Poland's PKN sees Russian crude quality improving within days

Poland's biggest refiner PKN Orlen expects the quality of Russian oil in the Druzba pipeline supplying Poland to improve within days, a board member said on Thursday.

"We are receiving signals that on sections of the Druzba pipeline which are not in Poland the quality of oil may now be better," Zbigniew Leszczynski said.

"As a result of this, we expect that the quality of oil will improve in the coming days."
