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
petrol 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.

- 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 petrol engines,
change oil at three times the engine manufacturer's recommended drain
interval or one year, whichever comes first.
In turbocharged petrol 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 petrol engines, change oil at
three times the engine manufacturer's recommended drain interval or one
year, whichever comes first.
In fleet vehicles and industrial petrol 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 petrol 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. |
