Spin-On By-Pass Oil Filter

    Why another filter?

 

 Even the best full-flow filter can't do it all.  Any full-flow filter must allow oil to pass through quickly to keep the engine starving for oil.  advances in auto technology and more compact engine designs place increasing demands on these filters; to keep from creating a bottleneck they filter out only the coarser particles, and feature relief valves that open when the engine's demand for lubrication can't be ignored.

Approximately 60 percent of all engine wear is caused by dirt particles in the 5 to 20 micron range. These particles can get inside the precision clearances between engine components and cause severe damage. While full-flow oil filters generally stop contaminants no smaller than 25 to 40 microns, the AMSOIL By-Pass Filter effectively stops particles smaller than one micron in size, substantially reducing engine wear.

  But the smallest grit that passes through― road dust, manufacturing scarf, and engine-metal flake in the 5 to 20 micron range― accounts for up to 60 percent of all engine wear.  These microscopic particles closely match the precision clearances between engine components; they can enter the spaces between bearings, rings, and other components, to damage metal surfaces, altering tolerances, fatiguing components, and generating additional debris.

    Automobile engines are also susceptible to damage related to water formation, something a full-flow filter is powerless against.  Water enters the oil either as a blow-by combustion product of fuel ignition, or as condensed moisture from air drawn into the engine through the carburetor.  Water cause metal surfaces to rust; it also reacts with other blow-by contaminants to produce corrosive acids that attack the engine, contributing to further friction, wear, debris, and oil degradation.

The AMSOIL Solution ― By-Pass Filtration

    Unlike a full-flow filter, the AMSOIL By-Pass Filter is situated outside the main line of oil circulation; it taps into the line to bleed off and clean only a portion of the oil at a time.  The AMSOIL By-Pass Filter retains the oil longer and does a more thorough job of removing contaminants without obstructing flow.  You still need a full-flow filter, of course, because oil must circulate continuously.  But with an AMSOIL By-Pass Filter drawing 10% of your system's capacity, all the oil in a six-quart system will be filtered to analytical purity in about five minutes, at an average engine speed equivalent to 45 mph.

    The differences between AMSOIL By-Pass Filters and others are the unique design of the filtering media and the patented construction of the filter element.  Our high-capacity filtration medium is a special blend of virgin wood and cotton fibers, formed into discs, stacked, and compressed.  The center tube is all-steel, perforated for oil flow, and wrapped with a fine mesh cotton screen.  All dirt particles down to one-tenth of a micron  in size are trapped, and the medium's thirsty cellulose fibers can remove up to a pint of water.  Channeling is eliminated with the inclusion of a hydraulic follower plate activated by a sophisticated internal pressure system.

    Each filter consists of a mounting unit with a spin-on filtering cartridge, connected by hoses to the engine ports as illustrated.  The entire assembly is less bulky than other by-pass systems, and fits easily into cramped engine compartments.  Changing the spin-on filter is simple... no more soggy, dripping elements sliding out of tilted canisters.

Reduces Wear

Approximately 60 percent of all engine wear is caused by dirt particles in the 5 to 20 micron range. These particles can get inside the precision clearances between engine components and cause severe damage. While full-flow oil filters generally stop contaminants no smaller than 25 to 40 microns, the AMSOIL By-Pass Filter effectively stops particles smaller than one micron in size, substantially reducing engine wear.

Prevents Oil Degradation, Rust and Corrosion

Water enters motor oil as a combustion by-product or as a condensate. Water contamination of the motor oil can cause extreme engine damage. Water causes metal surface rust and corrosion, which increases friction and wear and deteriorates the close-fitting tolerances between engine components. In addition, water reacts with other oil contaminants to form corrosive acids, which also damage metal components. The AMSOIL By-Pass Filter removes water, reducing the risk of oil degradation, engine rust and corrosion.

Extends Oil Drain Intervals

Because the AMSOIL By-Pass Oil Filter removes water and particles smaller than one micron, it significantly increases the time oil can safely be left in the engine. In fact , engines using AMSOIL Synthetic Motor Oil and an AMSOIL By-Pass Oil Filter routinely show much lower rates of engine wear - even when the oil is used for significantly longer drain intervals - than engines using conventional products and conventional oil drain intervals. That saves motorists time and money and helps protect the environment by creating substantially less used oil.

 

The AMSOIL Dual Remote Oil Filtration System

    The AMSOIL Dual Remote Oil Filtration System replaces the standard full-flow filter with a combination full-flow/by-pass system, using a remote mounting assembly.

The mount couples as AMSOIL Full-Flow Oil Filter with an AMSOIL Spin-On By-Pass Filter; it takes oil from the engine and returns it without the use of multiple fittings or extra return holes in the oil pan or valve cover.  The mount and filters are installed in an accessible area of the engine compartment.

A specially-manufactured, spin-on steel casting with threading adapters is simply screwed onto the engine block's filter nipple, replacing the old full-flow filter.  In-and-out ports in the casting and two flexible oil lines connect this adapter to the remote mount.

Remote placement of the filtration unit allows larger oil filters to be used, and increases oil sump capacity ― dramatically extending the oil's useful service life and protecting your wise investment in AMSOIL Synthetic Motor Oil.  The recommended replacement interval for the AMSOIL By-Pass Oil Filter is 25,00 miles or one year (whichever comes first).

 

 

DUAL GARD By-Pass Oil Filtration System

    The AMSOIL Dual Gard By-Pass Oil Filtration System treats oil to ultra fine filtration, which increases engine and oil life and enhances engine performance.

By-Pass Filter elements remove submicron sized particles, keeping oil analytically clean.  Clean oil lubricates and cools efficiently because its coefficient of friction is low.  It promotes superior piston ring seal, which improves compression and engine power, and reduces blow-by, oil consumption and fuel dilution.  Oil lasts longer when clean, since its additives are not consumed by contaminant control.

    By-Pass Filter elements also remove water.  Water removal inhibits the formation of acids, rust and sludge.

    The Dual Gard system allows the installation of two AMSOIL Spin-On By-Pass Oil Filter elements, which doubles the by-pass filter change intervals.  The system also makes room for a larger volume of lubricating oil, which allows the oil to run cooler and rest more.  Both increase oil durability.
