I expect this condition to be 'normal' at 160K+ miles, regardless of oil type and oil change frequency. It also is determined by how often the engine oil gets hot enough to 'burn off' contaminates. A 20 minute ride to work, with the gear selector in "D", will not get the engine oil and the PCV hot enough to clean itself.

Using synthetic oils will extend the life of the PCV system, at least double the life of engines subjected to conventional oil.

My wife had an Audi A4 with the 6 cylinder engine. It had an oil temp gauge, and after getting home from work, the gauge was still on the cold side, a 30 minute commute. It had a clogged PCV at 90K miles.
