The statewide average for regular gasoline in South Dakota has dropped a penny over the last five days to $3.55 a gallon, AAA says.
Today’s national average price at the pump is $3.67 per gallon, three cents more than last week, 14 cents more than one month ago and 15 cents more than one year ago.
“Once again, we’re pointing to a decrease in supply as the culprit,” Marilyn Buskohl, spokeswoman for AAA South Dakota, said. “Refineries are required to start producing summer-blend gasoline by May 1, and in anticipation of this, they often go offline for scheduled maintenance. This drop in supply can cause prices in certain areas to rise.”
Although inventories in the US are beginning to increase, pump prices have jumped dramatically in several states: Delaware (up 9 cents), Oregon (up 9 cents) and New Jersey (up 8 cents). Drivers in the majority of states, including South Dakota, continue to pay more today than they did one year ago.
