Aug 12 (Reuters) - Russia's Rosneft said on Friday that replacing Russian oil supply via the Druzhba pipeline to the 240,000 barrel-per-day German PCK Schwedt refinery it owns alongside Shell and Eni could cause a "loss" of 300 million euros a year.
Rosneft said the refinery's capacity would be cut by half if supplied only by Rostock. (Writing by Shadia Nasralla; Editing by Leslie Adler)
