AFTER eight straight weeks of decreases, the price of gasoline will rise by P0.40 per liter (/L) this week, oil companies advised on Monday. The prices of diesel and kerosene, meanwhile, will be on their ninth consecutive week of decline. Diesel will be cheaper by P0.10/L, while kerosene by P0.45/L. For most of the companies, the price adjustments will take place today at 6:00 a.m. “These reflect movements in the international oil market,” Petron Corp. said in its advisory. — Victor V. Saulon
