WASHINGTON — The average on-highway cost of a gallon of diesel increased by a penny to $2.797 for the week ending October 23, according to the Energy Information Agency of the Department of Energy.
It marked the third straight week the price has increased, albeit only 2.1 cents a gallon.
All but one region of the country showed an increase.
The lone decrease was two-tenths of a penny in the Central Atlantic states.
The largest increases were in the Rocky Mountain region at 3.1 cents a gallon and the Midwest at 2.2 cents a gallon.
On the down side, the price is 31.9 cents a gallon higher than the same week in 2016.
