Bypass Oil Filtration

Reduce Engine Wear with AMSOIL Bypass Filtration Systems

AMSOIL Offers Products To Eliminate Microscopic Engine Dirt

Compared to microscopic dirt particles, your engine is a Goliath, roaring with heat and energy as it converts fuel into raw horsepower. 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.

Why Bypass Filtration?

The majority of engine wear comes from particles from 5µ to 25µ in size. (A “µ” micron is an abbreviated term for “micrometer”, or a millionth of a meter. For size comparison, a human hair is about 75 microns). The problem that arises is that the average full flow filter is only efficient for particles 20µ in size and larger. This means that all those particles under 20µ can pass though the filter and cause wear to your engine. This is where an AMSOIL BYPASS SYSTEM comes into play. Installing a Bypass System on your vehicle will efficiently filter particles down to 2µ in size, effectively reducing the wear on your engine.

Overall here are some of the benefits to using an AMSOIL Bypass System.

The high-efficiency AMSOIL Ea Bypass Filter element is also an effective soot-removal device. The filter element is composed of a highly efficient media, which increases soot-removal efficiency when the bypass filter is used in conjunction with a standard full-flow filter. AMSOIL Bypass Filters are rated at 2µ Absolute (BETA 75).

It’s like giving your engine an oil change every 10”. AMSOIL Ea Bypass Filters typically filter all of the oil in the system several times an hour, so the engine continuously receives analytically clean oil.

Analytically clean oil enables engines to run at peak efficiency.

The majority of engine wear is caused by particles in the 5-20 micron range. Because AMSOIL Ea Bypass Filters effectively remove contaminants down to 2 microns, your engine receives the ultimate in wear protection. Less engine wear keeps the engine in better physical condition, extending its life.

An additional filter adds additional opportunity to filter particles out of the oil. The full-flow filter removes larger particles down to about 20 microns, while the bypass filter removes the smaller particles down to 2 microns. Working together, these filters provide next-level protection for your engine.

With increased oil capacity, the oil filtration system contains more fluid through which it can disperse heat from the engine. This allows the engine and the oil to run cooler.

By installing an additional filter, the engine system has the capacity to hold more oil. The increased fluid capacity and filtration life ensures the equipment constantly runs on highly filtered oil. Engine efficiency is increased, providing extended engine life.

AMSOIL Bypass Systems provide a dramatic increase in engine protection, helping you avoid costly repairs associated with engine wear.

Ea Bypass Filters can help users extend their oil drain intervals. AMSOIL recommends using oil analysis when extending oil drain intervals.

How Bypass Filtration Works

AMSOIL spin-on bypass filter diagramBypass oil filtration features a secondary filter with the purpose of eliminating nearly all contaminants from motor oil. Bypass filters have high capacities and eliminate much smaller particles than full-flow filters, including soot. Bypass filters reduce engine wear and increase oil volume, but their high efficiencies mean they also have higher restriction and must be used in conjunction with a full-flow filter.

Bypass filters operate by filtering oil on a “partial-flow” basis. They draw approximately 10 percent of the oil pump’s capacity at any one time and trap the extremely small, wear-causing contaminants that full-flow filters can’t remove. Bypass filters have a high pressure differential, causing the oil to flow through them very slowly and allowing for the removal of smaller contaminants. It is called bypass filtration because the oil flows from the bypass filter back to the sump, bypassing the engine. This continual process eventually makes all the oil analytically clean, reduces long-term wear and can dramatically extend oil drain intervals.

Full Flow Filter vs Bypass Filter

Full-flow filters are more open and free-flowing than bypass filters so they are able to support the flow of oil that lubricates the engine. Because they are freer-flowing, they are less efficient at removing small particles. AMSOIL Ea® Full-Flow Filters can efficiently remove particles down to 20 microns.

Bypass filters only filter a small percentage of the system’s oil at any given time. Denser, more efficient filtration media provides improved small-particle removal. Ea Bypass Filters efficiently remove contaminants (98.7 percent efficiency) down to 2 microns.

Used together, full-flow and bypass filters provide comprehensive wear protection against both large and small particles, as well as both short-term and long-term wear. In addition, filter capacity is increased, and the life of the filters is extended.

AMSOIL Ea® Bypass Oil Filter

AMSOIL Ea Bypass Oil Filters provide maximum filtration protection against wear and oil degradation. Working in conjunction with the engine’s full-flow oil filter, AMSOIL Ea Bypass Filters operate by filtering oil on a “partial-flow” basis. They draw approximately 10 percent of the oil pump’s capacity at any one time and trap the extremely small, wear-causing contaminants that full-flow filters can’t remove. AMSOIL Ea Bypass Filters have an efficiency of 98.7 percent at two microns. At normal operating RPM, Ea Bypass Filters will filter all of the oil in a typical five-quart sump in less than 10 minutes. AMSOIL Ea Bypass Filters typically filter all of the oil in the system several times an hour, so the engine continuously receives analytically clean oil.

AMSOIL Bypass Filters are designed to filter out fine particles; they are not meant to extend oil change intervals beyond original recommendations. However, when fine particles are filtered out of the motor oil, it may be possible to attain longer drain intervals. This should be determined by used oil analysis. In addition, the use of an AMSOIL bypass system may allow for the use of larger oil filters, which can increase filtering capacity.

Using AMSOIL synthetic motor oil has no effect on vehicle warranties. A federal law called the Magnuson-Moss Act (1975) prevents original equipment manufacturers from putting conditions on vehicle warranties attached to any product or service identified by brand, trade or corporate name, unless the manufacturer provides that product or service free of charge. This means consumers have the freedom to use aftermarket products of their choice without fear of losing the original limited or implied vehicle warranty.
