Gasoline sets another record
Nationwide average price for a gallon of regular unleaded grows nearly a penny to yet another all-time high of $3.365, AAA survey says.
NEW YORK (CNNMoney.com) -- The average price of regular gasoline jumped nearly a penny to a new record high, a survey by AAA showed Friday.
The average price of regular unleaded rose 0.8 cents to $3.365 a gallon from the $3.357 the day before, according to AAA's Web site.
Gas prices are up 19.9% from what they were last year. A month ago, the nationwide average was $3.246 a gallon.
Gasoline prices normally rise during the spring as people travel more. However, the record pump prices have also been supported by high crude prices as shrinking profit margins cause refiners to pull back on production.
Oil prices surged to a new trading high above $112 a gallon on news of an unexpected decline in inventories before falling back to $110.87 Thursday.
The rising price of diesel fuel, which is used to operate most heavy vehicles, has been driving up costs for businesses and other organizations that rely on trucks and busses.
The average price per gallon of diesel fuel rose more than 2 cents to a new record high of $4.066. Diesel averaged $3.876 a gallon last month and $2.913 a year ago.
California continues to lead the nation in pricey gas, at $3.767 a gallon. Hawaii and Alaska both maintained prices above $3.60 a gallon.
New Jersey remained the only state to see gas prices below $3.10 a gallon. Prices rose to $3.094 a gallon.
The AAA survey, updated daily, tracks prices at roughly 80,000 service stations across the country. It is conducted for the group by Oil Price Information Service.
