An improved process combination is disclosed for the production of an oxygenated gasoline component from an FCC gasoline feed. Olefins in the cracked gasoline are isomerized using a medium-pore molecular-sieve catalyst to achieve high yields of C.sub.5 + isomerized gasoline and avoid conversion of highly branched paraffins to equilibrium values. The isomerized gasoline is etherified to obtain oxygenated gasoline.
