Through his Tweets, he directly submitted questions to Energy Minister Arak Chonlatanon.
"Oil prices are jacked up, but why marketing margins are increased as well?" he asked. "Despite higher oil prices, does it mean a hike in (oil retailers') expenses and hence the margin?"
He said that the marketing margin of octane-95 petrol product was raised from Bt4.8399 per litre on January 1 to Bt5.5769 on April 11. That of octane-91 went up from Bt1.1269 to Bt2.3779; gasohol 95 from Bt0.1657 to Bt1.7967; gasohol 91 from Bt0.3513 to Bt2.0285; and gasohol E20 from Bt1.5646 to Bt3.6203.
He asked the minister to clarify why the marketing margin is raised hugely within four months.
"I want all followers to learn that in the past four months, you pay higher not only for the Oil Fund but also to oil retailers," he said.
