RI 2342 Survey of Pacific Coast Petroleum Products

The Bureau of Mines is making a survey of petroleum products manufactured on the Pacific Coast from California crude oils . California crude petroleum is known to differ in some characteristics from the crude oil produced in other parts of the United States , and the claim has been made that the present Federal specifications are unduly severe when applied to the products made from California crudes . The main purpose of the present survey is to determine whether these claims are justified . This report deals only with California gasolines . Other products , such as burning oil , fuel and lubricating oils , will be taken up later . The samples reported were furnished in most cases , by the four large refining companies located on the Pacific Coast , although a number of samples of motor gasoline were purchased in the open market . In Los Angeles , samples of motor gasoline were obtained from service stations representing as many different refineries as possible . Inasmuch as San Francisco is one of the cities covered by the regular semi -annual motor gasoline survey conducted by the Bureau of Mines , it was not considered essential that the set of samples obtained from this city be as comprehensive as would otherwise have been necessary . The gasoline consumed in the States of Washington and Oregon is furnished for the most part by California refineries , and no effort was made to procure samples from these States .
