Premium Protection Synthetic Motor Oil
AMSOIL Premium Protection Synthetic Motor Oil is formulated to provide superior protection and
performance in a wide variety of demanding applications. Its unique combination of synthetic base
oils and a superior additive package results in a formulation that exceeds the requirements of most
gasoline or diesel applications that call for 10W-40 or 20W-50 motor oil. Premium Protection
Synthetic Motor Oil is ideal for high-mileage vehicles and high-stress vehicles subject to hot
temperatures, heavy hauling, trailer pulling or off-road use. It provides the extra anti-wear
protection required by engines with flat-tappet cams and high-tension valve springs. AMSOIL Premium
Protection Synthetic Motor Oil offers flexibility and performance beyond conventional oils.
High-zinc formula guards against wear
Ideal for flat-tappet cams
Resists deposits to help keep engines clean
Convenience of use for gas and diesel engines
Wet-Clutch Compatible
Resists Oxidation and High-Temperature Breakdown
“75 percent more engine protection against horsepower loss and wear than required by the industry standard, extending the life of vital components like pistons and cams.”
Advanced Motor Oil Technology
AMSOIL
Superior Wear Protection
Premium Protection Synthetic Motor Oil is high-viscosity oil engineered to protect
against metal-to-metal contact. It resists viscosity loss due to shear and is formulated with a
heavy treatment of zinc and other anti-wear additives for excellent protection of gears, bearings,
cam lobes and other high-pressure components in engines and transmissions. Premium Protection
Synthetic Motor Oil helps extend equipment life.
Wet-Clutch Compatible
Premium Protection Synthetic Motor Oil contains no friction modifiers, making it ideal for
motorcycles, maintenance equipment and other wet-clutch transmission applica- tions. Formulated to
prevent clutch glazing and slippage, it helps ensure smooth clutch engagement and long-term,
dependable transmission operation. Premium Protection
Synthetic Motor Oil reduces clutch wear for extended transmission life.
Resists Oxidation and High-Temperature Breakdown
Premium Protection Synthetic Motor Oil is formulated to overcome the thermal deficien- cies common
to conventional petroleum oils. Volatilization (burn-off), oxidation and excessive deposit
formation from high heat are greatly reduced. Viscosity thickening is controlled and engines run
cleaner, promoting cooler operation and long engine life in air- or liquid-cooled engines. In
addition, the higher viscosity of AMSOIL 20W-50 Syn- thetic Motor Oil may help reduce motor oil
consumption in equipment that experiences
higher-than-normal usage rates when lower-viscosity lubricants are installed.
Extends Drain Intervals in Gasoline and Diesel Engines
Superior synthetic base oil and additive technology exceeds the requirements of both gasoline and
diesel engines. Premium Protection Motor Oil is designed to
neutralize acids, disperse soot and last longer in service than conventional oils.
COMPATIBILITY
APremium Protection Synthetic Motor Oil is compatible with synthetic and conventional motor oils.
Mixing AMSOIL motor oil with other oils, however, will shorten the oil’s life expectancy
and reduce its performance benefits. AMSOIL does not support extended drain intervals where oils
have been mixed.
Aftermarket oil additives are not recommended for use with
AMSOIL synthetic motor oils.
