Gas prices in Washington were 16.0 cents per gallon lower than a month earlier and 7.6 cents per gallon lower than a year ago.

The national average price of gasoline fell 6.2 cents per gallon in the week, averaging $2.67. The national average was down 19.3 cents per gallon from a month ago and 22.2 cents lower than a year ago.
  
Over the past decade, the average price in Washington on June 17 has been above $3.32 per gallon five years and below it in five years.  
  
“For the sixth straight week, gasoline prices have declined nationally, a feat not often seen heading into the prime of summer driving season,” said Patrick DeHaan, head of petroleum analysis for GasBuddy. “Stations continued to pass along the lower replacement cost as oil prices remain under considerable selling pressure, even after last week’s attack on two oil tankers which caused not much more than the oil market to blink. We’re highly likely to see the national average decline for its seventh straight week barring any curve balls.”
