(Portland, OR) -- Gas price increases are smaller this week due to a slight dip in demand, but prices are still setting records. The Triple-A reports the national average increased two cents to $4.26 a gallon. Oregon's average added a nickel bringing the state's average to $5.21. Crude prices have exceeded $116 dollars a barrel, driven by fears of further global supply restrictions with the European Union reducing the amount of gas it'll buy from Russia. Oregon's average price for diesel increased four cents to $5.72, which is also a new record high.
