Octane is a word familiar to
all motorists, yet few know its
real meaning, in the opinion of
the majority of petroleum sci
entists. Some people think it
refers to a substance, others to
a measure of anti-knock value,
Both are to a certain extent
right, but few of them are sure
just how right they are, or why.
Explains Term
To make the term and its ap
plication to gasoline clear to its
retail salesmen, General Petro
leum Corporation, producers
and distributors of General
Mobilgas, . has prepared a
printed explanation for its em
ployees. Gasoline, the brochure
points out, is a mixture of many
different hydrocarbons, and
these hydrocarbons in turn are
various combinations of hydro
gen and carbon. Scientists have
theoretically isolated many of
these different combinations.
One of them is known as "oc
tane" and contains eight parts
of carbon and eighteen parts
of hydrogen.
Iso-Octane
These parts of carbon and
hydrogen may be grouped in
different arrangements, one of
which is known as "Iso
Octane". It is this synthetic
product which is used as a
standard by which to measure
the anti-knock value of a gaso
line. Because of its hu?h anti
knock tendency, Iso-Octane is
arbitrarily assigned the number
100, while another hydrocarbon
belonging to the heptane fam
ily, containing seven parts car
bon to sixteen parts hydrogen
and which has a very low anti
knock value, is given the num
ber 0.
To determine the octane val
ue of a gasoline, the fuel is
burned in a carefully standar
dized testing engine such as
General Petroleum has in its
Vernon laboratories. By refer
ence to the behavior of octane,
scientists can say this gasoline,
(the one they are testing)
knocks just as much as a theo
retical fuel composed of, say,
68 parts of octane and 32 parts
of heptane. In other words, the
gasoline would have an octane
value of 68, which is nothing
more or less than its anti-knock
rating.
Octane Numbers
The use of an octane number
with reference to gasoline, the
brochure emphasizes, does not
mean that the fuel contains that
percentage of octane, but mere
ly refers to the anti-knock value
of the gasoline as measured by
this scale which is called oc
tane numbers. General Mobil
gas, it was pointed out, has one
of the highest octane ratings oi
any non-premium gasoline on
the market-
RIGID TESTS IN
EXTREME CLIMATE
With lta new product completed
and ready for distribution, Socony
approached the question of practical
teata, according to W. F. Carper, lubri
cating engineer for the General Petro
leum corporation In Portland. At
Lake Placid, New York. In the heart
of the famous Adirondack mountains,
and again at Moose Harbor in the
noted. Hudfon Bay region. In sub-zero
temperatures, the new product, new
Mob II 01 i, went through every form of
practical and competitive demonstra
tion that automotive engineer could
devlae to positively prove Its fluidity.
Its resistance to extreme cold. It not
only passed every requirement, but
was found to excel any competitive
oil on the market.
In the searing, scorching heat of
Defith. Valley, California, the new oil
again met every requirement and
sui passed the performance of all com
petltlve products. For example, with
the thermometer steadily above 120
degrees F., one car, with radiator re
moved, ran continuously for ten
hours with no cooling agent but
Moblloll.
Throughout the United States the
Socony Vacuum test fleet, consisting
of many different makes of cars, put
the new product through lta paces,
and without exception reported re
sults far tn excess of many other
motor oils on the market.
Aeroplane transportation Is becom
ing more and more common every
day. A modern oil must meet the
requirements of this modern trans
portation. A fleet of test planes tried
the new oil for speed, endurance,
consumption, operation, under dif
ferent temperatures and every other
condition and the oil was pronounced
perfect. Today's speeds give motor
oil 9 times the beating It took three
years ago.
Substantial Gain
In General Volume
The substantial gain In gasoline
sales for the General Petroleum cor
poration In Oregon during recent
months Is attributed to the energetic
co-operation of Independent dealers,
as well as company owned operations
by District Manager Hlgglns In a
statement today. State statistics show
that General Petroleum has shown
a larger percentage gain than any
other company during the past few
months, Mr. Hlgglns said, and this
splendid record is a tribute to both
Independent dealers and company
stations.

It had been part of a Jetty and could
not be seen at low water.
