Dont be fooled, cheap filters do more damage than you think.

why use filters that let dirt pass into your engine even when new!?

AMSOIL filters last 10x longer, engine oil filters last one year or 25,000 miles, and air filters last 4 years or 100,000 miles used with AMSOIL motor oils

A great deal of emphasis is placed on the importance of using 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 of 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 25 Microns and Larger
Bearing Bearing 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 oil 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 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
oil 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 filters available for
auto/light truck applications.
