Use Good Gasoline - Hudson Super Six 1916 Reference Book

Bear in mind, however, that reducing the proportion of gasoline to air, gives a little less power and
acceleration. Setting it in the right proportion (which must be found by adjustment, according to climatic
conditions), results in maximum power and consequently a little higher fuel consumption than some owners wish
to tolerate.
Setting it to give too rich a mixture results in carbonization, misfiring and increases the wear and tear on the
moving parts of the motor.
IF YOU FIND IT NECESSARY TO ENRICH THE MIXTURE FOR STARTING PURPOSES, DO NOT
FORGET TO RE-ADJUST IT TO THE LEAN POSITION AS SOON AS THE MOTOR WARMS UP.
Do not have the air control ]ever in the "hot" position when driving more than 25 miles an hour. The
increased resistance to the air intake causes proportionately greater throttle opening than is necessary for the
power developed and results in excessive gasoline consumption.
Those owners who live in territories where extremely cold weather prevails in the winter, will be interested in
knowing the advantages of using high grade gasoline. The common fuel sold as gasoline is extremely low test and
seems to be deteriorating in quality each year. As a fuel, it leaves a great deal to be desired, but for obvious
reasons must be endured, either until a better grade is manufactured for universal consumption, or a new fuel is
evolved.
At temperatures ranging from 20 deg. F. to 5 deg. below zero, the low test fuel will be proportionately
difficult to ignite when cold, and at 5 deg. below zero it will be practically impossible to ignite it.
It should be borne in mind that high test gasoline may cost two or three cents more per gallon, but the amount
of gasoline used in warming up the motor will be much less, and therefore the general economy will be increased.
It will not actually result in a saving in fuel cost, but it will mean much less annoyance and, at least, not more than
equal cost.
With a low grade fuel, it is necessary to choke the motor and frequently to prime it before the fuel will ignite
and the motor can be started. It is then necessary to run the motor with the choke closed for two or three minutes
in order to get it hot enough to get the benefit of the hot air pipe and aid in volatilizing the fuel and eliminating the
necessity of the choke. Even with the low grade fuel, the carburetor will operate satisfactorily in the winter time
if the motor be thoroughly warmed up before the car is driven. With the high grade gasoline, it may be necessary
to use the choke to start the motor, but it will be possible to get it into the hot air position immediately after
starting.
It should be understood that when the choke is closed, the suction in the carburetor is terrific and the volume
of gasoline drawn out and used to run the motor for three or four minutes under these conditions would ordinarily
run the car a mile. This is why gasoline economy decreases in cold weather. The less the necessity for using the
choker, the greater the economy, hence the reason for keeping the motor warm whenever possible and using high
grade fuel.
Every Hudson owner should try a tank full of 70 test gasoline. He will soon be convinced that it is well worth
the extra cost.
If the car is stored in a cold garage, and difficulty is experienced in starting up in the mornings it would be
well to consider the installation of a cheap stove or heating device to keep the temperature in the immediate
vicinity of the engine not lower than 30 deg. A small thermometer is a very handy article in any garage in winter,
as it will usually explain reasons for the long time it takes to start the motor. This must be taken into consideration
before complaining.
