I appreciate the followup...thanks.

It appears that the infamous Dmax typewriter clicking various from engine to engine. I have read that HDEO brands sometimes affect the typewriter click. Some users have issues with certain brands while others do not have issues at all. So, it's a random occurrence, and it's not relegated to just one brand of HDEO.

In terms of Rotella T4, it's the protection it provides as well as the lack of oil consumption that is of primary importance.
