What actually is the Chrysler 6395 specification & is the current version M?
Since the majority of 5W-20 Grp II/III syn blends are listing both Ford WSS-MC930A and Chrysler 6395, the possibility that M1 5W-20, at the top of the "performance heap" being unable to meet this spec, is in the area of slim to none.
