Amsoil Inc. of Superior announced a changing of the guard in management Tuesday, as its 91-year-old founder, Al Amatuzio, steps down from his post as president and CEO of the company.

AMSOIL is the first company to pioneer synthetic oils in other applications outside of aircraft. Despite global scaling, AMSOIL still has only one factory.

This year's AMSOIL/STREET RODDER Road Tour Shadow Rods XL27 roadster pickup is the latest in a line of successful projects.
