Sebastian Vettel will revert to a normal free practice preparation for the remaining four grands prix of the 2009 season.

The German had been limiting his mileage at recent races due to his diminishing supply of fragile Renault engines.

But after a bad Italian grand prix, where the Red Bull driver's points deficit to leader Jenson Button dropped to a near-insurmountable 26 points, the team will instead throw caution to the wind because there little to lose.

"It is no longer going to help us if we drive defensively," the energy drink company's racing advisor Helmut Marko is quoted as saying by Germany's Auto Motor und Sport.

Team owner Dietrich Mateschitz said after Monza that the championship dream is now over, but Vettel told F1's official website that he will push to win the last four races of the season.

"I will fight to the last breath and minute," said the 22-year-old.
