A process, comprising: providing an olefin feed comprising pentenes, butenes, and isopentane; and alkylating the olefin feed with isobutane using an acidic ionic liquid catalyst; wherein less than 5 mol % of C5 olefins in the olefin feed are converted to isopentane, and the alkylate gasoline has defined final boiling points and high RONs. A process comprising: alkylating an olefin feed comprising pentenes and isopentane, with isobutane using an acidic ionic liquid catalyst; wherein less than 5 mol % of C5 olefins in the olefin feed are converted to isopentane; and wherein an n-pentane product yield is low. An alkylate gasoline, comprising less than 0.1 wt % olefins and aromatics, less than 1.8 wt % C12+hydrocarbons, and greater than 60 wt % combined C8 and C9 hydrocarbons, wherein the trimethylpentane in the C8 hydrocarbons and the trimethylhexane in the C9 hydrocarbons are defined.
