McKusick History

John McKusick started McKusick Petroleum in Dover-Foxcroft on October 1, 1972. With a single truck he delivered propane and sold gasoline and motor oil from his store. In 1982, McKusick began offering fuel oil, and the business grew from there.

In 1984, McKusick bought Harmon's Texaco (now Harmon's Heating Oil) in Milo, which offered gasoline, auto repair, heating oil, and LP Gas. In 1998, Johnson's Burner Service in Harmony joined the company, substantially increasing our service range.


Today, Mckusick Petroleum has grown to forty full and part-time employees. We offer heating oil, propane delivery, burner repair and home heating equipment sales as well as offering gasoline, motor oil, and light auto repair at our service stations. We serve roughly 10,000 regular customers who have come to appreciate the friendly, local service we offer.
