UNITED STATES -- The national average gas price is up four cents over the past two weeks. That's according to the latest Lundberg survey released this weekend, and that's the lowest increase since early January. The survey found the national average is around $3.97.

Analysts said supply is up and crude prices are down, which both slow down increasing gas prices.

AAA reports the average price in New York State held steady all weekend at $4.14. Massachusetts drivers are paying about $3.90 a gallon.
