Honestly, try to stay away from the Pennzoil (and other lower grade)
filters. The anti-drainback valve is either sub-standard or they have holes
drilled in the base to allow for "quicker oil flow" (unfiltered at that).
The Mopar filter is seriously one of the best out there. We see too many
"knocking on cold start" problems. We install the Mopar filter and it goes
away (even happened to me - used to run Mobil-1 and they're an excellent
filter as well).
The other item could also be grundge in the oil pickup.

This one is Penzoil PZ-34. I have used the same kind before, but not in the
last few changes.
In case i wasn't clear enough, it doesn't do it at each start, it just did
it when i first started it up after i filled it up with new oil.
I did fill the filter with oil once before installing it. ("once"
meaning i poured oil in until it came to the top, but didn't keep filling as
the oil soaked into the filter.)
Pretty much my normal procedure. It might be that i usu get more oil in the
filter, but not drastically more.
The last oil change was done at the dealer, so it's possible that the sound
creeped up in 2 steps.
Thanks,
eric
