(The Center Square) – The U.S. price of a gallon of regular grade gasoline remained above $4 a gallon for the fifth consecutive day on Friday as escalating Middle East tensions and low domestic oil inventories put downward pressure on American fuel supplies.

The national average reached $4.11 a gallon on Friday, rebounding from a late-June low of $3.91 a gallon after a brief U.S.-Iran memorandum of understanding temporarily reopened the Persian Gulf to ship traffic.
