About Us

Since 1935, Farmer’s Union Oil of Southern Valley has grown from one small service station to a full-service co-op serving thousands of customers in more than seven counties across North Dakota, South Dakota, and Minnesota.

Today, we provide agronomy services, and we have four Cenex convenience stores that offer a variety of fuels for farms, homes, and vehicles, vehicle maintenance and repair services, home goods, hardware, hot food, snacks, and groceries.
