Mobil 1 and O’Reilly Auto Parts are giving three lucky Pit Crew Challenge Sweepstakes grand prize winners the opportunity to receive pit crew training at the 5 Off 5 On pit crew school in Mooresville, N.C. Home to more than 20 NASCAR race teams, Mooresville is nicknamed "Race City, USA." Winners also will meet Tony Stewart, driver of the No. 14 Mobil 1/Bass Pro Chevy, and tour the Stewart-Haas Racing shop in Kannapolis, N.C.
