New engine I have only around 200 miles on the engine. How can I tell when my engine is broke in
I'm wanting to switch to Schaeffer's moly oil. I just installed a oil cooler and would be a good time to switch.

My engine builder said to use conventional 10W-30 until 5000 miles so that the rings would seat. I switched to a synthetic at 500 miles and all is good. But if you are at all concerned about the warranty being honored on that engine, stick to what the rebuilder required.

The only break-in involved in a modern day internal combustion engine is ring seating. The rings are set in your first short drive. 4 to 5 heat cycles will ensure gasket sealing. If your tune is correct and it’s running fine, I’d go ahead and switch over to Schaefers now. I usually go 100ish miles on conventional and then switch over to synthetic. You’re good to go unless of course your builder has asked you to wait til xx miles…you don’t want to mess up a warranty, if there’s even such a thing here.
