Donaldson Endurance Oil Filters

Endurance Filters

Donaldson® Endurance™ air and oil filters provide the highest level of filtration efficiency in the industry. Specifically designed for on-road, heavy-duty class 6, 7 and 8 vehicles, Donaldson Endurance air and oil filters feature exclusive nanofiber technology. Class 6 vehicles, 19,501 to 26,000 pounds gross vehicle weight (GVW), include single-axle vans, beverage trucks and school buses; class 7, 26,001 to 33,000 pounds GVW, include refuse trucks, tow trucks and city transit buses; class 8 trucks, 33,000 pounds GVW and greater, include fuel haulers, inter-city/tour buses and cement trucks.

OIl Filters

Small synthetic fibers trap smaller particles and hold more contaminants, resulting in lower restriction. Red circles represent the diameter of a 20-micron particle. Cellulose fibers are inconsistent in size and shape, allowing more contaminants to pass through, resulting in higher restriction and lower capacity.

Donaldson Endurance oil filters are made with advanced synthetic technology that results in fibers that have a controlled size, down to submicron diameters. This controlled process allows 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 and increased resistance to water.

Throughout the service life of a cellulose filter, hot oil degrades the resins in the media. The synthetic media uses a wire screen backing pleated with the media for superior strength and long term durability.

Endurance oil filters provide a filtering efficiency of 98.7 percent at 15 microns and 50 percent at 7 microns in accordance with industry standard ISO 4548-12. This is the best rating in the industry.

So whether extending maintenance intervals to the limit and running the engine for a million miles without an overhaul, maintaining a national fleet or running a coal mine, Endurance filters can lower total operating costs.

Using AMSOIL synthetic oils and the Endurance filters, with advanced synthetic technology, makes a superior extended drain combination.

AMSOIL will guarantee Endurance oil filters up to twice the manufacturer’s recommended service interval, to a maximum of 60,000 miles for heavy- duty diesel applications. Endurance filters are guaranteed to extend the customer’s drain interval when used under normal on-highway conditions while following these maintenance practices:

• Use of Endurance oil filter(s)
• Use of AMSOIL Synthetic Motor Oil
• General preventative maintenance practices performed in accordance with manufacturer’s recommendations.
• Engine in good operating condition prior to attempting extended drain intervals.

Engine Protection Filters Drive Costs Down Donaldson Endurance oil filters are made using exclusive advanced synthetic media technologies. Synthetic media technology delivers cost saving benefits with: Extended service life Greater engine protection Prolonged engine and equipment life Improved lubricant flow Improved cold start performance Reduced operating costs

Higher Efficiency Dirt and other small contaminants cause wear that reduces engine and equipment life. Endurance oil filters are more effective than cellulose media in removing these small contaminants.	Higher Capacity Contaminant holding capacity is a major factor in determining when a filter needs to be changed. Endurance oil filters have greater contaminant holding capacity than conventional cellulose filters.

Flow Restrictions During Cold Starts

	Better Engine Protection During Cold Starts Endurance oil filters have significantly lower restriction than conventional cellulose media filters. During the engine warm-up period, an Endurance oil filter allows the oil to flow through the filter at a colder temperature than a typical cellulose filter. The additional filtering time decreases engine wear.
	Improved Gasket and Grommet The Endurance filter’s high-grade material stays flexible and sealed during extended exposure to hot oils with advanced additive packages.
