Disagree. When my CCV went bad I was going through a quart every 300 to 600 miles. Repaired the CCV and I went back to a quart every 1600 miles or so. Just changed my oil after 5000 miles. The previous change I used 10w60 at my indy's suggestion. I only had to add one liter of oil at 2600 miles. That suggests to me that the oil usage is due to piston ring coking which the 3.0 is notorious for.
