A process for controlling the composition of a subgrade gasoline so that the subgrade will yield an alcohol-containing gasoline which precisely meets desired specifications when mixed with the desired amount of alcohol. The process involves blending a plurality of blendstocks to produce a subgrade, withdrawing a sample of the subgrade, mixing it with a known amount of alcohol, analyzing the properties of the resulting mixture, and using the analysis results to control and optimize the blending process.
