The national average is up 39.1 cents per gallon from a month ago and stands $1.43/gallon higher than a year ago, according to GasBuddy data compiled from more than 11 million weekly price reports covering over 150,000 gas stations across the country.

“Those filling their tanks last week saw another jolt at the pump, as both gasoline and diesel prices continued their multi-week rally,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “New records continued to be set on a near daily basis as the national average edges even closer to $4.50 per gallon … demand continues to edge higher and inventories of both gasoline and diesel continue to decline, temperatures warm and motorists get back outside and we near the Memorial Day weekend, the start of the summer driving season. While the increases may start to slow in the days ahead as pump prices catch up to oil, there isn’t much reason to be optimistic that we’ll see a plunge any time soon.”
