OIL COMPANIES are raising the prices of major petroleum products this week, with gasoline going on its third week of hike. Diesel will rise by P0.60 per liter (/L) after staying unchanged last week, while kerosene will increase by P0.45/L coming from last week’s P0.20 hike. Gasoline will move up by P0.10/L. For most of the oil companies, the price adjustment will take place at 6:00 a.m. today. So far this month, oil prices have increased after initially starting the month with a price cut. Gasoline prices have consistently rose, while diesel and kerosene had one week each of staying unchanged. — Victor V. Saulon
