LOUDON, N.H. - Jimmie Johnson gambled on fuel and made it. Ditto for points leader Matt Kenseth.

Johnson proved to be an expert fuel strategist Sunday, conserving his gas to win at New Hampshire International Speedway in a race that widened Kenseth's hold on the Winston Cup points standings.

Johnson stretched his final tank of gas for 93 laps, then carefully conserved the fuel after taking the lead in the New England 300.

"I think some strategy played into it at the end with us gambling we had enough gas to finish it," Johnson said. "After I took the lead, I had to look in my mirror the rest of the way while I conserved fuel and kept an eye on whoever was second."

The win was the second of the year for Johnson and the fifth of his two-year career.

Kenseth - also cutting it close on gas - finished third to extend his lead in the championship race to 234 points over Jeff Gordon.

"I don't know where anyone else finished, but I know we finished in front of them, so that was good," Kenseth said. "All you can do is show up every week and do the best job you can. This week I feel real fortunate to get out of here and gain points."

Ryan Newman finished fourth in a Dodge, and Robby Gordon was fifth in a Chevrolet.

Dale Earnhardt Jr. ended up sixth and maintained the third spot in the points standings.

Jeff Gordon, who easily had the best car for most of the day and led a race-high 133 laps, finished a disappointing 24th.

He didn't pit for gas when his teammate Johnson did. That meant he had to stop later, and when he made the final trip into the pits, his stop was slower than most because he decided to change all four tires instead of a gas-and-go.

FORMULA ONE: An unidentified man wandered onto the track at the British Grand Prix Sunday, disrupting the race and forcing drivers to swerve around him.

The man, wearing a kilt, was holding a sign and had placards attached to his body. He wandered onto the track during the 12th lap and was walking toward a high-speed corner as six drivers sped past. The man was on the track for about 20 seconds before being tackled by a race steward and dragged away. Police said the 56-year-old man from County Kerry, Ireland, would be charged with aggravated trespass.

Ferrari's Rubens Barrichello won the race.
