AFTER THE past two weeks of decline, gasoline prices this week will rise by P0.90 per liter (/L), while the prices of diesel products will increase by P0.80/L, the same amount that was cut two weeks ago. Kerosene will cost higher by P0.75/L this week, oil companies said in their advisories as of late afternoon on Monday. For most of them, the price adjustment will take place at 6:00 a.m. today, May 21. Last week, the per liter prices of gasoline and kerosene were slashed by P1.25 and P0.30, respectively. Diesel prices were unchanged during that period. The price adjustment reflects the movement of prices in the international market, the oil companies said. — Victor V. Saulon
