MOSES LAKE — There was a slight decrease in gas prices across the nation, including in Washington and Grant County, according to AAA. The Adams County average remains the same as last week. 

“The national average price of gasoline slipped slightly over the last week, falling alongside oil, which dropped more than $2 per barrel,” said Patrick De Haan, head of petroleum analysis at GasBuddy. 

In Grant County, fuel costs an average of $4.36 per gallon, or a three-cent decrease from last week, according to AAA. Fuel prices this week are lower than the average one month ago at $4.42. It’s also the lowest the county has seen since June 16, when fuel prices were $4.34.  

In Adams County, fuel prices remained the same for the second week in a row at $4.34, according to AAA. Fuel prices, as of a month ago, were also sitting at the same price.  

Both Grant and Adams counties remain in the middle of the pack for gas prices in the state, according to AAA.  

San Juan County is the most expensive in the state at $5.44, a one-cent decrease from last week, according to AAA. Asotin County remained the cheapest at $3.74, which is also a one-cent increase from last week. 

Washington state’s average regular grade fuel prices also saw a slight decline this week, of one cent, bringing the average to $4.39. This is four cents cheaper than the prices found a month ago at $4.43. However, prices are higher than those of a year ago, when the average was $4.26. 

Washington remains the third most expensive state to purchase fuel in, behind only California at $4.50 and Hawaii at $4.46. 

Washington is catching up to both Hawaii and California, however. A year ago, California and Hawaii were both sitting at an average of $4.68. Since then, prices in both states have seen a slight decrease, compared with an increase in costs in Washington.  

The national average also saw a one-cent decrease this week, bringing the average to $3.14. This is eight cents cheaper than prices found a month ago at $3.22 and $0.36 cheaper than those found a year ago when the average was $3.50. 

“Pump prices have dipped to match the summer of 2021, the last time seasonal gas prices were this low,” said a statement from AAA.
