One thing to consider. You should mount it somewhere that is fairly easy to access so it can be removed and cleaned during oil changes. I pull my Moroso off and clean it every change.
Other than peace of mind, does it collect enough of what you don't want to make the task worthwhile?
Yes. And I don't know about the others but all you need to clean the Moroso is a big set of snap ring pliers. Been cleaning my Moroso 3 quart for Oh, about 23 years lol.
I wouldn't run one if it had to be sent away to be cleaned.
