Top Oil
Tedcastles Oil Products Limited is an Irish petrol(TOP) company founded in 1960 which trades under the brand name "TOP". Before a rebranding in 1998, the company traded as "Tedcastle's Oil". It is a subsidiary of Tedcastles Holdings Limited.
The company operates petrol stations mainly outside Dublin.
From 1998-2004 the company operated a convience store chain on a franchise basis with ADM Londis. These stores were known as "Londis Topshop". This allowed forecourts to become franchisees of both Londis and TOP at once. However it also had high street stores in competition with ADM Londis itself. In 2004, the stores were acquired by ADM and rebranded to simply Londis.
