10、 The SAE Fluidity/Miscibility Grades defined in Tables 1 and 2 constitute a classification for two-stroke-cycle engine lubricating oils in rheological terms only. Other oil characteristics are not considered or included. Fluidity and Miscibility are measured according to test procedures described in

11、 ASTM D4682-87. These test procedures relate to the two common methods for introducing lubricating oils into two-stroke-cycle engines as defined in Table 3. Most oils will meet the requirements of one of the grades. In labeling an oil with its Fluidity/Miscibility Grade, only the highest grade may b
