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.
