Brad Keselowski had just enough fuel left to take the checkered flag Sunday at Dover International Speedway for his second victory in three weeks.
Keselowski won the Chase for the Sprint Cup championship opener at Chicagloland and followed that by conserving enough fuel down the stretch at Dover.
Keselowski raced to his fifth victory of the season and zipped into the points lead.
Chase driver Jeff Gordon finished second. Jimmie Johnson lost his grip on the points lead with a fourth-place finish.
Johnson and Denny Hamlin, who faded to eighth, had two of the top cars all race. They just did not have enough fuel to make a hard, clean push in the closing laps of the 400-mile race.
There are seven races left in the Chase.
