NMMA Registration #FB-30010B 10W-40


Superior Protection Against Engine Wear

Marine engines operate under high loads and RPMs for extended periods of time, causing traditional automotive oils to break down and lose viscosity. To ensure good protection, the NMMA set minimum shear stability requirements for FC-W. AMSOIL Formula 4-Stroke® Marine Synthetic Motor Oil greatly exceeds the FC-W shear stability requirements, outperforming competitive oils to deliver a superior lubricating film. Formula 4-Stroke® Synthetic Oil also contains robust anti-wear additives that further reduce wear in metal-to-metal contact regions (see Four-Ball Wear Test graph).



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® Marine Synthetic Motor Oils are shear stable and formulated with sophisticated oil additive chemistry, exceeding the HTHS requirements of both the API and NMMA FC-W (see graph).





Excellent Anti-Rust Performance
Marine engines are prone to rust, leading to uncontrolled wear and premature engine failure. However, good rust protection is not natural to engine oil. It comes only by design. Formula 4-Stroke® Marine Synthetic Motor Oil is fortified with a special anti-rust agent, even more than required to pass stringent NMMA FC-W anti-rust testing.

Applications
AMSOIL Formula 4-Stroke® Marine Synthetic 10W-40 Motor Oil (WCF) is recommended for gasoline fueled four-stroke outboard, inboard, inboard/outboard (I/O) and personal watercraft motors.

BMK18 Marine By-Pass Filtration System
The BMK18 is packaged in kit form, which includes the Dual filter mount, mounting hardware, hoses, hose fittings, component parts and installation instructions. In addition, adapter kits of four different sizes enable the BMK18 to be installed on a wide variety of recreational and light commercial marine engines.

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).

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 automotive 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 hose fittings are coated with a 3 ml layer of Alumiplate™ and 1 ml of zinc and yellow chromate. Standard hydraulic fittings typically survive for 96 hours in the grueling ASTM B-117 Salt Spray Test. When we subjected the Alumiplate™ coated AMSOIL Marine Bypass System fittings to this critical corrosion resistance test protocol, they lasted over 1,000 hours! This means the Alumiplate™ coating on the fittings of the AMSOIL Marine Bypass Filtration System are 10 times more corrosion resistant than standard zinc and yellow chromate plated fittings. While this exclusive Alumiplate™ coating process is expensive, AMSOIL felt this extra margin of system protection was absolutely necessary to provide marine application customers with extraordinary corrosion resistance and protection - and the peace of mind that goes with knowing that the AMSOIL Marine Bypass System is engineered for demanding marine applications. Also, the fasteners and mounting bracket are stainless steel, and the hose are U.S. Coast Guard approved.

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 water 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 effectively 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 service 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's 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 remote mount of the BMK-18 is also compatible with the new AMS-Oiler™ Oil Precharger for added engine protection during the frequent dry starting that is typical of marine engines that sit idle for even short periods of time.

The BMK-18 is packaged in kit form, which includes the Dual filter mount, mounting hardware, 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 BMK-18 kit offers a new heavy duty, machined aluminum adapter and retaining nut that fits on the existing oil filter mount. Each adapter kit is application specific and must be ordered separately.

Also, for ease of installation in some applications, optional 90 degree fittings (BK-199 and BK-200) can be mounted on the filter adapter collar. These parts are also sold separately.

The AMSOIL Marine Dual Remote Filtration System represents the cutting edge of filtration technology-another example of AMSOIL's commitment to providing quality innovations that can benefit consumers everywhere.
