Downloaded from SAE International by Dalian Univ of Technology, Monday, January 25, 2016 SURFACE VEHICLE J300™ JAN2015 STANDARD Issued 1911-06 Revised 2015-01 Superseding J300™ APR2013 Engine Oil Viscosity Classification RATIONALE This revision continues the process of extending the SAE Engine Oil Viscosity Classification system to lower high-temperature high-shear-rate (HTHS) viscosities by adding two new high-temperature viscosity grades – SAE 12 and SAE 8 – to SAE J300 with minimum HTHS viscosities of 2.0 and 1.7 mPa·s respectively. The benefit of establishing new viscosity grades is to provide a framework for formulating lower HTHS engine oils in support of the ongoing quest of Original Equipment Manufacturers (OEMs) to improve fuel economy. The 100°C kinematic viscosity (KV100) ranges of the new viscosity grades overlap to provide adequate formulating space for these grades. How to assign a single high-temperature viscosity grade to an engine oil with KV100 in the overlap regions is covered in Section 6 of this document. 1. SCOPE 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. 2.
