Edward H. Wolf & Sons

What Edward H. Wolf & Sons does

Edward H. Wolf & Sons, Inc. is a privately held, fourth-generation family-owned fuel and lubricant distributor headquartered in Slinger, Wisconsin. Founded in 1941 as a Standard Oil agency, the company today distributes gasoline, diesel, high-octane race fuel (100–116 octane), diesel exhaust fluid (DEF), and a multi-brand lubricant portfolio (Chevron/DELO/Havoline, Petro-Canada/DURON, Kendall, Lubriplate, Mobil, FUCHS, AeroShell) to commercial, industrial, municipal, agricultural, fleet, motorsports, and retail fuel station customers across Wisconsin and the Upper Peninsula of Michigan through six locations (Slinger, Green Bay, Verona, Waukesha, Neenah, Oconomowoc).

Distribution is built around an owned delivery fleet — MA Wolf Trucking, which includes 40-ton Mack Granite transports — providing wet fueling, on-site delivery, cardlock fueling, and a 24/7 emergency service line. The company layers services onto commodity supply: free tank monitoring integrated with dispatch, equipment sales and installation (bulk tanks, DEF dispensing, automated lubrication systems), and laboratory fluid and fuel analysis delivered through partnerships with Chevron, Polaris Laboratories, and Power Service. Cardlock fuel stations and retail supply agreements under branded programs (BP, Amoco, Citgo) extend the channel.

The business is monetized primarily on per-gallon transaction fees for fuels and per-unit pricing for packaged lubricants via an e-commerce storefront, with quote-based bulk contracts for commercial accounts. A PetroDataSync-powered customer portal with native iOS and Android apps, SSO (Microsoft, Google, Apple), and Stripe/PayPal payment processing supports account management. AI capability is limited to third-party tooling — most notably Samsara for AI-driven fleet safety and dashcam analytics. Growth has been delivered mainly through acquisition (Tilot Oil 2003, Hopson Oil 2013, Zurbuchen Oil 2022, Wolf Brothers Fuel and Air Plus LLC division 2023, Levnhagen Corporation 2025) rather than external funding, with no institutional investors or parent company disclosed.
