Disclosed herein is a method for preparing a piston-driven engine blended aviation gasoline composition. Blendstock for automotive gasoline containing an oxygen content in an amount that ranges from 0% by weight to 5.0% by weight and a lead content in an amount that ranges from 0 grams per gallon to 0.05 grams per gallon is blended with an octane enhancer and a pressurant, thereby making the piston-driven engine blended aviation gasoline composition. No additional amount of oxygenate or lead is added to the provided blendstock for automotive gasoline, and the method does not include a step of adding an additional amount of oxygenate or lead to the piston-driven engine blended aviation gasoline composition.

A process for converting light paraffins and/or light hydrocarbons to a high octane gasoline composition is disclosed. The process involves: (1) oxidation of iso-paraffins to alkyl hydroperoxides and alcohol; (2) conversion of the alkyl hydroperoxides and alcohol to dialkyl peroxides; and (3) radical coupling of one or more iso-paraffins and/or iso-hydrocarbons using the dialkyl peroxides as radical initiators, thereby forming a gasoline composition comprising gasoline-range molecules including a C7 enriched gasoline composition having a road octane number (RON) greater than 100.
