US average gasoline prices have risen for the fourth straight week, up 8.7 cents/gal to $3.26/gal, according to GasBuddy.

• Gasoline prices are up 16.7 cents/gal on the month but are 11.6 cents/gal lower than a year ago.
• “One of the most critical elements to how much gas prices will climb is how quickly and effectively refiners can finish their pre-summer maintenance, start producing EPA-mandated summer gasoline, and build up supply of it before Memorial Day,” Patrick De Haan, head of petroleum analysis at GasBuddy said.
• US retail gasoline demand saw an increase of 0.7% for the week ending Feb. 18 at around 8.381m b/d.
• Average diesel prices rose 10 cents/gal on the week to $4.09/gal, down 38 cents/gal on the year.
