Sioux Falls Gas Prices Explode Overnight By .30¢ Per Gallon

Drivers in Sioux Falls are getting another unpleasant surprise at the gas pump this week, with prices taking another major jump overnight.

Gas prices at some Sioux Falls stations have climbed nearly 30 cents per gallon since Monday, making an already expensive trip to the pump even more painful for local drivers.

The increase comes as gasoline prices continue to surge across the country.

According to AAA, the national average for a gallon of regular unleaded gasoline reached $4.37 as of October 5, 2026.

And it's not just gasoline that is putting the squeeze on drivers. The national average for on-highway diesel fuel is now $6.38 per gallon, creating additional challenges for truck drivers, businesses and anyone who relies on diesel-powered vehicles.

For Sioux Falls drivers, the sudden overnight increases can make a noticeable difference in the cost of filling up a vehicle.

Filling up a 15-gallon tank now costs over $64.00 for a single fill-up.

With prices changing quickly, drivers may want to shop around before filling their tanks. Even a few cents per gallon can add up over multiple fill-ups.

After seeing gas prices make several dramatic moves recently, Sioux Falls drivers will likely be watching closely to see whether this latest jump continues or if some relief finally arrives at the pump.
