How to Install an AMSOIL Ea15K88 Filter
This short video will show you everything you need to know about the installation of the AMSOIL Ea15K88 Oil Filter.

Less Restriction
AMSOIL Ea Oil Filters have lower restriction than conventional cellulose media filters. Their small synthetic fibers trap smaller particles and hold more contaminants which results in lower restriction. During cold-temperature warm-up periods, an Ea Oil Filter allows the oil to flow through the filter more easily than a typical cellulose filter does. As a result, lower restriction decreases engine wear.

Contaminant Retention
A filter’s capacity refers to the amount of contaminants it can hold and still remain effective. AMSOIL Ea Oil Filters have a greater capacity for small, wear-causing contaminants than competing filter lines. In fact, when used in conjunction with AMSOIL synthetic motor oils, AMSOIL Ea Oil Filters are guaranteed for up to 15,000 miles/one year, whichever comes first, or 25,000 miles/one year, whichever comes first, depending on application and severity of service.

Superior Construction
AMSOIL Ea Oil Filters are made with premium-grade full-synthetic media. The strictly controlled processing of this media ensures accurate filter construction. Therefore, it allows Ea Oil Filters to deliver higher capacity and efficiency along with better durability.

Over the service life of a conventional cellulose filter, hot oil will degrade the resins that bind the media. Most Importantly the Ea Oil Filters’ full-synthetic media technology is resin-free. In addition, It uses a wire screen backing that is pleated with the media which yields superior strength.

AMSOIL Oil Filter Construction

Ea Oil Filters are constructed with HNBR 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-drain valve. In addition, they also feature fluted cans for improved grip.

Applications And Recommendations
AMSOIL Ea Oil Filters provide superior oil filtration for cars and light trucks.

Service Life
When used in conjunction with AMSOIL synthetic motor oils, AMSOIL Ea Oil Filters are guaranteed for extended service life:

• Ea Filters designated with product code Ea15K are recommended for 15,000 miles/one year, whichever comes first, in normal or severe service.

• Ea Filters designated with product code EaO are recommended for 25,000 miles/one year, whichever comes first, in normal service or 15,000 miles/one year, whichever comes first, in severe service.

Oil Filtration Basics

Oil filters play a major role in the performance and longevity of an engine by removing contaminants and promoting proper oil flow.

Modern engines introduce more contaminants into oil than their predecessors. To compound the issue, oil sumps are shrinking, leaving fewer detergents and dispersants to help fight the by-products of the internal combustion process. An oil filter’s capacity must improve to contend with the additional contaminants. Capacity refers to the amount of contaminants a filter can hold while still remaining effective.

To understand the significance of capacity, it’s helpful to know the basics of oil filtration. Clean oil is vital to keeping engines running properly. The oil filter must remove contaminants introduced into the oil and prevent them from reaching sensitive engine parts without restricting normal oil flow. Internal sources of contamination include wear products from the rubbing surfaces of the engine, and degradation of the oil itself. To provide top-notch performance, a filter must be constructed with the optimum balance of capacity, efficiency, flow and  durability.

Advanced Media Technology

Cellulose and blended media found in most oil filters have larger fibers than the synthetic media found in Ea Oil Filters. They also have larger spaces between their fibers. This causes contaminants to load in the depth of the media and plug the flow of oil, resulting in higher restriction and reduced capacity. The smaller fibers in synthetic media also have a controlled size and shape. This results in greater efficiency and capacity than cellulose fil-ters, as well as better durability. AMSOIL Ea Oil Filters provide a higher level of engine protection and extended filter change intervals.

Absolute Efficiency

Efficiency is the filter’s ability to capture contaminants. The more efficient a filter is, the more contaminants it will remove from the oil. To make a filter more efficient the spaces between the fibers in the media are made small-er, 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.

The graph below shows that AMSOIL Ea Oil Filters achieve a near-perfect absolute efficiency rating. The exclusive technology used in AMSOIL Ea Oil Filters provides filtering efficiency to 98.7 percent at 20 microns. Ea Oil Filters are among the most efficient filters available for auto/light trucks.

Maximum Capacity

Capacity is the amount of contaminants a filter can hold and still remain effective. When a filter reaches maximum capacity the oil continues to flow through unfiltered, leaving harmful contaminants circulating in the oil. When a filter reaches maximum capacity it also reaches the end of its life and must be changed.

AMSOIL Ea Oil Filters have greater capacity than competing filter lines, pro-viding convenience and cost savings through extended service intervals.

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 fail-ure. Flow is restricted as the spacing in the filter media is made smaller to provide greater efficiency. The synthetic media in AMSOIL Ea Oil Filters al-low maximum efficiency without restricting flow. This provides exceptional cold-start performance and ensures proper levels of lubrication throughout the engine.

Durable Construction

AMSOIL Ea Oil Filters are made with premium-grade full-synthetic media. The strictly controlled processing of this media ensures accurate fiber con-struction and allows Ea Oil Filters to deliver increased durability. Over the service life of a cellulose filter, hot oil will degrade the resins that bind the media. Ea Oil Filters’ full-synthetic media technology uses a wire screen backing that is pleated with the media for superior strength. 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-drain valve.

Extended Service Intervals

When used in conjunction with AMSOIL synthetic motor oil, AMSOIL Ea Oil Filters are guaranteed for extended service life:

• Ea Filters designated with product code Ea15K are recommended for 15,000 miles/one year, whichever comes first, in normal or severe service.
• Ea Filters designated with product code EaO are recommended for 25,000 miles/one year, whichever comes first, in normal service or 15,000 miles/one year, whichever comes first, in severe service.

Consult the AMSOIL Online Application Guide or MyAMSOILGarage™ at www.amsoil.com to determine the appropriate filter for each application. When AMSOIL Ea Oil Filters are used with a motor oil other than an AMSOIL extended drain motor oil the filter should be changed according to the vehicle manufacturer recommendation.
