Provides Superior Wear Protection
AMSOIL Synthetic 20W-50 Premium
Protection Motor Oil is a high viscosity oil engineered
to protect against metal-to-metal contact. It resists viscosity
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. AMSOIL Premium
Protection Synthetic Motor Oil helps extend engine life.
Exceeds the Requirements of
Wet Clutch Transmissions
AMSOIL Premium Protection Synthetic Motor Oil contains
no friction modifiers, making it ideal for motorcycles,
maintenance equipment and other wet clutch
transmission applications. Formulated to prevent clutch
glazing and slippage, it insures smooth clutch engagement
and long term, dependable transmission operation. AMSOIL Synthetic 20W-50 Motor Oil
reduces clutch wear for extended transmission life.
Resists Oxidation and
High Temperature Breakdown
AMSOIL Premium Protection Synthetic Motor Oil overcomes
the thermal deficiencies 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 clean, promoting cooler operation and long engine life
in air or liquid cooled engines.
Extends Drain Intervals in Gasoline
and Diesel Engines
The superior AMSOIL synthetic base stock
and additive technology exceeds the
requirements of both gasoline
and diesel engines. AMSOIL
Premium Protection Motor
Oil neutralizes acids,
disperses soot and lasts
longer in service than
conventional oils.
MIXING AMSOIL
AMSOIL Synthetic 20W-50 Premium
Protection Motor Oil 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 Synthetic Oils.
SERVICE LIFE
AMSOIL Synthetic 20W-50 Premium Protection Motor Oil is recommended for extended intervals in unmodified, mechanically-sound vehicles or equipment as follows:
Diesel Engine Service
•Normal Service - Up to 25,000 miles or one year, whichever comes first, or longer based on oil analysis.
•Severe Service - Up to 15,000 miles or one year, whichever comes first, or longer based on oil analysis.
Gasoline Engine Service
•Normal Service - Up to 15,000 miles or one year, whichever comes first, or longer based on oil analysis.
•Severe Service - Up to 15,000 miles or one year, whichever comes first, or longer based on oil analysis.
Motorcycles, Small Engines, Stationary Engines, Heavy Equipment and Other Applications
•Extend drain intervals based on oil analysis or follow the manufacturer-recommended drain interval.
AMSOIL Ea™ Full-Flow Oil Filters are designed for extended drain intervals. They stop smaller particles, flow more oil and last longer than regular filters. For best performance, use AMSOIL Ea™ Full-Flow Oil Filters and replace at the time of oil change. Other oil filters should be changed at standard OEM* intervals.
