The Al Warren Oil Company was established in 1948. In the beginning, Al started with one truck and delivered for Warren Oil and other oil companies in the Chicagoland area. No matter how cold it was or how much snow was on the ground, Al always found a way to make the delivery. Hence our slogan, "Prompt-Dependable-Service". The majority of Warren Oil's home heating customers were on a keep-fill basis; however, there were also call-in and emergency deliveries. When Al made home deliveries, the customer would usually call their neighbors to see if they needed oil as well. Consequently, Al would service most of the neighborhood on one trip. In those days, the oilman was as common a sight and dependable as the milkman. It wasn't unusual for Al's customers to have breakfast waiting for him when he arrived to make deliveries.

In 1970, after two decades of growth, Al expanded to become a licensed jobber, supplying diesel fuel, gasoline and heating oil all over Chicago. Working hand-in-hand with his father, Tom Warren did everything from working on the trucks to driving them. As their volume rose, Tom persuaded his conservative-minded father to expand the fleet. Al realized that heating oil, his bellweather product for 26 years, was in rapid decline. With his son's encouragement, Al concentrated on transport hauling and saw the potential it offered. Subsequently, they started a transportation company, Altom, a combination of both of their names. In 1980, Altom had already grown to 15 tractors, 20 trailers and 6 straight trucks. Sadly, in 1985, Al passed away leaving the company to Tom. Under Tom's direction, the company grew even larger. Altom Transport became the dedicated carrier for Warren Oil and many other companies. By this time, Warren Oil became a familiar name in the Chicago petroleum industry. In addition to marketing heating oil, which is long past it's heyday but still in demand, the company is a major diesel and gasoline distributor licensed in Illinois and Indiana. Our special services include on-site fueling to large trucking companies, commercial contractors and marine vessels. Al Warren Oil is a licensed and Coast Guard approved supplier.

Today Warren Oil is still growing, concentrating on transport deliveries and spot-fueling, keeping to our motto of prompt dependable service with no delivery too small or too large. We are Coast Guard approved and make deliveries in quantities from 50 to 100,000 gallons. We are one of the few companies that the Chicago Park District allows to fuel cruise ships and freight liners.

Altom Transport is still Warren Oil's dedicated carrier, which services several hundred satisfied customers. Altom has authority in 48 states and Canada to haul petroleum and chemical products. Their fleet consists of 95 tractors, over 300 tank trailers, and 18 fueling straight trucks. Altom is approved by the United States Coast Guard to deliver diesel and motor oils.
