“We’ve now seen the national average price of gasoline rising for four straight weeks, which isn’t uncommon for this time of year. What is uncommon is the number of attacks on Russian oil refiners; attacks which could have ripple effects worldwide if they continue,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “With oil prices now under more pressure and attacks potentially increasing on Russian refiners, we could be in for a few more weeks of rising prices. Significant as well is the fact that Americans are now seeing inflation again at the pump with prices higher than they were a year ago.”
