Irving Oil is an international refining and marketing company with a history of long-term partnerships and relationships. Founded in 1924, Irving Oil operates Canada's largest refinery in Saint John, New Brunswick, along with more than 900 gas stations and a network of distribution terminals spanning Eastern Canada and New England. It also operates Ireland's only refinery, located in the village of Whitegate. In 2019, Irving Oil expanded its presence in Ireland by acquiring Top Oil, a leading supplier of home heating oil, petrol and diesel fuel. Irving Oil established its European operations in 2014 with an office in London, England, and tankage in Amsterdam. Customers describe Irving Oil's gas stations as clean, with friendly and courteous staff. The bathrooms are always very clean, and the stores offer a variety of products, including what is considered the best pizza by the slice in the area. Customers can sign up for Irving debit pay to save money at the pump and earn points for discounts. However, one customer reported that the 91 octane fuel did not taste right, suggesting a possible mix-up with the 89 octane fuel. Overall, Irving Oil is a reliable and customer-focused business that provides a positive experience for its customers.
