Headquartered in Eastern Pennsylvania, Petroleum Service Company (PSC) was founded in 1924 and incorporated in 1930. We are homegrown, yet international. You may know us as a local brick-and-mortar distributor of oil and lubricants, but we’ve grown to become much more than that. PSC has led the market into the e-commerce business with a dedicated team of industry experts. We’ve embraced technology and are innovating the way that you shop for petroleum products, rust preventative coatings, and application equipment through our nationally recognized PSC Online Stores. Our team members demonstrate creativity, passion, and a drive to never stop working to improve your experience with us. You can now order immediately online because of our commitment to creating a fast, easy, and convenient online shopping experience. We are committed to the online shopping market for all our major product lines and we will work to make sure you’re happy with every product you buy from us. All PSC Online Stores provide the highest quality products and services to customers through supply chain innovation, product integrity, and sound supplier relationships.
