Molo Oil History

Molo Companies can be traced back to 1870 when Bart Linehan, a native Dubuquer owned and operated a transfer company

William Molo came from New York in 1884, he was employed as a manager at A.Y. and later bought out Morrison Brothers Plumbing and Heating Division whereupon he operated his business at 472 Main St. He married Mary Linehan, Bart's younger sister. Bart and William c

ombined their businesses. Linehan & Molo started selling coal from teams of horses, it wasn't long before trucks took over. In 1926, Linehan & Molo moved to a new location on 5th St. In 1927, Molo Oil Company was formed, to sell petroleum products. In 1948, Harold Molo became President of Molo Companies. In 1951, his son, Robert joined the family business. Robert's major interests were directed toward the sand and gravel and oil businesses. Molo Oil began supplying fuel oil to home owners and gasoline to 22 area service stations in 1968, thus beginning an unprecedented growth that continues today. In 1970, Harold Molo passed away, leaving the presidency of the Molo Companies to Robert. During the decade, the Company expanded further into Iowa, Illinois and Wisconsin. The 80's was an era of growth and change for the Molo Companies, with the help of Mark Molo, Bob's son, who became Vice President. It was also the beginning of the Big 10 Mart's - convenience stores developed, and owned by Molo Oil Co. In 1998, Robert Molo passed away, Mark Molo became the President of the Molo Companies and today continues the legacy of service and growth that began over 125 years before.
