    Rationale

    1. During the September 13, 2019 Sequence VI Surveillance Panel Conference call, the panel agreed to include a Test Method for viscosity measurements. The Reference Documents section has been revised and section 12.3 has been added to reference Test Method D445 for viscosity measurements. 2. During the October 25, 2019 Sequence VI Surveillance Panel Conference call, the panel agreed to add FEISUM to the method. Section 12.2 has been added to instruct how to determine FEISUM. Table 8 has also been updated to include precision estimates for this parameter and to correct a typographical error in the Variable Fuel Economy Improvement % hour specification.
