SAE J300 is a standard that defines the viscometric properties of mono- and multigrade engine oils, maintained by SAE International. [1] Key parameters for engine oil viscometrics are the oil's kinematic viscosity , its high temperature-high shear viscosity measured by the tapered bearing simulator , and low temperature properties measured by ...

SAE J300-2021《Engine Oil Viscosity Classification》第一版发布于1911年，代替SAE J300-2015。GB/T 14906《内燃机油黏度分类》等同采用本标准。 该修订包括一个额外的可接受的方法，用于测定100°C下的低剪切速率运动粘度，ASTM D7042。加入一种额外的方法可以使发动机油 …

2013年4月2日 · The equivalence of ASTM D445 and bias-corrected ASTM D7042 in determination of kinematic viscosity at 100 °C for a wide variety of engine oil formulations within the viscosity range covered by the current SAE J300 Standard has been demonstrated in the ASTM Research Report RR:D02-1741 and the ASTM Research Report RR:D02-1931.

Use only manufacturer recommended oil viscosity grades for your vehicles. The Society of Automotive Engineers (SAE) developed a scale for viscosity for both engine oil (SAE J300) and transmission oils (SAE J306). See SAE J300 viscosity table below. Engine oil viscosity refers to how easily oil flows or pours at a specified temperature.
