Richard Childress Racing has been informed that Shell-Pennzoil will not return to the organization in 2011 according to team sources.

Shell made its debut on the No. 29 Chevrolet for the 2007 Daytona 500, which Kevin Harvick went on to win. During Shell-Pennzoil's three-year association with RCR, Harvick has qualified for the Chase for the Sprint Cup two of the three seasons. He is currently fourth in the Sprint Cup standings.

Childress said at Texas Motor Speedway this past weekend he hopes to re-sign Harvick some time this week. Certainly, driver plans must be solidified before the organization courts new sponsors for the No. 29 team.

Sources say the Shell-Pennzoil brand will move to Penske Racing next season for a multi-year deal where it will enjoy a business-to-business relationship with both Penske Automotive Group and Dodge. PAG is the second largest publicly traded retailer in the U.S. and operates 316 retail automotive franchises.

Former Cup champion Kurt Busch is expected to drive the No. 22 Shell-Pennzoil Dodge in 2011. One scenario mentioned has Brad Keselowski moving into the No. 2 Miller Dodge.
