PRODUCT DESCRIPTION
AMSOIL Synthetic 20W-50 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 a superior high-zinc additive package, 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, 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 oil 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 helps insure 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 is
specifically formulated to overcome 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 cleaner, promoting cooler
operation and long engine life in air- or liquid-cooled
engines. In addition, the higher viscosity nature of
AMSOIL Synthetic 20W-50 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
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, SJ, SH, SG
- API CI-4 Plus, CH-4, CF, CF-2
- ISO-L-EMA • Caterpillar ECF-1
- JASO MA (Motorcycle) • MAN 271/3275 • MTU
Type 2
- Cummins 20071/20072/20076/20077 • VDS-2, VDS
- Mack EO-M+ • ACEA A3/B3, E3, E5 • MB 228.3,
229.1
- Detroit Diesel 93K214
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.
