Last few oil changes, (around 5000 miles interval), I've noticed the 210k T5 R engine used between 3 to 4.5 qt of oil, even with a pretty clean PCV system.
Before last oil change, I bought the tool and put in some new Volvo valve stem seals since I noticed intermittent blue smoke. At 8544 miles (drove 5500miles in 12 days) since my last oil change and the engine barely used 1 qt of oil, I'd call that a success.
