more important is regular maintenance as needed.

We do UOAs at every oil change and beat this thing like a rented mule, and have very good UOA results, because as you mentioned OCIs appropriate to usage is important.

I have the big series-1 setrab. I hook up a fill hose and flush it with fresh oil until I see clean come out the return side.

I’m guessing this requires disconnecting both lines from the adapter plate. I applaud your dedication. I’d make a huge mess doing that.

I just run a version of the oem turbo engine cooler setup. It’s decently effective for my needs and it seems self draining.
