PRODUCT DESCRIPTION
AMSOIL High Performance Synthetic 20W-50 Motor Oil is specially
formulated to provide superior protection and performance in the most
demanding applications. It provides a wide range of protection in all
four-cycle gasoline and diesel engines, including pickups, RVs, cars
and off-highway vehicles and is ideal for use in high-stress vehicles
subject to stop-and-go driving, short trips, high temperatures,
frequent trailer pulling and off-road use.
Resists High Temperature
Vaporization
Conventional motor oils tend to "boil off" in high
temperatures, losing up to 25 percent of their original weight. These
vaporized oils circulate poorly, reduce fuel efficiency and contribute
to excessive emissions and engine wear. AMSOIL High Performance
Synthetic 20W-50 Motor Oil resists vaporization. In fact, according to
the NOACK Volatility Test, which measures the weight loss of an oil
due to evaporation, AMSOIL Synthetic 20W-50 only loses 6.0 percent of
its weight in high temperature service, surpassing rigorous European
standards set at 13 percent weight loss in high temperature testing.
The superior vaporization resistance of AMSOIL Synthetic 20W-50 keeps
engine wear, oil consumption and emissions to a minimum, while keeping
oil circulation efficient and fuel economy high.
Resists Oxidation and Thermal
Breakdown
Conventional oils oxidize in high operating temperatures, producing
sludge and deposit build-up that contribute to corrosion, increased
engine wear and decreased fuel economy. AMSOIL High Performance
Synthetic 20W-50 Motor Oil resists oil breakdown, maintaining its
cooling and lubricating properties and providing extended drain
intervals. It continues to provide maximum protection at temperatures
that oxidize conventional oils. The advanced heat transfer
capabilities and high lubricity of AMSOIL 20W-50 Motor Oil keep
engines running in their optimum temperature range for top performance
and long life.
Provides High Shear Stability
AMSOIL Synthetic 20W-50 Motor Oil surpasses the North American SAE and
European ACEA oil specifications for high temperature/high shear (HTHS)
viscosity. It retains its viscosity at temperatures and loads that
cause conventional oils to shear back to a lower viscosity. AMSOIL
20W-50 Motor Oil maintains an extremely protective viscosity of 4.9 cP
at 302°F (150°C) in the ASTM D 4683 High Temperature/High Shear
Test, significantly exceeding test limits.
Provides Low Temperature Protection
AMSOIL Synthetic 20W-50 Motor Oil maintains outstanding low
temperature fluidity, ensuring easy engine cranking for quick starts.
During sub-zero temperatures, it flows to all parts of the engine much
quicker than conventional petroleum 20W-50 oils, greatly reducing the
rate of wear and increasing engine life.
Resists Deposit Formation
AMSOIL Synthetic 20W-50 Motor Oil is highly resistant to oxidation,
running significantly cleaner than conventional motor oils. AMSOIL
20W-50 has a superior detergent/dispersant additive package that, when
tested after tens of thousands of miles of use in the crankcase, still
exhibits outstanding deposit control.
Inhibits Rust and Corrosion
AMSOIL Synthetic 20W-50 Motor Oil contains special rust and corrosion
inhibitors to protect iron parts, as well as copper, lead and aluminum
bearing materials.
Provides Extended Drain Intervals
AMSOIL Synthetic 20W-50 Motor Oil features a superior synthetic
composition and advanced performance additives, performing much longer
than competing conventional and synthetic oils.

- Ford ESR M2C 179A
- Daimler Chrysler 228.3, 229.1
- Mack EO-L, EO-M, EO-M+
- Volvo VDS, VDS-2
- Allison C-3, C-4
- Caterpillar TO-2, TO-3
- JASO-MA
MIXING AMSOIL
AMSOIL High Performance Synthetic 20W-50 Motor Oil is compatible with
conventional petroleum oils; however, mixing AMSOIL 20W-50 with a
conventional oil will shorten the drain period of AMSOIL 20W-50.
Engine oil additives or after-market products are not recommended for
use with AMSOIL 20W-50.
SERVICE LIFE
In personal cars and light-duty trucks with nonturbocharged gasoline
engines, change oil at three times the engine manufacturer's
recommended drain interval or one year, whichever comes first.
In turbocharged gasoline engines,
change oil at two times the engine manufacturer's recommended drain
interval or six months, whichever comes first.
In high-performance and racing engines,
change oil at intervals specified by used oil analysis.
In light-duty and nonturbocharged
diesel engines, change oil at two or more times the engine
manufacturer's recommended drain intervals if the findings of used oil
analysis support those drain intervals or six months, whichever comes
first.
In heavy-duty and turbocharged diesel
engines, change oil at two or more times the engine manufacturer's
recommended drain intervals if the findings of used oil analysis
support those drain intervals or six months, whichever comes first.
In marine craft and occasionally used
gasoline engines, change oil at three times the engine manufacturer's
recommended drain interval or one year, whichever comes first.
In fleet vehicles and industrial
gasoline engines, change oil at two times the engine manufacturer's
recommended drain interval or six months, whichever comes first.
If the vehicle is equipped with an
AMSOIL Oil Filter, the filter should be changed at 12,500-mile or
six-month intervals (whichever comes first) in gasoline engines and
7000-mile or six-month intervals (whichever comes first) in diesel
engines. Non-AMSOIL oil filters should be changed at the engine
manufacturer's recommended filter change interval.
