About Petroleum Service Company

Petroleum Service Company is a family-owned distributor based in Ashley/Wilkes-Barre, Pennsylvania, and it has been trading since its founding in 1924. It started out with industrial lubricants and oils and has since become a substantial online retailer. Its range takes in manufacturing lubricants, greases, fuel additives and protective coatings, along with equipment and accessories, and it supplies commercial, automotive and industrial customers across the nation. Close supplier relationships and an emphasis on quality shape how it buys and sells, and the website is set up so buyers with varied petroleum needs can order without hassle. Lubricants and greases are used to cut friction in engines and machinery, while fuel additives are meant to improve how fuel behaves.

Customers can pay with PayPal, Google Pay or Apple Pay. Anything sent back has to reach the company within 30 days of the purchase date, unopened and in factory new condition, and a 20% restocking fee applies to returns, with a 2.85% fee when a return is processed on a credit card.

There are a few routes to savings. Subscribing to the newsletter brings regular updates on clearance sales, bulk discounts and other deals, and larger quantities of lubricants, fuels or other petroleum products often qualify for a lower price per unit. The clearance section spans lubricants and additives as well as equipment and accessories. The PSC Premium Rewards program hands out tiered gifts to shoppers who spend $1,000 to $2,999, and PSC Select Shipping provides exclusive shipping deals; either one is open to anyone who registers an account on the website. The company also keeps accounts on Facebook, Twitter, YouTube, Instagram, Pinterest and LinkedIn.
