This is for my girlfriends 03 Jetta 2.0il burner. Her car right now has 126,000 miles on it. It burns about a quart every 2K. I'm not to worried about the Engine Flush dislodging anything big in her engine. I think Liqui Moly's R&D staff knows what they are doing. You can't beat $13.50 for a Synthetic Blend High Mileage oil!
