The national average price of gasoline fell in March for the first time in a decade, down $0.15/gal. for the first M/M decline since 2003 and down nearly $0.30/gal. Y/Y, AAA reports. Since peaking at $3.79 on Feb. 27, prices have dropped 29 out of 33 days. AAA thinks April prices should remain less expensive than in recent years because oil is cheaper and refinery production is rising.
