NOACK Volatility Test is a Critical
Measurement of Motor Oil Quality
AMSOIL was the
first motor oil company in North America to use the NOACK
volatility test to measure motor oil quality and performance.
Although competing motor oil companies initially paid no attention
to NOACK results, the test has since become a critical measurement
tool throughout the industry.
Originally developed
and used in Europe, the NOACK volatility test determines how
much weight an oil loses through volatilization. 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 302 degrees Fahrenheit
(150 degrees Celsius) 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.
The lower the number, the better the oil resists volatilization.
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 (thickening). If those large, heavy molecules are
chemically unstable, they may also break down and form deposits
on component surfaces, further inhibiting the release of heat
into the oil stream.
Because their formulations
minimize the quantity of impure, irregular molecules, synthetic
motor oils are generally more resistant to volatilization,
allowing them to perform better than conventional oils in
the NOACK volatility test. However, due to varying qualities
of base stocks and additives, not all synthetic motor oils
perform the same in the NOACK test.
Modern engine designs
generate more heat than ever, accentuating the importance
of the NOACK volatility test for determining an oil's ability
to provide an adequate level of protection and performance.
More horsepower, turbo chargers and aerodynamic styling have
created extremely hot environments that receive less cooling
from outside air, and high heat leads to oil oxidation, deposits
and thickening in conventional oils.
Because AMSOIL
synthetic lubricants contain only uniform molecules, they
are much more resistant to thermal and oxidative breakdown.
AMSOIL synthetic motor oils help keep components free of damaging
varnish, deposits and sludge.
Top quality for
the current API SM motor oils specification, gasoline motor
oils cannot experience a weight loss of more than 15 percent
in the NOACK test. AMSOIL Synthetic Motor Oils were exceeding
modern requirements over 20 years ago, while many current
motor oils still have a hard time meeting this minimal requirement,
increasing wear, fuel consumption and emissions.
As seen in the
graph, AMSOIL 10W-30 Synthetic Motor Oil (ATM) easily passes
the NOACK Test and falls well below the maximum 15 percent
volatilization (burn off) rate dictated by the API SM motor
oil specification, while the Royal Purple volatilization (burn
off) rate is over 11 percent and the Lucas Oil FAILS
the test with a volatilization (burn off) rate of over 40
percent.

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.
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.
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.
