Gas, diesel keep up record run
Fuel prices remain at record levels, according to daily gas price survey.
NEW YORK (CNNMoney.com) -- Prices at the pump kept up their record-setting run overnight, a nationwide survey of gas station credit card swipes showed Thursday.
Regular unleaded remained at its record high price of $4.114 a gallon, according to a daily survey from motorist advocacy group AAA.
In the past year, gas prices have risen 35%. High fuel prices have caused Americans to limit vacation travel and cut back on driving.
Record high fuel prices have also been driving up the price of goods, adding to the pain felt by consumers. Retail prices jumped 5% on an annual basis in June, the largest rise since 1991 when fuel prices surged due to the first Gulf War.
Meanwhile the average price of diesel fuel, which is used to power most trucks and commercial vehicles, climbed six-tenths of a cent to a record $4.845 a gallon, according to AAA.
That's 64% higher than last year when diesel was cheaper than gas.
Gas prices are most expensive in Alaska, where prices average $$4.627 a gallon. California is the second most expensive state for gas, with drivers paying $4.494 on average.
South Carolina is the state with the cheapest prices for regular unleaded. Prices average $3.909 a gallon there.
Hawaii has the highest diesel prices at $5.405 a gallon, while diesel is cheapest in Montana at $4.639.
