Hi Rafe, well I have a lithium grease tha is certificated by NLGI LB, and one of the test that the grease must fulfill is ASTM D4693 Low Temperature Torque @40°C 60 second Torque, the max. specitification is 15.5 N-m. Our grease is using Group I and the restult is 16.32 N-m. I think the best option is to chenge the type of basic oil but I just wander if adding PPD could help to improve the behavior of the grease to fulfil this test at low temperature.
