I run mine wet all the time, but you will probably find that as you get it broke in, you will not need to run it quite as wet as you do at first. Trial and error would be the best way to find where it's comfortable. If you still have issues running it lightly oiled, add a little more and shoot to test. If you get to the point where you still have issues with a nice heavily oiled carrier group, it's time to look at other contributing factors. My personal method is to diagnose from the cheapest factors up.... Use whatever works best for you.
