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. It is
ideal for high mileage vehicles
with flat-tappet cams and
high-stress vehicles subject to hot
temperatures, heavy hauling,
trailer pulling or off road use.
AMSOIL Premium Protection Oil
resists oxidation, neutralizes
acids, inhibits corrosion, reduces
wear and protects against deposits.
It provides the extra anti-wear
protection required by engines with
flat-tappet cams and high-tension
valve springs. AMSOIL Synthetic
20W-50 Premium Protection Motor Oil
offers 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 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.
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...
- ISO-L-EMA
- JASO MA
(Motorcycle)
- Cummins 20071, 20072,
20076, 20077
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.
