AMSOIL is partnering with Fleece Performance Engineering, a leading manufacturer of aftermarket diesel performance products based in Pittsboro, IN. Fleece Performance manufactures everything from turbochargers to cylinder heads and long blocks, while Freedom Racing Engines operates as a separate division of the company. Fleece Performance is one of the most recognized names in the high-performance diesel market and boasts a solid reputation for innovation, quality and service. This high-profile partnership, once again, validates AMSOIL’s leadership and elevates AMSOIL’s visibility with diesel enthusiasts.
Fleece Performance selected AMSOIL to engineer a new line of co-branded lubricants to be launched in the spring of 2026. The new AMSOIL and Fleece Performance Freedom Series line of diesel products will include 10W-30, 5W-40 and 15W-40 Synthetic Diesel Oil; 15W-50 Synthetic Racing Oil; and SAE 30 Break-In Oil.
The new product line will not be available in Canada. Fleece has a small but growing presence in Canada, so we are hopeful that will change in the future.
