Premier Distributor Since 1932

MSP is a premier distributor of high-quality lubricants, fluids, fuels, and environmental services. Based in Houston, Texas, MSP was founded in 1932 by Gene O’Rourke as O’Rourke Petroleum. Since then, the company has grown from a single gas station to a nationally recognized full-service provider. In 2018, O’Rourke Petroleum was acquired by Mansfield Energy Corp, and Mansfield Service Partners was formed. Our success is the result of our continued commitment to deliver superior products and expert services to customers.
