I used M1 red for several years without any bearing or component failure but yes, it always bled while sitting in the gun. This is the reason I stopped using it in the gun. I still have half a tube in my tool box for odds and ends.
Not an Amsoil fanboy but I was given half a case of their #2 purple lithium and while it is tackier than the Mobil, it has never bled and has not killed any bearings or components yet.
