AFTER FOUR straight weeks of price increases, oil companies will be rolling back this week the cost of petroleum products to reflect price movements in the international market. Gasoline users will enjoy the biggest price cut at P0.50 per liter (/L). Diesel products will be down by P0.15/L while kerosene by P0.35/L. For most of the retailers, the price drop is scheduled at 6:00 a.m. today, Nov. 21. Last week, oil companies raised the price of gasoline, diesel and kerosene by P0.95, P0.60 and P0.95 in one of the biggest price hikes so far this year. — Victor V. Saulon
