PRODUCT
DESCRIPTION
AMSOIL Synthetic 20W-50
Premium Protection Motor Oil is specially formulated to provide
superior protection and performance in a wide variety of demanding
applications. By incorporating high quality synthetic base stocks
and additives, AMSOIL Premium Protection Oil exceeds the needs of
large and small gasoline or diesel engines in cars, motorcycles,
trucks, motor homes, maintenance equipment, heavy equipment, street
rods and marine applications. AMSOIL Premium Protection Oil resists
oxidation, neutralizes acids, inhibits corrosion, reduces wear and
protects against deposits. It is ideal for high mileage vehicles and
high-stress vehicles subject to hot temperatures, heavy hauling,
trailer pulling or off road use. AMSOIL Synthetic 20W-50 Premium
Protection Motor Oil provides flexibility and performance beyond
conventional oils for convenience and trouble free operation.
AMSOIL, the
leader in automotive synthetic lubrication, produced the world’s
first API qualified synthetic motor oil in 1972. Trust the extensive
experience of AMSOIL The First in Synthetics® to do the best job
protecting your engine.
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 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.
APPLICATIONS
AMSOIL Synthetic 20W-50
Premium Protection Motor Oil is a multi-use, premium synthetic
lubricant for applications that require or benefit from a higher
viscosity oil. It is recommended for air and liquid cooled, large or
small gasoline and diesel engines, transmissions and chaincase
applications where 20W-50 oil is required with any of the following
specifications:
- API SL/CF, CI-4 Plus
- API SJ, SH, SG...
- MIL-PRF-2104G
- JASO MA (Motorcycle)
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 use up to 15,000
miles or one year, whichever comes first, in unmodified(1),
mechanically sound(2)
automotive gasoline or diesel engines. In 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.
*OEM - Original
Equipment Manufacturer
(1) Engines operating under modified
conditions are excluded from extended drain recommendations.
Examples include the use of performance computer chips; non-OEM
approved exhaust, fuel or air induction systems; and the use of
fuels other than those recommended
for normal operation by the manufacturer.
(2) Mechanically sound engines are in
good working condition and do not, for example, leak oil or consume
excessive amounts, are not worn out, do not overheat, do not leak
anti-freeze and have properly working emission control systems.
AMSOIL recommends repairing malfunctioning engines prior to the
installation of AMSOIL synthetic oils.
