Safety-Kleen has been an official NASCAR partner since 2004, providing on-site trackside support with its NASCAR performance cleaning products, as well as oil recycling and re-refining services to more than 200 NASCAR-sanctioned races each year.

Safety-Kleen has been at NASCAR racetracks collecting used oil since 1987 and last year collected and re-refined approximately 185,000 gallons of NASCAR oil at tracks and team shops. Overall, Safety-Kleen services more than 145 professional race teams and 65 tracks across North America.

"We're proud to be an official partner of NASCAR and excited to help them continue their leadership role in protecting the environment and making auto racing green," said Eric Zimmer, executive vice president of sales and service for Safety-Kleen.

Safety-Kleen is also an "Official partner of NASCAR Green," a category of sponsors that contribute in a substantial and measurable way to the sport's goals around environmental conservation and to serving as a green demonstration platform while creating jobs. Other sponsors in this category include Coca-Cola, Coors Light and American Ethanol led by Growth Energy.
