Gulf Coast spot gasoline discounts narrowed for a third consecutive trading day on Wednesday on news of a key gasoline-making unit shutdown at BP's Texas City refinery and thin market participation.

M4-grade regular conventional gasoline for shipment on the now-prompt and final 2012 cycle, the 72nd-cycle, traded up to 18 cents a gallon below January Nymex RBOB, from minus 23 cents on Tuesday. V4-grade premium conventional gasoline traded within recent ranges, at parity to January Nymex.
