[OUR STORY]

More than oil & gas,
we are family.

We know that fuel isn’t just fuel. It’s heat on a cold winter morning. It’s a farm running at sunrise. It’s a business staying open, a family staying comfortable, and a job getting done on time. That’s why we treat every delivery, service call, and installation with care, safety, and respect.

For more than 60 years, Nelson’s Oil & Gas has been a trusted partner for families, ranchers, and businesses across Southwest South Dakota. We’re a family-owned company built on simple values—honesty, safety, and dependable service—delivering the fuel, heating, cooling, and support our communities rely on every day.
