The number of samples, items, and brands comprising each group is
as followss Regular-price, 2,011 samples, 312 items, and 129 brands;
premium=-price, 1,800 samples, 27), items, and 108 brands. The meanings
of these terms as used in the survey are as follows:

Sample: The individual supply of gasoline obtained at the
Filling station and analyzed in the laboratorye

Brand: The gasoline sold in a given price group under a
Ziven trade name. The figure representing the total number
of brands sometimes is only approximate, because in some
cases the name of the marketer is not reported.

Item: The index number assigned to a given brand in a given
marketing area or district. The data for each item represent
the average of those submitted for that brand in any one
particular area. There is no relationship between the same
item numbers of different districts in table l.

The arrangement of marketing districts used in the three preceding
reports has been continued (see fige 3). This arrangement comprises 17
districts which have been selected with reference to the specifications
on motor gasolines, petroleum-refinery locations, population centers,
and arteries of commerce such as navigable rivers. The States or parts
of States in each district are indicated in the headings of table 1.

Characteristics of regular- and premium-price motor gasolines are
reported, based upon data contributed through the American Petroleum
Institute for compilation by the Bureau of Minese

EXPLANATION OF TABLES AND FIGURES

In table 1 are shown data for gravity, corrosion, sulfur, gum, T.Eele
(tetraethyllead), research and motor method octane numbers, Reid vapor
pressure, and distillation characteristics for motor fuels sold in 17
marketing districts in the United States during the winter 198-9. Pre-
ceding those values in table 1 are given, in the second colum, the number
of samples of gasoline represented for each iteme the data for a given item
are the average values of results submitted on that brand from the district
designated. The tests were made according to procedures standardized by the
American Society for Testing Materials, and the A.S.T.M. method designations
are shown in the colum headings. The data reported for the gum tests fall
into two classes — those that represent true gum and data on "gums" that are

oily in character and therefore abnormally high. In the tables only
those values that appear to represent true gum content are reported; all
other results are reported as oily.” Octane numbers included in this
report hy been determined by both the A.S.T.M. motor and research
methodse</ The distillation temperatures have been corrected to a common
pressure, that of sea level, and are on the “percent evaporated" basis.
Averages for regular=- and premium=price gasolines are given at the foot
of each colum of table 1. On the tw lines following the averages are
shown the minimum and maximum values of each grade of gasoline in that
district.

The averages of table 1 have been assembled in table 2, The fourth
colum in table 2, headed "Items (Brands), indicates the numbers of
brands in the districts whose averages are here summrized. Thus, the
data listed for a given district are averages of figures of that number
of items ard not of the number of samples shown in the third colum,
although that many samples are represented. The figures at the foot of
each column of data are national averages based on 17 districts. Table
3 gives the minimum, maximum, and average figures for each characteristic
of the regular- and premium-price gasolines. Table shows similar
figures for the winter survey of 1917-8.

Figure 1 is a plot of the average data for octane number (motor
method), vapor pressure, and certain distillation points, taken from
tables 2 and 3 of the reports for the winter surveys beginning with
1935-36 and for research octane numbers beginning with 1912-13, Figure
2 is a similar plot of data from tables 2 and 3 of the reports for the
summer surveys beginning with 1936 with the exception of research octane
number which begins with 1943.

Detailed information regarding the geographical sources of the samples
is given in table 5. The system used in identifying sample sources is as
follows: The entire country is divided into 17 districts, as shown on the
map (fig. 3), and as listed in table 6; within each district are one or more
"locations," named for the principal city in that immediate vicinity, many
locations include neighboring cities and towns in addition to the principal
citys The complete listing of districts, locations, and cities, together
with the respective number of samples for each, are presented in table 5.

Premium-price gasolines have an average motor-method octane rating
of 7907, compared with 79.4 for the winter of 1917-8, and with 78.5,
8009, and 75.1 for the preceding three winters, respectively. Regular=
price gasolines have an average octane number of 7566, compared with
75e3 for the winter before, and with 7500, 75.9, and 702, respectively,
for the three preceding winterse

The average research-method octane number of premium-price motor
fuels is 86.5 for the survey just completed. This compares with 86.2
for the winter of 197-8, and with 85.0, 87.7, and 80.5 for the pre-
ceding three winters, respectively. The average research octane value
for regular-price gasolines is 80.5, and compares with 80.2 for the
winter before, and with 80.1, 81.7, and 7.2, respectively, for the
three winters precedinge

The motor fuels also are somewhat more volatile than those of
recent years. The average Reid vapor pressure of premium-price motor
fuels during the past winter is 10.) pounds, which compares with 10.2,
10.1, 10.0, and 9.0 pounds, respectively, for the four preceding winters
back to 19l-l5. ‘The average vapor pressure of regular-price gasolines
is 10.2 pounds, compared with 10.1, 10.1, 968, and 9.2 pounds for the
same winters, respectively. The average figures from the distillation
data in the present survey indicate only small changes compared with
data from surveys of the three years preceding.

These data reflect the most important trends in the quality of
winter motor gasoline since the close of the war and advent of more
settled conditions. The table of average values and the set of charts
on the following page illustrate the comparisons for this period, as
well as comparisons with the gasolines sold during the last year of the
war and the first post-war winter.

Data compiled on other tests included in the present survey and their
average values ares Gravity, 62.5° AsPeI. for premium-price and 62.0° A.Pele
for regular-price gasoline. Corrosion, negative for all but two of the
samples tested. Sulfur content, 0.076 percent for premium- and 0.092 per-
cent for regular-price motor fuel. Gum-test results, 202 mg. per 100 mle
for premium- and 2.1 mg. per 100 ml. for regular=grade gasoline. Tetra-
ethyllead contents, 1.88 ml. per gal. and 1.35 ml. per gal. for the two
grades, respectively.

The present report presents analytical data for 3,811 samples, re-
presenting the products of approximately 130 companies. The samples
represented in this report were obtained during December 19,8 and January
and February 1949. As in previous surveys the gasolines covered by this
survey include those from both large and small suppliers. The data cover
two groups of samples—regular-price and premium-price gasolinese

UNITED STATES DEPARTMENT OF THE INTERIOR - BUREAU OF MINES

NATIONAL MOTOR-GASOLINE SURVEY, WINTER 19)8-),92/
By 0. Ce Blade2/
INTRODUCTION

This report on the properties of motor fuels sold through service
stations in the United States was made in accordance with a cooperative
agreement between the American Petroleum Institute and the Bureau of
Mines of the United States Department of the Interior. This paper is a
continuation of a series made in cooperation with the Coordinating Fuel
Research (CFR) Committee of the Coordinating Research Council (CRC), Ince
The first of this series of reports presented data on motor gasolines
sold during the winter of 1935-36, and succeeding reports described motor
gasolines ,sold during the summers and winters to and including the summer
of 191.3/ No reports were made on motor gasolines sold during the winter
of 1941-2 and during the summer of 192. However, sta: syne with the
winter of 192-3, the semiannual reports were resumed.:

SUMMARY

A continuation of the slight upward trend in octane numbers of motor
gasolines in the United States is indicated by the results of the national
motor-gasoline survey for the winter 198-49. The average octane values
(motor and research methods) are well above those of the winter of 19hh=-l53
they are not as high as those of the winter 195-46, when wartime re-
strictions were removed, but the three winter surveys following, including
1948-49, have shown successive small increments in octane number.

Results of the compilation of the past winter's survey of motor fuels
from filling stations throughout the country indicate the following:
