NATIONAL MOTOR-GASOLINE SURVEY, WINTER 1946-47./
By 0. C. Blade/
This report on the properties of motor fuels sold through service stations
in the United States is a continuation of a series of reports made in accord-
ance with a cooperative agreement between the Coordinating Fuel Research (CFR)
Committee of the Coordinating Research Council (CRC)3/ and the Bureau of Mines
of the United States Department of the Interior. The first of these reports
presented data on motor gasolines sold during the winter of 1935-36. / Further
reports were issued describing motor gasolines sold during the succeeding sum-
mers and winters to and including the summer of 1941.4/ No reports were made
on motor gasolines sold during the winter of 1941-42 and during the summer of
1942. However, starting with the winter of 1942-43, the semiannual reports
The present report presents analytical data for 4,544 samples, represent-
ing the products of 124 companies. The samples represented in this report were
obtained during December 1946, January and February 1947. As in previous sur-
veys, the companies covered by the survey include both large and small suppliers.
Conforming to former reports, the data cover three groups of samples - regular-
price, premium-price, and third-grade gasolines.
As the number of analyses submitted for samples of third-grade gasoline
are not considered adequate to represent this type of motor fuel, data for the
analyses have not been averaged, but the individual items are tabulated. The
number of samples, items, and brands comprising each group is as follows:
Regular-price, 2,368 samples, 319 items, and 113 brands; premium-price, 2,172
samples, 289 items, and 106 brands; third-grade, 4 samples, 4 items, and 4
brands. The meanings of these terms as used in the surveys are as follows:
Sample: The individual supply of gasoline obtained at the
filling station and analyzed in the laboratory.
