Gas prices rose by about 12 cents in the past week to an average of $1.65 a gallon across Colorado.
Gasbuddy.com reports prices in Colorado had fallen since August when the average hit $2.86 a gallon. But this past week that changed.
Industry experts say the price spike is due to the switch to more expensive summer gas blends. The good news is the statewide average is still below the national average – and far below what it’s been at this time of year during the five previous years.
