CHARLOTTE, N.C. -- Mobil 1 will remain the "Official Motor Oil of NASCAR" through 2017 under a contract extension with parent company ExxonMobil. Mobil 1 is entering its 11th year as an official NASCAR partner. It will now be a contingency partner across all NASCAR national and touring series, the presenting sponsor of the Mobil 1 Driver of the Race Award, and the presenting sponsor of the NASCAR Canadian Tire Series. Mobil 1 motor oil is used by more than half of the teams in NASCAR's three national series, and the brand also sponsors three-time Cup champion Tony Stewart. The new deal takes ExxonMobil digital with the launch of the "NASCAR Automotive Technology Center Engineered by Mobil 1." The technology-driven content will be on NASCAR.com.
