It's probably the ZDDP, which is a very effective anti friction agent and required with 2 engines I own.

I've been running Mobil 1 and notice upper end chatter in the Z near the end of the oil's life (time-wise). I put an ester additive in during the last oil change with the same M1 oil to see if ester actually helps with valvetrain noise. If that doesn't do the trick I'm going to try Liqui Moly Ceramic next.

I used another LIqui Moly additive (lower tier than their ceramic) in a high wear diesel engine I own (not one that needs ZDDP) and it's significantly quieted.
