Likewise, I went to 0W40 Mobil One in my not vintage yet, 191,900 miles 560SEL. Got the oil at Wal-Mart and the only beef I have is that they had every weight except 0W40 in the 5 quart jugs. Bummer since the jugs are priced under $20.00.

I had no leaks since resurrecting the 560 and I've been running semi-synthetic since I got the car. I don't expect any leaks now, but will keep an eye on things.
