Lubricant Solutions that Reduce Friction and Wear So You Can Move Things Forward

People will never stop inventing engines and equipment that improve how things move. Warren Distribution will continue to innovate and manufacture lubricants and automotive chemicals that support designers, engineers, and others across thousands of applications. Our products help reduce friction, wear, and deposits that would otherwise inhibit progress.

More Than 90% of THE Products We Manufacture are Private Label Lubricants.

Private Label lubricants are growing very rapidly while the market share of most brands from global oil Majors has been flat or shrinking. The reasons are simple - more people recognize parity in product quality, demand lower prices and higher-margin opportunity they can enjoy with private label lubricants. The same trend is evident in mass merchandise and grocery segments, where private label brands account for about 40% of all products on the shelf, according to many experts.

Private lubricant brands represent nearly 50% market share, by volume, in the DIY retail segment.

The volume of lubricants sold by Wholesale Oil Distributors is now estimated to be 25-30%. And it has been growing by 7-12% a year.

OEMs have been selling genuine or private label brands for decades.

Our Lubricant Formulations, Testing, Blending and Operations Are Accurate and Cost-Efficient So We Can Optimize Innovation, Quality, and Value to Our Customers.

Our hundreds of lubricant formulas are innovated and blended to meet the quality and value needs of our customers. Our product development and technical teams work closely with our additive company partners to constantly explore new ways to make improvements that meet the changing landscape of customer and competitive demands, as well as changes in industry or OEM requirements and standards. We have four full laboratories, one at each manufacturing facility, to help develop products, assure quality and test all incoming and outgoing fluids.

We never compromise product quality and compliance with customer, industry or OEM requirements and standards. To maintain these standards, our labs test every batch of lubricants produced at all the plants every day and retain samples for future reference. Our engine oils meet or exceed American Petroleum Institute (API) requirements and have passed its rigorous tests for each product. For example, below are the 17 tests our CK-4 heavy-duty engine oils must pass for API approval.
