About Penley Oil Company
Three generations of family-owned fuel delivery excellence across Oklahoma
Our Story
Founded in 1958, Penley Oil Company has been Oklahoma's trusted partner for fuel delivery, DEF supply, and lubricants for over six decades.

As a third-generation family-owned business, we understand the importance of building lasting relationships with our customers. Our deep roots in Oklahoma mean we're invested in the success of the communities we serve—from construction companies and farms to commercial fleets and industrial facilities.
Today, Penley Oil Company continues to evolve with the industry, offering cutting-edge solutions like bulk DEF supply, automated delivery programs, and comprehensive tank management services. Yet our core values remain unchanged: reliability, quality, and exceptional customer service.
