I trust nothing the current administration has propagandized.
Their numbers for exports of refined fuels give lots of explanations for US retail pricing of fuels when exports are measured in millions of barrels per day (MBD).
One in their history shows when diesel prices exceeded gasoline in the 1980’s when the msn reported it was due to excessive US demand, in reality was increase of diesel exports significant enough to be reported as there was more value in exporting diesel to decrease the available supply in the US thus driving prices up in the US.
Refined fuels will be sold where there is greater demand.
