A BP on Superior Ave and a BP on Chester Ave are at $3.99 if you pay with cash or $4.09 with a credit card.

Saturday’s AAA national gas average is $3.922 with Ohio’s average slightly lower at $3.768.

One week ago, Ohio’s average was $3.333 and $3.264 one month ago.

Gas prices are expected to continue rising.

“Consumers should prepare in case gasoline prices rise even further,” Jim Garrity, director of public affairs AAA East Central said in a statement Thursday. “At this point, all eyes are on crude oil, which accounts for 50 to 60 cents of each dollar you spend at the pump. But we’re right around the corner from demand increasing and the sale of summer blend gasoline, which are both trends that typically push prices higher in the spring.”

The highest recorded statewide average was on May 4, 2011 at $4.159 for regular unleaded and $4.750 for diesel.
