1 Using ASTM D 2983, additional low-temperature viscosity requirements may be appropriate for fluids intended for use in light-duty synchronized manual transmission

2 Limit must also be met after testing in CEC l-45-T-93, Method C (20 hours)

3 The precision of ASTM D 2983 has not been established for determinations made at temperatures below 40 °C. This fact should be taken into consideration in any producer-consumer relationship.
