In pursuit of real DATA related to Catch Can performance I've found that debris oil is only collected by the C-Can under WOT engine conditions that only last short periods of time.

Here's a video of a 2009 CTS V LSA SC V8, although slightly different, the PVC system in a SC is the same or very similar.

You'll see that after approximate 6 HARD Runs, to Max shift points and WOT, only about 1 cc of debris oil is accumulated.

This is one of the many reasons GM specifies a viscosity change before and after track days. A well maintain engine with QUALITY OIL will not excessively accumulate debris oil to cause engine wear issues. Oil changes are cheap insurance with ANY engine. Excessive Carbon will not usually occur in a properly tuned and performing engine.

I'm not bashing the aftermarket parts guys or quality of their items, and am only posting OBJECTIVE findings. I welcome any/all objective rebuttals.

Flame protection initiated.
