Kenworth Truck Co. has produced its latest version of a special guide to assist fleets and owner-operators in exploring ways to improve fuel economy.

The guide, “Push Less Air, Pull More Profit,” emphasizes the importance of spec’ng trucks for aerodynamics and fuel economy.

Spec’ng tips, including the use of full roof and chassis fairings, side extenders and under- hood air cleaners, are included in this four-page booklet, along with guidelines for selecting wheelbase size and fifth-wheel setting to ensure optimal trailer gap.

“Push Less Air, Pull More Profit” is available as a PDF file for electronic download and printing from the Kenworth home page at www.kenworth.com.
