The increase in Oregon’s Gas Tax caused the State's average to increase 6¢ a gallon this week to an average of $3.13; while the national average increased only 3¢ to $3.07 a gallon. Marie Dodds at the Triple-A says this sets the stage for higher prices throughout the year. Diesel increased 3¢ a gallon in Oregon to an average of $3.40. As long as crude oil remains above $90 a barrel, gas prices will remain high. Locally, we’re finding an average in Bend being about $3.10 a gallon for the first week of 2011.
