Overview
Maxol is the principal consumer-facing brand of the privately owned Maxol Group, an Irish oil and energy company controlled by McMullan Bros. Limited. The group traces its origins to a 1919 supply agreement between brothers William and James G. McMullan and the Anglo Mexican Oil Company, followed by the establishment of McMullan Bros. Limited in 1920. Its early business was built around petroleum distribution in Ireland and the right to continue using the Mex name after Anglo Mexican Oil Company was acquired by Shell in 1924. The modern Maxol identity emerged during a long brand consolidation. From 1972, the group began replacing the Mex, Silensol and Daisy names with Maxol; the transition across the operating companies was completed in 1981. Subsequent expansion combined acquisitions of storage, distribution and retail assets with the development of a larger branded forecourt network. Important steps included the acquisition of the Ola oil terminal at Drogheda in 1986, the purchase of 80 retail sites from Statoil and Jet in 1996, the 1997 partnership with Mace for joint convenience-store and filling-station development, and the acquisition of Connors Fuels in Northern Ireland in 2000. Estuary Fuel was acquired in 2002, adding an oil terminal, stations and further oil-product activities. Maxol’s business is broader than petrol-station retailing. Its group companies supply road fuels, bulk fuels, lubricants and home-heating oil, operate import and storage infrastructure, and provide fuel logistics. Maxol Lubricants serves automotive, industrial, marine and agricultural customers. Maxol Ltd. and Maxol Oil Ltd. run the main branded retail and bulk-fuel operations in the Republic of Ireland and Northern Ireland respectively, while Estuary Fuel and Marsh Oil Products provide terminal, import and associated oil-product capabilities. DGS Logistics distributes fuel to Maxol stations in Northern Ireland and parts of the Republic of Ireland. The group has also developed its forecourts as convenience and food-service destinations. From 2016 it began opening newer-format forecourts, initially at Mulhuddart in Dublin, with selected sites incorporating franchise relationships with Burger King, Supermac’s and Abrakebabra. In the Republic of Ireland, convenience stores increasingly adopted Maxol’s own Rosa Coffee and Maxol Deli concepts from around 2017 through an arrangement with BWG Foods. Northern Irish sites continued to use Spar-related formats and franchises, including Daily Deli, Subway and Barista Bar, under an arrangement involving Henderson Foodservice. Maxol exited some activities as its portfolio evolved. Its Maxol Direct home-heating-oil business was sold to DCC Energy in 2011, and the group discontinued production of its E85 whey-derived biofuel that year. The company subsequently focused on its integrated network of fuel retailing, convenience, food service, terminals, logistics, lubricants and selected heating-oil operations. According to the supplied reference material, Maxol had 252 locations across the island of Ireland as of August 2025. The same material reports turnover of €750 million and profit of €31.2 million for 2023, rising to turnover of €786 million and profit of €33.3 million in 2024. Between 2023 and 2025, the group acquired 14 sites and redeveloped or retrofitted 27 existing locations. In October 2025, it was reported that Maxol planned to add meal and grocery delivery, extending its forecourt proposition into local convenience delivery.
History
Maxol developed from McMullan Bros. Limited, an Irish petroleum business established by William and James G. McMullan in 1920 after they signed a supply agreement with the Anglo Mexican Oil Company in 1919. The relationship gave the McMullan business an entry into petroleum distribution and the use of the Mex identity in Ireland. When Anglo Mexican Oil Company was acquired by Shell in 1924, McMullan Bros. retained the right to use the Mex name in the Irish market. The group’s transition to Maxol began in 1972. Mex, Silensol and Daisy were legacy names associated with different parts of the business, and the company started replacing them with a unified Maxol identity. The rebranding was gradual, with all operating companies completing the change by 1981. This created a common platform for a business that was increasingly involved in retail stations, fuel distribution, storage and related oil products. Acquisitions then strengthened Maxol’s infrastructure and geographic reach. In 1986, it acquired Ola, which operated an oil terminal at Drogheda in County Louth. In 1996, Maxol purchased 80 retail sites from Statoil and Jet; the sites were being divested as a condition of the companies’ merger. The following year, Maxol entered a partnership with Mace to develop filling stations with associated convenience stores. This marked a continuing shift from fuel-only outlets toward broader roadside retail. Expansion in Northern Ireland continued with the 2000 acquisition of Connors Fuels, described in the supplied material as the region’s leading heating-oil distributor at the time. The operation became Maxol Direct (NI) Ltd. In 2002, Maxol acquired Estuary Fuel Limited, adding an oil terminal, retail locations and several oil-product activities to the group. Its operating structure later included separate companies for lubricants, home-heating oil, retail and bulk fuels, terminal operations, imports and distribution logistics. The group also rationalised its activities. In 2011, Maxol Direct’s home-heating-oil business was sold to DCC Energy, which also owned Emo. During the same year, Maxol stopped producing E85, a biofuel made from whey generated in cheese processing and intended for flex-fuel vehicles. The decision reflected a narrower focus on the activities that fit its core fuel, retail and distribution network. From 2016, Maxol invested in newer forecourt formats, beginning with a site at Mulhuddart in Dublin. These locations could incorporate food and restaurant franchises such as Burger King, Supermac’s and Abrakebabra. Around 2017, Republic of Ireland convenience stores began moving toward Maxol-owned concepts, including Rosa Coffee and Maxol Deli, under an arrangement with BWG Foods. Northern Irish stations retained Spar-related shop branding and franchises such as Daily Deli, Subway and Barista Bar through the group’s relationship with Henderson Foodservice. By August 2025, the group was reported to have 252 locations across the island of Ireland. The supplied reference material also records growth in 2023 and 2024 financial results, together with a programme of site acquisitions, redevelopments and retrofits from 2023 to 2025. In October 2025, Maxol was reported to be preparing meal and grocery delivery, indicating that the brand was continuing to broaden its role from fuel retailer to convenience and local-services platform.
