SAE J 1510 previewed the coopoerative effort of SAE, ASTM, API, and CEC in developing a universal classification for engine performance. SAE J 1510 provides a great deal of information on the properties of two-stroke-cycle lubricants.
SAE J 1536 is a classification in rheological terms only. SAE J 1536 is a companion classification to SAE J 2116. By use of both SAE J 1536 and SAE J 2116, any lubricant can be classificed in terms of both rheology and engine performance.
