OIL COMPANIES are raising the prices of gasoline and diesel this week, on the observance of the Catholic Holy Week when many Filipinos travel to their hometown or a holiday destination. Both gasoline and diesel will record their biggest price increase so far this year at P1.15 and P1.10 per liter (/L), respectively. The price of kerosene, meanwhile, will increase by P1 per liter, the second biggest price hike for the petroleum product after the P1.15-per-liter increase on the last week of February. The price hike takes effect 6 a.m. on Tuesday, March 27. Last week, the price of gasoline was unchanged after the P0.35/L reduction on the second week of March. Diesel prices rose by P0.40/L last week, which is in contrast to the P0.55/L price cut for kerosene. — Victor V. Saulon
