Susquehanna Valley gas prices rose six cents to $3.45 a gallon this week, according to AAA East Central.

On the National Front

Tuesday's national average price per gallon of gasoline is $3.26.

The price at the pump is seven cents more expensive than one month ago, but it is fractions of a penny less expensive than one week ago and remains eight cents less than the same date last year.

Price movement over the last several weeks has been a mixed bag at the state level. While pump prices in 20 states have continued to march lower, prices in 30 states and Washington, D.C. have drifted higher.

Underlying the recent volatility in state average gas prices has been the price of West Texas Intermediate (WTI) crude oil. After 15 straight weeks above $100 per barrel, WTI begins an eighth consecutive week below this threshold, even after settling higher every day last week on positive economic news. A stronger economy - both domestically and overseas - puts upward pressure on crude oil prices as more robust economies are expected to use more oil.

At the close of formal trading on the NYMEX on Monday, WTI settled at $97.34 per barrel.
