Gas prices are on the rise. The national average for regular unleaded adds a penny to $3.10; here in Oregon, our average jumps up to 4¢ to $3.21. Triple-A's Marie Dodds says that as long as crude oil remains above $92.00 a barrel, gas prices will remain high. Diesel increased a nickel a gallon to $3.47 in Oregon.  The average cost for a gallon of gas in Bend this week is $3.17.
