Ms Elsenhans will replace John Drosdick, current CEO and president, who will retire from the company. Ms Elsenhans has also been elected a member of the board of directors of Sunoco.

To assist in the transition, Mr Drosdick will remain as non-executive chairman of the board until December 31, 2008.

An experienced oil industry executive, Ms Elsenhans joins Sunoco most recently from Shell Downstream, a subsidiary of Royal Dutch/Shell Group, where she served since 2005 as executive vice president of global manufacturing.

Jack Ratcliffe, presiding chairperson of the governance committee at Sunoco, said: For the last year, the board of directors searched for a CEO with excellent credentials and experience to succeed Jack Drosdick. Lynn has the outstanding background in refining, marketing and chemicals to lead Sunoco’s traditional business lines, as well as champion the growth of our promising coke and logistics businesses.
