Donaldson Endurance™ oil filters are made with premium advanced synthetic media technology that results in fibers that have a controlled size, shape and smaller fiber diameter. 

The controlled media manufacturing process allows Donaldson Endurance™ oil filters to deliver both higher dirt holding capacity at the same pressure differential and higher efficiency compared to conventional cellulose filters. The synthetic media also has better durability with usage.

Throughout the service life of a cellulose filter, hot oil will degrade the resins that bind the media. The synthetic media technology uses a wire screen backing pleated with the media, resulting in superior strength.

Donaldson Endurance™ oil filters offer extended service intervals, greater engine protection to prolong engine and equipment life, improved lubricant flow, improved cold start performance and lower operating costs.

Donaldson Endurance™ Oil Filters With Nanofiber vs. Conventional Cellulose
Red circles represent the diameter of a 2 micron and a 5 micron particle. Nanofibers have submicron diameters and small interfiber spaces, which result in more contaminant being captured on the surface of the media and lower restriction. Red circles represent the diameter of a 2 micron and a 5 micron particle.	Red circles represent the diameter of a 2 micron and a 5 micron particle. Cellulose fibers are larger than nanofibers, and have larger spaces between the fibers, causing contaminant to be held in the depth of the media and plug the airflow path; resulting in higher restriction and less capacity.
