Compared to microscopic dirt particles, your engine is a Goliath, roaring with heat and energy as it converts fuel into raw horsepower. But despite all this power, your engine is extremely vulnerable to the threat of microscopic engine dirt. In fact, if unchecked, this tiny menace will dramatically erode your engine's performance and can eventually cripple it beyond repair.

AMSOIL Ea Oil and Air Filters are the key to preventing costly repairs caused by engine dirt. Filtration is simply a method of removing contaminants by trapping and holding them outside the system. In order for filtration to be truly effective, however, it must be able to capture contaminants of all types and sizes.

AMSOIL Introduces Revolutionary Nanofiber Filter Media Technology!

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.  

Fast Fact: A nanofiber is less than one micron in diameter. A human hair is 80 microns.

The Ea By-Pass Oil Filters provide the best possible filtration, protection against wear and oil degradation. Working in conjunction with  the engine’s full-flow oil filter, the AMSOIL Ea By-Pass Filter operates  by filtering oil on a “partial-flow” basis. It draws approximately 10 percent  of the oil pump’s capacity at any one time and traps the extremely small, wear-causing contaminants that full-flow filters can’t remove. The  AMSOIL Ea Bypass Filter typically filters all the oil in the system several  times an hour, so the engine continuously receives analytically clean oil. 

AMSOIL EaBP Filters have an efficiency of 98.7 percent at two  microns. At normal operating RPMs the EaBP Filter will filter all of  the oil in a typical five quart sump in less than 10 minutes.

By-Pass Filtration Benefits

• Dramatically Extended Drain Intervals
• Improved Oil Cooling
• Increased Filtration Capacity and Life
• Increased Fluid System Capacity
• Efficient Small Particle and Soot Removal
• Significantly Extended Engine Life
• Equipment Constantly Runs on Clean Oil
• Increased Engine Efficiency
• Remove Particles Less Than One Micro

Absolute Efficiency

AMSOIL Ea Air Filters are the most efficient filters available to the car/light truck market. Ea Air Filters’ synthetic nanofiber media removes 5 times more dust than traditional cellulose filter media alone and 50 times more dust than wet gauze filter media. AMSOIL Ea Air Filters have a service life of 100,000 miles or four years, whichever comes first.

Better Air Flow

AMSOIL Ea Air Filters allow more airflow than filters that use cellulose media alone. Cellulose fibers are larger than nanofibers, and have larger spaces between the fibers, causing contaminants to load in the depth of the media and plug the airflow path, which results in higher restriction and less capacity. The synthetic nanofibers in EaA Filter media have submicron diameters and small interfiber spaces, which result in more contaminants being captured on the surface of the media and lower restriction.  

Donaldson® Endurance™ air and oil filters are made with advanced synthetic and nanofiber technology that results in fibers that have a controlled size, down to submicron diameters. Donaldson® Endurance™ air and oil filters, provide the highest level of filtration efficiency in the industry. Specifically designed for on-road, heavy-duty class 6, 7 and 8 vehicles,

Endurance™ Air Filters offer longer engine life, longer filter life, initial efficiency up to 99.99 percent and five times more capacity than conventional cellulose filters. Endurance™ air filters come with a “twice the miles” guarantee to deliver twice the miles between change intervals over cellulose air filters for on-highway applications, or customers receive a new filter at no charge.

Eliminating complete teardowns based on guesswork
Enabling better assessment of equipment performance

How the Oil Analysis Program Works

TRIGARD Engine Protection Plan

Superior Motor Oil
The key to extending drain intervals is the oil you use. AMSOIL Synthetic Motor Oil was the first and may be the only 25,000-mile motor oil on the market. Today AMSOIL manufactures a number of high-quality long life synthetic motor oils. Because AMSOIL Motor Oils are synthetic lubricants, they withstand temperature extremes within an engine without breaking down like conventional petroleum oils. They provide excellent protection at high temperatures and easier starting at sub-zero temperatures. Kept clean, they will last indefinitely to cool, clean and reduce friction and wear for the best possible fuel economy and the longest possible engine life.

Superior Air & Oil Filters
 Dirt is your engine’s worst enemy and the single major cause of engine wear. AMSOIL TRIGARD utilizes two extremely effective filters to keep airborne dirt from entering your engine through the engine air intake, and continuously filter contaminants and combustion by-products from the engine oil. First, install an AMSOIL Ea Air Filter. AMSOIL Ea Air Filters are made with nanofiber synthetic media that is available only from AMSOIL. Ea Air Filters boast the highest efficiency rating of any air filter on the market, along with greater capacity and less restriction than competing filters. Then install the AMSOIL Ea By-Pass Filter along with an AMSOIL Ea Oil Filter Ea By-Pass Filters feature higher filtering efficiency, soot removal and increased oil capacity. They also have a silicone anti-drain back valve and HNBR nitrile gasket for better sealing and increased longevity, as well as a zinc dichromate coated base plate for great corrosion resistance.

Superior Engine Monitoring
Regardless of the kind of oil or filters used, mechanical problems in an engine are not always noticed until it is too late. Engine monitoring can save you the cost of major engine repairs or a new engine. By analyzing used engine oil, a qualified lab can detect mechanical problems your engine may have. To insure that your engine is performing properly, the TRIGARD plan includes a first-time oil analysis between 1,000 and 6,000 miles. The second analysis is performed after one year or 25,000 miles, whichever comes first. (12,500 miles on diesel or turbocharged vehicles)   Continued oil analysis at six-month or 12,500-mile intervals will monitor the condition of your oil and your engine. The long-term oil analysis program has been shortened to six month or 12,500-mile intervals due to stress made by modern engine designs. Today’s engines run hotter, are equipped with more pollution control equipment, and have higher weight-to horsepower ratios. Another reason for more frequent testing intervals is that motor fuels, including gasoline and diesel, have steadily declined in quality and cleanliness. Getting a sample of used engine oil from your engine is a simple procedure using oil sample bottles included with the TRIGARD plan and the petcock available for the by-pass filter. This procedure assures many thousands of miles of trouble-free driving.
