Gas Prices Rise Three Cents In Last Week

After last week's significant jump, the average price of gasoline drifted higher in the last week, rising by three cents a gallon.

The national average price of self-serve regular today is $3.497 per gallon, up nearly eight cents from $3.467 last Friday, according to AAA's Fuel Gauge Survey. That's 12 cents a gallon more than what motorists were paying a month ago.

The average price of diesel fuel today is $3.908 per gallon, up from $3.877 a week ago.

There continues to be a divide among states that refine their gasoline from North American oil and those who get fuel from refineries that use Brent crude from the Middle East, which costs more.

U.S. supplies of oil and refined gasoline remain plentiful. The U.S. Energy Information Administration reported this week that crude stockpiles in the U.S. increased by 300,000 barrels in the last week. Gasoline supplies increased even more, by 1.6 million barrels.
