I like to make things more complicated than necessary, so I don't use just one oil. I use Hoppe's T3 which heavier and doesn't run much for the bearing points between the FE and the action and other contact points in the action - except for the hinge pin or stubs, which get lubricating grease. I use the lighter Hoppes 9 oil for moving parts like ejectors, safety slides etc. And I use Clenzoil as a wipedown oil.

This is a lot more interesting than just using one oil for everything.

Such a long, long time to be gone, and a short time to be there.
