AMSOIL carries Donaldson filtration products to meet every heavy-duty filtration need. Donaldson Filters are widely regarded as the best there is in the filtration world. AMSOIL offers products from Donaldson’s Endurance line, Donaldson P-Series and Donaldson PowerCore filters.

Donaldson Endurance
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.

Air Filters
Endurance air filters offer longer engine life, longer filter life, initial efficiency up to 99.99 percent and five times more capacity than conventional cellulose filters.

Endurance air filters come with a “twice the miles” guarantee to deliver twice the miles between change intervals over cellulose air filters for on-highway applications, or customers receive a new filter at no charge.

The nanofiber technology traps submicron contaminants on the surface rather than dispersing them throughout the depth of the filter where there is less area for the air to flow. Therefore, in on-highway applications, where the contaminant is primarily submicron in size, Endurance air filters cause less restriction than conventional filters with cellulose media. The smaller, interfiber spaces have higher efficiency and capture more contaminants.

Here’s how it works: Imagine two filtration media, a chain link fence and a mosquito net. Each is required to stop contaminants, in this case tennis balls. A tennis ball will fit quite nicely into an opening of a chain link fence, but will obstruct the hole almost 100 percent. Now, imagine a tennis ball covering a mosquito net. The tennis ball, at the point of contact with the netting, will obstruct much less filter area than the chain link fence example. In fact, air will flow around the tennis ball all the way to the point of contact. It will take many more particles to obstruct the netting surface area than the chain link fence.

Oil Filters
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 heavyduty
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

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.

P-Series
With many applications that differ from, and several that coincide with the Endurance line, Donaldson P-Series filters offer premium filtration at a competitive price. Donaldson P-Series filters feature housing constructed with heavy gauge steel and domed construction, providing superior pressure fatigue performance. Donaldson PSeries oil filters are constructed with either full synthetic media or synthetic blends for high efficiency. The center tube allows more flow without compromising strength, and the louvered design eliminates tearing during pleat movement. The media is embedded deeper into the sealing plastisol than conventional filters, allowing better sealing longevity. Additional features include a nitrile sealing gasket, a fully tucked seam, roll formed threads and a compression spring holding all the components in place within the filter. AMSOIL carries Donaldson P-Series oil, air, fuel, hydraulic and coolant filters.

Greater Capacity
Donaldson P-Series filters hold more contaminant than the original equipment oil filter. The more capacity a filter has for holding contaminants, the longer the filter will perform. The longer the filter lasts, the more miles an engine can run without a filter change.

Fuel Filtration
Today’s engines are built to more stringent specifications and finer tolerances. Fuel systems, pumps and injectors require cleaner fuel to achieve better combustion and lower emissions. Donaldson fuel filters provide clean, filtered fuel that prevents pump wear, injector clogging, premature engine wear and can boost fuel efficiency. AMSOIL carries a complete line of spin-on and cartridge-style filters.

Coolant Filtration
Engine cooling systems keep engine temperatures at the right level to dissipate heat and maintain the right operating conditions for optimal fuel economy. Donaldson coolant filters remove contaminants, minimize the risk of filter plugging and keep your engine running efficiently.

Hydraulic Filters
Donaldson industrial hydraulic filters provide excellent protection for machinery and components in hundreds of applications in factories and on heavy-duty equipment. Donaldson provides filter housings, filter heads, replacement cartridges, spin-ons and hydraulic accessories.

Donaldson P-Series Filter Features

• Unique wide-mouth cartridge outflow that allows
  unobstructed oil flow from the filter media, consistently
  delivering the maximum flow available.
• Multi-density Synteq filter media holds more contaminants,
  meeting and even exceeding performance
  specifications for Cummins diesel engines.
• Superior filter cartridge design that permits 38 percent
  more full-flow surface area and therefore, the engine oil
  continually receives high-efficiency filtration.

PowerCore Filters
AMSOIL offers premium air filters that utilize PowerCore filtration technology. The rugged structure of PowerCore filters features an innovative, layered, fluted filter media, which allows air to enter an open flute while forcing it out an adjacent flute, allowing only clean air into the engine. Dirty air is effectively filtered and cleaned in only one pass through the media.

AMSOIL carries the entire line of Donaldson PowerCore filters that provide less restriction and greater power. Applications include the Ford 6.0L PowerStroke™ Diesel, GM H2 Hummer 6.0L Vortec, certain models of John Deere tractors and Freightliner M-2 engines, as well as an air induction box for Ford 7.3L PowerStroke Diesels.

Expanded Market
Truck sales represent the fastest growing segment of the U.S. automotive market. Fifty percent of new vehicles sold today are trucks. Now, AMSOIL has expanded that market even further with the addition of premium filters for the Ford 6.0L Diesel PowerStroke engine and the GM H2 Hummer 6.0L Vortec.

Innovative Design
The design of the U.S. and internationally patented housings, filters and filter media are key to Donaldson PowerCore filtration technology. Donaldson PowerCore filter media is formed into flutes. These flutes are layered to give tight, rugged structure to the filter. The fluted channels are alternately sealed allowing
air to enter through an open flute and forcing it to exit out an adjacent flute. The dirty air travels in and is filtered in one pass through the media.

Improved Efficiency and Protection
Donaldson PowerCore filters are 10 times more efficient than average conventional filters.PowerCore filters provide improved contaminant encapsulation, over 100 percent more dust holding capacity in a given volume.That means dust and dirt won’t dislodge during servicing.

The straight-through fluted filter design improves engine protection because there is no media movement, expansion, contraction or bunching. There is also less dust and dirt passed on to the engine. The fluted design keeps contaminants inside the filter, preventing contamination of the unprotected air filter housing.

Improved Handling and Maintenance
PowerCore filters are lighter and smaller, making filter changes much easier. Their non-metal, incinerable construction makes them easier to dispose of.

Donaldson 7.3L Power Stroke Diesel Air Induction System
AMSOIL offers a new air induction system from Donaldson. The new system brings better performance to Ford owners. Diesel engines need clean, unrestricted air for optimal performance. The new Donaldson 7.3L Power Stroke Diesel air induction system with PowerCore technology provides better air filtration through better engineering.

The PowerCore Air Induction System (PCIS-73) replaces the present air intake system and utilizes a Donaldson PowerCore filter to provide unmatched performance and filtering efficiency on 1999 through 2003 model year F-250 to F-550 Super Duty trucks and SUVs with 7.3L PowerStroke Diesel engines.

Greater Filtering Efficiency
The Donaldson air induction system is three times more efficient than the industry leading cellulose media. The layered structure from PowerCore technology is totally non-metallic and allows for 99.95 percent efficiency. The highly efficient Donaldson PowerCore air filter is the only aftermarket induction
system that is approved by Ford Motor Company.

Easy Installation
The new air induction system kit comes with the air filter box fitted with a PowerCore filter, air restriction gauge, temperature sensor, air inlet duct, battery blanket, battery box plate, necessary fasteners and complete installation instructions. The kit installs in 35 to 40 minutes and there are no extra parts to buy. (Early 1999 models require an additional clean air hose available from Ford.)

Greater Filter Capacity
More capacity means more engine protection. The PowerCore air filter has over 16 times more media surface area than washable filters, and 3 times the media surface of conventional filters. The PowerCore air filter has five times more dust holding capacity than washable/reusable air filters and twice the capacity over premium quality traditional filters. Greater capacity also means changing filters less often, even in more severe service situations. When the restriction gauge on the PCIS-73 reads in the red zone, change the filter as soon as possible.
