Susquehanna Valley gas prices fell just a fraction of a penny to $3.39 a gallon this week, according to AAA East Central.

On the national front

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

Tuesday's price is two cents cheaper than one week ago and a dime less than the same date last year.

During this recent fluctuation in prices, motorists across the country have experienced a variety of changes in the price they pay at their local station. Motorists in 22 states and Washington, D.C., have seen prices rise over the last week; while those in 28 states have seen prices fall, including three states where prices have dropped by a dime or more: Indiana (10 cents), Ohio (10 cents) and Michigan (12 cents).

Gas prices increased during the second half of November primarily due to unexpected refinery problems that limited gasoline production. These problems included planned and unplanned maintenance that took longer than expected to fix. Many of these issues occurred along the U.S. Gulf Coast, which resulted in ripple effects across the eastern half of the country.

The price of West Texas Intermediate (WTI) crude oil has now settled below the $100 per barrel mark for seven straight weeks. At the close of formal trading on the NYMEX Monday, WTI settled $1.10 higher at $93.82 per barrel. Despite yesterday's increase, crude oil still remains near the multi-month low of $92.30 per barrel registered last Wednesday.
