NEW YORK (CNNMoney.com) -- The nationwide average price of gasoline set another record Friday, according to the closely watched survey conducted for the motorist group AAA.

The average price of regular rose overnight to $3.28 a gallon, according to AAA's Web site. That's more than a cent higher than Thursday's record and was the fourth all-time high hit in as many days.

Regular was $2.972 on average at this time last month and $2.549 a year ago.

Drivers in states in the western part of the country shelled out the most at the pump, led by California's average of $3.62 for a gallon of gas. Alaska, Oregon, Washington, and Hawaii all had to pay over $3.40 a gallon.

New Jersey still led the nation with the cheapest gasoline, with drivers paying $3.04 a gallon on average. Wyoming and Missouri residents also pay less than $3.10 a gallon.

But when adjusted for inflation, gas prices are still below their peak. The record on that basis was $3.405 and set in March 1981, according to the Energy Information Administration.

The fuel price survey was conducted for AAA by Oil Price Information Service.
