(CNN) -- The national average price for a gallon of regular unleaded gasoline rose to a record high of $3.33, up one and five-tenths of a cent from the previous day's record-setting price of $3.32, AAA reported Monday.

A report out Sunday by Publisher Trilby Lundberg found that gas prices jumped more than 5 cents in the past two weeks, reaching $3.32 per gallon for the first time.

The latest Lundberg Survey, carried out April 4, tallied prices at about 5,000 gas stations for the past two weeks.

Lundberg blamed the increased prices on higher crude oil and ethanol prices at a time of weak gasoline demand. The government has mandated retailers to sell a higher percentage of ethanol, and Lundberg said she does not expect the prices of crude oil and ethanol to go down any time soon.

Also, while demand for gasoline has increased during the longer days of spring, Lundberg said drivers are using less gasoline this year compared to the same time last year.

"This is a key reason why I expect prices to jump from here," Lundberg said.

At $3.03, average prices in Newark, New Jersey, were the nation's lowest. Drivers in San Francisco, California, where the average price was $3.72, paid the most.
