Sunoco Inc. is supplying the National Association for Stock Car Auto Racing (NASCAR) with a new high-performance fuel for the 2011 season.

The new fuel-known as Sunoco Green E15—is a 15% ethanol blend that will be used in NASCAR’s three national touring series.

“Since 2004, Sunoco has produced and delivered to NASCAR the world’s best racing fuel flawlessly in a challenging, high-stakes environment,” said Bob Owens, senior vice president of Sunoco. “We’re proud to be part of NASCAR’s dedication to conservation with Sunoco Green E15—the ultimate high-test ethanol fuel blend. In our six years as official fuel partner, Sunoco has changed with the times by helping NASCAR transition to unleaded fuel. Now we are eager to produce for the sport a high-performance ethanol blend.”

Sunoco Green E15 will be blended at Sunoco’s fuel facility in Marcus Hook, Pa. The corn-based ethanol will come, in part, from Sunoco’s new ethanol manufacturing facility in Fulton, N.Y. NASCAR team engine builders have been testing Sunoco Green E15 for several months and reports have been very positive. In fact, many have reported achieving more horsepower with Sunoco Green E15. The new fuel will be pumped directly from tankers at the track, rather than from on-site underground storage tanks. NASCAR fans will see the same great racing they have come to expect, but with a new, greener fuel.

“We know first-hand what it takes to produce high-performance, ethanol-blended fuels – almost every drop of Sunoco gasoline sold today contains ethanol,” said Cynthia Archer, vice president, marketing and development for Sunoco. “We look forward to highlighting the efforts of the whole racing community to transition to Sunoco Green E15 in time for the Daytona 500-from its manufacture all the way to the racetrack.”

As the new official fuel of NASCAR, Sunoco Green E15 will replace Sunoco 260 GTX, the 98-octane, unleaded race fuel that set the standard for performance. Starting in 2011, Sunoco Green E15 will be used by every car and truck in the NASCAR Sprint Cup Series, NASCAR Nationwide Series, and NASCAR Camping World Truck Series.
