OIL COMPANIES are raising the prices of petroleum products this week after the minimal adjustment a week ago. Gasoline prices will rise by P0.75 per liter (/L), diesel by P0.80/L and kerosene, P0.90/L. Last week, oil companies raised the price of gasoline by only P0.10 /L, and kept unchanged the cost of diesel and kerosene. For April, per liter prices of fuel products generally rose, except for the first week when these declined between P0.10 to P0.30. The same trend was observed in March. — Victor V. Saulon
