New Approach to JASO Standardization of New Fired Fuel Economy Engine Dyno Test for the New JASO Gasoline Engine Oil Standard for Low Viscosity Grades (JASO GLV-1)

A fired fuel economy engine test procedure developed by Toyota was proposed to be a new JASO test procedure. Under the JASO Task Force, the fired fuel economy engine test working group was formed. Four test laboratories from oil and additive industries in Japan participated in the JASO Round Robin matrix to evaluate the repeatability and the reproducibility with four candidate reference oils. These candidate reference oils include two viscosity grades and two additive technologies that represent fuel economy engine oil technologies in the Japanese market. The project was successfully completed and the procedure was proposed to be a part of the new JASO GLV-1 engine oil standard.
