Consumer Alert!
Due to the high viscosity, absence of additives vital to protecting an engine from deposits and wear, high phosphorus content, and labeling violations, PQIA has issued a Consumer Alert on Super Green Smokeless Motor Oil. Use of this product in virtually all automobile engines will likely cause harm to the engine.
The results of the tests conducted on this sample shows a viscosity of 41.5 cSt @ 100°C and 244 cSt @ 40°C. The viscosity @ 100°C is nearly 60% higher than the highest motor oil viscosity grade limit as defined by SAE J300. A Cold Crank Viscosity at -25°C (test temperature for a 10W-30) could not be determined. Based on these test results, use of this product could cause pumpability issues at startup in cold temperatures. In addition, the high viscosity could compromise fuel economy and the flow of lubricant to vital engine parts.
In addition to issues with the product’s viscosity, the phosphorus content at 2,123 part per million (ppm) is significantly over the 800ppm maximum allowed for motor oils used in modern engines. Use of a product with high phosphorus content can poison a vehicle’s catalytic converter and result in unacceptable tailpipe emissions. Adding to concerns about the phosphorus is the absence of any meaningful levels of calcium and/or magnesium, and zinc. This, together with the low total base number (TBN) indicates the product does not contain vital additives needed to protect engine from damage due to deposits and wear.
A Consumer Alert is issued on this product for labeling issues as well. Whereas the four bottles in the case purchased have a front label, there is no back label. The front label for this product identifies it as a “Smokeless Motor Oil”, but does not display any SAE Viscosity Grade, API Service Category, OEM specifications, or any other performance specifications. Without this information, a consumer cannot determine if the oil meets the requirements for their engine. Further, without this information, the label on the product does not comply with Regulation for the Method of Sale of Commodities specified in National Institute of Standards and Technology (NIST) Handbook 130.
Test Results and PQIA Assessment
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. >>More
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
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.
- This specification is expressed to one significant figure, therefore results between 550 and 849 are considered on specification.
