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 gaso¬line are not considered adequate to represent this type of motor fuel, data for these analyses have not been averaged, but the individual items are tabulated.
