It provides outstanding performance and protection over extended drain intervals in light and heavy-duty diesel engines. Exceeds All Performance Requirements of Light and Heavy-Duty Diesel Engines. Product Code: PCO
PRODUCT DESCRIPTION
AMSOIL Synthetic Blend 15W-40 Diesel Oil is a modern blend of high performance synthetic base stocks, natural base stocks, and advanced additives. It provides outstanding performance and protection over extended drain intervals in light and heavy-duty diesel engines.
Remains Stable at Temperature Extremes
AMSOIL Synthetic Blend 15W-40 does not change viscosity (thicken or thin) at temperature extremes like conventional motor oils. With its advanced semi-synthetic formulation, AMSOIL Synthetic Blend 15W-40 is significantly more shear stable than conventional oils, retaining its viscosity at temperatures and loads that break down conventional motor oils.
Resists Oxidation - Reduces Engine Wear
Conventional oils oxidize at high temperatures, causing sludge and deposit build-up that decrease fuel efficiency, contribute to corrosion, and increase engine wear. AMSOIL Synthetic Blend 15W-40 Motor Oil resists oxidation and thermal breakdown far better than conventional oils. It continues to lubricate, cool and protect at temperatures that oxidize conventional oils. In addition, the advanced heat transfer capabilities and high lubricity of AMSOIL Synthetic Blend 15W-40 help engines run cooler with less wear.
Extended Drain Intervals
AMSOIL Synthetic Blend 15W-40 is formulated for extended drain intervals.

In fact, 12 TBN AMSOIL Synthetic Blend 15W-40 Motor Oil keeps engines in "like-new" condition even when the oil is used for extended service intervals.
Improves Cold Weather Performance
Due to their wax content, conventional oils thicken in cold temperatures and, on cold starts, may take as long as five minutes to lubricate internal engine parts. AMSOIL Synthetic Blend 15W-40 stays fluid at very low temperatures. It circulates rapidly to provide vital lubrication and prevent engine wear caused by lack of oil flow. AMSOIL Synthetic Blend 15W-40 allows quicker, easier cold temperature starting with less engine wear.
Reduces Oil Consumption
AMSOIL Synthetic Blend 15W-40 is low volatility oil. Low volatility means less oil vapor passing into the combustion chamber. A reduction of oil vapor means lower oil consumption and lower exhaust emissions. The high detergent alkalinity of AMSOIL Synthetic Blend 15W-40 also helps reduce oil consumption.
Improves Fuel Economy and Reduces Emissions
The premium quality synthetic base oil in AMSOIL Synthetic Blend 15W-40 provides a tough lubricating film on all engine parts, reducing friction and fuel consumption. Reducing fuel consumption reduces exhaust emissions.
Protects Against Rust and Corrosion

Custom-Blended For Outstanding Performance in Today's Engines
AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil is Recommended for
Applications Requiring the Following Specifications:
PRODUCT CODE:
ACB
"AMSOIL gives our equipment the best protection from wear while allowing it to start easier, run cooler and get the best fuel efficiency possible."
D.D., Brownwood, Texas
PRODUCT DESCRIPTION
AMSOIL Synthetic Heavy-Duty
Diesel and Marine Motor Oil combines the superior lubricity and performance
capabilities of a premium synthetic lubricant with special rust and corrosion
inhibitors. AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil is
recommended for engines used in marine applications, as well as diesel engines
used in trucks, fleets, mining, earth moving, construction and farm equipment.
Other applications include taxi and local delivery fleets with gasoline or
diesel engines. With its extended drain intervals, AMSOIL Synthetic Heavy-Duty
Diesel and Marine Motor Oil reduces maintenance costs, downtime and the cost of
waste oil disposal.
Provides High Shear Stability
AMSOIL Synthetic
Heavy-Duty Diesel and Marine Motor Oil surpasses the European ACEA and North
American SAE oil specifications for high temperature/high shear (HTHS)
viscosity. It is significantly more shear stable than conventional motor oils,
retaining its viscosity at temperatures and loads that break down conventional
oils. AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil maintains an
extremely protective viscosity of greater than 3.7 cP at 302°F (150°C) in the
ASTM D-4683 High Temperature/High Shear Test, exceeding the test limits.
Prevents Rust and Corrosion
AMSOIL Synthetic
Heavy-Duty Diesel and Marine Motor Oil contains special rust and
corrosion-inhibiting additives to prevent the rusting or corrosion of iron,
copper, lead and aluminum materials.
Improves Fuel Economy
The premium quality synthetic
base stocks in AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil provide a tough lubricating film on all engine parts, reducing friction and fuel
consumption. Reduced fuel consumption reduces exhaust emissions of carbon
dioxide, water and particulates.
Resists Oxidation - Reduces Engine Wear
Conventional oils oxidize at high temperatures, causing sludge and
deposit build-up that decrease fuel efficiency and contribute to corrosion and
increased engine wear. AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil,
with a flash point of 442°F (228°C), resists oxidation and thermal breakdown far
better than conventional oils. It continues to provide maximum protection at
temperatures that oxidize conventional oils. Also, the advanced heat transfer
capabilities and high lubricity of AMSOIL Synthetic Heavy-Duty Diesel and Marine
Motor Oil helps engines run cooler and reduces wear.
Extended Drain Intervals
AMSOIL Synthetic
Heavy-Duty Diesel and Marine Motor Oil is formulated for extended drain
intervals. Its unique synthetic formulation, improved detergent/dispersant
capabilities, and long drain additive package ensure maximum engine protection,
cleanliness and performance over extended drain periods. Its advanced 12 TBN
formulation keeps engines in superb condition even when the oil is used for
extended drain intervals.
Provides Low Temperature Protection
AMSOIL
Synthetic Heavy-Duty Diesel and Marine Motor Oil remains fluid at temperatures
as low as -47°F (-44°C). It circulates rapidly to provide vital lubrication and
prevent engine wear caused by lack of oil flow. AMSOIL Synthetic Heavy-Duty
Diesel and Marine Motor Oil allows quicker, easier cold temperature starting
with less engine wear.
Reduces Oil Consumption and Emissions
AMSOIL
Synthetic Heavy-Duty Diesel and Marine Motor Oil passes the NOACK Volatility
Test. Many conventional lubricants cannot pass this requirement. Low volatility
means less oil vapor passing into the combustion chamber. A reduction of oil
vapor means lower oil consumption and lower exhaust emissions. The high
detergent alkalinity of AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil
also helps reduce oil consumption.
MIXING AMSOIL
AMSOIL Synthetic Heavy-Duty Diesel
and Marine Motor Oil is compatible with conventional petroleum oils and other
synthetic oils; however, mixing AMSOIL Synthetic Heavy-Duty Diesel and Marine
Motor Oil with a conventional oil will shorten the extended drain period of
AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil. Engine oil additives or
after-market products are not recommended for use with AMSOIL Synthetic
Heavy-Duty Diesel and Marine Motor Oil.
SERVICE LIFE
Diesel engines, fleet vehicle engines
and industrial engines: drain oil at intervals up to two times longer than
recommended by the engine manufacturer or at six month intervals. Extended drain
intervals may be used if they are supported by the findings of used oil
analysis.
Personal car and light-truck non-turbocharged gasoline engines and marine craft gasoline engines: drain oil at intervals up to three times longer than those recommended by the engine manufacturer, or one year, whichever comes first.
Non-commercial, turbo charged passenger car gasoline engines: drain oil at intervals up to two times longer than those recommended by the engine manufacturer, or six months, whichever comes first.
High-performance or racing engines: drain oil at intervals determined by the findings of a used oil analysis program.
Motorcycle engines and small four-cycle gasoline engines: use engine manufacturer's oil drain recommendations.
Change AMSOIL Full Flow Oil Filters at 12,500-mile or six-month intervals, whichever comes first, in gasoline engines. In diesel engines change AMSOIL Full-Flow Oil Filter at 7,000 miles or six months, whichever comes first. Change other manufacturers' oil filters at the engine manufacturer's recommended filter change intervals.

PRODUCT DESCRIPTION
The Ea By-Pass Oil Filter (EaBP) provides the best possible filtration
protection against wear and oil degradation. Working in conjunction with
the engine’s full-flow oil filter, the AMSOIL Ea By-Pass Filter operates
by filtering oil on a “partial-flow” basis. It draws approximately 10 percent
of the oil pump’s capacity at any one time and traps the extremely
small, wear-causing contaminants that full-flow filters can’t remove. The
AMSOIL Ea Bypass Filter typically filters all the oil in the system several
times an hour, so the engine continuously receives analytically clean oil.

New Aluminum Billet Oil Fill and Oil Filter Caps for BMK21 By-Pass Filtration System
Engine compartments are becoming increasingly cramped, leaving little room for after-market additions and improvements. The BMK21 is a single remote by-pass filter system that fits into much smaller spaces than the AMSOIL Dual-Remote By-Pass System.
Ford 6.0L Power Stroke™ Diesels
Dodge 5.9L/6.7L Cummins Diesels
General Motors 6.6L Duramax Diesels The Sandwich adapter is an anodized billet aluminum adapter that screws on to the present full flow oil filter nipple located on the engine block. The full flow filter is then simply spun on to the adapter. The Sandwich adapter has an orifice to provide high-pressure oil feed for the BMK21. Like the other diesel applications, AMSOIL now offers an Aluminum Billet Oil Filler Cap for (BK1202) to ease the installation of the oil flow from the BMK11 back to the engine. To complete an installation, the following components must be purchased separately:
|
Higher Efficiency
AMSOIL EaBP Filters have an efficiency of 98.7 percent at two
microns. At normal operating RPMs the EaBP Filter will filter all of
the oil in a typical five quart sump in less than 10 minutes.
Superior Construction
The superior construction of AMSOIL EaBP Filters provides better sealing
and increased longevity along with superior corrosion resistance.
AMSOIL EaBP Filters have a marine powder coated exterior; and
their zinc-dichromate base plates increase rust protection. EaBP
Filters have a nitrile HNBR gasket and an orange silicone anti-drain
valve. The two stage pleated and layered cellulose/full synthetic
media has an efficiency rating of 98.7 percent at two microns.
Longer Lasting
When used in conjunction with AMSOIL motor oil and an AMSOIL EaO
or Donaldson Endurance™ filter, the EaBP should be changed every
other full-flow filter change up to 60,000 miles. When used with
other brands of motor oil or full-flow filters, the EaBP Filter should
be changed every other full-flow filter change. AMSOIL recommends
using oil analysis when extending oil drain intervals.
Increased Oil Capacity
The increased fluid system capacity and filtration
life provides improved oil cooling and ensures that
equipment constantly runs on clean oil. Engine efficiency
is increased, providing extended engine life.
Soot Removal
AMSOIL has designed a high-efficiency
by-pass filter element that is also a soot removal
device. AMSOIL Ea By-Pass Filters use a synthetic/cellulose sandwiched media. The inner
layer of the element is composed of a highly efficient
cellulose media covered with a full synthetic
media outer layer. These filters remove 39 percent
of soot contaminants less than one micron.
Soot removal efficiency increases approximately
10 to 14 percent when the EaBP Filter is used in conjunction with a standard full-flow filter.
By-Pass Filtration Benefits
• Dramatically Extended Drain Intervals
• Improved Oil Cooling
• Increased Filtration Capacity and Life
• Increased Fluid System Capacity
• Efficient Small Particle and Soot Removal
• Significantly Extended Engine Life
• Equipment Constantly Runs on Clean Oil
• Increased Engine Efficiency
• Remove Particles Less Than One Micro
Dual Remote Filter System
The AMSOIL Dual Remote Oil Filtration System
converts an engine’s full-flow oil filter system into
a full-flow/by-pass oil filtration system by attaching
an AMSOIL Full-Flow Oil Filter and AMSOIL
Spin-On By-Pass Oil Filter onto a remote mount.
The Dual Remote System provides superior filtration efficiency, increased oil capacity and
improved oil filtration accessibility. See the G1092 brochure for more info on the Dual Remote Filtration System.

A. Getting started 2. Make sure you have the tools needed for the job. Recommended tool list
5/16" Allen wrench 3. Because of the wide range of possible mounting configurations, hose and hose fittings are not provided with this mount. Hose should meet or exceed SAE-100R6 specifications, and have a minimum inside diameter of 1/4". The mount itself has 3/4"-16 straight threads and the adapter fittings provided are 3/4"-16 straight x 1/4" JIC. Read through instructions and determine which plumbing arrangement best fits your application. Purchase hose and fittings according Make certain hose fittings match the type of hose chosen. Note: Hose and hose fittings are available from AMSOIL and your local AMSOIL Dealer. Refer to diagram D below and the parts list for 1/4" components matched for use with this system. |

|
B. Filter selection
Service recommendations for these filters are listed later in these instructions. Selecting a larger filter than recommended will extend the service interval, while selecting a smaller filter than recommended will shorten the service interval. C. Attaching the filter mount 1. Survey the engine compartment for possible mounting locations. Solid structures such as the firewall, fender well, radiator support or frame are normal locations. Refer to diagram A for minimum area requirements and consider accessibility for servicing. 2. Note that the filter mount can be rotated 180° in its mounting brackets. This allows the oil supply and return hoses to enter the mount on either the right of left hand side. Choose the side that will minimize the need for bends in the hoses or additional hose fittings. Refer to diagram B for preferred mounting positions. 3. When the location has been determined, use the mounting template provided to locate and mark mounting holes. This can be easily done with a center punch and hammer. 4. With a 1/4" drill bit, drill out the previously marked mounting holes and attach the two piece mount bracket. Use the 4 -1" long 1/4" bolts, nuts, small washer and fender washers provided. Note the assembly diagram D for details. Using two 7/16" wrenches or socket, tighten to 8 foot pounds.
5. Apply thread sealant onto the "0" ring adapter fitting (BP-213) and the restriction assembly (BP-202) as noted in diagram C. Install the "0" ring adapter fitting (BP-213) in the mount end adjacent to the arrows pointing IN. Install the restriction assembly (BP-202) in the mount end adjacent to the arrow pointing OUT. Using a 7/8" wrench, tighten both fittings to 40-43 foot pounds. 6. Apply thread sealant as noted indiagram C to the Allen head "0" ring plugs (BP-191). Using a 5/16" Allen head wrench, install plugs in remaining mount ports and tighten to 40-43 foot pounds. Note: If optional oil sampling valve is to be used, refer to diagram D and install in place of either Allen head "0" ring plug. 7. Attach the filter mount to the mounting brackets using 4 - 1-1/2" long 1/4" bolts, nuts and washers provided. Warning: The bolts must be installed so that the nuts are on the side opposite the filter nipples. Failure to do this will result in the bolts hitting the oil filters. Using two 7/16" wrenches or socket, tighten to 8 foot pounds.
D. Oil Supply 2. An alternate installation is to use the existing oil pressure sending unit. Remove the oil pressure sending unit and install a street tee. Then re-install the sending unit in one arm of the tee. Note: With this installation a slightly lower oil pressure reading may register, indicating oil flow to the by-pass filter. A change of 10% or less is not to be considered significant. 3. Install selected hose and hose fittings between the engine block or the remaining arm of the tee and the filter mount port marked with the arrow pointing IN. Hose should be routed in a manner that avoids contact with sharp or moving parts and minimizes bends. If bends in the hose can not be avoided, make sure the bend is greater than the minimum radius recommended by the hose manufacturer. Note: Bends should not start at the fitting. Refer to diagram E for suggestions on proper hose routing. 4. To maintain hose position, plastic hose ties are advised.
E. Oil Return 2. New Porting Option: Where an installation requires a new hole (in oil pan or valve cover), a self-tapping hollow bolt may be used. (The bolt is available from AMSOIL. Order BP-40 Bolt and BP-41 Sealing Gasket.) Note: The self-tapping hollow bolt should be used on stamped metal components only.
3. Other Options: Use a hollow bolt (available locally) to replace a cap screw holding such components as the fuel pump, timing case, or an inspection cover. Remove the selected bolt and determine if it provides an unrestricted passage to the oil pan. If so, install the hollow bolt. Route and connect hose as previously described. You may also use the AMSOIL Oil Return Swivel fitting (BP-89). See additional information on swivel fitting below. 4. Fill the selected AMSOIL By-Pass Filter elements with the same motor oil being used in the vehicle. Lubricate the filter gasket with oil and spin filters onto mount. Tighten one full turn after filter gasket first contacts mount, back off 1/8".
F. Start up procedures 2. Check engine oil level. Fill to full mark if necessary.
3. Set vehicle parking brake. With transmission in park/neutral start the engine and immediately check oil pressure. Note: Pressure may initially take a moment or two to rise. 4. After engine has warmed, shut off and re-check engine oil level. Fill as necessary. 5. Record vehicle mileage/operating hours and date of installation.
G. Periodic maintenance 2. Properly sized, your AMSOIL By-Pass filters will last twice as long as your regular full-flow filters. It is recommended however, filters be changed using an oil analysis program. 3. To change the filter elements:
