Family Owner & Operated Since 1985

Diesel Pro, a family-owned business founded in 1985 by Lance Donaldson, began as a small fuel remanufacturer in the basement of a farm house in Glen Rock, PA. Lance recognized the need for quality diesel service in South Central PA and aimed to produce one pump a week to support his family and local customers. As Diesel Pro’s reputation grew, so did the business, and Lance established strong relationships with manufacturers and built a full team to cater to the changing needs of customers.

As Diesel Pro expanded, its priority remained to maintain product quality and offer great value to customers. The company focuses on providing quality products that not only function well but also look appealing on the outside.

Scott Donaldson, Lance’s son, joined the family business in 2015 and now manages operations. In 2018, Scott & Lance looked at the future for Diesel Pro and began to utilize its long-standing manufacturer relationships to establish one of largest and most trusted online retail businesses for diesel parts, serving shops and customers across the US and Canada while continuing to work with their local customers for parts and repair service work.

Diesel Pro prides itself on being an honest, family-owned company that offers products on par with manufacturers at affordable prices, with customer satisfaction as a top priority. With over 30 years of experience in the diesel industry, Diesel Pro has emerged as a leading provider of diesel services and parts in York County, PA, operating out of a fully-stocked warehouse and full-service garage with a team of knowledgeable and experienced professionals who are passionate about the diesel industry. Whether it’s diesel parts or services, Diesel Pro is prepared to fulfill all your diesel-related needs.
