Uno-X is a chain of unmanned fuel stations throughout Norway and Denmark. It is operated as the low-cost section of YX Energi. The chain was originally created as a low cost chain in Denmark in the late 1950s. The rights to use the name in Sweden were sold to Britain's Burmah Oil. In 1991 Norsk Hydro acquired the 330 outlets of the Danish operation and five years later it bought the Swedish Uno-X chain from Burmah.
