<B>SUPERIOR, Wis. –</B> Officials from the O’Reilly Auto Parts United States Modified Touring Series (USMTS) revealed today that AMSOIL – the world leader in synthetic motor oils and lubricants – has been named the “Official Oil of the USMTS” as part of a new marketing partnership between the two automotive and motorsports icons.

“We are extremely pleased to announce AMSOIL as a new major marketing partner to our network of corporate supporters,” said O’Reilly USMTS Communications Director Jeff Nun. “Our relationship with AMSOIL is further evidence of AMSOIL’s commitment to motorsports, and helps the O’Reilly USMTS uphold our pledge to give racers and fans the most competitive and exciting racing show on dirt.”

In addition to contributing to the season-ending O’Reilly USMTS points fund, AMSOIL will also sponsor the newly-created AMSOIL Lap Leader Award. As such, AMSOIL will award $1,000 to the O’Reilly USMTS driver who leads the most “A” main laps during the rugged 2006 racing season.

“AMSOIL continues to outpace the competition,” said AMSOIL Director of Racing, Jeremy Meyer. “The USMTS showcases some of the best modified racers in the world. This relationship with the USMTS as the Official Oil bolsters the AMSOIL reputation that it is committed to America's dirt tracks, its racers and its fans.”

AMSOIL products will be available pit-side to O’Reilly USMTS drivers at several events during the 2006 season. AMSOIL is already track-tested with the Series, however, as Kelly Shryock used AMSOIL to help carry him to his seventh straight O’Reilly USMTS national championship in 2005.

In addition to its sponsorship agreement with the O’Reilly USMTS, AMSOIL also sponsors many other motorsports series, organizations and competitors, including the WORLD Dirt Racing League, AMA Motocross Championship, WPSA PowerSports Snowmobile Tour and ChampBoat (power boat) Series.
