In January 2026, RelaDyne acquired Dennis Oil Company, a blender and distributor of commercial and industrial lubricants serving customers across Missouri, Kansas, Oklahoma, and Arkansas.
Dennis Oil Company, established in 1940, is headquartered in Springfield, Missouri. Over the past 80 years, Dennis Oil Company has grown from a regional supplier of case goods for service stations into a trusted provider of bulk lubricant solutions for trucking, manufacturing, excavation, and quarrying industries. Dennis Oil Company offers a comprehensive line of engine oils, diesel exhaust fluid, hydraulic oils, gear oils, and grease to the manufacturing, trucking, automotive, mining, railroad, and agricultural industries.
“We are thrilled to welcome Dennis Oil Company to the RelaDyne family,” said Eric Royse, Chief Executive Officer of RelaDyne. “Dennis Oil Company’s service footprint and product breadth perfectly complements our existing operations in the Midwest, improving our density in key regional markets. By combining Dennis Oil Company’s exceptional customer service, existing relationships, product expertise, and an enviable reputation in the commercial and industrial sectors built over 80+ years, we are certain that RelaDyne and Dennis Oil Company, together, will provide even greater reliability to the market.”
RelaDyne’s dominant presence in the automotive, commercial, and industrial segments creates an amazing opportunity to expand our product offering and service capability in our current footprint. Joining forces with the RelaDyne team propels our capacity to grow with our longstanding, loyal customers, while also expanding our high level of service to new customers we could not previously reach. I am extremely proud of what we’ve been able to accomplish at Dennis Oil Company and cannot wait to execute on the opportunities that this combination brings for our associates and our customers.
Jeff Dennis, President of Dennis Oil Company
