Gas stations are in the process of switching over to a more expensive summer blend and that's one reason why the cost of filling up has been increasing. The statewide average is now $3.61.  Since late last month that's a jump of about 5 cents a gallon.

This is a part of something called a seasonal gasoline transition. In the spring more refineries tend to go through maintenance. Some start limiting capacity while others completely shut down.  Whenever that happens we can usually count on pump prices to start heading up.
