AMSOIL is the Official Oil of the Diesel Power Challenge

The Diesel Power Challenge is the creation of Diesel Power Magazine and the Primedia Truck Group.  This was the fourth year of the Diesel Power Challenge, a grueling two-day event that tests the mettle of the toughest street legal turbo diesel trucks. The event in Utah will result in 40 pages of magazine coverage later this year, along with a one hour TV program to be aired nationally.

This year eleven pickups arrived for the competition, all maxed-out turbodiesels.  All of the trucks, selected by the readers of Diesel Power Magazine, are put through rigorous testing for two days.  The tests include a 1/4 mile drag-strip run, 1/8 mile drag while pulling a 10,000 lb trailer, sled-pull for distance, chassis dynamometer pulls testing horsepower and torque and a 100 mile drive to see which turbodiesel has the best fuel economy on the road. 

The growing popularity of diesel vehicles in the United States makes events like the Diesel Power Challenge an unrivaled opportunity to put AMSOIL products to the test in the most severe operating conditions.
