What Mansfield Service Partners does

Mansfield Service Partners (MSP) is a Houston-based fuel, lubricant, and environmental services distributor operating as a subsidiary of Mansfield Energy Corp. Founded in 1932, the company delivers bulk on-road and off-road diesel, gasoline, renewable fuels, biodiesel, and Diesel Exhaust Fluid (DEF) through a 24-hour fleet serving Texas, the Gulf Coast, Minnesota, Ohio, Colorado, and broader North America. It distributes industrial lubricants, hydraulic fluids, gear oils, greases, and specialty products under the Shell, Valvoline, Summit Specialty, and proprietary Emerald Lubes brands, and operates a wholly-owned marine fuel subsidiary (OMS Marine) serving the Houston Ship Channel and Gulf Coast. Complementary services include SMARTank telemetric tank monitoring, oil and fuel sampling/analysis, tank installation and maintenance, mobile on-site fueling, fleet cards, fixed-price fuel programs, and HAZMAT/environmental services through its Select Environmental division.

The company's technology stack centers on the SMARTank telemetric monitoring program — installed on customer storage tanks — which captures fuel use, replenishment history, and consumption analytics, and the PetroNet web portal, which handles customer ordering, account management, and invoice access. There is no evidence of proprietary AI/ML systems; technology serves primarily as an operational and customer-experience layer rather than a differentiated intelligence layer.

MSP generates revenue primarily through transaction-based pricing on delivered fuel and lubricants, supplemented by professional-services fees for environmental, equipment, and oil-analysis work. Pricing is quote-based and not publicly disclosed. The company runs an enterprise field-sales GTM, with field representatives providing on-site consultation and customized fuel/lubricant solutions to mid-market and enterprise customers. Customer segments include transportation and trucking, construction, oil and gas, industrial and manufacturing, marine, petrochemicals and refining, and automotive. The company employs 101-250 people and operates approximately 150,000 square feet of storage capacity across its Houston, Dallas, Tyler, Loretto (MN), Sidney (OH), and Aurora (CO) facilities.
