I hate to toot my horn, but my engine doesn't use a drop of oil between oil changes.

I was thinking of a conversation with my neighbor a while ago. He is the tech at the local Mercedes dealer (Penske Mercedes), and he told me that when the new / current V8 engine came out, you know the 5.5 liter DOHC V8 in the E550's, etc., he said that same were using a ton of oil, and they found the rings weren't seating.

The fix was for the techs to take them out and beat the **** out them....run them at a very high rpm for up to an hour. Apparently, it worked.
