- Issuing Committee
- Content
- This SAE Standard defines the limits for a classification of engine lubricating oils in rheological terms only. Other oil characteristics are not considered or included.
- Content
- This revision includes an additional acceptable method for determination of low shear rate kinematic viscosity at 100 °C, ASTM D7042. The inclusion of an additional method can enable engine oil producers to improve logistics and quality assurance.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.
