RI 3374 Cooperative Fuel Research Motor-Gasoline Survey, Summer 1937 ? Introduction

This is the fourth in a series of reports on properties of commercial motor fuels, made in accordance with a cooperative agreement between the Cooperative Fuel Research (C.F.R.) Committee and the Bureau of Mines of the Department of the Interior. The first report gave data on motor gasolines sold during the winter of 1935-363/. The second report gave the same data? for motor gasolines sold during the summer of 19364/. The third report of the series gave the same data for motor gasolines sold during the winter of 1936-375/. This report covers 63 brands of gasoline represented by 1,136 samples excluding the Pacific Coast. Those from the Pacific Coast were averaged by the Pacific Coast technical group before being submitted and are published exactly as they were submitted. In some areas reports were received from five or six companies on the same brands of gasoline, whereas in other areas only one company reported on a brand. Thus, it can be seen that some of the data are more representative than others.
