The AAA national average gas price edged up 0.4 cents to $3.171 last week. This is up 4.4 cents from a month ago but -48.9 cents lower than a year ago.

• An increase in demand – as the weather gets nicer and more people get out and about – is pushing prices up slightly. But at $3.17, the national average remains well below what drivers were paying this time last year. That’s because the price of crude oil is on the lower side at $62 a barrel compared to $82 a barrel one year ago.
