Zahl-Petroleum Maintenance Co

Zahl-Petroleum Maintenance Co operates from 3101 Spring St N.E. in Minneapolis, serving fueling operations across the Upper Midwest. The company holds a 4.3-star rating from 12 reviewer comments, with availability Monday through Thursday from 7 AM to 5 PM and Friday from 7 AM to 4:30 PM. As a division of Dan Larson Enterprises, Inc., this petroleum-focused business traces its roots to 1952 and carries three generations of industry experience. The company provides sales, installation, maintenance, and compliance support for petroleum systems, backed by 24/7 certified emergency service.

What distinguishes Zahl-PMC is its network of industry affiliations and specialized capabilities. The company maintains active membership in the Petroleum Equipment Institute, connects through a Gold Sponsorship with Fueling Minnesota, and holds affiliation with the American Petroleum Institute. Their service menu spans parts and equipment supply, environmental and compliance testing, tank cleaning, complete system installation, and ongoing repairs. These partnerships provide access to evolving industry standards and technical resources that support both commercial and industrial fueling operations.

Reviewer feedback highlights specific service encounters. Keith Kieffer described Greg, a technician, who identified multiple errors in a Veeder Root system, explained repair options, and resolved all issues during a single visit. Other reviewers praised the team for friendly service and strong sales support. However, two negative reviews cite customer service concerns: one reviewer reported being turned away after arriving minutes before closing time, while another described an incident involving a company vehicle. These mixed experiences suggest prospective clients should clarify service expectations and scheduling details upfront.
