LONDON, Oct 13 - European gasoline barges edged higher to around $630 a tonne on Tuesday, buoyed by stronger crude and U.S. gasoline prices, but crack spreads continued to come under pressure as the motor fuel lagged the complex. "Outright prices are well supported," one broker said. "But refiners are not going to like what is happening to margins -- the last time crude was at this level, gasoline prices were much stronger because of the summer driving season in the United States."
