In 1920 a government initiative, in conjunction with British Petroleum, saw the birth of C.O.R. - The Commonwealth Oil Refineries. Motor spirit was available and in 1934 a Benzol mixture was added to the range.In 1952 BP gained full ownership and C.O.R. entered an interesting transitional period where BP and C.O.R. were avaiable from the one oulet and even the same pump. BP was marketed as super grade and C.O.R. as standard. During 1959 C.O.R. was phased out.
