Just put some Pennzoil Conventional in my tiching 4.3 Its silent! Gonna run a 5000 Mile Oci and do a used oil analysis. I guess Pennzoil Conventional does quiet down noisy engines.
Its always been my understanding that a tick is the tilt of a collapsed lifter. Varnish could cause a lifter to stick in this position, and pub might cause it to be freed again.

The only thing that's higher than normal is the moly. And that's because they're using the "cheap" moly. I agree its mostly due to the fresh oil and the tick will come back.
