AMSOIL Ea Oil Filters (EaO)
Made with premium-grade full synthetic media. Ea Oil Filters feature advanced full synthetic nanofiber technology, making them the highest efficiency filters that are available for the auto/light truck market. AMSOIL EaO 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. In severe service, change oil and filter at recommended severe service oil drain interval.

Absolute Efficiency
AMSOIL Ea Oil Filters (EaO) have the best efficiency rating in the automotive/light-truck market. EaO Filters provide a filtering efficiency in accordance with industry standard ISO 4548-12 of 98.7 percent at 15 microns, while competitive filters containing conventional cellulose media range from 40 to 80 percent efficiency.

Less Restriction
AMSOIL Ea Oil Filters have significantly lower restriction than conventional cellulose media filters. Their small synthetic nanofibers trap smaller particles and hold more contaminants, resulting in lower restriction. During cold temperature warm-up periods, an EaO lube filter allows the oil to easily flow through the filter compared to a typical cellulose filter. Lower restriction decreases engine wear.

More Capacity
A filter’s capacity refers to the amount of contaminants it can hold and still remain effective. AMSOIL EaO Filters have a greater capacity for small, wear-causing contaminants than competing filter lines do. In most applications, when used in conjunction with AMSOIL synthetic motor oils in normal service, EaO Filters are guaranteed to remain effective for up to 25,000 miles or one year, whichever comes first.

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, and is what 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. The Ea Oil Filters’ full synthetic media technology is resin-free. It uses a wire screen backing that is pleated with the media for superior strength.

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.

Service Life
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. AMSOIL recommends changing the oil filter at the time of oil change.

Some more useful info for you guys ;)

A great deal of emphasis is placed on the importance of using of the most advanced high-quality lubricants, but superior filtration is often taken for granted. The general attitude displayed by many consumers is to use whatever is cheapest, even when they’ve invested in superior lubrication. While AMSOIL synthetic motor oils provide unbeatable protection, performance and economy, they require the assistance of filtration. Without filtration, by-products from the combustion process and abrasive materials ingested from the air will ultimately destroy an engine.

Some Contaminants Cause More Damage

The level of damage particles cause to an engine is directly related to the size of the particles. The oil stream within the engine flows between wear-sensitive surfaces that usually have clearances between 2 and 22 microns. It is contaminants in this size range that pose the greatest threat as they can slip between moving components, causing a great deal of wear.

To appreciate how small these particles are, one must first understand the measurements involved in their classification.

A micron, or micrometer (µ), is a very small unit of linear measurement. One micron is equal to one millionth of a meter, and 25 microns is equal to 0.001 inch. To better put this in perspective, consider that the diameter of a human hair is 50 - 70 microns.

Large particles are particles measuring 1/2” or larger. They pose little threat to engines because they are easily removed by the air filter.

Medium particles are particles measuring 25µ to 1/2”. While they are of greater concern than large particles because they are more difficult to remove, the threat they pose is diminished since they are still larger than many of the clearances within an engine. Their size will not allow them to enter the contact areas between many components to promote accelerated wear.

Small particles are particles measuring between 5 and 25µ. Small particles are of greatest concern because they can penetrate the clearances between wear-sensitive components and promote accelerated wear. And, because they are so small, they are difficult to remove from the oil stream.

SAE Testing

In the 1988 Correlating Lube Oil Filtration Efficiencies With Engine Wear technical paper published by the Society of Automotive Engineers (SAE), the relationship between filtration levels and abrasive engine wear was established. Testing determined that wear was reduced by as much as 70 percent by switching from a 40µ filter to a 15µ filter.

The SAE conducted tests on a heavy-duty diesel engine and an automotive gasoline engine, and both provided consistent results.

New Technology Provides New Options

The SAE paper on filtration discusses the introduction of synthetic fibers into the oil filter market, which offer “the capability of achieving high levels of filtration without the traditional sacrifice of dirt holding capacity and increased flow restriction.” Today, a new pinnacle has been reached with synthetic nanofiber technology and AMSOIL Ea Oil Filters. While today’s filters offer even greater performance, the message then was the same as it is now; removal of particles measuring 2 to 25µ is the key to controlling engine wear, and there is a direct correlation between oil filter efficiency and engine wear.

Test Results

To establish a relationship between levels of filtration and engine wear rates, the SAE used a variety of oil filter types in its tests. Three glass filters and one traditional cellulose-media filter were used in the diesel tests, while one cellulose, one glass and two glass/cellulose-blend filters were used in the gasoline engine tests. The micron rating of each oil filter was determined, and testing was conducted according to SAE guidelines.

The Filter Particle Retention Curves chart on the next page shows the particle retention for each filter tested. The filters were tested at their 98 percent efficiency point and their single pass efficiency curves were determined by comparing the number of particles upstream from the filter with the number of particles downstream. The Engine Wear Rates charts demonstrate the correlation between superior filtration and reduced engine wear. The filters that provided superior efficiency also provided superior engine protection.

Conclusions

The SAE paper summarizes the test results with the following conclusions:

"Abrasive engine wear can be substantially reduced with an increase in filter single pass efficiency. Compared to a 40µ filter, engine wear was reduced by 50% with 30µ filtration. Likewise, wear was reduced by 70% with 15µ filtration."

"Controlling the abrasive contaminants in the range of 2 to 22µ in the lube oil is necessary for controlling engine wear."

"The micron rating of a filter, as established in a single pass efficiency type test, does an excellent job in indicating the filter’s ability to remove abrasive particles in the engine lube oil system."

Today’s Most Advanced Filtration Product

Ea Oil Filters have been evaluated using today’s benchmark test, the ISO 4548-12 multi-pass test. AMSOIL Ea Oil Filters provide 98.7 percent efficiency at 15µ and up to 70 percent efficiency at 7µ. Competitive filters range from approximately 85 to 92 percent efficiency at 15µ. When it comes to removing contaminants in the most critical size range (2 to 22µ), AMSOIL Ea Filters greatly outperform competitive filters.

Summary

Even with all of the advances in lubrication and engine technology, filtration is as important today as it ever was. The combustion process produces by-products that slip into the oil stream, and external contaminants are introduced into the engine in a variety of ways. The challenge for filter manufacturers is balancing flow, efficiency and filter life. In order to stop particles in the 2 to 22µ range, the pores in the cellulose media used in many filters are too small to allow adequate oil flow.

Only AMSOIL Ea Oil and Air Filters feature full-synthetic nanofiber technology. It is the nanofibers that allow Ea Filters to provide greater efficiency than any other filter available. Ea Filters stop more particles, stop smaller particles and last longer than any other oil filter available for auto/light truck applications.
