Gas Prices on the Rise

Gas prices are on the rise.

The national average is up 15-cents in the last week to 3-73.  Oregon and Washington's average is up six cents to 3-63 which is still below the national average. 

Market speculation is seen as a major reason behind the price increases. 

Also, refineries are starting to produce more expensive blends of summer fuel, but those price increases normally happen toward spring, diesel increased about a nickel over the last week to 4-10 a gallon as well.
