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 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.

Truth in Advertising: BP v. Royal Purple

The April 8, 2009 edition of Lube Report, a weekly email newsletter from Lubes 'N Greases magazine, carries a lead story by editor George Gill titled Truth in Advertising: BP vs. Royal Purple. As it turns out Royal Purple was taken to task by The National Advertising Division of the Council of Better Business Bureaus. The NAD recommended that Royal Purple discontinue making many of their performance claims due to faulty documentation and anecdotal evidence.

AMSOIL 20W-50 Motorcycle Oil is the result of extensive research, and it is specially formulated to excel in all areas unique to motorcycles, including high temperatures of air-cooled engines such as Harley Davidson® V-Twin, wet clutch lubrication, extreme pressure regions of gears and chains and rust common to short trips and storage.

20W-50 Motorcycle Oil
Viscosity Shear Stability (ASTM D-6278)
1. Oil's initial viscosity is measured.
2. Oil is tested under shearing forces.
3. Measurements are taken at the end of 15, 30 and 90 cycles.
4. Comparison to initial oil viscosity.
5. A flatter line indicates a better shear stability.

AMSOIL 20W-50 Synthetic Motorcycle Oil stays in viscosity while other oils drop from a SAE 50 weight into the SAE 40 range.


AMSOIL 10W-40 Synthetic Motorcycle Oil

AMSOIL Synthetic 10W-40 Motorcycle Oil (MCF) is a premium oil designed for those who demand the absolute best lubrication for their motorcycles. AMSOIL 10W-40 Motorcycle Oil is the result of extensive research, and it is specially formulated to excel in all areas unique to motorcycles, including high engine RPM, wet clutch lubrication, extreme pressure regions of gears and rust common to short drives and storage.

In high heat conditions, engine protection is not sacrificed with AMSOIL Synthetic Motorcycle Oil. It has the best high temperature film strength (see High Temperature Viscosity Protection graph below) of all oils tested and contains a heavy treatment of anti-wear additives to reduce wear regardless of the operating conditions (see Wear Comparison graph at right). AMSOIL 10W-40 Motorcycle Oil is thermally (heat) stable and contains maximum levels of oxidation inhibitor additives. It is extremely resistant to breakdown and engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.

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.
