“For the first time in ten weeks the national average has risen, and certainly not just a small increase but a very noticeable rise on the heels of attacks on Saudi Arabia that knocked out 5% of daily oil production,” said Patrick DeHaan, head of petroleum analysis for GasBuddy.

“While the worst is now behind us, there remain some concerns that could cause oil prices to rise further, including a fairly optimistic timeline from the Saudis that may prove challenging to meet. Should timelines be extended, motorists may see additional slight increases. Moving forward, expect a week of relative calm after the attacks, but as hurricane season continues to also be active, there are risks that may continue to push gas prices slightly higher in coming weeks before we get clear of such issues.”
