“Oil prices have cooled back off after Saudi Arabia brought a significant portion of oil production and processing back online, helping the national average to begin moving lower again, but don’t tell California- who saw a massive spike of nearly 25 cents per gallon in the last week, fueled by refining issues there,” said Patrick DeHaan, head of petroleum analysis for GasBuddy.

“While most of the country will likely see prices tip-toe lower as oil prices have moved lower, California will see prices move higher in the week ahead, with increases also possible in those areas that receive their gasoline from California- including Las Vegas. Prices in most of California were slightly higher earlier this year, but if they all rise by an additional 10-15 cents they may rival the highest level since 2014. Prices there will eventually start following the national average lower, but it may be several weeks before it becomes noticeable.”
