U.S. diesel reached a fresh national-average record of $6.27 per gallon on Tuesday after first exceeding $6 on Friday, as the Iran war, disrupted Strait of Hormuz flows, attacks on energy infrastructure and refinery outages tightened fuel supplies. Gasoline was previously reported at $4.3163 per gallon, while crude rose to around $103.5 a barrel Tuesday; later readings put Brent at $108.16 and West Texas Intermediate at $103.86. The Energy Information Administration said Middle East production shut-ins reached 6.7 million barrels per day in August and global oil inventories fell by 400 million barrels this year. The Trump administration rejected fuel-export limits, instead backing higher U.S. production, LNG exports and potential Defense Production Act support for refinery capacity.
