At least two oil companies imposed modest fuel price increases on Tuesday morning, the fourth price adjustment in the current month.
In separate advisories issued on Monday evening, Pilipinas Shell and Petron Philippines both said that they would be raising the price of diesel by 25 centavos per liter and kerosene by 15 centavos per liter.
The prices of their other products such as gasoline were retained.
Other oil firms have yet to announce their price adjustments as of press time.
On February 18 to 19, oil firms raised the prices of their gasoline products by P1 per liter, 40 centavos per liter for diesel, and 25 centavos per liter for kerosene.
Phoenix Petroleum said that the price adjustments made last week reflect the movements in the prices of refined petroleum products on the world market.
But on February 11, oil firms cut their prices across the board at the pump, by 50 centavos per liter for gasoline , kerosene by 25 centavos per liter, and diesel by 20 centavos per liter.
