“The national average rose slightly over the last week due to continued refinery challenges in the western U.S. that have pulled gas prices up considerably in some states, while some 1 in 5 states have seen average gasoline prices decline in the last week,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “With the transition back to cheaper winter gasoline now upon us in nearly every state, we should see prices eventually cooling back off, but if refinery issues continue to develop or linger, especially now that we’re entering maintenance season with less availably capacity online, the expected decline could certainly be offset. In addition, with oil prices now above $91 for the first time in nearly a year, there remains some offset from the rising price of oil thanks to Saudi Arabia and Russia’s war on low oil prices, now in its third month.”
