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
Small, consistent synthetic fibers trap smaller particles and hold more contaminants, resulting in lower restriction.		Cellulose fibers are inconsistent in size and shape, allowing more contaminants to pass through, resulting in higher restriction and lower capacity.
