Assessment Summary

Use of this product in virtually any automatic transmission on the road today will likely cause harm to the transmission.

Labeling

The labels on this product are misleading and deceptive. The prominent display of the term “MD-III” could be interpreted by a reasonable consumer to mean it’s an automatic transmission fluid (ATF) formulated for use in vehicles recommending Dexron III/Mercon type ATF. This is because it is not unusual to see similar nomenclature on bottles of transmission fluid that are formulated for such use. Results on the sample tested show that this product does not meet the requirements of these specifications, nor for that matter of any other Automatic Transmission Fluid specification. 

In addition, the back label states it is “formulated with a unique combination of premium motor oil.” Importantly, motor oils are much different than ATFs and would not be appropriate for use in nearly any vehicle transmission currently on the road. The Viscosity of the sample tested is far below any ATF specification, as is the Flash Point. Further, it lacks the critical additives necessary for all modern automatic transmissions. Use of this product in virtually any automatic transmission on the road today will likely cause harm to the transmission.

As defined by ASTM, “The flash point is one measure of the tendency of the test specimen to form a flammable mixture with air under controlled laboratory conditions.” The flash point of lubricants is an important consideration with regards to the flammability hazard of the product.

Viscosity is a critical measure that determines how thick or thin a lubricant is. Viscosity is measured by several methods to determine the behavior of motor oil during cold startups and while hot at operating temperatures.  >>More

Antiwear (AW) additives help protect metal surfaces against impact friction and wear between moving parts in an engine. Such additives work by adhering to metal surfaces and forming a protective film between moving surfaces. The most widely used AW additive are chemistries containing phosphorus and zinc. Some lubricant manufacturers also employ the use of antiwear additives containing boron, molybdenum and titanium among others.

Antiwear additives are multifunctional in that they also act as corrosion inhibitors and, more significantly, antioxidants.

Although motor oil is subject to contamination from a number of metals related to wear, and abrasive material in the form of silicon when in use, new motor oil typically does not contain such metals at any appreciable levels. The presence of these metals (iron, aluminum, copper, lead, nickel, tin, sodium, potassium, etc.) in a new motor oil can indicate contamination from used oil, rust, abrasives, and others introduced to the product during blending, packaging, and/or transportation. Such contaminants can be harmful to an engine. Some can also be part of an additive, such as copper or sodium, but these are not often seen.

*Whereas silicon in the form of polydimethylpolysiloxane is commonly used as an antifoamant in motor oil, such use typically does not exceed 10ppm in new motor oil. Levels much above indicate possible contamination with abrasive material, silicone-based sealers, and/or transformer and hydraulic oil.

Note1: Standards are established by API, SAE and others.
Note2: Test Method for metal analysis is ASTM D5185.

Viscosity is a critical measure that determines how thick or thin a lubricant is. Viscosity is measured by several methods to determine the behavior of motor oil during cold startups and while hot at operating temperatures. Motor oils must meet Society of Automotive Engineers (SAE) J-300 standards to conform to a specific viscosity grade. >>More

Viscosity Index measures the change in viscosity with temperature. Viscosity Index improver additives are used to optimize viscosity at different temperatures. >>More

Detergent additives help to keep metal surfaces in an engine clean by controlling formation of deposits (i.e. sludge, varnishes). Such deposits can harm an engine by clogging oil passages that lubricate an engine, increase wear and reduce engine performance. A blend of calcium and magnesium-based detergents are most commonly used. A shift towards increased use of magnesium was required to address the needs of new gasoline direct injected (GDI) engines.

Detergent additives also help prevent corrosive wear by neutralizing acids formed as a by-product of combustion and other processes in an engine. Total Base Number (TBN) is a laboratory test that measures an oil’s ability to neutralize such acids. >>More
