AMSOIL Oil and Air Filters


Ea Oil Filters 

AMSOIL Ea Oil Filters offer superior filtering efficiency and life to that offered by conventional full-flow oil filters. Ea Oil Filters feature advanced full-synthetic nanofiber technology, making them the highest efficiency filters available. The smaller fibers in synthetic media also have a controlled size and shape. This results in greater efficiency and capacity than cellulose filters, as well as better durability. AMSOIL Ea Oil Filters provide a higher level of engine protection, as well as extended filter change intervals. Extensive testing shows that AMSOIL Ea Oil Filters achieve a near-perfect absolute efficiency rating. The exclusive new technology used in AMSOIL EaO Filters provides filtering efficiency to 98.7 percent at 15 microns. Higher filtering efficiency leads to longer engine life.

AMSOIL Ea By-Pass Filters 

AMSOIL Ea By-Pass Filters are high efficiency by-pass filters that also remove soot. AMSOIL EaBP Filters have an efficiency of 98.7 percent at two microns and remove 39 percent of soot contaminants less than one micron. At normal operating RPMs the EaBP Filter will filter all of the oil in a typical five quart sump in less than 10 minutes. The superior construction of AMSOIL EaBP Filters provides better sealing and increased longevity. To increase corrosion resistance, AMSOIL EaBP Filters have a marine powder coated exterior with zinc-dichromate treated base plates. EaBP Filters have a nitrile HNBR gasket and an orange silicone anti-drain valve. The media is comprised of a two stage pleated and layered cellulose/full-synthetic composite. By-pass filtration is a valuable commodity for anyone that wants to extend drain intervals and prolong engine life. It is also beneficial to engines that are exposed to high levels of con­taminants on a regular basis.

AMSOIL Marine Dual Remote Filtration System

AMSOIL’s Marine Dual Remote Filtration System pairs an AMSOIL Full-Flow EaO Oil Filter with an AMSOIL EaBP By-Pass Filter, providing the superior soot and small-particle capture of by-pass filtration and top-quality full-flow filtration on a single mounting manifold. It is the only system of this kind designed specifically for marine applications.

The Marine Dual Remote Filtration System increases the volume of oil in engine circulation, especially when the largest possible filters are installed in the system. Increased oil capacity increases oil life, helps optimize engine operating temperatures and enhances engine life. The BMK-18 by-pass filter has the ability to remove small engine harming particles and soot from the lubrication system.

The Marine Dual Remote Filtration System is designed to be used in harsh marine environments. The hose fittings are coated with a 3 ml layer of Alumiplate and 1 ml of zinc and yellow chromate. This Alumiplate coating is 10 times more corrosion resistant than standard zinc and yellow chromate plated fittings. Further, the fasteners and mounting bracket are stainless steel and the hoses are U.S. Coast Guard approved. With the use of AMSOIL motor oils, the Marine Dual Remote Oil Filtration System and a regular program of used oil analysis and filter changes, oil changes may be much less frequent in inboard marine engines.

AMSOIL Fogging Oil & Gasoline Stabilizer


Engine Fogging Oil

Two and four-stroke motorcycles are commonly operated seasonally or infrequently, and then stored for long periods of time. During these periods of inactivity, and as a result of fluctuations in ambient temperatures, water vapor can form condensate within the engine, eventually becoming surface corrosion on cylinder liners, piston rings, anti-friction bearings and steel/iron contact surfaces on rotation seals. 

AMSOIL Engine Fogging Oil offers superior film retention, providing long-term protection against corrosion and dry starts, extending engine life and reducing operating expenses. Its aerosol spray formulation offers easy and clean applications, while reaching more components and offering better distribution than straight motor oil.

Gasoline Stabilizer

It is difficult to drain all of the fuel from equipment before storage, and doing so would expose the system to other problems, including the formation of rust and corrosion on the bare metal in the tank and fuel system and drying and cracking of gaskets and seals. Some fuels are pre-treated with oxidation inhibitors that allow them to be stored for short periods without forming excessive deposits, while other fuels have no inhibitors at all. 

AMSOIL Gasoline Stabilizer extending engine life and reducing operating reduces the oxidation process that occurs when fuel is stored for extended periods. It prevents the formation of var­nish and sludge which can clog injectors, stick floats and cause poor engine performance. AMSOIL Gasoline Sta­bilizer is ideal for stored seasonal equipment such as motorcycles, snowmobiles, lawnmowers and boats. The treat rate is one ounce with every 2.5 gallons of fuel. One bottle treats 40 gallons.
