Gasoline prices are falling at the fastest rate since January due to cheaper crude oil costs and the resolution of some refinery issues. That’s the word from the driving club AAA, which reported the national average price of gas has dropped for 16 days in row for a total of 11 cents per gallon.

The national average price of gas was just over $2.59 per gallon Monday morning, which is the lowest average for this time of year since 2009.

Gas prices averaged $2.75 per gallon in July, which was the lowest average for the month since 2010. The national average has dropped about 14 cents per gallon since hitting a 2015 high of $2.80 on June 15.

The statewide average in Missouri for a gallon of regular no-lead gasoline was $2.406. That’s more than a penny cheaper than the day before, six cents cheaper than a week ago, 16 cents cheaper than a month ago, and about 87 cents cheaper than the average last year at this time.

The average price in St Joseph is about 13 cents more than the statewide average at $2.539.

The average across Kansas was slightly higher than $2.44/gallon.
