AMSOIL Ea™ Oil Filters

Revolutionary Technology

AMSOIL is continually searching for new and innovative technologies. With the advent of the nanofiber filtration media, AMSOIL desired to be on the cutting edge and provide the most innovative oil filter technology for the auto/light truck market. Nanofiber technology has been used exclusively in heavy-duty applications, including the US ARMY Abrams M1 tank, and now AMSOIL has brought this technology to the auto/light truck market. Nanofiber is a phrase generally referring to a fiber with a diameter less than one micron.
     The synthetic nanofiber technology found in AMSOIL Ea™ Oil Filters provide a higher level of engine protection than the conventional cellulose and blended medias found in most other oil filters. As shown in the photos below, cellulose fibers are larger than nanofibers and have larger spaces between the fibers, causing the contaminants to load inside the depth of the media and plug the flow path, resulting in higher restriction and less capacity. The fibers in synthetic media have submicron diameters (nanofibers) and small inter-fiber spaces, which result in more contaminants being captured on the surface of the media and lower restriction. This results in greater efficiency and capacity than cellulose filters, as well as better durability and longer service life.

Oil Filtration Basics

Clean oil is vital to engine performance and durability. Oil must lubricate, cool and clean the engine as it circulates. In order to remain effective, oil must be filtered as it cycles. Internal sources of oil contamination include wear products from the rubbing surfaces of the engine, blow-by gases leaking past the rings of the pistons and degradation of the oil itself. The oil filter removes these contaminants, preventing them from reaching sensitive engine parts, without restricting normal oil flow to the various parts of the engine requiring lubrication. A filter must perform well in the areas of efficiency, capacity, flow and filter life.

Absolute Efficiency

Efficiency is the filter’s ability to capture contaminants. The more efficient an oil filter is, the more contaminants it will remove from the oil. To make an oil filter more efficient, the spaces between the fibers in the media are made smaller, creating more resistance and limiting the oil’s ability to flow through the filter. Achieving maximum efficiency along with limited resistance is critical to good filtration.
     As shown on the graph, extensive testing shows that AMSOIL Ea™ Oil Filters achieve a near-perfect absolute efficiency rating. The exclusive new technology used in AMSOIL Ea™ Oil Filters provides filtering efficiency to 98.7 percent at 15 microns, whereas conventional brand name synthetic blend filters receive an efficiency rating of 80.23%. Conventional name brand paper oil filters receive an efficiency rating of only 39.39%! AMSOIL Ea™ Oil Filters are the most efficient filters that are available for auto/light trucks.

Maximum Capacity

Capacity is the amount of contaminants a filter can hold and still remain effective. When an oil filter reaches maximum capacity, the oil bypasses the filter and continues to circulate, unfiltered, throughout the engine. When an oil filter reaches maximum capacity it also reaches the end of its life and must be changed.
     AMSOIL Ea™ Oil Filters have a far greater capacity than competing oil filters. When used in conjunction with AMSOIL Synthetic Motor Oils in normal service, AMSOIL Ea™ Oil Filters are guaranteed to remain effective for 25,000 miles or one year, whichever comes first.

Improved Flow

Proper oil flow is essential to keep moving parts lubricated at all times. A filter without adequate flow properties can cause catastrophic engine failure. Flow is restricted as the spacing in the filter media is made smaller to provide greater efficiency.
     The synthetic nanofibers in AMSOIL Ea™ Oil Filters allow maximum efficiency without restricting oil flow. This provides unsurpassed cold-start performance and ensures proper levels of lubrication throughout the engine.

Here's how the nanofiber technology 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.

Durable Construction

AMSOIL Ea™ Oil Filters are made with premium-grade full synthetic media. The strictly controlled processing of this media ensures accurate fiber construction and allows AMSOIL Ea™ Oil Filters to deliver higher capacity and efficiency, along with better durability.
     Over the service life of a cellulose filter, hot oil will degrade the resins that bind the media. AMSOIL Ea™ Oil Filters’ full-synthetic-media technology uses a wire screen backing that is pleated with the media for superior strength. AMSOIL Ea™ Oil Filters are constructed with HNBR nitrile gaskets that are fully tested to extreme distances in numerous severe environments. The filters also feature fully tucked seams, a molded element seal, roll-formed threads and a long-lasting premium-grade silicone anti-drainback valve.
 

Extended Service Intervals

AMSOIL Ea™ Oil Filters are guaranteed for 25,000 miles or one year, whichever comes first, when used in conjunction with AMSOIL Synthetic Motor Oil in normal service. For severe service, they are guaranteed for 15,000 miles. These intervals coincide with the AMSOIL 25,000-mile/one-year motor oil drain interval, adding even more convenience for motorists by consolidating routine maintenance. AMSOIL recommends changing the oil filter at the time of oil change.
     AMSOIL EaO Filters are not guaranteed for 25,000 miles when used with any oil other than AMSOIL Motor Oil and should be changed according to vehicle OEM recommendations.    

Buying an AMSOIL Ea™ Oil Filter and AMSOIL long-life synthetic lubricants makes sense because there are fewer dirty oil filters to throw away, less waste oil and fewer empty oil bottles to dispose of, which is better for the environment!

Product Warranty

AMSOIL warrants that its filtration products are fit for use according to AMSOIL's recommendations and warrants its products to be free of defective materials, design and workmanship.
