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.
