PRODUCT DESCRIPTION AMSOIL
Synthetic Blend 15W-40 Heavy Duty Motor Oil (PCO) features a dual-base of premium synthetic and
hydro-processed base oils in formulation with proven high quality anti-wear additives. This
multi-use oil is designed for both heavy-duty diesel engines (including modern EGR units) and
gasoline engines, combining versatility and heavy-duty engine protection into one cost effective
motor oil. It is formulated with high levels of dispersant and detergent additives that effectively
control acids and soot thickening to prevent corrosion, wear and deposits. AMSOIL Synthetic Blend
15W-40 Heavy Duty Motor Oil is excellent for all season use in on- or off-road
applications.
Maximizes Fuel Economy, Minimizes Oil
Consumption and Emissions
The synthetic base oil component in AMSOIL PCO reduces oil volatility (burn-off). Less make-up oil
is required to replace volatilized oil and less oil vapor gets into the exhaust stream. Oil
viscosity increase is controlled, which minimizes drag for better efficiency.
Improved Extreme Temperature
Performance
Unlike other semi-synthetic oils, AMSOIL PCO contains a high content of quality synthetic oils for
enhanced performance. Heat and oxidation resistance are improved for clean engine operation and
long lasting engine oil service life. Dependable cold-temperature flow is assured for easier
start-up and improved post start-up protection.
Bid Appropriate
AMSOIL Synthetic Blend 15W-40 fulfills the requirements of most public and private purchasing bids.
It is API CI-4 Plus/SL, Detroit Diesel PowerGuard 93K214 and Mack EO-N Premium Plus '03 registered,
making it ideal where these registrations are required.
• Licensed specifications
• Versatile for mixed fleets

MIXING AMSOIL
AMSOIL PCO is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with
other oils, however, will shorten the oil life expectancy and reduce the performance benefits.
AMSOIL does not support extended drain intervals where oils have been mixed.
Aftermarket oil additives are not
recommended for use with AMSOIL motor oils.
SERVICE LIFE
AMSOIL Synthetic Blend 15W-40 Heavy Duty Motor Oil is recommended for use according to the longest
service interval established by the engine, vehicle or equipment manufacturer. Drain intervals may
be extended based on oil analysis.
AMSOIL Ea™ full flow and Donaldson Endurance™ oil filters are
designed for extended drain intervals. They capture more wear-causing particles, have less
restriction and last longer than regular filters. For best performance, use AMSOIL Ea full-flow or
Donaldson Endurance oil filters.
HEALTH & SAFETY
This product is not expected to cause health concerns when used for the intended application and
according to the recommendations in the Material Safety Data Sheet (MSDS). An MSDS is available
upon request at 715- 392-7101 or via the Internet on the AMSOIL website. Keep Out of Reach of Children. Don't
pollute. Return used oil to collection centers.
