The average price of a gallon of gasoline in Hawai'i rose slightly this week, the fourth straight weekly increase. AAA Hawaii reported today.

A gallon of regular averaged $2.35, up 1 cent a gallon from the previous week, the AAA said in its Hawaii Weekend Gas Watch.

In Honolulu, the average price was $2.28 a gallon, up 1 cent from last week. The Honolulu average was up 4 cents from a month ago, but down $1.07 from a year ago.

In Hilo, the average price was $2.45 a gallon, unchanged from a week ago. It was 1 cent lower than a month ago and $1.02 below what it was a year ago.

The average price in Wailuku of $2.49 a gallon was 1 cent lower than last week. It was 6 cents lower than a month ago and $1.36 lower than last year.

"Prices seem to have leveled out and are still below $2.50 a gallon," said Richard Velazquez, AAA Hawaii regional manager. "It remains to be seen if prices will stay somewhat flat or if the continued volatility in oil prices will impact island gas prices," he said.
