The effects of unleaded gasolines on the cetane--octane number relationships were investigated. A satisfactory correlation of motor octane numbers with cetane numbers for gasolines in the 75 to 94 motor octane number range was developed which has a standard error of estimate of +- 1.09 appears to be much better than the motor octane number--cetane number correlation. A satisfactory correlation between antiknock index, (R+M)/2 and cetane number with a standard error of estimate of +- 1.31 was also developed. This correlation would have a practical application inasmuch as service station gasoline pumps are currently being posted with antiknock index values as ruled by the Cost of Living Council.
