GasBuddy's Patrick De Haan expects to see gasoline prices steadily decline from now heading into the fall months. The average national gallon of gas can even slip below $3. That's all depends on geopolitical factors, especially around Russian oil tariffs and a shift in escalation on the Ukraine War, says Patrick. He later explains that crude oil's price tag hovering around the $60 mark will add downward pressure on prices at the gas pump.
