Keeping Rules Modern.


Like all good car owners, Smith
follows certain basic rules in the be
lief that he saves himself a lot of eX-
pense and trouble and assures him
self OF more satisfactory motoring.
But he makes the equally common
mistake of forgetting to keep his
rules up to date.
He still buys gasoline In small
quantities when he is not planning to
use the car so extensively because OF
evaporation" He pictures his fuel
supply diminishing when the car is
standing That was the picture. it is
true. in the old days when gasoline
was more volatile.
The trouble with all rules In con
nection with motoring is that when
the motorist discovers they have gone
out of date he drops them like poison
never realizing that he has been &C
tardy they again may be coming back
into style. This is the case with gaso

who keep the car in the garage for
any long period should not buy sc
much gas at each filling.

I didn't tell Smith about this eva

would swing to- the opposite extreme
and it Is a foregone conclusion that
he would be several years getting
around to applying the old rule again

ing systems"
I was referring to full pressure
fabrication. where oil is forced
through the hollow crankshaft anC
sometimes up into the connecting
rods. This oil moves rapidly and is
under such high pressure at high
speed that 1t shoots up to the cylinder
walls and the piston pins, lubricatins
them generously when they neeC
fabrication very badly.
Now if the new car is driven alone
at just about 20 miles an hour witt
its engine turning over at a compare
lively slow rate the oil does no
shoot up to the cylinder walls as
much as it should. Now if the driver
will just step on the gas for a few
minutes occasionally during the
breakingin process, the cylinders viii
getsa good bath of oil. Besides a little
acceleration in the oil flow brings into
the system a greater quantity of lubri
cant, which is another way of saying
that the quality is momentarily
raised.
