PHILADELPHIA, April 16, 2004—Sunoco, Inc.'s Transportation group recently announced the recipients of their 2003 Tank Truck Carrier of the Year Awards:

The selections are based on a core carrier's safety and service performance to Sunoco's customers throughout the year. The criteria for selecting our winners are outstanding on-time delivery, on-time loading, spill and accident performance and load acceptance.
