The Importance of Engine Filtration

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

THE PROBLEMS

Engine Wear - Automotive experts agree that dirt is the number one cause of engine wear. At first glance, it does not seem possible. Engine dirt particles are so small- mere dust specs- and an engine is a highly sophisticated piece of machinery, crafted from the most durable metal alloys. How can these minute particles bring down such a high-tech giant? The answer lies in the fact that dirt particles are extremely abrasive. They consist of razor-like flakes of road dust and airborne grit drawn into the engine through the air intake, as well as manufacturing scarf and wear metal particles generated inside the engine. These particles are carried by the oil into the precision clearances between bearings and other moving parts. Once they work in between these parts, they grind and gouge surfaces, altering clearances, and generating more abrasive debris. As this wear cycle continues, precision components become progressively sloppy and fatigued until they fail altogether.

Oil Degradation - In addition to physically assaulting engine components, dirt and other contaminants work to degrade the oil that provides vital engine lubrication. Sooty particles generated during combustion can be forced past piston rings and into the oil. These particles act like tiny sponges, absorbing critical additives and shortening oil life. Soot also wreaks havoc with viscosity by causing oil to thicken. And in the presence of moisture, common by-products of combustion will react chemically to produce corrosive and rust-producing acids.

THE SOLUTION

AMSOIL Oil and Air Filters - Filtration is 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 of oil circulation. In order for filtration to be truly effective, however, it must be able to capture contaminants of all types and sizes.

AMSOIL has developed a complete line of sophisticated filtration products designed to offer the best protection available against virtually all harmful engine contaminants. With an AMSOIL 2 Stage Air Filter, an AMSOIL Duty Oil Filter and an AMSOIL By-Pass Oil Filter, your engine can run long and hard with outstanding protection against engine dirt.



AMSOIL SDF OIL FILTERS

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.

AMSOIL SDF FILTERS WORK BETTER - LONGER!

AMSOIL Super Duty Filters (SDF) feature an advanced fiber media offering the ready flow of oil hard-working engines demand with superior capacity, efficiency and service life to that offered by conventional paper oil filters. In fact, SDF has over a 75% better combined efficiency/capacity rating than other popular oil filters as tested according to the Society of Automotive Engineers industrial standards.

The AMSOIL SDF may be used for intervals of 12,500 miles or six months (whichever comes first) in gasoline engine applications.



THE AMSOIL SPIN-ON BY-PASS OIL FILTER

Absolute Protection from Engine Dirt

Assurance of Analytically Clean Oil

WHY ANOTHER FILTER? Even the best full flow-filter can't do it all.

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

But the smallest grit that passes through- road dust, manufacturing scarf, and engine metal-flake in the 5-20 micron range - accounts for up to 60% of all engine wear. These microscopic particles closely match the precision clearances between critical 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 blowby combustion product of fuel ignition, or as condensed moisture from air drawn into the engine through the air intake. Water causes metal surfaces to rust; it also reacts with other blowby 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 of 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 the 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 disc, 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.



The AMSOIL Dual-Remote Oil Filtration System- For Optimum OIL FILTRATION and Maximum SERVICE ACCESSIBILITY

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

The mount couples an 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 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 units allows larger oil filters to be used, and increases 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 25,000 miles or one year (whichever comes first) or longer if using oil analysis. The Super Duty Full Flow filter is changed at 12,500 mile or 6 month intervals (whichever comes first) for gasoline engines.

Once the Dual-Remote Filtration System is installed if you elect to use oil analysis testing then you DO NOT need to change your engine oil unless oil analysis testing results indicates you need to. Test samples are easily pulled from the dipstick tube with an AMSOIL pump into a 3 oz bottle and then put into a postage paid box mailed to Oil Analyzers Inc. This is typically performed every 20,000 miles or every year, whichever comes first for passenger vehicles and light duty trucks. You may very well travel several hundred thousands of miles without needing to change you oil when using oil analysis testing. It really is a simple process and provides an accurate analysis of your engine's internal condition. Oil analysis testing is common practice with commercial, fleets and heavy-diesel equipment that you can put to use for your benefit as well.
