<p style="margin:2px !important;">Engine oils</p>
Description of Content

This Draft Uganda Standard covers test method that describes a bench procedure to simulate the oil aging encountered in Test Method D7320, the Sequence IIIG engine test method. These aged oils are then tested for kinematic viscosity and for low-temperature pumpability properties as described in the Sequence IIIGA engine test, Appendix X1 of Test Method D7320.
