Petrom increased the price of diesel fuel by 0.3 lei a liter at all its filling stations in Moldova on Monday, April 4, Alexei Taram, a representative of the company's Sales Department, has told Info-Prim Neo. He did not yet provide explanations for such a move. The diesel oil at the Petrom service stations now costs 15.19 lei a liter, as against 14.89 lei a liter earlier. Two smaller oil companies also raised the price of diesel fuel on Monday. Twenty companies imported and sold wholesale gasoline and diesel fuel last year.
