Pumpelly Oil Company, part of the southern RelaDyne network, was one of four well-established businesses that merged to form RelaDyne in November 2010. Started in 1937 with a two-pump station in Westlake, Louisiana, Pumpelly Oil experienced continued growth and has become one of the largest oil and gas distributors in the state. The company provides its loyal customers with an array of products ranging from national brands of lubricants, specialty products, chemicals, on- and off-road fuels, and diesel exhaust fluid.  

In 1989, company founder Bob Pumpelly stepped down from daily operations to become the company’s board chair. Since then, Pumpelly Oil has been led by his son, Glenn, who for over 21 years has grown the business to employing more than 70 people with a mobile fleet of 16 trucks.  

Today, Glenn serves as RelaDyne’s Vice President of Distribution for the South and is responsible for the development and growth for all products and services as well as continuing best-in-class customer service from people you can trust and depend on.

Slidell Oil

In November 2016, RelaDyne purchased the lubricants and commercial fuel divisions of Slidell Oil Company, now part of the southern RelaDyne network. With locations in Montgomery and Demopolis, Alabama, this acquisition significantly expanded RelaDyne’s geographic density and capabilities within Alabama.

Slidell Oil began as a Shell Oil Company jobber in Louisiana in 1948 and grew to span Mississippi, Alabama, Florida and Georgia marketing retail fuel programs for Shell, Chevron, Texaco, Valero, and Liberty brands. Now, this top-tier division of Slidell Oil Company is joining the RelaDyne family.
