clean diesel

Diesel engines are cleaner than ever before, and in the next few years the diesel industry will virtually eliminate key emissions associated with on- and off-road diesel equipment. This environmental progress is the result of the new clean diesel system – combining clean diesel fuel, advanced engines and effective exhaust-control technology.

Diesel is a petroleum-based fuel with a high energy content – helping diesel go further per gallon than most other alternatives. Refiners reduced the sulfur content in diesel fuel by 97 percent.
