Originally developed
and used in Europe, the NOACK volatility test determines how
much weight an oil loses through volatization. The more a
motor oil vaporizes, the thicker and heavier it becomes, contributing
to poor circulation, reduced fuel economy and increased oil
consumption, wear and emissions. During the test, the subject
oil is heated to 150 degrees C (302 degrees F) for a specified
period, causing the lighter oil molecules to boil off. The
results are reported in the percentage, by weight, of the
oil that evaporates.
Because they are
made from impure, irregular molecules, conventional motor
oils are more susceptible to the effects of heat. The small,
light molecules in conventional oil tend to evaporate (volatilize)
as the oil is heated, leaving large, heavy molecules behind
and leading to oil consumption and an increase in the oil's
viscosity. If those large, heavy molecules are chemically
unstable, they may also break-down and form deposits and component
surfaces, further inhibiting the release of heat into the
oil stream
Another
AMSOIL First
More than 20 years
ago, AMSOIL began using the NOACK volatility test as a comparison
tool and measurement of quality. Back then, nearly every oil
tested side-by-side with AMSOIL synthetic motor oils failed,
and those that passed barely squeaked by. Other oil companies
paid no attention to NOACK results until Ford Motor Company
made it a requirement for service fill oils, validating what
AMSOIL had said all along.
Today More
Than Ever
Today's engines
are running hotter than ever. More horsepower, turbo chargers
and aerodynamic styling have created extremely hot environments
that receive less cooling from outside air. High heat leads
to oil oxidation, deposits and thickening in conventional
oils.
To qualify for
the current API rating of SM, motor oils for gasoline engines
cannot experience a weight loss of more than 15 percent in
the NOACK test. AMSOIL synthetic motor oils were exceeding
modern requirements 20 years ago, while many oil manufacturers'
current products are still performing just well enough to
make the grade.
AMSOIL
Still On Top
Because AMSOIL
synthetic lubricants contain only strong, uniform molecules,
they are much more resistant to thermal and oxidative breakdown.
AMSOIL synthetics are virtually impervious to breakdown at
normal operating temperatures and can be used in higher temperatures
than conventional oils without breaking down. AMSOIL synthetic
motor oils keep components free of varnish, deposits and sludge.
As the test results
show, this was as true more than 20 years ago as it is today.
The performance of AMSOIL synthetic motor oils in the NOACK
volatility test has improved slightly over the years, but
the superior quality and thermal stability of AMSOIL was as
evident then as it is now.

Premium AMSOIL
Synthetic Motor Oils offer the longest drain intervals
on the market, unsurpassed protection and performance that
effectively extends equipment life and improved fuel economy,
saving customers money at the pump and reducing the nation's
dependence on foreign oil.
"AMSOIL INC. warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL INC. products are used in full compliance with the company's recommendations and instructions."
AMSOIL
synthetic motor oils are formulated to surpass engine test
specifications, offering protection far greater than competing
motor oils for extended drain intervals. Most synthetic oil
manufacturers make no claim to extended drain intervals, deferring
to the maintenance schedule provided by the vehicle manufacturer.
With its unparalleled oil and warranty program, AMSOIL offers
consumers unprecedented protection and economics.

THE
NOACK Volatility Test
The NOACK
Volatility Test determines the evaporation loss
of lubricants in high temperature service. The more
motor oils vaporize, the thicker and heavier they become,
contributing to poor circulation, reduced fuel economy
and increased oil consumption, wear and emissions. AMSOIL
Synthetic Motor Oil resists high temperature volatization
better than other motor oils. AMSOIL Synthetic Motor
Oil maintains peak fuel efficiency and reduces oil consumption
and emissions.
