Effective June 2006, oil companies began distributing low sulfur diesel fuel to meet the U.S. Environmental Protection Agency's (EPA) requirement for diesel fuel for on-road motor vehicles. The new fuel's sulfur content decreased from 500 ppm to 15 ppm. This change in material composition certainly justifies reevaluating the elastomer products used in these vehicles. In addition, other EPA regulations for truck engines have resulted in an operating temperature increase of almost 50F. The combination concerned engineers at Ashtabula Rubber who investigated alternate formulas for automotive customers. "Anytime you deal with a changing environment, it's important to understand the entire application as well as the full scale of the changes taking place," says Aaron Hall, engineering manager, Ashtabula Rubber Co. "The more we know about the operating environment, the better we are able to find the right material and design for our customers."
