Additives

AMSOIL provides top-quality fuel additives for gasoline and diesel applications.

P.i. Performance Improver Concentrate (API)
Performance Improver Gasoline Additive (API) dissolves and removes fuel system deposits and other contaminants for improved power and overall performance in fuel injected and carbureted gasoline engines. AMSOIL PI also reduces PCV and EGR system deposits, reduces exhaust emissions and improves engine starting, idling and response. Not for use in two-stroke engines.

Gasoline Stabilizer (AST)
Gasoline Stabilizer (AST) keeps gasoline and diesel fuel from oxidizing and deteriorating, prolonging its storage life. Gasoline Stabilizer inhibits the formation of varnish and gum, which helps prevent poor injector and engine performance.

AMSOIL Engine Fogging Oil’s (FOG)
AMSOIL Engine Fogging Oil’s (FOG) superior film retention provides stored equipment with long-term protection against corrosion and dry starts, extending engine life and reducing operating expenses. Its aerosol spray formulation offers easy and clean application, while reaching more components and offering complete distribution of the oil, something especially beneficial in applications with horizontal cylinder orientation such as outboard motors.

AMSOIL Ea By-Pass Filters (EaBP) 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 Ea Oil Filters (EaO) offer superior filtering efficiency and life to that
offered by conventional full-flow oil filters. Ea Oil Filters feature advanced fullsynthetic 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.

Marine Dual Remote Filtration System
(BMK-18) 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 engineharming
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.
