AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil provides the ultimate in diesel engine protection. Specifically formulated for long-life, it resists oxidation and thermal breakdown, retains viscosity and eliminates sludge and varnish formation. Outstanding lubricity provides unbeatable wear protection and maximum fuel efficiency. It contains special performance additives for acid and soot control. Extended drain capability reduces downtime and oil expenses.
AMSOIL Formula 4-Stroke Synthetic 0W-40 Motor Oil is specially formulated to provide serious protection and performance in recreational four-stroke outboard motors. Its broad 0W-40 viscosity rating provides superior protection in both hot and cold temperature extremes. It provides superior shear stability and resistance to vaporization so engine wear, oil consumption, friction, heat and emissions are kept to an absolute minimum.
AMSOIL Marine Dual Remote Filtration System (BMK-18)
Hard-working engines come in all shapes and sizes, from heavy-duty diesels
to high performance racing engines. Though seldom recognized as part of
this group, marine engines include some of the hardest working, hottest
running engines out there.Marine engines, from those found in recreational watercraft to larger commercial boats, often sit idle in storage for weeks or months and when put on the water are required to run at full throttle for extended periods of time. These torturous conditions place tremendous stress on engines and engine oils. Since clean engine oil is critical for ensuring proper operation and protection, AMSOIL recommends the use of the Marine Dual Remote Filtration System (BMK-18). PDF
The AMSOIL Dual Remote and By-Pass filtration systems have been an integral part of the company's advanced engine protection product line. Building on the customer-proven success of auto- motive dual remote and by-pass filtration technology, the Marine Dual Remote Filtration System was created to address the specific severe operating environment of marine engines in both salt and fresh water. For example, the hoses are U.S. Coast Guard approved, the fasteners and the mounting brackets on the BMK-18 are stainless steel and the connectors are aluminum making them significantly corrosion resistant. Specifically designed for recreational and light commercial marine applications that use in both or inboard/outboard stern drive engines, the Marine Dual Remote Filtration system offers easily accessible remote mounting capability for a full flow spin-on oil filter and a spin-on style by-pass oil filter. This unique combination of both full flow and by-pass filtration on a single mounting manifold is the only system of this kind designed specifically for marine applications.
The effects of marine engines running predominantly at or near full throttle after extended periods of non- activity include high operating temperatures and increased potential for wear on engine components. The AMSOIL Marine Dual Remote Filtration System offers a clear advantage by providing better oil filtration, increased oil capacity, longer oil and filter life, plus the ability to remove moisture and condensation from the lubrication system. Moisture typically condenses inside engines to combine with residual combustion gases. The resulting compounds strip beneficial additives from engine oil and act as corrosive substances that further degrade the engine oil and promote engine wear. Humid environments make marine engines especially prone to these conditions. The BMK-18 greatly curbs the effects of moisture and condensation by safely retaining water within the filtration system.
Dual remote filtration is a highly efficient filtering process capable of removing the vast majority of wear causing particles which are in the 5-20 micron range. It also has the ability to remove particles down to 1 micron in size. Furthermore, a dual remote filtration system requires a 1.5 to 2 quart oil volume increase, with the added oil offering increased cooling capabilities. The additional hoses, fittings, filters and aluminum mount assemblies also allow the engine oil to dissipate heat more efficiently as it passes through the filtration system, extending the life of both the engine and the engine oil.
A large number of marine diesel engines have by-pass oil filtration
systems installed by the engine manufacturer. Until now, however, this technology has not been available to smaller pleasure boats and light
commercial marine applications.
Depending on the owner's frequency of use, the improved filtration of the Marine Dual Remote system, along with the use of AMSOIL synthetic lubricants, could completely eliminate oil and filter changes during a typical boating season.
With marine engines located in a relatively confined and remote space within the watercraft, ease of filter access and-reduced oil spillage are significant benefits of the Marine Dual Remote System.
The BMK-18 is packaged in kit form, which includes the Dual Filter mount, mounting hard- ware, hoses, hose fittings, component parts and installation instructions. In addition, adapter kits of four different sizes enable the BMK-18 to be installed on a wide variety of recreational and light commercial marine engines.
The AMSOIL Marine Dual Remote Filtration System represents the cutting edge of filtration technology-another example of the
company's commitment to providing quality innovations that can benefit consumers everywhere.

Four-stroke
gasoline engines have long been a mainstay of the general marine industry.
They have succeeded in reducing emissions and increasing fuel efficiency,
and they have also been a hit with consumers. In fact, Mercury Marine has
seen its four-stroke outboard sales surpass its two-stroke sales. When
four-stroke outboard motors were introduced to the market, manufacturers
recommended either their own specially formulated oil or an API SG or SL
automotive oil. However, because the specific lubrication requirements of
automobiles and outboard motors are different, it soon became apparent
that four-stroke outboard motors would require their own oil
specification. This standard, entitled FC-W, was released by the National
Marine Manufacturers Association (NMMA) in August 2004.

Marine
engines operate under high loads and RPMs for extended periods of time,
causing traditional automotive oils to break down and lose viscosity.
While automobile engines normally operate at around 2,500 rpm, outboard
motors can run twice as fast, requiring greater levels of wear protection
and better bearing durability than automobiles. In addition, prolonged
idling and low operating temperatures contribute to fuel dilution, further
thinning the oil. To ensure adequate protection for their engines, marine
engine manufacturers set minimum high temperature/high shear (HTHS)
viscosity limits. AMSOIL Formula 4-Stroke®
