Moly grease is just the normal LM grease which is called a lithium soap with some moly additive in.
In the vast majority of cases you can use either. It's only in things like constant velocity joints etc that it will make a big differance. Or someone said Morgan steering boxes.
In saying that to save space it's probably easier just to have one grease in stock so just buy molygrease.
The nice thing about the LM grease is that you can tell when it is dirty and needs changed but the moly grease is always black.
