Kyle Busch overhauled Jimmie Johnson to reclaim the top spot in the AAA 400 at Dover International Speedway with 44 laps remaining and Denny Hamlin has taken second from the No. 48. Fuel strategy might be the factor, however, as ESPN played audio of Johnson's crew chief Chad Knaus telling his driver that he could either start saving fuel now and try to stretch their fuel tank to the end of the race or run hard and have to pit late if a caution doesn't come out.
Busch's team, meanwhile, can't make it on gas and thus he has kept the throttle down. Brad Keselowski can make the race on fuel and runs fourth, as can fifth-place Jeff Gordon. Mark Martin, Clint Bowyer, Carl Edwards, Martin Truex Jr., and Joey Logano round out the top-10.
Kasey Kahne also could have made it on fuel and was primed to potentially win the race, but his team left a front tire loose on his pit stop. A loose wheel at Dover can vibrate the fillings out of a man's teeth - even when he has none to begin with - and Kahne had to hit pit road. He then had to pit again because the crew did not get all the lug nuts tight.
