HF Sinclair Corporation has finalized its acquisition of Industrial Oils Unlimited (IOU), a leading provider of industrial lubricants and specialty fluids. The deal officially closed on January 8, 2026, following satisfaction of all closing conditions.

Tulsa-based IOU brings a strong regional manufacturing footprint and a respected brand to HF Sinclair’s growing portfolio. “As HF Sinclair continues to broaden its presence across the U.S. market, IOU is ideally positioned to help drive the expansion of our lubricants portfolio,” the company said.

With the acquisition now complete, HF Sinclair will operate IOU’s assets while focusing on service reliability and accelerated growth across the platform.
