If I am recalling correctly this isn’t necessarily a “change” and I’m 99% sure it means we can use it in LT1’s as well. There is an oil thread somewhere on these forums where someone figured out the Mobile one FS 0w-40 now meets dexos R specs. That means it can be put into the LT1 (and any other newer GM tech engine calling for Dexos R and 40w).

This recommendation is simply to save money, but not necessarily in a bad way as the oil meets the specs and folks buying L87’s aren’t driving them on a racetrack (ie the reason to use Supercar as it may sheer down less bad versus FS).
