In Memory of John Ruth:

The story of Motor Oil Supply is the story of John Ruth. Fueled by his lifelong passion for cars and racing, John worked in the local automotive industry and on the NHRA racing circuit for many years before starting Motor Oil Supply in 1980.   Motor Oil Supply started with one employee and a small warehouse and has grown into one of the largest automotive lubricant distributors in Washington.

John died in April of 2008.  We miss him everyday.   His legacy remains, however, in the day-to-day operations of Motor Oil Supply and the many long-term employees who strive to carry on his vision. 

Motor Oil Supply is a proud supporter of Habitat for Humanity. For more information on the mission of Habitat for Humanity, please click here.
