Auto Drivers Interested in
Saving Fuel Bills.
RICH MIXTURE COSTLY
Every Possible Caxe Should Be
Taken to Insure Proper Igni-- ".
tlon and Motor Repair.
There is every indication that In
the coming summer we are going- to
have a period of high prices in the
Kasoline field. Understand, there is no
shortage of motor fuel; there is plenty
to go around, but the producers seem
to feel that they are justified in rais
ing prices, and unless all signs fail
they are going to do it- This being so.
every car owner in America is vitally
interested In saving all the fuel that
he possibly can. We have been ex
tremely wasteful of our fuel in the
past and the wise motorist will wel
come suggestions that will enable him
to eliminate waste of all kinds and
thereby reduce his mounting bills.
Here the principal leaks take place,
and these must be stopped before real
fuel efficiency can be hoped for. It is
rather amusing to see ambitious car
owners Install certain types of devices
in connection with the carburetion
system, when if they only knew how
to adjust the carburetor properly
nothing of the sort would be neces
sary. -The modern internal combustion en
gine will operate on a fuel mixture
ranging from eight parts of air to one
of gasoline to 14 parts of air to one
of gasoline. Operating conditions,
however, are better when, the mixture
, , . .. - . ... . . 11 1 .athpr
is leaner. iaai ia iw ' 1 w .
than 8 to 1. But as a general rule car
owners tend to use a mixture nearer
the latter than the lormer.
Don't Have It Too Rich.
Obviously a mixture at 8 to 1 con
tains almost twice as much gas as one
t 14 to 1. If the engine ran better
with the richer mixture there might
be some excuse for . using it, but it
doesn't. Further, the richer mixture
tends to produce rapid carbonization,
and while the engine will assimilate
it. nevertheless the action ife sluggish
and lacks the snap that is present
with the leaner ranges.
Therefore the first thing the car
wner who aims at maximum effi
ciency should do is to make sure that
his carburetor is properly adjusted
to give the leanest mixture consistent
with satisfactory running. If the car
owner Is unable to make this simple
adjustment himself he should certain
ly have the service station do it for
him.
In cases where the carburetor Is an
old instrument with not enough range
of air volume it may be wise to install
one of the devices of the auxiliary
air inlet type. These are inexpensive
and easily put in," place. At any rate,
every car owner should give his earn
est attention to-the carburetion sys
tem with a view to reducing the very
probable waste in' this locality.
Before we leave the carburetion sys
tem we may suggest that many mod
ern cars will satisfactorily operate on
a mixture of gasoline and kerosene. If
the individual owner will try this ex
periment, using, say, four gallons of
gasoline to one of kerosene, he may
be pleasantly surprised, at any rate it
ia worth-the attempt. This is particu
larly so in warm weather, when this
heavier mixture vaporizes more read
ily. Keep Battery Filled.
Now the carburetion may be never
ho good, but if the ignition is not up
to the mark maximum efficiency can
never be reached. Therefore it be
hooves the car owner to keep the bat
tery fully charged and filled with dis
tilled water, as ho has been warned
id often to do. The cable connections
at plugs and ignition unit and coil
must be kept clean and tight. It does
not one atom of good to get a fine ex
plosive charge in the cylinders unless
there is. a good hot spark to ignite it.
These two items of carburetion and
ignition may be termed the major
'Offensives in the campaign to get
fuel economy; there are still numbers
of machine-gun nests to be cleaned up
before you have reached perfection.
There are many places in the fuel sys
tem where leaks may develop, and a
direct leak-in the fuel line is a pro
digious waster of gasoline.
Moreover, a small leak is hard to
detect; if the car owner has noticed a
sudden increase in the amount of gas
oline used, this may be the cause. At

so over the whole fuel system occa
sionally examining it for leaks.
Also the fuel system, with its filters
, and screens, needs a periodic cleaning
out. It will be remarkable hpw much
better the engine runs- after the fuel
line has been cleaned out to give an
unobstructed flow to the gasoline.
After this the muffler will probablj
be the better for a little attention A
, clogged muffler consumes power thai
ought to be employed In driving thh
car. - - ; : '.
Carbon Wastes Fuel.
Another fruitful source of fuel
waste is carbon in the cylinders. A
carbonized engine uses much more
fuel than a clean one. Scrape the-. cyl
inders as one-of the first skirmishes
in the fuel reduction campaign.
In some instances, where an engine
is an excessive carbonizer. it may be
well to install one of the water feed
ing devices or vaporizers, of which
there are scores on the market, after
" the .cylinders have -been thoroughly
cleaned of all carbon deposits. These
devices will prevent the formation of
carbon In clean -cylinders, though-. I
doubt that they will remove heavy
deposits without assistance.
The valve system must be in excel
lent working order . or heavy fuel
waste may result. The valves must
seat properly or they will let the fuel
mixture leak out without, performing
its appointed function or only partly

at best. Any car owner who has ex
perienced the pleasure of driving im
mediately after the valves have, been
ground will need no advice in regard
to having the valves ground 'at fre
quent intervals.
Have you ever stopped to realize
that every waste of power is really a
waste of gasoline. If gasoline is ex
ploded and the power so generated is
wasted or only partly used this
amounts practically to waste of fuel.
If lubrication is not kept up to the
mark the friction between moving,
parts wastes power. Therefore be par
ticular to lubricate -all parts of the
mechanism as indicated on the chart
or in the instruction book given with
the car.
The clutch, while it is usually a well
behaved piece of mechanism, when it
develops trouble is an enormous pow
er and hence fuel waster.- When the
clutch slips it is letting power slip
away,- not to mention the damage to
the part itself and the unsatisfactory
action of the car.
Misaligned wheels are another trou
ble that results in wasted power and
fuel. When the wheels are running
out of true a scraping is set up be
tween the tire and the road, which
not only tears the tire to pieces in a
short time, but also wastes fuel.
It is the only wise plan to have "the
wheel alignment checked ug twice a
year, and oftener if the" car has suf
fered a severe bump or for any. other
reason the owner suspects that the
wheels are out of line. In connection
with the wheels, a dragging brake
will materially increase the consump
tion of power. It is so easy to adjust
modern , braking aystems that there is
no excuse 'for letting these parts re
main in a condition that ia bad for
them and worse for the general oper
ation of the car.
Finally, the car owner can save a
great deal of fuel by careful operation
of his vehicle. He' should learn to
coast wherever possible, shutting off
the ignition on long hills, with the
throttle closed.
Useless idling of the engine costs
many thousands of gallons of fuel in
the course of the year in this country.
Do not waste fuel around the garage
for washing parts, etc. Kerosene does
Just as welt as gasoline, for washing
metal parts and it is not so valuable
today as gasoline.'

Racer Declares That ; When- Tire

'You hear a bang, your car . gives
a lurch, and the next two seconds tell
whether you're a dead one or not."
Such isBarney Oldfleld's concise
description" of what happens when a
tire blows out under a car. that is
traveling, at racing speed. .
"If you can meet that first '.lurch
with just the right twist of the wheel
to keep your car headed straight to

steering wheel too far over, only a
miracle is going to save- you and
your mechanic, especially if your
blow-out has taken place on a turn,
as it usually ' does."
The one thing the race driver most
deeply dreads is a tire accident. It
was this factor that led Mr. Oldfield
himself into the long series of tire
experiments which . gained him his

to compete for the national prize,
first must have won one of the prizes
to be awarded by various organisa
tions and individuals in their re
epective communities. The national
prize is to be known as the H. S.
Firestone Uunlverslty scholarship and
will be given. in any college or uni
versity chosen by the winner. All
high school pupils may submit a 500
word .essay, which must be entitled
"Ship by Truck and Good Roads."
but if the national prize is won by
any pupil other than a" senior the
award will be deferred until the win
ner is ready to matriculate at the
institution of his choice. ;
Judges who will make the national
award will be named by Commis
sioner Claxton before. May . 22, by
which time all essays must , be sub

principals of high schools are being
acquainted this week with the terms
of the contest, and, it is expected,
more than 1,000.000 essays will be
written upon this subject, serving
to accentuate the interest and to
widen- the scope of discussion to be
created by Ship by Truck-Good Roads

LOSS ' OF POWER TOO GREAT
Clogged MulTler AVill Reduce Effi-
V.. ciency, of Auto Engine.
According to a writer in the cur
rent issue of American Motorist, there
are a- number of causes which -con-tribute
to power losses in an engine.
not the least of which is a partially
stopped up or clogged muffler.
It is natural that the often narrow
and tortuous passages of the muffler
should be choked with carbon after a
year's use, he says, but very often
remarkable improvement in engine
efficiency is secured with no greater
trouble than a temporary cleaning of
the muffler, which should be beaten
with a wooden mallet or a piece of
wood; this will loosen the worst ac
cumulations, which will then be blown
out through the tail pipe. If the car
is equipped with a muffler cutout and
there is a noticeable difference in
power when the cutout is closed and
open, a cleaning of the muffler.'as- in
dicated, should be undertaken at once.

Device Declared to Be as Errcctive
In Summer a In Winter In -Saving
or Fuel.
Every motorist has heard so much
about saving gasoline in '"winter., that
the advisability of saving It in sum
mer has been .somewhat: overlooked.
Yet it is possible to save -gasoline-on
even the hottest days -of-'iuramcr, es
pecially in starting t he car, - - "- "
"The application -of the- thermostat
to the motor car makes gasoline sav
ing in summer time possible," says A.
M. Beaver. "The Columbia car. for
instance, has- a powerful thermostat
which automatically opens and closes
the radiator shutters with which this
car is equipped. When the engine is
cold the- shutters . are closed "This
cuts off the air from. 'the engine,
which -in- turn -warms up - more
quickly than if the radiator is with
out shutters, letting the fan send back
a full stream. of air.
"The beauty of this feature is its
effectiveness' in winter. On the cold
est days expensive hood covers are
unnecessary and the engine warms up
quickly to the most efficient running
temperature.
"This efficient running temperature
is about 180 degrees, considerably
more than the temperature of the hot
test days of summer. Suppose the
temperature is 90. That of the en
gine before starting would also be
about 90. perhaps a little less. The
engine then would have to be warmed
up to 180 degrees. Ths more quickly
this is done the less gasoline waste.
"And with the - price of gasoline
going up from time to time, every
pint saved is money in the pocket of
the car owner. That is just what the
thermostat and shutters on the Co
lumbia do." "

walking pedestrians, whose nervous

Jay walking will be forbidden. But
the most important rule of all is that

Under no circumstances must a pe

the traffic man.
The traffic cop must lead the crowd

breath and wind his klaxon for

north and south. Then he, the cop,
will take his place at the head of

it. After depositing pedestrian traffic
on the protecting curb of the opposite
sidewalk, the traffic cop will return
to the center of the street.
Then he will take another breath,
sound his horn once more and lead
the pedestrian procession west to
east, after which ke will return to
his post. Then the traffic cop will
sound his siren once again, this time
signifying that traffic is to move
south from north, and lead the pe

. . - ;
The reason you are interested in the name on your tire i
that it identifies the maker. By knowing the maker you can
judge his ideals of manufacture.
The only secret of a super-tire lies in the principles of the.
maker. His standards decide the quality. For there are na
secrets in the tire industry.
.What you get depends on what is behind the name on your)
tire. Brunswick, as you know, means a very old concern
jealous of its good name. Since 1845 the House of Brunswick
has been famous the world over for the quality of its products
The Brunswick Tire is all that you expect? and more.
Your first one will be a revelation. YouH agjee that you've
