The American Society of Automotive Engineers announced:
The American Society of Automotive Engineers (SAE) announced the J300 standard in 2013 after the most recent revision of the viscosity classification. This section will include two new viscosities: SAE 8 and SAE 12, which add to the motor oil viscosity classification table. The purpose of this update is to meet the need of "OEM" automakers to provide standards for broader protection of some sensitive parts and to provide engine oils lighter than SAE 16.
According to the recent classification, the viscosity of these two degrees will be at least 1.7 and 2 centipoises, respectively. In addition, the kinematic viscosity of these two standards at 100 ° C will be 4 to 1.6 and 5 to 7.1, respectively. The overlap between these two viscosity ranges provides the proper conditions providing different formulations at these two viscosities. The introduction of such standards can be considered as a supply of light engine oils to reduce the amount of friction between engine parts because they lead to a reduction in fuel consumption in modern cars.
Noted, consumers are equally interested in using more advanced lubricants and expect that with the advancement of technology in propulsion, the lubricant consumed by them will be developed in a coordinated manner. Therefore, note that the two recently designed standards are unused to formulate more broken-down cars' lubricators.
As it is grasped, the requirements of the SAE J300 standard are related primarily to the rheological behavior of engine oil, and other properties of engine oil are unconsidered in these standards. Needless to say, we do not expect the introduction of lubricants formed on these standards to happen so soon, because at least until the middle of 2022, we will wait for the leading companies in the field of additives to introduce additives for this standard, and after that, by the end of 2022, engine oils formulated based on these additives will be set up to the market.
