Al Warren Oil

Family-owned petroleum marketer since 1948 supplying fuel and lubricants, tank services, fleet fuel-management systems and 24-hour emergency fueling across Northern Illinois and nearby states.

Al Warren Oil is a third-generation, family-owned petroleum marketing company founded in 1948, when Al Warren started the business with a single truck delivering home heating oil around Chicago. It now supplies diesel, gasoline, biodiesel, DEF and lubricants in bulk to commercial, industrial, municipal, agricultural, construction, marine, locomotive and transportation customers across Northern Illinois, Northwest Indiana, Southern Wisconsin and nearby markets.

The company's technical work spans several disciplines. It installs permanent and temporary fuel tanks and carries out tank cleaning, provides fleet fuel-management systems and on-site fueling equipment alongside fleet-maintenance supplies, and operates around-the-clock emergency fueling and spill response. Fuel-handling and service operations run year-round.

Delivery of bulk petroleum products remains the core of the business, supported by close customer relationships and an emphasis on dependable, responsive service. Operations are continuous, with customer assistance available at all hours.
