About QUAKER STATE

Quaker State is an American brand of motor oil made by SOPUS Products, a division of Royal Dutch Shell (RD), and the successor of the Pennzoil-Quaker State Company. Quaker State gets its name from the nickname for Pennsylvania, the state founded by William Penn, a Quaker. The company was the former sponsor of the IndyCar race Quaker State 500 (now known as the Pocono IndyCar 400) in 1988, and the current sponsor of the NASCAR Sprint Cup Series race Quaker State 400 at Kentucky Speedway.
