OIL COMPANIES are rolling back the prices of gasoline and diesel products this week, both by P0.10 per liter (/L) while increasing by the same amount the cost of kerosene. For most of them, the price adjustment will take place at 6:00 a.m. today, Aug. 27. Phoenix Petroleum Philippines, Inc., PTT Philippines Corp., and Pilipinas Shell Petroleum Corp. were the first three companies that sent their advisories during the weekend. “These reflect movements in the international oil market,” said Petron Corp. Last week, oil companies raised the per liter prices of gasoline, diesel and kerosene by P0.35, P0.60, and P0.45, respectively. — Victor V. Saulon
