AMSOIL EaO Nanofiber Oil Filters Cut Wear Rates 70% and Last One Year

The shocking truth is that not one vehicle OEM publishes a specification for the efficiency of oil filters.  Coincidence?  No, they want us to continue using cheap 1960’s filter technologies with 21st century manufacturing efficiencies, because those wear particles slowly wear out the engine… which sells not only repair parts, but new vehicles.

Do you think hospital clean rooms use cellulose (wood-fiber paper) filtration media?  Electronics manufacturing?  Military equipment?  No way.

In fact, one of the most important technologies enabling the punishing, fearsome superiority of the M1A1 Abrams battle tank is nanofiber filtration.  The Abrams can drive through a sandstorm and come out the other side roaring into battle, no problem.  Nanofiber filtration has been around for decades. Why is it so powerful and so important?

Full-flow filters install directly into the line of oil circulation. The full flow of oil passes through the filter as the oil journeys between the oil pump and engine. A full flow filter must be capable of removing and holding contaminants without obstructing oil flow to the engine.

Most conventional filters on the market use a thin layer of porous filter paper as their filtration media, which compromises their ability to catch fine particles. In addition, these filters have almost no extended cleaning ability since their media have a low capacity for storing dirt.

Because of their limited filtering area, most conventional paper filters display good flow characteristics but are restricted in their capacity and longevity. They become obstructed relatively quickly, opening the relief valve and allowing unfiltered oil into the engine. Their lightweight construction also makes them susceptible to degradation, and the common media binders begin breaking down after six months – eventually releasing both wear particles and media fibers into the oil system.

The four problems with standard engine oil filters are:

  1. non-removal of wear particles;
  2. media that starts coming apart after 6 months;
  3. gaskets that don’t endure and make filter removal difficult;
  4. bypass valves that open increasingly as the media gets clogged, letting unfiltered oil pass through.

AMSOIL’s Ea oil filters address all four problems. Check out this top-quality oil filter design:

Exploded View of AMSOIL EAO nanofiber Oil Filter construction and design


AMSOIL EaO filters are the only filters in the automotive market which use nanofiber media, and produce a 70% wear-rate reduction compared to other full-flow filters.  Tested according to the Society of Automotive Engineers industrial standards, EaO filters feature an advanced nanofiber media and ultra-premium construction that filters the oil flow of even the hardest-working engines with superior capacity, efficiency and service life.  They completely outclass the conventional paper oil filters which have been used for the last 40 years, in every way.  AMSOIL EAO15k filters may be used for intervals of 15,000 miles or one year (whichever comes first), and EAO25k filters last one year or 25,000 miles in gasoline engine applications.

The SAE agrees that 5 to 25 microns is the wear-particle size range that causes engine damage.  Yet conventional filters reach 98% efficiency typically at about 20-25 microns, and lose most of their capability by the time particle size drops to 15 microns.  In contrast, AMSOIL’s EaO nanofiber oil filters provide unmatched full-flow filtering efficiency to 98.7 percent at 15 microns, and 50 percent at 7 microns.

This translates to a 70% reduction in engine wear rates, while giving longer filter life and lower pressure drop for better cold-start performance: the only filtration that gives you the best performance in every category!  Compare that to the filters lining the auto-parts shelves, which don’t tell you their common 7,500 mile design life and either won’t tell you what micron level their efficiency rating is for, or they claim a micron particle size without stating an efficiency: deceptive, meaningless numbers.

What about cost?  AMSOIL’s filters last a year or 15k to 25k miles, and cost roughly $10 – 15.  This makes them equal to or cheaper than using standard oil filters, except for the 70% wear-rate reduction and ending the frustration of getting the old oil filter to come loose. Go to the vehicle oil and maintenance page to plug in your vehicle and look up the AMSOIL EaO oil filter and cost.  Here’s the secret to buying at wholesale pricing.

AMSOIL United States and Canada the Filtration and Lubrication Gold Standards

AMSOIL has been in business since 1972 and was the first company in the world to develop an API (American Petroleum Institute) rated synthetic lubricant for automotive applications. They coined the phrase “extended drain intervals” 40 years ago with 25,000 mile drain intervals, and ever since then they have been defining the leading edge of lubrication technology, innovation and performance.  No other company in the world offers 25,000 and 35,000 mile oil changes, and AMSOIL guarantees their product performance. No-one else does that. AMSOIL is the Gold Standard in lubrication and filtration, and amazingly, their superior-performance products are cheaper to use.  The fact is, if you’re not using AMSOIL lubricants and filters, you’re wasting money.

We are here to help you and are at your service to assist you in your advanced technology lubrication and filtration needs.  We hope you will allow us to show you a proven better way.  We have many thrilled customers using AMSOIL products in their commercial, trucking, and fleet vehicles, as well as personal, family and recreational vehicles. And now, you know the AMSOIL secret, too.  Welcome to the AMSOIL family.
