AMSOIL Premium Protection Synthetic Motor Oil is formulated to
provide superior protection and performance in a wide variety of
demanding applications. Its unique combination of synthetic base oils
and a superior additive package results in a formulation that exceeds
the requirements of most gasoline or diesel applications that call for
10W-40 or 20W-50 motor oil. Premium Protection Synthetic Motor Oil is
ideal for high-mileage vehicles and high-stress vehicles subject to hot
temperatures, heavy hauling, trailer pulling or off-road use. It provides
the extra anti-wear protection required by engines with flat-tappet cams
and high-tension valve springs. AMSOIL Premium Protection Synthetic
Motor Oil offers flexibility and performance beyond conventional oils.
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
- High-zinc formula guards
- Ideal for flat-tappet cams
- Resists deposits to help
keep engines clean
- Convenience of use for gas
and diesel engines
Superior Wear Protection
Premium Protection Synthetic Motor Oil is high-viscosity oil engineered to protect
against metal-to-metal contact. It resists viscosity loss due to 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. Premium Protection Synthetic Motor Oil helps extend equipment life.
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 ensure smooth clutch
engagement and long-term, dependable transmission operation. Premium Protection
Synthetic Motor Oil reduces clutch wear for extended transmission life.
Resists Oxidation and
Premium Protection Synthetic Motor Oil is 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 of AMSOIL 20W-50 Synthetic
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
Superior synthetic base oil and additive technology exceeds the requirements of
both gasoline and diesel engines. Premium Protection Motor Oil is designed to
neutralize acids, disperse soot and last longer in service than conventional oils.
AMSOIL Premium Protection Synthetic Motor Oil is recommended
for air- and liquid-cooled, large or small gasoline and diesel
engines, transmissions and chaincase applications where
10W-40 oils are required with any of the following
- API SL, SJ, SH, SG
- API CI-4+, CI-4, CH-4, CF, CF-2
- Caterpillar* ECF-1
- JASO MA (Motorcycle)
- MAN* 271/3275
- MTU Type 2
- Cummins* 20071/20072/20076/20077
- Volvo*, VDS-2, VDS
- Mack* EO-M+, EO-M
- ACEA A3/B3, E3, E5
- MB 228.1, 228.3, 229.1
- Detroit Diesel* 93K214
AMSOIL Synthetic 10W-40 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.
AMSOIL Synthetic 10W-40 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 and 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.
