I put Mobil-1 15W-50 in the GTI at 5500 mi. (First scheduled change). 2000 miles later, I've used 1/2 quart. I'm happy with that. Others with the same car (VR6) changed earlier, and are still using 2-3 times as much oil as I am. Same experience with my mothers A6q -- wait on the first change, and low oil consumption. Another data point. Bob Davis bob@seg.net
