Joey Logano led 92 laps to win the Royal Purple 300 from Auto Club Speedway in Fontana, Calif. Logano started on pole and led the most laps, but it was a hard-fought win.

For most of the race Logano, Brad Keselowski, Justin Allgaier, and Kyle Busch swapped the lead back and forth. At one point Keselowski and Logano swapped the lead four different times on one lap. But it was Logano who was able to pull away on a restart with 12 laps to go to take the win.

The win is Joe Gibbs Racing's eigth in a row at this race track. Most of those have come with Busch, who is now racing for is own team, Kyle Busch Motorsports.

Busch had to start the race at the back of the field for missing driver introductions, but quickly made his way to the front. He was 15th by lap 5. Busch had a chance to win the race but a mistake on the last pit stop threw that out the window. The call was for two tires, but the rear tire changer went around to change the left rear anyway. He took the tire off, then put it back on, but didn't have enough lugnuts anymore so the team then decided to go ahead and change all four. The stop took Busch from third to outside of the top 10 on the final restart. Busch rallied back though to finish eighth.

Keselowski finished third because he also had pit road issues. Keselowski was fighting up front when he stopped too close to the inside pit wall on his second pit stop. He would eventually get back to the lead, but falter on the final run of the race.

Brad Sweet, a competitor for the Rookie-of-the-Year title in the Nationwide Series drove up to a sixth place finish. Sweet drives full-time for Kasey Kahne Motorsports in the World of Outlaws Sprint Car series.

Kenny Wallace ran in the top-10 all race long and managed to finish seventh.

Danica Patrick blew an engine on lap 63 and finished 35th. She had a piece of debris puncture her radiator which drained all of the water. The engine overheated and eventually let go.

The race saw a lot of side-by-side racing. Especially on restarts. On two occasions drivers went five-wide.

There was only four cautions for a total of 17 laps. Two were for debris, and two were for spins by Sam Hornish Jr., and Blake Koch.
