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.

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.
