently the motorist neglects to
clean out the crank case when chang
Ing oils and so the dirt and grit re-
main In the bottom of the stump to
contaminate the new oil.
Use Kerosene Method.
Properly the oil base should be re-
moved and the strainer, pump and
piples thoroughly cleaned. A new
gasket must then be fitted around the
Joints. This Is more OF n job than the
average man wishes to undertake, so
the kerosene method may be consld-
cred fairly satisfactory.
Before putting In the new oil let
us consider whether II is adapted to
the new season or not. The working
temperature will be the same. but the
oil stump Is exposed to every blast Of
cold air coming through the radiator
and the oil may be chilled to a point
where 1t cannot flow. AS soon as
freezing weather arrives make a cold
test OF the oil as follows: place half
a tumbler OF the oil In some exposed
place where II may be acted on by
h outside temperature. Watch II
from day TO day. II II thickens I'D
and refuses 10 run at any time II is
not suited TO your engine. Use n
slightly thinner oil or one which will
not be too sluggish at the low tenn
peratures usually met at your lati-
tude. II i~nconvenient or impossible to
change the oil Immediately. keep the
car In a warm place and do not take
II out until the engine has run ten
minutes or so and warmed up the oil.
The hot oil flowing back into the
stump soon brings II to n temperature
where the cold win have no bad effect
upon II. II obliged TO let the car
stand any length OF time with engine
not running. you will OF course blan-
ket the radiator which not only pro-
tects the cooling system but the oil
as well.
Danger often Overlooked.
There is one danger which Is fire.
quently overlooked and that In an ac-
emulation of water at the bottom Of
the stump or oil well. This comes
from the products OF combustion leak
Ing past the piston and also from oc-
c%aslonal leakage of the cooling system.
II the stump is exposed to freezing
temperature this water will freeze. II
there Is enough Of It, some may freeze
In the oil pump. wrecking 1t. SO draw
Off a little oil from the bottom OF the
stump at least once a week. carefully
draining out all water, II found.
Change the grease I'm the gear-case
and d%ifferentlal ease to a heavy oil.
A semi-fiuid grease or gear compound
Will thicken up In winter and will
not penetrate where II should.
SO pay careful attention 10 these de-
tails. MS fabrication OF the car is n
matter which simply MUST be right.
