Dillon announced in August 2012 that he would continue to drive full-time in the Nationwide Series for 2013, with Advocare as the primary sponsor for the full season, along with running seven Sprint Cup Series races that year, including the 2013 Daytona 500, where he qualified 8th, but crashed late in the race, relegating him to a 31st-place finish. In January 2013 it was announced that some of Dillon's Sprint Cup races that season would be in Phoenix Racing's No. 51 Chevrolet.
