nowing Marran is up all night, every night, keeping you safe and secure. For 120 years, five generations of Marrans have embraced the latest technology and worked tirelessly to perfect the finest customer service on Long Island. My great-great-grandfather, William R. Marran, founded Marran Oil in 1891. He delivered kerosene for cooking and space heaters to his neighbors and friends by horse-drawn cart. He passed his philosophy down to his son: “Service your customers well and treat them as your neighbors and friends." My great-grandfather, Francis Marran, modernized the delivery system by switching from horse-drawn cart to motorized tank trucks, which could deliver oil more efficiently to a larger area. In the early 1930s, he constructed a million gallon oil terminal on the Patchogue River, which received barges from New York harbor. He worked with Standard Oil, supplying their oil to other companies and to his customers throughout Suffolk County. Under his leadership, Marran was the first oil company to provide automatic delivery to its customers. He began to sell oil as an alternative to wood or coal heating systems. He called it “automatic heat,” because it eliminated the necessity to feed the fire. He believed that a company should invest in its infrastructure and equipment to provide better services and products to its customers. His philosophy was “Innovate and provide your customers with the best products.”
In 1935, Francis Marran’s death left his widow alone with the challenge of raising four young children during the Great Depression. Marcelle D. Marran said that it was the community of neighbors, friends, employees, customers, and priest that convinced her to run the business to support her family. As a schoolteacher, she had often told her students, “There’s no such word as ‘can’t’” to correct their grammar. As one of Long Island’s first businesswomen, that phrase became her motto. She successfully ran and grew the company before her son came to work with her. She reminded my grandfather that their loyal customers had helped her keep the business going through the death of his father and the oil rationing during World War II. She told everyone she knew that, “When it comes to your customers, there’s no such word as ‘can’t.’”
In 1948, William R. Marran II took over the family business from his mother. He had been a Navy Officer in World War II and was trained in radio communications. He erected a radio tower on the highest hill in Suffolk County and equipped all of Marran’s oil and service trucks with two-way radios. He used the technology to introduce 24-hour radio-dispatched emergency services. He experienced the huge post-war expansion of home ownership on Long Island and equipped many new homes with oil-fired heating systems. He also converted many existing homes from coal to oil. In the 1970s, the Middle East oil embargo caused oil prices to soar. My grandfather and his brother, John Marran, collaborated to create the first low mass, computer-controlled heating system. As the most efficient system of its time, it allowed customers to burn less oil, saving them money and reducing their carbon footprint in a time of high oil prices. With continuing design improvements, the System 2000 is still the most efficient oil-fired heating system on the market. In June of 1989, my grandfather introduced the first fixed-priced oil program to Long Island. The program allowed customers to agree to a specific price at the beginning of winter. My grandfather would purchase the oil in advance at the agreed price and then distribute it throughout the year. In December of 1989, oil prices spiked when Iraq invaded Kuwait. The fixed price program was an instant success. Our customers were protected from the price spike and therefore saved a significant amount of money. William Marran retired in 1995. His motto was, “Provide the best quality service, help your customers save energy with the best technology, and always be available to them.”
In 1982, my father started working at the company with his father, grandmother, brother, and sister. He has kept to our family’s tradition of personalized service—like my grandfather, Dad puts his telephone number in our All Risk Service Contract. In addition, building on Marran’s past, he has added Alarm and Air Conditioning to the services we provide our customers. I have learned a lot about this company and my family through writing this historical narrative. As the fifth generation Marran, I am very proud to have added to the history of this company. Everyone at Marran Oil has always been so nice to me over the many years of visiting my dad at the office and then eventually working on a variety of projects with him during the summers. I am currently a senior in high school and will start college in the fall. However, I look forward to being more involved in the family business in the future.
